Hmmmm.... And I quote:

"Skylight, Haze and UV filters are much the same.

They both block UV light. You can't see UV light,

but most films can. Those films see it as blue or

blue grey."

"That is if there is a lot of UV light they get

rid of it and if there is little, they don't do

much."

"I suspect that much of the longer UV near visible

may not be filtered out effectively and while the

amount and the wave length of the light may not

cause the damage that concerns the general public,

I suspect it is enough to have a photographic effect."

While perhaps technically not saying that "UV has

an effect on most photos shot in daylight", the

inference is surely there...!;-)

Though you do also say, "In short, for the most

part it does not make much difference in real life."

(referring to UV filters).
