Photoshop Trolling

Photoshop trolling is prevalent in flat-Earth communities. The most common form involves finding a suitable landscape photo and using Photoshop or a similar app to turn it reddish as though it was taken on Mars. Then, the result is placed next to the original with a caption added to imply that the “Mars photo” was from NASA, and they faked it from the original.

Flat-Earthers will not bother confirming if the image was really from NASA. They cannot realize that they are being trolled —many memes containing such images spread in flat Earth communities as hoaxes.
