When using a sheet of paper, remember that the brightest papers sometimes have a blue tint so they'll look whiter.
I think the "coffee filter trick" works better than a sheet of paper--just use a white coffee filter (or napkin), put it over the lens, set focus to manual, get a good exposure, and use that shot to do AWB. Sort of the "poor man's expodisk".
There was a question about how to tell if fluorescents or tungsten is used. Since fluorescents come in the normal bulb (edison base) format, you can't always tell by looking at them. Set your camera to flash AWB (or daylight) and take a shot. If the lights look green, gell the flash green. If the lights look orange, decide on if and how much you want to gell the flash.
IMO, mixed daylight and tungsten is ok, especially if you get the people to the correct WB (or a bit warmer than neutral). the Green from many fluorescents is horrible--I'd rather have a slight magenta cast than a bit of green. Better that your subjects look "in the pink" than "green around the gills". :-) |
