Stupid IR question

[LizM]

Ok, I've never messed with IR so forgive the stupid question.

Do IR filters just make everything look funky or will they help you shoot in low light situations too?

Depends on the filter:

You have to have an IR light source. An easy one is the sun. Many artificial light sources also emit IR. It just takes some experimentation to find out how much. The filters are used to block parts/all of the visible light spectrum to get a greater IR effect.

In low light situations I use a flash with a double layer of unexposed but developed 120 size E6 as a poor man's IR filter; it blocks most of the visible light, and lets IR through.

Ok. Thanks for the info. Its much clearer now!

of unexposed but developed

i read this in another post, but haven't tried it yet... if it the UNEXPOSED (ie transluscent) or the fully exposed (black) parts... for some reason i thought it was the fully exposed end the last time i read it

just need clarification before i expose a roll of film and get it developed
