Short Summary
Main recommendation: Use a set of free online tools to check whether a photo is real, edited, recycled, or placed in the wrong time or location, treating each tool's output as a lead to investigate rather than proof. The video presents ten sites ranging from photo-editing detection and reverse image search to map, metadata, shadow, and fact-checking resources.
Key Points
- The list, in the order given, is: 10. FotoForensics (error level analysis for spotting edited areas); 9. Bing Visual Search (reverse image search for finding earlier or cropped versions); 8. Yandex Images (reverse search strong at faces, locations, and profile pictures); 7. SunCalc (checks sun position and shadow direction against a claimed time and place); 6. Wikimapia (crowdsourced map with user-added descriptions of places); 5. ExifTool (command-line tool that reads hidden file metadata); 4. Forensically (browser tool with error level analysis, clone detection, and noise analysis); 3. Snopes (fact-checking site running since 1994); 2. AllSides (rates news outlets on a left, center, right spectrum to compare coverage); 1. Bellingcat's online investigation toolkit (open-source intelligence tools for images, video, locations, and people).
- Error level analysis (ELA), used by FotoForensics and Forensically, highlights areas compressed differently from the rest of an image, which can reveal pasted or retouched regions.
- The video stresses that these tools show where to look rather than delivering a verdict, since someone can recompress an image to hide editing traces.
- Reverse image search can reveal that a viral photo is recycled from an earlier date, which exposes a false caption even when the picture is real.
Details Worth Noting
- Concrete instructions:
- To check for editing, upload the photo to FotoForensics or Forensically and run error level analysis; look for areas that stand out in brightness or compression compared with the rest of the image.
- To check a viral image's origin, run it through Bing Visual Search or Yandex Images, look for earlier posts, and compare the dates to the caption.
- To verify a profile picture, upload it to Yandex to see if it appears on other accounts, dating sites, or stock photo sites.
- To check time of day, enter the claimed location and date in SunCalc and compare the expected sun position and shadow direction to the photo.
- To read metadata, run ExifTool in a terminal to view camera model, date and time, GPS coordinates, and software used; the video notes metadata can be stripped or faked.
- Before sharing a claim, check Snopes, and compare coverage of the same story across outlets using AllSides.
- The video says Wikimapia data is user-generated and not always accurate, and is most useful for small towns, rural areas, and industrial sites poorly covered by Google Maps.
- Bing is described as hit-or-miss for faces, while Yandex is described as strong for faces, locations, and objects.
- AllSides rates political bias, not accuracy, so a source can be biased yet accurate, or centrist yet wrong.
- Bellingcat's toolkit includes satellite imagery, flight tracking, ship tracking, and social media analysis tools.
Bottom Line
Free reverse image search, editing-detection, shadow, and metadata tools can quickly expose many fake or misleading photos, but none is conclusive alone, so combine several tools and cross-check claims before trusting or sharing an image.
