I gave a talk at the London Gophers meetup about building image filters like those found in Instagram. This talk covers what I learnt while building a reference implementation of a simple rendering engine using pure Go, with no dependencies. I cover various kinds of lookup tables, storage formats and although useful… why it’s probably a bad idea doing this in Go.

There is source code available at github.com/wayneashleyberry/lut if you’d like to try this out on your own images. You can also view the slides over here.
