Re: Is the color infrared swap just 'art' - is there a good reason for it?

Interesting ! I made a little experiment.

I took these pictures of an halogene ceiling lamp using my 720nm filter.

I made a white balance so it looks like this :

Then I added the GRB3. the tint slide towards Yellow.

Then I took the Lee swatchbook and searched for the gels that cut the deep reds and very near infrared. Most gels look transparent but some appear blueish. I picked "primary green" and used it a s a filter :

So yes color variation is perceptible within the IR Spectrum. But unfortunately it seems two-dimensional. It goes on a straight line from yellow to blue. Not exactly a rich color palette... I still wonder what color It would look with a 850nm filter.
