Photos taken through the lens of the Piccolette Contessa-Nettel folding camera from 1926 attached to the modern Canon 5D SLR. The Zeiss lens, which is almost 100-year-old, is still capable of making sharp images, though the lack of coating produces strong lens flare under back and lateral lightning.

If there was ever a wrong way to take a picture, these photos show all of them. It would appear that the most common mistake is holding the backwards while looking into the camera. However, trying to take a picture with the lens cap still on has to be a close second. There are surveillance camera fails as well and other stupid or funny situations with people using their cameras :)
