Subject: Re: A question for color film users
I've gotten several responses by private mail suggesting Photoshop <sigh>.
That's easy enuf to do, and I can think of several ways to accomplish that.
I guess with color film, unless when uses tricky lights, this same effect
can't be accomplished. What's a notch filter?
A notch filter is a narrow band rejection filter. They reject a certain frequency while passing all others.
Sadly, they are bloody expensive, and not very big around.
