This is not a big thing but I have taken a lot of pictures and I want to see how they will look in black and white. I could look at them individually in Windows Photo Gallery but I'd have to fix every one and put it back to it's regular color again. I've tried to adjust my monitor but when I set the Red, Green, and Blue to 0 I get a dark screen. I just want to select the ones I think look best in BxW without having to change the files. Any suggestions?
