The water gave #12 away...;) Looks like youre off to a good start. I like the palm shots. :) Why dont you use the method i use to obtain "false-color" IR without the Photoshop fiddling. Two circular polarizers and different color filters or just the two polarizers. I use plastic lenses from a pair of polarized sunglass with a glass CPL filter. This allows me to fit 1 plastic PL lens(cut circular), 1 glass CPL, and 1 glass color filter of my choosing to 1 filter ring attachment. So no vignetting. ;) The polarizers are flush together, rotated until maximum light cutoff occurs. This will give you a Kodak ectachrome ir film look. Red foliage with deep blue skies. I added a red filter to 1 of my 2 "False color" IR pass filters for a different color format. I also take a White-balance measurment with the camera from the leaves with the filter on. Gives me an extra color set Below are test photos i took to inspect what happens to my color channels when i use the filters. I used my plain CPL Ir pass filter(auto whitebalance) and my other CPL IR filter with red addon(auto WB and Custom WB)
