Grainy Gradient Heatmap Photoshop Tutorial

This grainy heatmap effect gives a photo an abstract, retro vibe with its ultra-bright colours that resemble thermal imaging. In this tutorial, I’ll show you how to create it using three examples, each with a different colour scheme. First, we'll convert the photo with a gradient map to generate the surreal colours, and then the addition of some blur and grainy filters really helps to enhance the effect. #graphicdesign #gradientmaps #tutorial #heatmap
