Your eyes are lying to you

Outstanding video, Todd! Would love to see more of it + all the hidden gems and tools you already found in Photoshop. The part at 12:29 where you talk about how the saturation slider in the vibrance tool makes use of a different algorithm while retaining the brightness is exactly why motion pictures look so good (in most cases) because in movies you will find the term "color density" coined to this function besides using subtractive vs. additive saturation. Again, great content!

In the color grading video side of things, we refer to some of your examples as the problems from Successive contrast, or Simultaneous contrast. If you're ever on a color grading forum someone will post either a green screen face or a face surrounded by green foliage and the "facebook critics" will without a doubt, come on and tell the poster that the skin is too green, or too yellow. This is why in a color grading suite that you should not have a colored wall behind the monitor- the eyes ( and brain ) will perceive the image in front of a color and influence how we see it. And correct temperature lighting, because we constantly white balance what we see. Color and luminance. Another consideration is the appearance of more saturation when the color behind the subject is a complementary color. We tend to say that it makes it pop. But the contrast means that visually for a natural skin tone - when surrounded with "teal" you don't need as much saturation. I saw this demo using the grade from the movie "Barbie", that looked like normal saturation on the subject. But when the hue was removed from the background - the girl looked almost Black and White. Human visual perception of colors - saturation and light is a constant study for me. Really interesting video Todd - thank you for making it.

This is so cool! Please make a photoshop tutorial - many would buy it!!!

Really enjoy your channel for not only the in the field content but also content like this. Great job!

Fascinating. Have seen a lot of material on colour theory, but this is the first item I've run across on how we perceive brightness.

[@kruuuber]

Hah! This is the explanation how split toning creates contrast in an image. Where you add cool colours to the shadows and warm to the highlights. We perceive it as higher contrast without changing the value of shadows and highlights. Am I getting this right? Because yellow and red are "brighter" and blue is "darker". Very interesting subject and great delivery. Thank you!

very interesting. Thank you.

Great video Todd

[@marcsoracco1209]

Thanks for the in depth look at color.....very good information and delivered in a no nonsense manner, easy to comprehend. I edit mostly in Capture One on my Fuji images, and only do pre printing edits in PS but that info translates over to C1 as well. Thanks for your excellent informative videos.....Happy Holidays to you and yours.

Very helpful, thanks Todd!

Very interesting

[@cartercooperpa]

Solid content, thanks so much!

[@rickfarber4243]

Thanks for a cool and provocative video. I'd be curious to get your thoughts on "subtractive saturation" adjustments that have recently been added to the color grading panel in Davinci Resolve. They say that it can increase saturation without increasing luminance, or something.

[@RandyPollock]

Am I'm the only one that saw A as brighter? I even when back to make sure I didn't hear Todd incorrectly when he said that B was brighter

[@apkossowski]

Agreed

[@Belas_Photography]

Yes indeed, one great video. I'm a big fan of using the luminosity channel in the histogram, but I haven't found a way to make this setting 'stick'. Would you know if it is possible to always have the histogram show luminosity and not RGB?

[@nevvanclarke9225]

I thought it was the other way around. I thought I was brighter because it's not in a shadow. You said brighter so I would've thought that a is brighter because it's not in the shadow of the cylinder or am I missing something or am I going crazy?

Great video, it seems to me that at video and audio is out of sync, is it just me ?
