Nikon D90 image overlay?
I just bought a Nikon D90 yesterday. Later, when I was shooting a portrait picture, there was an overlap image in one shot. Is this normal? settings: iso lens 18-55 F5.6 1 / 125 320 Additional details were still an image overlay even on the computer. happened once though. Is this normal?
It sounds like you accidentally double-exposure camera. And when you do that, it only lasts an image.
