There is a difference in contrast when taking pictures under daylight (shade) and indoor tungsten roomlight. When I shoot a roll of BW film under both conditions inevitably this manifests.
Why? I think that it has to do with the bluishness imposing a very slight fog veil over the outdoor image. Even looking at something under the shade, and then immediately placing a K2 (yellow-green) filter over your eye to judge the same scene, shows a slight increase in contrast when using the filter.
I took photos of a gray scale with color patches under both conditions at the proper exposure. Obviously, the colors imparted somewhat greater contrast with the K2 but the gray scale ALSO did the same. The difference was not much but was at lease half a paper grade.
I prefer the lower Kelvin temp for more accurate tonal rendition. Photos taken under tungsten lighting really seem to differentiate the tones well and are easier to print. Are my assessments about this accurate? - David Lyga
