The Shrine in Infrared

pug8 · October 29, 2006

I had some time today to do some infrared photography. At the main shrine in town I didn't have my tripod with me, though, so I put my camera on a bench, resting it on a filter case.
The IR 92 filter gives a very purple image, and needs a longer exposure than the IR 76 (which I bought on Friday. Still no filter holder, though).

Now the IR 76 - the image comes out very red, of course. I got the most pleasing colours from the eyedroppers in Curves managaement.

Nice shots! Those filter names sound like the Fuji square filter series. Is this correct?

I live in Japan too and have picked up some Fuji square IR filters. I haven't been able to find a decent filter holder, so they are sitting useless in my closet. I would love to use them, so any words of wisdom you might have with regards to filter holders would be greatly appreciated.

Yes, they are the Fuji square filters. I don't have a holder either, except for my fingers.

I just hold them in front of the lens, in their cardboard holder; you just have to be careful not to let ordinary light seep in.

There are several grades of IR filters that let in different frequencies of infrared light. The IR 76 image looks mostly red, the IR 92 is purple. There are a few others; 92 requires a longer exposure time than the 76.

In editing, the colors can be changed to whatever you like. Admittedly, I'm no great shakes when it comes to editing in Photoshop, but for the IR 76 shot, I used the White eyedropper in Curves, clicking here and there until I got one I liked. With the IR 92 image, I chose to keep it mostly purple as an example to show you; you'll notice that it's focussing is different.

You can get rid of that purpley image easily in Photoshop, just drop the magenta tint down through selective coloring. I'm sure there are other ways to do it but I find that the easiest way.

Remove Color
I usually just remove color in PS (Control-Shift-U if I remember correctly).

I processed it as you would color infrared in PS.
Go to Channel mixer, Red channel, set red to 0 and blue to 100
Leave green alone, go to Blue channel, set blue to 0 and red to 100.
You can tweak this a bit to your liking, but I left it as the formula goes.
I hope you do't mind my repost.

Thanks, Fabs. That looks good.
The problem I have is that the version of Photoshop is Elements 3 - so I don't have the Channel mixer (as far as I can tell ;>þ)

edit: Oh, but I do! I must have downloaded as an add-on quite a while ago. I've never used it before, though.
