I've decided to check out if being red/green color blind actually helps with spotting camouflage. I used my script on about a dozen pictures with some kind of military camo. At first there wasn't any significant change in the pictures, but I eventually came across a couple that actually made camouflage stick out from its surroundings. It's pretty interesting, all the surrounding foliage and trees will have a yellowish tint while the camo will have a bluish tint.

I tried investigating why these couple images worked out. It seems that the greens that have a hue above 90-ish become more blue and greens that are below that become more yellow. For example, in the first image below the camouflage has a hue range of about 90 - 100, and the surroundings are between 80 and 90. It's not a huge difference, but after you apply the color blind script to it the difference becomes much bigger. The foliage becomes a value of about 60 while the camo is around 240.

I made a simple script that takes a sequence of photos and combines them into a movie using ffmpeg. Donovan actually showed me the script, then I made a version specific to my computer. It's really basic, but it's been a big help so far working on the Haley film. I often have to render out my current progress on composites and post it to the Haley blog. Before I would render out my composite as a png sequence and then import to After Effects. Using ffmpeg quickens that process by a lot, plus the file size is super small. It will create a 1080p clip that's only around 1mb, without loosing any quality that I can tell.

Script:

#!/bin/bash

cd ~

cd /Users/Colin/Haley/2-16/png2

ffmpeg -i Scene2_shot_16_1%03d.png -r 24 -b 2000000 -vcodec libx264 -vpre hq -vpre normal test.Scene_2_1.mp4
