We Will Not Use Photoshop in the Future

""What's the point? Pictures don't prove anything anymore. An image from an unknown source showing up at a very convenient time? No one would take it seriously.""

- Tachikoma, Ghost in the Shell: Stand Alone Complex

Despite any obvious or implied advances in computer technology, photographic and video evidence of any kind is automatically accepted as genuine and unimpeachable. The possibility that it could be digitally faked is never even considered unless the provenance of the evidence is central to the plot—and when it is proven, it is a great shock and surprise to all who were fooled by it.

Particularly ridiculous on the part of the show's creators because every show these days involves digital manipulation of some sort, right down to digitally adding the credits over the action and "fade to black." This usually includes the photo or video that, within the story, is being accepted as fact. Not surprisingly, it's starting to move into Discredited Trope territory as more and more people become casually familiar with digital manipulation.

It's still extremely difficult to fake these things digitally or otherwise. Not a year goes by without some fake UFO video appearing and subsequently being torn to pieces by over analyzers. Any competent effects artist or photoshop user will tell the difference quite easily. We're not there yet folks!

It's possible to digitally sign digital media to detect tampering, but nobody ever seems to nod in that direction. Its also worth noting that many higher-end, professional cameras shoot "Raw" format digital, which contains the exact visual data captured by the camera and cannot be directly edited; edits are contained in a separate file or the image is converted to an editable format.

Since the trope is so prevalent, only exceptions are worth mention: 

Anime and Manga
"CG Sinon: (referring to exercise machine) "I use it every day!" Real Sinon: "I DO NOT USE IT EVERY DAY!""
 * Mahou Sensei Negima:
 * This is what causes Negi and company to become wanted criminals—Fate had edited video footage of their fight in the Gates to make it look like Negi had destroyed the Gates instead of Fate. Unsurprisingly, nobody makes any comments on this.
 * Chisame comments that her own website's photos are 'shopped.
 * Averted in Starship Operators. Advertisements featuring computer-generated but photorealistic models of Amaterasu's crew members are aired on the Galaxy Network, and the ending features


 * Xenosaga Episode I and its anime adaptation had the heroes needing to acquire "tamper-immune" footage clearing their names of a certain crime, because it just so happens that the organization that they're getting in the way of tampered with a black box (which should technically be impossible) and footage of the ship they're on "committing" the crime. Fortunately such footage existed in the mind of their super-powerful Robot Girl, unfortunately, they had to go through what was practically a Mind Screw to obtain it.
 * Ghost in The Shell Stand Alone Complex:
 * The Tachikomas mention that nothing can be taken for face value, since it's so easy to falsify any form of data—even memories.
 * Disturbingly, falsified memories and data are Truth in Television. Just look at all the viral videos on YouTube out there. Shows like Attack Of The Show and MythBusters often go to lengths to point out if what happens in a video is actually real or staged with computer graphics. Technology has advanced to the point where it's not totally obvious what is fake and what is real—especially if the video is "filmed by an amateur."
 * Hackers such as the Laughing Man can even make themselves invisible by hacking into people's cyberbrains and editing himself out of their sight. So you can't even trust your own eyes! In one case, a couple of homeless men who have no implants are the only reliable witnesses because they are the only people who could see his real face. Even the cyberbrain-equipped police officers were hacked, and left unable to actually understand the descriptions that the men gave. Any attempt to sketch the Laughing Man resulted in a picture of his logo.
 * In the manga Cannon God Exaxxion both the invading Riofaldians and Hosuke Kano's resistance both blatantly manipulate footage to embarrass their enemies; they both accuse the other side of altering the footage they release to the public; and they both try to pass actual footage of "embarrassing" incidents off as enemy propaganda when possible.
 * In Gundam Seed Destiny, when Durandal uses footage of the Battle of Berlin in his reveal of Logos, the Archangel and Freedom Gundam's presence has been excised—which the Archangel crew and Freedom's pilot note to themselves.
 * To kick off the events of Pokémon: Zoroark: Master of Illusions, Corrupt Corporate Executive Kodai orders Zoroark to pose as the three legendary beasts of Johto and go on a destructive rampage. He then edits the footage to show certain landmarks being destroyed. An odd move, since the unedited footage alone should have been enough to support his claims, and all the editing does is allow the heroes to discover the unharmed landmarks and figure out that he's deceiving everyone.
 * Averted in episode 13 of Cardcaptor Sakura. Yukito sees a picture of Sakura doing something she couldn't have done without magic, and Tomoyo Hand Waves it as being a fake.

Comic Books

 * The graphic novel Batman: Digital Justice describes how video news footage can be digitally altered to "edit reality".
 * The prelude to Marvel's "Secret War" featured SHIELD agents interrogating Killer Shrike about a robbery they have him on tape committing. This is accepted as infallible evidence despite the fact that the Marvel universe is filled to the brim with shapeshifters, mind-altering psychics, and technological masterminds; if the Fixer can edit Godzilla into Bogart's role in Casablanca, he can frame Killer Shrike with his eyes closed.

Fan Works

 * Hilariously averted in the Mass Effect fanfic Media Firestorm, which has everyone's least favorite muckraking journalist (Khalisah Bint Sinan al-Jilani) trying to sabotage a Shepard/Tali relationship with yellow journalism. One of her attempts involves confronting Garrus with a photograph of his alleged adulterous relationship with Tali -- and Garrus immediately responding with an eyeroll, a snarky inquiry as to if Khalisah has completely forgotten what Garrus did for a living before joining Team Shepard (hint: he was a police detective), and then a detailed lecture on exactly why Khalisah's Photoshop technician is an incompetent hack. ("And oh, look at this! Either Tali's become a vampire, or else he forgot to put her reflection on the back panel over here...")

Film

 * In the movie Judge Dredd, a picture is found to be fake, with plot-significant ramifications. (Interestingly, the character who discovers this goes so far as to explain how they faked it, saying it was state-of-the-art... twenty years ago.)
 * The Running Man:
 * Altered video is used to frame Ben Richards for a massacre he actually tried to stop. Amusingly, they didn't even need to synthesize any video -- just to do a deceptive edit and redub his voice.
 * Later in the movie, Ben Richard's death at the hands of Captain Freedom is displayed for a studio audience. Not only is Ben Richards not dead, Captain Freedom had refused to fight him. The scene is actually being produced by taking footage of one of Captain Freedom's deathmatches from years ago and digitally editing in Ben Richards over the image of Freedom's actual opponent.
 * Mr. Smith Goes to Washington: Handwriting experts declare the forged documents, that show Smith bought the land where the Scout/Ranger camp was to be built, authentic. Jim Taylor either bribed the experts or hired an expert forger.
 * The Ninth Gate: the Ceniza brothers tell Dean Corso that forging an antique book is very difficult and has a low profit margin.
 * In Resident Evil: Apocalypse, We Will Not Use Photoshop in the Future is used in reverse. The video showing the truth of the virus outbreak is declared a forgery by the Strawman News Media. Here.
 * In Starship Troopers 3, after Sky Marshal Omar Anoke crash lands on a planet en route to Earth to give an uplifting speech after a major defeat, Admiral Enolo Phid uses a device that records her and transmits the image of Anoke in real time, saying and moving exactly as she is. She later said Anoke died in a religious terrorist bombing.
 * In the climax to Wanted
 * Inverted in Transformers: Revenge of the Fallen. Sam meets his college roommate, who happens to run a conspiracy theorist website about the giant space robots the government is covering up. Sam, who has one of said robots in his garage, hilariously tries to convince the four guys who have spent months blogging about it that it was Photoshopped.
 * It even unintentionally draws attention to this trope when one of them insists that it couldn't possibly be faked while, of course, we're watching it being faked.
 * By Hollywood moviemakers with one of the biggest budgets in the history of the medium at their disposal. The character is likely just meaning 'impossible' in the sense of 'who would spend this much money on such a hoax?'.
 * In District 9, the Mega Corp starts a manhunt for the protagonist by releasing a pixellated image of him supposedly having sex with an alien. They didn't even really bother with Photoshop, since the exact same scene (sans pixelation) appears in Wikus's own documentary film at the beginning, being obviously of the alien attacking him. It's blatant enough to be seen as Black Comedy.
 * Quite possibly one of the earliest examples of this is in WarGames when
 * Minority Report plays it straight at first when the protagonist finds a photo apparently of and does not stop to question its veracity, despite the fact that 100% accurate virtual reality was depicted as being available in shopping malls in only the previous scene; averted when
 * Somewhat justified considering
 * Just like in The Running Man, the hero of Fahrenheit 451 is shown to be chased and shot by the security forces despite still being alive and the people of the future take it for granted.
 * Played with in the third Spider-Man film -- Eddie Brock fakes a photo of Spider-Man robbing a bank, and fools the entire staff of the Daily Bugle. Peter exposes the photo as fake. Sharp-eyed viewers may note that the base photo Peter produces is one of his own photos from the Empire State University photography department. Brock not only faked the photo, but he stole it from his direct rival. J. Jonah Jameson is not happy about having to print a retraction.
 * Double subverted in Spider-Man: No Way Home. falls through in court, but enough of the public still buy it to put him and his at risk. This is why he turns to Dr Strange for help.

Literature

 * In the Uplift series by David Brin, their talent for special effects is one of the few advantages humans have over the eons-old Galactic cultures, who are apparently too stodgy and unimaginative to expect this sort of deception. Except, of course,
 * In Philip K. Dick's Do Androids Dream of Electric Sheep??, the religion of Mercerism is practised by using an "empathy box", a device which enables the user to experience the sensations of a man named William Mercer. Mercer is a Sisyphean figure, whose attempts to climb an enormous mountain represent humankind's struggle to arise from the fallen state that nuclear war has brought them to, while unseen enemies hurl rocks at him. The androids attempt to prove that the experience is faked and was constructed in a studio; therefore, they insist, the feeling of empathy that Mercerists experience is also fake, and human beings are not superior to androids.
 * In Iain M Banks's The Culture, it's mentioned that any recording could be created, making blackmail impossible. Usually. Ship Minds can record events in an unfakeable way—so if one of them is focusing on something you aren't meant to be doing, you are in trouble. (Even that can still be faked by other Minds, but they're generally held to be above suspicion.)
 * Honor Harrington:
 * Avoided at least three times: first when Honor is commanding her squadron of Q-ships, to make herself appear to be a merchant captain, second when the People's Republic of Haven creates execution footage more or less from whole cloth, and third when the escapees on Cerberus alter their communication signals to make it seem as if all is still well on the prison planet to enemy warships. At no time is this ever made out to be anything unusual within the universe. The execution footage is an especially intriguing example, as the good guys actually spot that it's been faked by analyzing its compression artifacts. They can't imagine why, however, because they have other reason to believe Honor has been executed.
 * In Torch of Freedom when
 * Averted in A Rising Thunder, Solarian Navy Admiral Filareta's immediate response to the sight of the Havenite Secretary of War speaking to him in real-time from the flag deck of a Manticorean superdreadnaught is to assume that it has to be a computer-generated image, because its simply not believable. His intelligence officer then runs a verification analysis and comes up with the result that nope, its genuine.
 * Digital manipulation is used once again in An Act of War, a short from the fifth anthology, In Fire Forged. In a complicated series of double- and triple- crosses, the protagonist (aboard a State Sec warship) has the transmissions modified so that the crew appear to be onboard a Solly merchant ship instead, and the uniforms changed to match. It's also used to
 * David Weber uses it again in the Starfire novel Crusade. The Aliens use a CG image to hide that their representative hailing the Terran ship is not human. The static in the image hides that the sound doesn't precisely match the image.
 * Avoided, of all places, in At the Mountains of Madness (written in 1931 by H.P. Lovecraft) where one of the protagonist's worries is that the photographic evidence of what he chronicles may be dismissed as clever fakes by the scientific community.
 * Similar fears are present in all Lovecraft's stories, which include a protagonist desperate to prove the existence of some kind of Eldritch Abomination to the general public. In In the Whisper in Darkness the aliens themselves seem to agree that everything the protagonist has gathered could be dismissed as cheap forgery.
 * Paradox by John Meaney has the protagonist subvert Oracles, humans who can "remember" the future, by simulating an entire, perfectly consistent but totally fake future for them and replaying it all in an instant using video projectors. Result: they can no longer tell which future memories are real, rendering all formerly perfect oracular advice suspect for that point on.
 * Ascending by James Alan Gardner has the Honest Camera, which was built by Sufficiently Advanced Aliens. Since less-advanced species like humans don't have the technology to doctor images taken with it, it is acceptable evidence in courts of law.
 * Sort-of subverted in Michael Crichton's Rising Sun. Right after the death of a supposed murderer whom a security camera had shown in the act, it is discovered that the brief part where his face was visible was modified, and that the camera had originally taped someone else committing the crime. However, at first the cops swallow the doctored tape hook, line and sinker. It's only after the Crichton-surrogate brings the tape to an audio-video wizard(an expatriate Japanese woman who immigrated to the US so she would not be ostracized for her deformed hand) that the deception is revealed; as she dismantles the image step-by-step she criticizes the arrogance of the Japanese editors who made the tape; obvious-once-revealed errors such as sloppy airbrushing and extra shadows - "They think we will not be careful. That we will not be Japanese."
 * In Dan Abnett's Warhammer 40,000 novel Titanicus, a member of Adeptus Mechanicus reveals something from sealed records which declares that the Omnissiah and the Emperor are not one, nearly causing civil war even in the face of invasion. When an adept escapes with video evidence showing that it was a power ploy on part of one member, the evidence is denounced as fraud—which, others point out, shows that things can be fraudulent, and so they do not know if the original evidence is true.
 * In the original novel version of Stephen King's The Running Man, incriminating or just embarrassing photos of the protagonist and his wife, which he, and most likely any intelligent person, recognizes as airbrushed, are displayed during broadcasts of the eponymous Deadly Game to drum up public distaste for his character.
 * Averted in Richard K. Morgan's Altered Carbon. An early plot point involves editing security camera tapes—not to simply remove an incriminating section, but to add in simulated footage of a character doing something incriminating.
 * During The Infiltration in Wraith Squadron, one of the Wraiths' most potent weapons is a "holographic overlay" computer program that can be applied to their master actor Face, converting his appearance and voice into an enemy officer's in ship-to-ship communications. It's noted that this was compiled by using the duty logs of the officer in question, which he kept in full holo due to rampant, unchecked ego. In addition, while their ship's computer is fast enough to run the overlay in real time, it takes a lot of resources—when forced by circumstance to field calls from his immediate "superior" and the Big Bad at once, Face worries that the computer will be overtaxed and cause the overlay to break down, with... problematic results.
 * In Planet of Twilight, an associate of the Big Bad fakes a holographic recording of a meeting with Princess Leia, in order to paint her as an out-of-touch Straw Political to the locals.
 * In Mostly Harmless, Tricia McKillian is filming an interview with an alien aboard his spaceship (on the way to Pluto) and occasionally moves the camera to show the window with the stars whizzing past, noting that the effect is impressive and would have taken all of five minutes to fake at home.

Live Action TV
""That won't convince anyone." "We don't need to convince them, just confuse them long enough for that ship to reach Vulcan.""
 * There was an episode of Max Headroom in which it was discovered and discussed that digital media, including images stored in digital form, are subject to new and insidious forms of manipulation, distortion, and outright fakery.
 * Star Trek: The Original Series
 * One episode was ahead of its time in this matter, sort of. Kirk was facing court martial for the death of a crewman when video footage from the bridge shows him pushing the wrong button on his captain's chair. Spock discovered that the computer had been, in fact, tampered with, and the not-so-dead crewman had altered the footage. It's never explained why no one else (including Kirk's attorney) bothers to mention the possibility before the story's climax, however.
 * Actually, it is mentioned. The reason nobody suspected that the footage had been altered is because the authentication encryption on the ships' records was essentially so complex that it would be virtually impossible to forge, and only two men had the cipher key -- Kirk and the dead crewman (who was chief records officer). Since the one man was the defendant and the other was the alleged murder victim, unless they theorized that Kirk was framing himself they had no reason to accept the records as anything but genuine. Of course, once it was revealed that the "victim" was still alive it was obvious to everyone what was really going on.
 * Another episode had Spock using a computer to convincingly create commands in Kirk's voice.
 * Subverted in Star Trek: Enterprise—the crew projects a hologram of a sphere-builder, and one of the Xindi calls it a fake. The humanoid Xindi that sided with Earth assures him that humans can't fake a hologram as sophisticated as the one being presented.
 * In the Doctor Who serial "Trial of a Time Lord", it's established the Magical Security Cam footage used in the Whole-Episode Flashback sequences has been tampered with, but we never learn what really happened.
 * In the episode "In the Pale Moonlight" of Star Trek: Deep Space Nine Sisko and Garak hire a forger to create a fake recording of the Dominion leadership. The person meant to be fooled immediately searches for and finds imperfections in the recording, revealing it to be a fraud.
 * Double Subversion when
 * Star Trek: The Next Generation:
 * One episode featured a plot which involved forcing a kidnapped Ambassador Spock to send a message. When Spock was rescued, they attempted to broadcast a fake holographic message instead.


 * There are a few instances where Data's photographic memory and ability to perfectly mimic voices punch massive holes in the Enterprise's security system, such as in Brothers when he commandeered the Enterprise and flew it off when called by a subspace signal to where his maker was.
 * In the reimagined Battlestar Galactica, a woman accuses Baltar of collaborating with the Cylons and planting a bomb prior to the Cylon attack of Caprica. Baltar gets thrown in the brig based on the security camera footage she provides. He is then released when Lt. Gaeta examines the image and finds it has been altered.
 * This particular incident had even deeper layers, as the forged evidence was deliberately made to look realistic on first glance, but be recognized as a forgery upon more detailed examination. The Xanatos Gambit in question was done to convince people that Baltar (someone who actually had collaborated with the Cylons, albeit unknowingly - he was being a traitor though) couldn't possibly be a collaborator, because why would the Cylons attempt to frame one of their own?
 * Diagnosis: Murder: Mark Sloan is convicted of murder in a borderline Kangaroo Court. One of the witnesses, a landlady, is used to authenticate forged handwriting. At no point is a handwriting expert called to testify.
 * These web pages summarize the episodes where Sloan is falsely accused and the evidence and/or accusers do not have strong evidence or use the trial by media technique., , , , ,
 * Flash Gordon: used in an episode where Flash must discredit a recording of a rift portal before the turns it into a nation wide story.
 * Babylon 5:
 * The episode "The Illusion of Truth" is based around an Earth Alliance propaganda operative acquiring interviews and other video footage to create a fake news story. There was no need to fake actual footage, but a lot of responses were moved around and taken out of context to sound incriminating.
 * In another episode the video communication of Clark proving his implication in Santiago's death is mentioned to have a digital authentication signature.
 * In the arc concerning Sheridan's capture and imprisonment, the EA interrogator notes that they want him to make a public confession, where a telepath can read him to ensure the veracity of the confession. He says that if Sheridan doesn't go through with it, they'll simply forge his signature and fake a recording, but know that some people will never believe it.
 * The season four finale, set in the future, had a scene where someone was using holographic recreations to produce fake and/or "politically convenient" versions of past events.
 * In the somewhere between quirky and bizarre (and set Twenty Minutes Into the Future) miniseries Wild Palms, photos and video are routinely faked; and when a character is asked by reporters, "Isn't it true that a picture is worth a thousand words?", with regards to a key piece of trial evidence, that character responds with a sneer: "You gotta be kidding me."
 * In the sixth season of The Shield, Vic Mackie comes into possession of video that shows City Councilman David Alcevada being raped at gunpoint, performing oral sex on another man. Although the photo is genuine, Alcaveda asserts that there's no authenticity, and issues a formal denial. "Which celebrity picture did you photoshop this from?"
 * Subverted in an episode of Family Matters, when video evidence convinces everybody on the jury except Steve Urkel, who figures out that it was edited to put the defendant's face on the real perpetrator's body.
 * Averted in an episode of The Wire, when Mayor Royce distributes photoshopped flyers showing mayoral hopeful Tommy Carcetti with a notorious slumlord. It's a desperate Hail Mary play that doesn't work in the slightest.
 * In the The X-Files episode "Deep Throat", Mulder buys a photograph of a U.F.O. from a diner waitress, only for Scully to have it checked and find out that it had been faked.
 * An episode of Star Trek: Voyager has a crewmember convicted of murder based on images supposedly extracted from the memories of the victim (a standard investigation technique on that planet). When the crew finds evidence that the images are fake, the aliens claim that's impossible.
 * To be fair to the aliens, the guy who created the fake had to invent a way to do it first.
 * An episode of Sliders with really quick Game Show-like trials with real death sentences, it's discovered a member of the crew edited a surveillance video of a crime, which he committed only to have someone to try tonight.
 * In Murder One, a sex video of defendant Neil Avadon using autoerotic asphyxiation is used in his murder trial. His attorney Ted Hoffman rebuts "They can do anything with videotape these days. They can make hubcaps look like flying saucers." This comes back to bite him when he finds a videotape of the murder, and needs to convince one of the conspirators to switch sides and authenticate it.
 * In the Stargate SG-1 episode "Collateral Damage", Col. Mitchell is accused on an alien planet of murdering a woman and, in fact, has explicit and terrifying memories of doing so. Given that planet's advances in brain manipulation, the entire episode is spent figuring out how and if those memories are faked.
 * Double subverted on CSI New York, in the episode that sent Stella to Greece. On discovering a plaster cast of a dagger supposedly buried with Alexander the Great, Mac initially assumes that it must have held a forgery. When carbon dating of a fragment of ivory from the dagger reveals that it's old enough to be the real thing, the trope is played straight and everyone acts as if it must be for real; the possibility that a forger might re-use ivory from some less-valuable or damaged antique from the same period never rates a mention.
 * An episode of Bonanza had a killer use old fashioned photo manipulation techniques using multiple exposures to fake a picture to give himself an alibi because "photographs never lie."
 * Lois and Clark had an interesting case. A tabloid reporter got a real picture of Lois and Clark in a hotel room while he was still in his tights. However, she drops the camera, ruining the film, and has to resort to Framing the Guilty Party. Jimmy discovers that the pictures were doctored just in time.

Tabletop Games

 * Shadowbeat, an early supplement for Shadowrun, provided game rules for playing non-criminals such as rockers, reporters, and professional athletes. The section on reporters not only provided rules for faking still or video evidence in support of your stories, but also the odds of such bogus pics being identified as fake when they're submitted to the newsnets.

Video Games

 * In the original Command & Conquer: Tiberium, a journalist is covering a attack on civilians by The Good Guys - we then cut to a scene with that very same reporter in front of a green screen in a small studio. The Big Bad comes walking in, starts discussing how to spread the lie - then notices that the camera is still on and shoots it, ending the scene. Also of note is that the game takes place in 1995 or so, so its not the future, and green screens are the best we've got.
 * In addition, it's worth noting that when Nod is filming anti-GDI propaganda it often isn't faked; in one case they just paint one of their own Flame Tanks in GDI colours and film it burning down the nearest village.
 * Also used in the sequel, Tiberian Sun, where you had to take over a GDI base and use their units to attack a local Mutant community. Ironically most of your vehicles appear painted in Nod Colors on-screen, but people still believe it's GDI. It's likely done because, in a world where you have space stations, it's fairly easy to photoshop evidence, so they had to use actual witnesses.
 * A critical scene in Mass Effect hinges on the use of an audio file recovered from a geth soldier that implicates Saren in the attack on Eden Prime. Nobody questions it's authenticity, at least on-screen. Though, as you arrive in the middle of the evidence being presented, it is plausible any authentication process would have been completed already.
 * In Knights of the Old Republic, you present an incriminating recording to Jolee, and he snarks that he saw a holovid once with a Mandalorian dancing with a rancor—that doesn't mean it really happened.
 * Both averted and upheld in Knights of the Old Republic 2, when you're confronted with a voiceprint-coded lock. Your only two ways past it are either to locate several recordings of the lock's now-deceased owner speaking on various topics and use that as raw footage to splice together separate words to create a recording of him speaking the code phrase.... or else to trick a nearby robot that has a voice-synthesizer capable of perfectly replicating voices to do a voice imitation of the dead owner and then secretly record him.
 * Subverted in Front Mission 3, which takes place in 2112. The explosion that happened in Yokosuka base in the beginning of the game was released to the media as a gas explosion, complete with videos. The media suspects that it's forged. It is.
 * There's also the hilarious scene where an old soldier you run into sends you a picture of himself kicking a Wanzer in half. Surprisingly, some of the boys don't recognize it for the obvious edit that it is.
 * In Super Robot Wars Z, the protagonists, while split up, are shown footage of the other side engaging in morally reprehensible acts, which causes them to come to blows when they meet back up. The matter is resolved, but not before it's used to justify the Freedom vs Impulse battle from Gundam Seed Destiny.
 * One of the puzzles you could come across in Ripper involves an image supposedly taken from the protagonist's girlfriend's mind, IDing the titular killer. Your task: put it through an image analyzer and prove that it was faked.
 * There's also a puzzle where you had to break into a secret lab locked by a voice recognition system. Your task is to track down the owner of the lab, record a snippet of her voice, then alter it to say what you need it to say to unlock the lab.
 * In Final Fantasy XII the heroes use a speech altering device to make it sound like they had a VIP on board. It worked even though the person doing the impersonation was a bit tongue tied.
 * In Famous 2 inverts this when you take photographs to reveal the Big Bad's plans. This should have turned the populace against him, except that he quickly retaliates by claiming it was all faked. While the populace still doesn't trust him, it's enough to save him from a lynch mob.

Web Comics
"Cool. After the Hypershop "Awesomator" filter I can't tell that these are interns goofing off in the lobby."
 * In Schlock Mercenary, the Government Conspiracy frames a major character only to have the tampered evidence immediately blow up in their faces due to their technical ignorance. ("There's a pattern to those?")
 * Later Ennesby warns Tagon about sound editor possibilities... not that this is needed to land Tagon as deep into it as his foot sticks in his mouth all on its own half of the time.
 * From the Planet Mercenary twitter comes a picture with comment:

"Doodle: This is obviously photoshopped. Have you ever seen me smile like this?"
 * A fantasy variant is found in Dominic Deegan, where an unscrupulous elemental mage captures innocuous phrases on the wind with his magic, then alters them to sound far worse than they actually were. He uses this to break up relationships of women he's interested in so that he can sleep with them on the rebound. His attempt to use it on Luna fails, however, because both she and Dominic are well aware of what he can do, and refuse to trust the veracity of his "evidence".
 * Justified in Buck Godot: Zap Gun for Hire where a video feed is faked, but it's hoped everyone will buy it because nobody would dare interfere with the communication channels' security systems.
 * There is—well, was—a deviantArt comic that put a lampshade on this trope; the main character, Doodle/Zachary, was sent to the principal office. Said principal accused him of murdering another student and shoves a picture of Doodle killing her. Doodle's response?


 * What makes it hilarious is the fact that the picture showed a poorly drawn smiley-face on it.
 * In Let's Destroy Metal Gear! (again) after Snake finishes taking pictures of the Ray, Otacon claims "There's no way the U.S. Government can deny this!" Snake however just points out "Wouldn't they just say it was Photoshopped or something?" leaving Otacon speechless.

Western Animation
"Terry Fitsgerald: This is bullshit! Merrick: Of course it is."
 * In The Boondocks, Huey gathers evidence that his Granddad's new girlfriend is really a "ho". When confronted with the pictures in front of Granddad, his girlfriend says they were photoshopped, and Granddad believes her. Until her pimp shows up.
 * In the HBO Spawn, Jason Wynn has one of his employees create a photoshop of Terry Fitzgerald selling arms to terrorists. Later on, Wynne sends Merrick and a couple other agents to kill Fitzgerald. Merrick confronts Fitzgerald with the photoshopped image, and the conversation goes as followed:


 * Parodied in Futurama. After the crew document the evolution of life on an alien world, a creationist reviews the evidence and admits, "Well, digital photographs don't lie."
 * Even worse, said creationist isn't called out when he presents what is obviously a whimsical artist's rendition of a hominid riding a dinosaur.
 * Alejandro from Total Drama World Tour used photo manipulation to trick Sierra into thinking Cody and Heather slept together.
 * In an episode of the Street Fighter cartoon, Bison has Balrog make a video of the good guys trashing a temple in India that would make Industrial Light & Magic jealous. They didn't even paste the good guys' likenesses over actors, and once the people look at the temple itself instead of the video they see it's perfectly fine.
