Re: IR/UV related questions

I definitely know what you mean about the Alien Cam. I think it's one of the reasons I'm hooked on shooting beyond the human norm.

With a full spectrum conversion like yours there's endless chances to experiment. I've tried all sorts of transparent coloured plastic & glass, such as pencil cases, sweet wrappers etc.  as well as the more normal lighting gels & filters. Nearly all transmit IR - Yes, as Hank pointed out it's actually NIR we're concerned with - silicon as used in the sensors becomes transparent to IR above about 1150nm, so there's little response above about 1100nm.

I'm afraid my image processing skills are a VERY long way behind Hank's - I usually shoot JPEG (despite ALL the advise) as the camera does a much better job of processing the RAW data than I can, & I prefer to play with optics than computers (so that probably won't change).
