Texture Manipulation & Management Series: Part 5
How image textures can be defined (and understood) by Frequency
How does texture = detail = frequency? How can we know it using the Contrast Pop ResolveFX OFX? That’s what you’ll learn today, from the basics to advanced Frequency Separation node wrangling. 😉
All digital video and images have a “Spatial Frequency” domain—the rate and amplitude of grey value or colour variations over the image plane—described in sine waves (Fourier). An image’s Optical Transfer Function (OTF) and Modulation Transfer Function (MTF) measure and clarify its definition, resolution, quality, acutance (sharpness), detail-to-noise ratio, and more.
Episodes 5 and 6 of this series explore the concept of frequency in video. You will learn practical applications of this concept, as well as approaches and workflows.
