The answer is: no more or less than on traditional film cameras.

You could fill a wall sized bookcase with tomes about photographic filters; but for our purposes we'll just concentrate on three, "UV", ND (neutral density) and Circular Polarizers.

Of course you have to have a digital camera that accepts screw in filters in order to use them. But even if you don't check read through this posting because the next camera you get may have that option.

First off check out this brief treatise about 3 of the most commonly used filters for digital cameras.

OK now that you know what's being talked about and have one person's opinion here's where I stand on the issue.

I do use a UV filter, all the time, because I take a lot of distant landscape pictures and there's always some haze that can be eliminated. And, it keeps dust off the camera's lens. I'd rather clean a filter, while on the camera, rather than risk scratching the actual lens.

As for neutral density filters, I never use them, but that's just me, for you they may prove beneficial.

I do make extensive use of polarizing filters because they enhance colors, especially the sky, and when clouds are in the scene it really makes them "pop", or stand out, and I like that.

Note the difference in the sky in the above comparison photos and you'll see what I mean.

Take a camera with you whenever possible, and look around, you'll find a picture somewhere.
