assuming i set the preset color balance in camera to sunny day (ie similar to film), than i shoot under a artificial light with a known color temperature.
if i shoot raw, i just adjust color temperature slider to correct the color cast.
if i shoot in jpeg, adjusting color balance or channel mixer will depend on my eyes (if got color blind, how) and the correctness of the monitor calibration.
why is it like that? why jpeg cannot use color temperature slider (is it done on purpose or limitation of technology?)
also, is there a chart to say, eg, adjusting the slider of each of the color in color balance option to certain amount equals to a certain color temperature?
sorry my bad english, hope you guys can understand what i asking.
happy cny 2006.
