Building Instagram Filters With Go

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 if you’d like to try this out on your own images.

Here's a link to the slides
