![]() ![]() The instructions for doing that are inside the brackets. Instead of a telling Affinity to make noisei type noise, the equation is telling it to make perlinsc – another type of noise. What you’ve got is the command at the beginning to produce noise followed by how to do that in brackets, with the “instructions” inside the brackets separated by commas. Think back to lesson 2 and the equation we wrote for Basic Noise 2 which was noisei(x,y). It’s a little bit intimidating but it can be broken down fairly simply. Select the Simple Perlin Noise preset from the Equations preset drop-down list. ![]() Do this via, Layer>New Live Filter Layer>Colours>Procedural Texture. So, Filters>Colours>Procedural Texture means click on the Filters menu, click on Colours and then select Procedural Texture.īefore we dive in and start tweaking, let’s take a look at how the Simple Perlin equation is put together.Ĭreate a new layer via Layer>New Layer (or click the chequerboard icon at the bottom of the layer palette)įill with your foreground colour via Edit>Fill with Primary Colour.Īdd a LIVE Procedural Texture filter (so we can easily edit and save new presets). it means go to that menu (Layer, Edit, Filter etc) and select whatever follows. NOTE: Menu convention: Where you see "Layer>New Layer", "Edit>Fill eith Primary Colour", Filters>Colours etc. ![]() Starting with the default Perlin Noise preset, you will produce several presets, gradually adding to your Procedural Texture tweaking knowledge. By the end, you should be in better position to spot different parts of the equations and have some idea of how to experiment with them. Tweaking (editing) Affinity’s existing Procedural Textures are a gold mine for finding new textures, gradients and effects. In this lesson I’m going to show you the subtle art of Tweaking. I won’t be taking you through the extensive textures and techniques I used to create the above image – baby steps! The purpose of that was to introduce you to the Simple Perlin Noise texture in Procedural Textures (which I did use) and just how potent Procedural Textures can be. Thanks to these founding fathers, Ken Perlin and Serif Software ☺ I can now produce images like this with Affinity Photo from an original photograph solely using procedural textures and default filters. In 1987, a small team of software engineers started producing affordable, user-friendly graphics software in the Jurassic era of Windows 2.0. In 1983 a computer science professor at NY University looked for a way to make computer-generated images look more natural. ![]()
