I was just watching a seminar about color grading in portrait photography and it also talked about luminosity, how it's processed faster than color, and how to account for it while color grading.
For artistic affect, it may be preferred to have near equal luminosity throughout the image so that the luminance variance doesn't allow you to "make up your mind" about the image before processing the color.
Interesting to so soon come across related studies without searching.
- Hnrobert42 6y agoI am interested in what you are saying. If I can ask for a favor, could you maybe link to examples of two different portraits: one with uniform luminosity and one without? I don’t really know enough about color theory and the terminology to imagine what you are describing. I don’t even know enough to properly search for example images myself. Hence the request. :-)
- Pyrodogg 6y agoHere's a link to the point in the video where this concept was discussed. It references two classical art paintings, and two photographs from the presenter. https://youtu.be/mC8ol2-V7Ck?t=2116 https://youtu.be/mC8ol2-V7Ck?t=2116
- Hnrobert42 6y agoThat’s awesome. Thank you!
- jacobolus 6y agoNit: "luminosity" is an incorrect term to use here. https://en.wikipedia.org/wiki/Luminosity https://en.wikipedia.org/wiki/Luminosity You probably mean "lightness", but you might mean "luminance" or "brightness", depending on the details. https://en.wikipedia.org/wiki/Lightness https://en.wikipedia.org/wiki/Lightness https://en.wikipedia.org/wiki/Luminance https://en.wikipedia.org/wiki/Luminance
- Pyrodogg 6y agoThanks, yea meant "luminance" throughout.
