OLD TOAD!!! Great to see/read you again; I have not been in these forums lately...
A Continuing Question: Yes, I look at the graphics of your two profiles and they appear very similar -- no difference to the naked eye -- BUT -- the sRGB shows it has 3144 bytes and the Camera RGB 1352. While the two diagrams display as the same size, isn't the content of the sRGB 2 1/4 times that of the Camera? Aren't the bytes a measure of content?
Continuing, please address my simplistic illustration of how this works with a projector:
Assume you are going to paint two identical walls that are currently photogrey, each is 8' high by 10' wide.
On the first wall you use two quarts of red.
On the second wall you use only 1 pint of the identical same red.
Won't the second wall be less ... intense....than the first?
If we translate this to images, consider a projector displaying a full size 8MB image, one that has not been image resized ("resampled") and also displaying the same image that has been resized (reduced) to one-quarter the size (from 8MB to only 2MB) -- wouldn't we expect the reduced image to display with less intensity, the same as the painted wall?
As I told Larry, above, this is far more technical than I care to be involved, but your help with answers will be appreciated.
