Quick question about a skylight (1B) filter

/me hands Dan a ladder and holds his shovel while he climbs out of the hole

no worries mate, I'm not the type to take anything on an internet forum that way, I tend to imagine phraises such as "as you well know" being said in a mock scolding voice by default.

actually I'm quite flattered that you think I'm a competent photographer

you are quite right of course, pointing into the sun with a UV filter on is a recipe for all sorts of loss of contrast, ghosting and goodness knows what other evil nasties.

what gets to me, and the reason why I jumped up and down perhaps a nats more than I should have back then, is the insistance by some that the presence of a filter degrades the quality of the image regardless of the position of the sun. Technically it's true, place any real piece of glass in front of your lens and you will get refraction induced problems, but as long as those problems are less than one pixel across you'll never see them.
