I'm about to delve into CSS for my galleries, and I've been reading here about templates that provide an "opacity" effect. I've looked at galleries with both Safari and IE (Mac), and I just cannot see what this opacity effect is.
Rather than point me to a gallery that uses it (or in addition, if you like :-) Could someone please explain in words what is happening when a gallery uses the opacity effect?
(BTW, I'm a fairly heavy Photoshop user, and I understand the concept of layer opacity, if this helps.)
Thanks Much!
