What I’ve learned: Color management (2)


I’ve learned quite a bit from these two books.  My preference was actually for the second one, just because it was a bit more accessible.  The first one is very thorough and knowledgeable, but since I’m more interested in the application side of color management than the theory end, I found it to be a bit much at times.

Here’s some of what I’ve learned:

  • Of red, green, and blue, the human eye is most receptive to green.  Digital cameras often have twice as many green receptors as red and blue to account for this.
  • Working spaces like Adobe RGB and sRGB are just that: spaces for working on the images.  You keep the image in the working space as long as you and others are working on it.  My understanding is that the monitor profile translates from the working space to the monitor outside the photo editing workflow, so that the monitor profile never actually gets applied to the photos themselves.
  • In the digital age, it’s better to slightly overexpose than underexpose, because it’s easier to retrieve shadow details than highlights details when you fix the image (if you shoot RAW).
  • Our eyes are so sensitive that if you have any bright white elements (dialog boxes, menu bars, etc.) open in the window while trying to evaluate an image’s color, your eyes might mislead you because they will have already adjusted to those bright white elements.
