Technical notes on oneshotcam

One of the biggest technical challenges of oneshotcam app was implementing retro film camera effects. A more technical post will follow, but shortly, the vintage film effects on oneshotcam was achieved by a combination of a few effects: color matrix (for color mapping), shaders (for film grain and halation effect) and some overlays for light leaks and dust.
React Native Skia library was used to be able to implement these components.
