I may be wrong and I am sure someone will correct me if I am, but no, not that I have ever noticed. A lot of people leave uv filters on to protect their lenses at all time. They are designed to filter out uv light, not all light.

Short answer: No. Long answer: Maybe. Quality varies from manufacturer to manufacturer and some have stronger color than others. If you're shooting negative film you would never see any evidence of a color cast because colors are corrected during printing. If you are shooting slides you might be able to see a difference in a side by side comparison between a filtered and unfiltered image. But the difference should be so slight as to be nearly imperceptible.

I'll weigh in on Jeff's long answer. I have seen a difference with transparency films. A little outdoors in open shade (mostly with Ektachromes I no longer use), but more indoors with flash. Some of my flash units do put out a fair amount of UV. How much you can detect, if at all, depends not only on UV content in the lighting (natural or flash), but also on your lenses. Glass inherently attenuates UV. This is why Nikon's very high end UV photography lenses are made of Quartz, not glass. Nearly all my lenses are primes with 5-7 elements. Those with zoom lenses having many more elements . . . often over a dozen . . . will likely not see much influence from UV content in the lighting. Much more of it is absorbed by all the glass in the zoom lens. -- John
