AH … you say "I was wondering if the warming/cooling changed the Values"... I interpreted the word Values to equate to Brightness (Artistically speaking in painting you have Values (brightness), Edge (a type of contrast), and Color (Hue in photoshop). Many interpretation errors.

So to answer more clearly, in the second image, I would expect changes in Hue and Saturation, but not in Brightness.
No they are from this image which for whatever reason I did not successfully attach. Sorry for the confusion. i feel like we are in the movie "Babble."
And it is a GREEN apple, no less. I got confused also because I thought for a minute you might have another image, but the hues you listed were similar to my green hues. I did not see red hues!! LOL

Ok, so now... looking at the numbers, what are you seeing? Might be worth putting the numbers on the image to make it easier to talk about, but you only had four areas so we are ok...

for what it is worth, the brighter areas in your image look warmer to me (though that is hard to pull from just the numbers) - but your numbers definitely show that the darker areas are more heavily saturated.

Hi Frank - hey, those were observations I came up with - I"m sure that those things change depending on lighting conditions, but it isn't about that so much as it is about using the eyedropper and looking at the numbers and seeing what is going on in a particular image. Seeing if there is a pattern that is taking place. The values (brightness) I think are pretty predictable and everyone sees them, but I think the other things are also predictable, but we see them more intuitively.

So anyway, it is just about looking at the numbers and thinking about what it is that they tell you.. For sure, there Are highlights and shadows and the question becomes, what makes them so? What are their characteristics? Is it more true if taken in sunshine? Is it less true if inside a house?
