I hacked together a little analog film emulation tool in Javascript. It's based on the awesome work of Pat David. I wrote it mainly to play with some new tech but I liked the result enough to share it with you. You can try it here.
How the Film Emulation works
I guess the most interesting part for most people is the actual film emulation code. It's using Color Lookup Tables (cluts).
So in simplistic terms:
For every pixel in the image
Take it's color values r, g, b
Look up it's new color value in the lookup table
r', g', b' = colorLookupTable[r, g, b]
Set the pixel to the color values (r', g', b')
In practice there are a few more considerations. Most cluts don't contain values for all 16 777 216 (224) colors in the rgb space. A simplistic solution to this problem would be to always just use the closest color (nearest-neighbor interpolation). This is fast but results in very ugly banding artifacts.
So to keep things fast I use random dithering for the previews and trilinear filtering for the final output. The random dithering is probably a suboptimal choice, but it was easy to implement.
You can find more details about how the lookup tables were create on Pat Davids website.
