It depends on your budget.
There are ones that look older, but they are $500-$800.
You can adjust whether the picture is black and white or not when you are processing the photos, if you are at Sam's or Walmart or something.
But if you are looking between $100-$300, look at a Kodak or Canon camera that you could find at Best-buy or Target. (Actually, you can find the $500-$800 ones there, too) There are ones that don't have the little see-through lens that are more modern, you might want those more. There's a really thin. black one that is between $250-$300 that is pretty cool, and it has video with sound. It has a YouTube sticker on it, and it's cool!
Like I said, you can adjust colors and brightness on the computer or while processing, I believe.
Just finished grade 5 and I'm lookin' for a camera, too
