What I want to do
My attempt and results
First, a comparison of the same scene through three filters. I did an NDVI using the HSV method on Infragram.org, its just Blue - Red / Blue + Red, assuming that Infrared is in the blue channel, and visible in the red. I also did a Blue-Red to look at the channel differentiation.
Blue Minus Red
It seems like #26 has a slightly higher differentiation between blue and red channels. 19 & 25 seem very similar.
Questions and next steps
I took more extensive photos with #25 first, before taking the comparison shots. there seemed to be a few problem shots, not sure how bad they are:
