schwarz und weiss Posted February 15, 2009 Share #1 Posted February 15, 2009 Advertisement (gone after registration) Hi I took some Raw + Dynamic B & W jpegs yesterday, and the white balance/tint as interpreted by both Capture On and Lightroom, was way off. The white balance was much too high (eg 8500), and the tint was very negative (-25), which gave a strong green cast. The jpegs were fine, though. The white balance was set to AWB. The raw files (without jpegs) that I'd taken previously were OK. Is this a problem with using raw + dynamic b + w? Any ideas? Thanks, Richard Link to post Share on other sites More sharing options...

Richard D Posted February 15, 2009 Share #2 Posted February 15, 2009 This has been discussed on this forum a few times; it is not a peculiarity of your particular camera. My understanding (someone will correct me if wrong) is that one of the reasons 'dynamic b&w' is so..... dynamic, is that it introduces the equivalent of a green filter. Easily removed from the RAW image by any capture software. I must say it surprised the hell outa me the first time I saw it.....:-) Link to post Share on other sites More sharing options...
schwarz und weiss Posted February 15, 2009 Author Share #3 Posted February 15, 2009 Ah... Thanks - that makes sense (sort of!). So the raw isn't direct from the sensor - it's taken after the filter has been applied. Richard Link to post Share on other sites More sharing options...
artivisual Posted February 16, 2009 Share #4 Posted February 16, 2009 Can you please tell me how you remove it using Aperture or ACR? Thanks in advance. Link to post Share on other sites More sharing options...
Richard D Posted February 16, 2009 Share #5 Posted February 16, 2009 Can you please tell me how you remove it using Aperture or ACR? Thanks in advance. Since I don't use either program, I was hoping some good samaritan would be here to help. In both those programs, you must have white balance adjustments. Try auto (probably works fine), or sunny, cloudy, tungsten, etc. Or use the 'tint' slider to remove the green. Hope this helps, at least a tiny bit. BTW, the camera came with it, why not just use CaptureOne? Link to post Share on other sites More sharing options...
schwarz und weiss Posted February 18, 2009 Author Share #6 Posted February 18, 2009 Hi. Sorry - been away. In Aperture, you can use the WB picker to select a neutral grey (if you've got one), or just drag the slider. I've always set WB to what looks right, but its normally around 5000K. The tint will also be corrected if you use the WB picker, otherwise it is typically about 0, maybe slightly negative. In Lightroom, the same applies.

Ed_K Posted February 19, 2009 Share #7 Posted February 19, 2009 Advertisement (gone after registration) uh Richard, since you mentioned the use of Aperture, did you import the .rwl file to Capture one first and save it as a DNG before editing it in Aperture? because i was still waiting for Aperture to support the .rwl file from D-Lux4, btw thanks for sharing.

schwarz und weiss Posted February 19, 2009 Author Share #8 Posted February 19, 2009 No, I normally use Aperture, as I don't want to create Tiffs or jpegs, so I downloaded the Lightroom trial for these rwl files. Hopefully Aperture support will arrive before the end of the trial, as Lightroom's upgrade price is a rip-off! Richard Link to post Share on other sites More sharing options...
donmcmahan Posted February 20, 2009 Share #9 Posted February 20, 2009 the heavy green cast is of course rather frightening at first but it is there for a purpose, i would have to ask why you are shooting raw+jpeg in dynamic B&W? i have been shooting this way recently as an experiment as i normally just shoot raw and convert to b&w in post processing, but i wanted to compare in camera b&w jpegs to my own b&w raw conversions. i am not sold on dynamic b&w jpegs, i will probably keep shooting raw but i have learned a new trick to use in my conversions, i never would have thought of drastically altering the white balance before converting to b&w....by the way to fix the white balance in ACR either use the white balance picker eye dropper tool and sample a neutral or use one of the presets daylight, cloudy, auto or which ever gives the results you like. but before you do if you are converting to b&w just try leaving it alone and hit that greyscale button in ACR and see what you think.

schwarz und weiss Posted February 20, 2009 Author Share #10 Posted February 20, 2009 Well, for me it was just an experiment, and if I didn't like the jpegs then I knew the raw would still be available. I'd only had the camera 3 days! Richard Link to post Share on other sites More sharing options...
