Operationally for the camera (in this case, the P&S), is the idea basically that the usage will be like a normal camera w/o user intervention? That is, user points camera, pushes the button once, and the camera will handle the work of capturing both a near-IR and normal color image?
The online processor - what is the channel manipulation that happens? The images on the kickstarter seem to conflict. One suggests you're simply doing a swap of Red with Near-IR data, but another suggests that it would be the NearIR-R-G expressed as R-G-B processing that is closer to how color IR film operated.
Simon I work at museum and have always held an eye out for a cheap false colour IR camera, it can be used to help identify pigments or in some case reveal under drawings. I know this isnt the type of conservation you've planned but could you look into this as there are a lot of small museums out there that could make great use of the equipment?
Rob Getting a bit higher tech... What's the frared wavelength you are using? 650? Do you plan to add far infrared filters in the 750. 850 and 950 infrared spectrum? [Would be nice :-) ] What is the sensitivity of the CMOS sensor you are using, how many lumins? ..and finally,; Is there the possibility of stacking filters with your camera?
Jo When I take a plant photograph, where is the information to help me analyzing or interpreting the color of a photo regarding the plant health ?

Ross Can you put the filters on a pair of glasses, and use them without needing a camera?
J.M. Any chance of having a Near-IR only mode?
