Skylight or UV

Skylight would have a slight colour tinge and UV would most likely be rendered useless by the built-in UV filter that most camera sensors have.

If you want protection then either go with UV or one of the clear glass filters like Hoya's Protector range.
 
im interested in the answer also
 
A UV filter just filters UV haze in your images, and any decent modern multi coated lens will have a coating for UV anyway, so the filter wont do anything - except protect the lens of course.

A skylight filter has a slight pink or straw tinge. It's purpose is to eliminate blue casts caused by light reflected off that blue overhead sky canopy on images taken in the shade - not images taken in direct sunlight. It's most noticeable on skintones.

If you think of the sun behind clouds, all the light is bounced up and off that blue ceiling picking up a blue cast in the process, much the same way as flash picks up the colour of the surface it's bounced off.

Thank you,very much appreciated
 
Sorry... I should have said if you leave it on the lens all the time (a skylight filter) as a protection filter, in all conditions, other than on sunny days in the shade, the worst it will do is probably give a slightly warmer look to your images because of the slight pink tinge, and might give a slightly redder tinge to flesh tones, but it should be easy to correct that in processing.
 
wont your camera WB sort the colour cast out when you take piccy:thinking:
 
If you look at the Hoya range they do a Protector filter which is clear will not give the colour casts of a UV or skylight

Possibly, but that depends on how well the camera handles wb, and DSLRs still leave a lot to be desired there .My cameras don't for instance correct for the cast produced by shooting through tinted double glazing, so I wouldn't bet on it. A custom white balance shot should certainly correct for the filter, but then it would be easier to take it off in the first place. You should certainly be able to eliminate any casts in processing anyway, particularly if you shoot RAW.

Skylight filters will probably also lose you a little exposure, probably only around a 1/3 stop with one of the better ones - cheaper ones could lose you a bit more.

Skylight filters are probably more useful shooting film than digital nowadays, but I'm not a fan of protection filters anyway, preferring to always use a lens hood and a little care.
