Simple gaussian blur shader using a kernel
This tutorial demonstrates creating a gaussian blur shader using a kernel and the GLSL shader language. The process involves creating a kernel, defining a sample distance, applying blur, and setting the pixel alpha. Images with different sample distances are displayed for comparison. Thank you for reading this helpful guide!

Creating a duotone effect in a GLSL shader
This tutorial demonstrates how to create a duotone effect in a GLSL shader using an astronaut sprite. The process involves converting pixel colours to greyscale, determining pixel brightness in HSV format, mixing shadow and highlight colours, and adjusting effect intensity. The final step ensures transparency functions correctly. Explore the full tutorial for complete guidance.

Tinting Shan Shui art with gemstone colours
Following on from the sepia post, I replaced the sepia colour with gemstone colours. I used emerald, ruby and sapphire RGB values from Wikipedia. I lowered the brightness of the gemstone colours so they were not to bright when combined with the greyscale image.
