Filter Combinations

If I'm using a red filter (or any color) with an IR filter, does it matter which one goes on first? I have the red over the IR (or the red is the outermost lense).

And even though there is very little light penetration, is it necessary to take off my polarizer?

What kind of IR filter are you using? In most situations that I can think of the red filter would be redundant with an IR filter.

If you don't need the filter for the image, don't leave it on. It just increases the chance for flare.

OK thanks. It's a standard Hoya R72.
