Using a histogram really does not tell you much about exposure.
Take this generated image whos red values represent from 255,0,0 to 255,255,255 now if I was to believe this histogram it would be telling me that its is blown
What is the different between this histogram and the first
It is made using the very same color red as you can see that very few of the pixels are even found at the far right.
Lets find out which pixels are at the far right, here I have select the reds midway and all the way to the bottom
Well none of those are even close to the right of the histogram, so how can I use the first histogram for those red that are selected to decide if my exposure is what caused them to be blown?
Lets look at the mid to the very top
Well look at that its only the very top that are found to the right and more importantly its only the very white that is found there.
So what is the histogram showing me with regard to the exposure and more importantly do I trust it?
Or is the histogram showing me the distribution of values of a processed image within a
color space
