Anyone got any ideas as to better represent each image in an RGB sequence so as to better represent the wavelength at which it was taken. i.e. L2 isnt classic R (255,0,0) L5 isnt G (0,255,0) and L7 isnt B ( 0,0,255 ) - so to truely use the images we get in the most appropriate way - we need to use different channels - or perhaps a combination of layers multiplied by something etc etc.

http://www.mxer.com/sandbox/wavelengthtoRG...lengthToRGB.exe rather excellently converts from wavelength to RGB value as a starter for ten.

Any ideas?

Working off a spectrum is fine - if you have L2,3,4,5,6,7 - but when you just have L2, 5, 7 or L4,5,6 - youre best bet is always going to be just merging them as channels in photoshop - the challenge is - how to best represent the actual wavelenghts of the filters for each of those images - especially L2 and L7. I've got the RAD files properly converted using teh neuences of each filter now - I'm getting images very similar to that of nasa - just slightly colourifically different if I use L2 or L7 instead of L4 and L6 respectively. L4,5,6 comes out PERFECTLY



- one of my favorite images of the whole mission - theres two frames there - L4,5,6

However



- this is using L2,5,6 - see the slight hue to the image compared to the NASA PAO release - that's almost certainly due to the difference between L2 and L4. I guess I could just sort out a levels-set that compensates that much - and ditto for L257 as well - but I'd rather represent each level more accurately.
