I know next to nothing about these things, but I've had several occasions to use one. I've looked at a few sites to find the best one for my needs, but I'm left confused.
Is there a "best" filter for darkening the sky in shots where it would otherwise be blown-out? I've looked at Lee and Cokin and I use B+W's for my UV's. I went to 2filter.com, but the site is WAY less than useful for learning.
I like the idea of a holder vs a screw-on, but again, I'm confused about what to get. I don't want to spend $150 or more on this, so if a holder isn't within my budget, what suggestions would you make?
TIA!
