Are there specific filters you need to use on a digital camera? Or are they all for both 35mm and digital? Thanks!

Nik-

Filters are mostly the same for film and digital. Because the filtersscrew on to the end of the lens, when it is threaded, they are sold in different sizes.

You don't really have to use filters on your digital camera. Maybe a UV filter to physically protect your expensive SLR lens front element. You can create the effects of various filter with graphic editing software.

Possibly three are used mostly on Digi-cams Nik. The Skylight or UV filter to cut through haze and to protect the camera's lens..The polorizing Filter that cuts through reflected light and enhances colors...similar to your sunglasses. Also the Gradual Gray ND is used quite often to keep from blowing the highlights in Cloud and sky shots as well as water and desert or light colored rock formations. The problem with not using a filter to get the shot is that if you blow the highlights in a photo it is most times not recoverable. By being over exposed you lose the color information and no software on the market can regain it. Sure you can paint the colors back in but a filter will help you not only retain that info during a shot but can improve the color saturation or in the case of the skylight 1-A it will help remove some blue hues caused by the UV rays of sunlight. I use them and like them...The decision to use them or not is yours!

Also... while you can pick up a UV filter for around $15 US at your local BestBuy or WalMart, you might as well smear Vaseline on the lens. A cheap filter will measurably and noticeably degrade your photos. It's worth it to invest 2 to 4 times that price to get good multi-coated filters.

...Although I do admit to using cheap filters during the dry windy Spring season here in NM for inexpensive protection from the blowing grit and sandstorms.

And the Tiffen filters are good but inexpensive ones.
