This is less of a tutorial and more of a quick deep dive into converting color images to grayscale in Blender’s Compositor. There are several ways to do this, depending mostly on the color space being used. The first method is actually the one you shouldn't use, because it doesn’t take into account how real light energy is perceived by our eyes depending on the different wavelengths of light. I'm talking about using the Hue Saturation Value node, specifically by setting the Saturation value to 0. This has the effect of uniformly removing color components across the three RGB channels, resulting in a high-contrast black and white image where some detail might be lost. The second method involves using an RGB to BW node in Blender’s Compositor, which gives a more pleasing result and is especially suitable for renders produced in Blender or, more generally, in any context where you're working with linear RGB data, such as in Linear Workflow pipelines. ---------- 🇫🇷 Version textuelle avec captures d’écran et autres ressources ici : * https://www.francescomilanese.com/fr/tutorials-fr-all/tut-147-fr-b3d-color-to-grayscale-gamma-linear-srgb.html 🇩🇪 Textversion mit Screenshots und weiteren Ressourcen hier: * https://www.francescomilanese.com/de/tutorials-de-all/tut-147-de-b3d-color-to-grayscale-gamma-linear-srgb.html 🇷🇺 Текстовая версия со скриншотами и дополнительными materialami qui: * https://www.francescomilanese.com/ru/tutorials-ru-all/tut-147-ru-b3d-color-to-grayscale-gamma-linear-srgb.html 🇨🇳 包含截图和其他资源的文本版本在此： * https://www.francescomilanese.com/zh/tutorials-cn-all/tut-147-cn-b3d-color-to-grayscale-gamma-linear-srgb.html
