Now for this image I changes the levels so that there is less contrast between 000000 and ffffff. There are three main things that stick out to me.\

1. There are those odd rectangles in the background
2. The blue spots don't match up with the spots you see on the fish,
3. The top fin has an orange spot on it, no where else do you see an orange spot.

You can also see normal jpg artifacts between lines of high contrast (The fish vs. the white background)

If there are any questions, or suggestions on how this was done, or how to further it, just contact me.
