Infrared filters

I want to shoot my first roll of Kodak HIE this weekend. I have a Quantaray R2 red filter. Is this dark enough for good IR effects or should I get a Tiffen 25?

In principle, any red filter is fine, but the images may lack the

typical IR look (Wood effect, etc.). Even with a #25 filter you may be

disappointed. A #29 is, IMO, the very minimum, truly spectacular

effects will result with #87, which is visually opaque. There are a

couple of filters in between, which will still give good IR effects

while being transparent enough for aiming the camera through them, for

example an RG 665 (about #70, I believe).

Gary, I have used IR films for over ten years, shooting hundreds of

rolls. I use only a red #25 filter, and am very pleased with the

results. The darker filters are very difficult to see through, for

one, and also are intended more for the scientific, as opposed to

artistic, applications of HIE IR film. Here is a link to my website

where I have many IR images:

If you want to try a poorman's IR passing filter get one or two

unexposed but developed pieces of slide film. The emulsion contains

the red, green and blue dyes that block all visible light but pass

IR. I tried this with a color video camera and it worked quite

well. There is a site somewhere that talks about this but I don't

have the link here.

Good luck & cheers,

Gary,

Look up this address:

www.cocam.co.uk

Then click on infrared.There is information for you about infrared

photography and a link to the infrared newsletter

I believe the quantary R2 is the same as a 25A. Kodak HIE will give

very pronounced IR "wood effect" with the dark red filter. Be sure to

photography in bright sun to get the max effect with the R2. My

experiments with MACO indicates that the 25A gives no IR effect. I'm

using a Hoya R72 to get the IR effect. FWIW.

Set your camera meter at 300 and develop the film like Plus-x. Also

bracket+/- 2 stops for each shot. Be prepared for long exposure times

when printing. Don't forget to reset the focus on the lens to the IR

mark or if you do not have a mark, move the focus distance to the F5.6

DOF marker on the lens.
