Marquinius Posted November 17, 2007 Share #1 Posted November 17, 2007 Advertisement (gone after registration) I've been looking through some threads, but cannot find anything on this phenomenon. If somebody can point me to the right thread, that's an answer as well! First: I never shoot "in camera B&W", but I'm always trying to figure out what's happening anyway. As it is lousy weather, I have some time to tinker .. I got curious, because in a blog somebody stated that when you shoot in B&W although you see the preview in B&W, the DNG is still in color. That figures. But it could help me visualize B&W while shooting, without the actual colordata getting lost. So far, so good. So I took two shots, one color and one B&W, both DNG+jpg-basic, auto white balance, same light, same spot, five seconds apart. The jpg's were OK as in "1 color, 1 B&W". (I only use them so I can check if my P-5000 actually downloaded them from my SD-card), but the DNG's were different. The one shot "in color" was very warm, while the one that was "behind" the B&W was cooler. The last one checked best with what I was seeing at that moment. I'll have to do this again with a fixed white balance, as I'm aware that auto WB can really jump from high to low. But still: anybody noticed this or have thoughts on it? Is it still the same auto WB doing its tricks, or does the DNG really differ because of some in camera thing? Link to post Share on other sites More sharing options...

guywalder Posted November 17, 2007 Share #2 Posted November 17, 2007 sounds like the standard AWB performance, nothing to do with B&W Link to post Share on other sites More sharing options...
chris_livsey Posted November 17, 2007 Share #3 Posted November 17, 2007 If you "corrected" both DNGs to the same WBalance they were then the same ? The wacky Auto balance is only an issue in jpeg especially as you can batch change in C1 and I think this is unrelated to B/W although I wonder if the setting affects the embedded DNG Jpeg (ie is this B/W or still colour and displayed as B/W) ?

Marquinius Posted November 17, 2007 Author Share #4 Posted November 17, 2007 I never really looked at the Jpgs (who cares about them anyway). Basically the question is: does it affect the DNG? I'll see what happens when I use anything else than auto WB. Link to post Share on other sites More sharing options...
aim8 Posted November 17, 2007 Share #5 Posted November 17, 2007 From time to time, I shoot in B&W mode with my M8. Today, I also figured out that these B&W DNG pictures came up in colour using Capture One LE. However the DNG thumbs looked B&W on the desk of my PowerBook running MacOS10.4. Indeed there is a difference between the true and "false-B&W" color pictures. Do you have any solution to opened directly in B&W the DNG pictures shoted in B&W mode ? Does the problem come from any settings to be corrected in the system or in Capture One ? Thanks for your help Link to post Share on other sites More sharing options...
