fogging Infrared film

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

I'm considering on purchasing a new Canon Rebel 2000. I've been told the infrared sensor in the newer cameras will fog infrared film. Has anyone had this happen to them? My question is how bad is the fogging? I'm told that fogging may only occur around the sprockets, which if that's the case, then it can be easily cropped. Is the negative still printable? Any info about this would be appreciated. Thank you.

It seems to depend on your camera. Even with the same make and model, different individual cameras have different amounts of fog.

In general it is only along one edge and mainly in the sprocket holes. But it may etend into the image area by some amount. Sometimes not enough to be a problem, other times a good bit more.

One option is to pick up a older used, mechanical camera and use that for IR film.

On that Rebel, HIE infrared will fog along the sprocket holes, about 3-4mm. But 35mm is 24x36mm, and it will fog 'only' about 1/6 of your 24mm dimension. I have tested Rebels and Elans and have created 11x14 head and shoulder IR portraits using HIE, and have only had to crop the one edge. Knowing this, you can take IR images, leaving a little space along the bottom plane.

why not just buy the new camera and use your old equipment to continue shooting HIE with, that's what I did, my backup body is my infrared only camera now, it seems I use it more now because of the wonderful my old minolta XGM makes over my maxxuum's near silent operation..

a little more than my 2 cents...

The problem with fogging in Kodak HIE is that the film acts as a light guide like a fibre-optic device. If you take a conventional film out of the plastic canister in daylight, the film will hardly be fogged more than a few millimetres beyond the opening of the cartidge. With HIE, you may easily fog about a foot of film. Also, HIE is very grainy, which means you shouldn't sacrifce too much of your negative by cropping.

The film will be ok. I've loaded HEI in sunlight and have had no problems. Just sheild the camera and film with your back to the sun and the film in the shade of your shadow. James

like the others say, buy the new body use the old equipment for IR, i use a Minolta XGM for shooting HIE and have to tape up the back (too lazy to replace the felt) to shoot, but go with what works, instead of settling for the "naughty, naughty fog..."
