Photoshop Mechanics / 001 Grayscale And Luminosity 30-59-11

Summary

Photoshop uses the RGB values of 30, 59 and 11, to simulate a more accurate representation of grayscale. These are the magic numbers behind the Color and Luminosity modes. This episode introduces some important concepts about RGB to Grayscale conversion. I plan to follow soon with an episode that covers multiple techniques for converting files to Grayscale.
