Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
The images at Victoria's Secret are fairly low quality -- JPEGs at 85%. However, just because they are low quality does not mean we cannot see what was modified. For example, the Error Level Analysis (ELA) should have all objects at roughtly the same coloring. If anything stands out as bright white, then it was the last thing modified since it is at a higher potential error level than the rest of the image.
