To do with digital cameras..
Not all digital cameras actually even have viewfinders these days. A viewfinder is the little hole one would look through when taking a photograph. Now, viewfinders have been replaced with a whole screen. Some (more professional) cameras still have viewfinders though, and they also have the screen.
technically in most modern cameras if they have a "viewfinder" then tend to be an LCD screen unless its an SLR or a proper D-SLR :P
old school... i remember when i had a camera and you had to stick this big film in it and wind it before each pic lol
It's the little window you look through when taking a picture....most people use the LCD screen though.
Whoa, I just realized I don't even know if my camera has one haha
