I'm beginning to experiment with filters. I do not understand his topic fully but I have a few general questions. I shoot B&W primarily and with contrast filters but... -There is no negative consequence of using UV filters indoors, right? I mean besides the general consequences for putting an additional glass in front of your lens..flare..image degradation, etc. The intent of the UV filter is solely for protection. -I have invested in some Hoya HMC filters, but I've read that they can sometimes bind to lenses. To those who have experienced this issue, were you able to safely remove your filter?
