Hello,

I know some people in European & western photographers use infrared film.The temperature is cool not harm for infra radiation. In Bangladesh - it is humidity country.Temperature rises 68 degree F. Some people try to use this infrared film. I also processed it in HC110 developer 6 minutes in 24 degree C. But it is foggy.Can any one give me a time temperature for infrared 35mm film. I visited kodek infrared web site -it gives a clear vision how to expose the film with filter.But there processing chart is not clear to me.

Thank You Mohammad Irfanul Islam Darkroom Section Drik Picture Library Ltd E-mail:darkroom@drik.net URL:http://www1.drik.net http://www.drik.org mirror site in Europe (services.toolnet.org)

By "foggy" do you mean that the film edge, that should be clear, isn't? If so, then you possibly haven't taken the proper precautions with the IR film. The Kodak film is very sensitive, and need metal cameras and processing tanks. The Ilford film (SFX 200) is less sensitive.
