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).

I'm a bit of of both I guess, I'd like to process RAW data but I'm also into optical experimentation using non-conventional material(s) and/or vintage optics. Unfortunately this little cam doesnt have any RAW options, so its jpeg only anyway, but I'm enjoying it nevertheless, just the fact that it is even usable for this type of photography, after having removed the IR-filter, is rewarding by itself in such a sense.
