I have here an almost new Hoya Skylight 1B filter, both sides coated. It
seems to do nothing on florescent lights, nor looking through it at
daylight. I've never noticed any difference using it. Even the photos on the
case showing what it does don't look any different to me. I bought it
because I thought I needed it. I'm not using it now, likely it will sit in
my case until I have a situation such as salt spray, or a sand storm to cope
with. It does seem to have an ever so faint pinkish hue to it when it's on a
perfectly white surface.
Comments?

Sky filters are not as effective as UV for eliminating UV. They have a
lower cutoff point and will not turn yellow as will a UV when placed on/near
fluorescent lights. The only thing a Sky does is the pink tone warms the
photo to eliminate the slight blue cast in shaded areas. I used to use Sky
filters until I did a lot of reading on UVs. Now I only use UV filters when
needed.
