Hello,
I have been writing my own DNG headers to raw sensor grabs successfully for a while now. These have all been CFA sensors but now I have a monochrome sensor in the mix and I would like to save these as DNG as well. I have tried a variety of settings with the PhotometricInterpretation, CFAPattern, CFARepeatPatternDim tags and have had no success. Excluding the latter two tags will produce a greyscale image with dcraw but photoshop will not open these DNGs. I could just save these images as PNG but everything else is DNG and it just looks nice when everything is the same.
Any ideas on header tags for a monochrome DNG?
Thanks!
