well if you shoot color, you can always adjust the RGB channels. for example using the RED channel only would be like putting a red filter on the camera. likewise by adjusting the RGB channels & their gamma you can pretty much get any color filter look in post provided you know what you are doing. learning about channel filters is a basic of the compositing & grading world FWIW.

I agree with Steve, here is a nice photoshop tutorial and for video you could use channel mixer in After Effects in its place.
