How to tell if a photo is AI generated
Start with where the photo came from
The most reliable question is not "does this look fake" but "who shared this first, and can I reach them?" A photographer, an outlet or a person at the event can usually say where and when it was taken. A screenshot with no name and no link gives you nothing to check.
Look at the account that posted it. A long history of original work is a good sign. A new account posting dramatic images with no other content is a reason to slow down.
Check for Content Credentials
Content Credentials (the C2PA standard) are a signed record attached to a file that can show who made it, with what tool, and what was edited. Drop the file into the Content Credentials Verify tool (the old address contentcredentials.org/verify forwards there) to read it.
Two honest limits. First, many photos have no credentials at all, and that does not make them fake. Second, credentials can be lost when a file is re-saved, screenshotted or re-encoded by a platform. A missing record is silence, not a verdict.
Run a reverse image search
Upload the image or paste its link into Google search by image (in Chrome, right-click and choose Search with Google Lens) or into TinEye. You are looking for an earlier copy, a caption that contradicts the claim, or the original photographer. If a "breaking" photo shows up years old, you have your answer.
A brand-new image will return nothing, so an empty result proves nothing either way.
Look closely at the image itself
Zoom in. Common tells include text that is almost-letters, hands or teeth that do not add up, jewelry or glasses that merge into skin, shadows that point in different directions, repeated patterns in crowds and backgrounds that melt together. Treat these as hints. Newer tools get many of them right, and real photos can show odd artifacts from compression or editing.
Also ask whether the scene makes sense: weather, signs, uniforms and landmarks can often be checked against other photos from the same place and day.
How Emera handles this
Every post on Emera carries a signed record (C2PA content credentials) of who shared it and when it went up. A Signed badge says exactly what was checked and nothing more. Reposts point back to the original post, so you can follow a picture to the person who first shared it. Emera does not detect AI images and does not tell you a photo is real; it shows you what was recorded so you can judge.
People also ask
Can an AI detector tell me for sure?
No. Detector tools give probabilities, make mistakes in both directions and fall behind new image generators. Use them as one input next to the source and a reverse image search.
Does a missing Content Credential mean the photo is fake?
No. Most photos online carry no credentials, and platforms or screenshots can strip them. Absence is not evidence either way.
Does a present Content Credential mean the photo is true?
No. It records who signed the file and what was done to it. It does not say the scene is accurate or that the caption is honest.
What is the fastest check?
A reverse image search. It takes under a minute and often finds the original or an earlier copy.
