Dory Breaux DP Posted May 22, 2007 Share Posted May 22, 2007 I'm a little confused about this one. I thought that there wasnt any T/D ballancing in BW film because there isnt any color? Am I wrong? Link to comment Share on other sites More sharing options...
Premium Member Will Montgomery Posted May 22, 2007 Premium Member Share Posted May 22, 2007 Tungsten light and daylight are are different wavelengths so even black & white film reacts differently under different lighting even at the same meter reading. Obviously it doesn't effect color, but it effects contrast and exposure... that's why even black & white films have different exposures under daylight or tungsten light. I'm sure someone can explain that better. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted May 22, 2007 Premium Member Share Posted May 22, 2007 It's a b&w stock so it doesn't have a color balance - the image is monochrome afterall. But even though it is panchromatic (sensitive to all color wavelenths) it's slightly more sensitive to the blue end of the spectrum than the red end, hence why it is rated 1/3 of stop faster in 5500K light than 3200K light. Doesn't affect contrast per se, but it does allow you to use color filters to control the exposure/density of different colors, which can affect contrast -- for example, in daylight, a red filter makes blue skies darker, and shadows darker (because they have a lot of blue in them) but faces lighter (because they have red in them). So contrast is increased since now you have whiter faces against darker skies with darker shadows. Link to comment Share on other sites More sharing options...
Dory Breaux DP Posted May 22, 2007 Author Share Posted May 22, 2007 Alright thanks. I think I'm going to use 250T stock with a tungston to daylight filter and a yellow filter to get he effect I'm going for. SHould be cool. Link to comment Share on other sites More sharing options...
