Varying Lighting Conditions

2006-04-13 by hanson102

i believe that a lot of us work with our images in varying lighting
conditions in one specific area.  i myself work in my room where
ambient light changes from morning 'til night.

in such conditions, should i calibrate my monitor on each condition
and use the profile as my ambient light change?

this is so far what i have done,
a. calibrate morning
b. calibrate afternoon
c. calibrate evening with room lights on
d. calibrate evening with room lights off

i have 4 different monitor profiles and i use each according to the
lighting condition i am working in.

is this a correct way of working on varying lighting conditions?

thanks!

regards,
david

The right answer (and the one that many users resist hearing) is that your conditions should to be stable, consistant, and controlled, with no variable natural light. Short of that (and many users insista on falling short of that), you need to be sure that you are using the same HARDWARE settings for each profile you use, or any but the last one built will be invalid. The key to this all would be to build one profile at each of the applicable light levels in Spyder2PRO v2.2, so that you would get appropriate monitor luminance, gamma, and whitepoint for each set of conditions. Then change between them as needed. Given that anything above a moderate light level is simply unacceptable for serious color work, this would mean, at most, three profiles at three sets of target values. We will have more features to assist you with this in future versions.

What you DON'T want is some scheme where the gamma of your screen is hopping around as your sleeve shades the sensor... thats no a reasonable solution for serious color work.
