Testing to emulate a thermal camera as close as possible with After Effects. As a reference, I used a video that was recorded with the FLIR camera. First I tried a tutorial where they use Photoshop, but it turns out that the Colorama effect in After Effects works just as well.
I still need to figure out a good algorithm that translates a color sample to a temperature value (click here for a simple example). There’s a few more details that I need to work on. For example, if you watch the real footage, you may notice the shifting in the color phase, as indicated in the right-side gradient bar. This is also accompanied by the shift in the high/low threshold temperatures. Hopefully I’ll get a decent-looking thermal camera effect for a piece I’d like to do.
