I used to use a skylight (clear) filter for protecting my lens, but I opted not to after reading a thread on here a while ago.
Skylight is actually considered a warming filter and adds a slight reddish/magenta colour to an image. Take it off the lens and put it on a white piece of paper and you'll see the colour cast. Digital cameras on auto WB will likely nullify the effect of the filter though, but if shooting on a fixed WB setting like daylight, the reddish cast will be applied to the image...
I use a B+W brand UV
/Haze filter on all my lenses (and the upgraded MRS
version on high end lenses). Since digital sensor filters reduce UV
, the additional UV
filtration isn't necessary. But I'd much rather damage a $50 filter than the front element of a $2,000 lens. I also use a polarizer to reduce reflections.
The last filter I still carry is a graduated neutral density kit with +1, +2, and +3 stops of added density. Not much use for aviation photography, but I do use it for nature/scenic work. Using a tripod, bracketing and HDR processing PS
will yield similar results, but metering, calculating and using fixed neutral density filters makes me think harder about exposure.
