A first try at infrared photography (2 pics)
Posted By: tcom, 01-23-2009, 09:36 AM

I wanted to try out infrared photography, so I got myself a Hoya R72 filter, mounted it on a FA31 and put the lens on several DSLRs.

It works pretty well on a K100D, but on K20D and K-m, the IR cut filter is so strong, the exposure times are way too high.

Here are my first tries:

K100D, FA31, 1/60, f2.5, 800iso, Hoya R72, +2EV


K100D, FA31, 1/10, f1.8, 400iso, Hoya R72, +2EV


I guess the best would be to have either K100D or K20D modified by replacing the iR cut filter by an IR-filter.

They are not bad. In fact I like them.

Maybe I will try some with an R72 filter as well.

If you take more, post them. It's good to see experiences.

Thank you both for your comments.
