Quick question for anyone who has/does shoot IR pictures:

Did you remove the IR filter from the cmos/ccd? If yes, does it make THAT big a difference? If no, why not and how do you avoid super-long exposures?


I don't have a DSLR, just a plain-jane digi with basic shutter controls. My problem is that my exposure times get so long it is grainy as hell, but I am concerned with disassembling my camera and removing the filter inside. Also this is not a DEDICATED I.R. camera, so I don't really want to do that anyway, however I need to pass more IR to shorten up exposure times.

For a lens filter I am using the old exposed film trick. Two layers is sufficient to block the visible light, and passes a fair amount of IR but it just isn't enough.

Advice?



edit: for those who don't know... this is ir photography:

If it's not a dedicated IR cam i wouldn't take out the IR filter. And yes these are quite restrictive. If the exposuretimes still give you reasonably sharp images try lowering the ISO value to reduce the noise.

Holy shit, those are some amazing pictures! Makes me wish I was rich...

Anyway, I appreciate the info. Hopefully I can get a few to turn out and I'll post them up.
