![]() ![]() ![]() ![]() The processing pipeline is defined completely within the software and only in the software. There is no way via the EXIF tags to force a software to process an image in a predefined specific manner. Quote from EckyH on August 26, 2022, 7:13 pmĮXIF tags are just information. My first attempts to manipulate these values in the DNG file seemed to be successful, but darktable still treats that file with demosaicing. Today I found the code which checks some EXIF tags from the IFD1 part in the DNG file. Quote from EckyH on August 21, 2022, 7:06 pmĮxiftool has some limitations when it comes to change or delete some special EXIF tags so the reverse engineering approach seems to be a dead end at the moment.Ĭurrent state of the investigation: After reading through the DNG specification, I'm now digging through the source code of darktable. The good news are: I'm down to seven EXIF tags which might have an impact on the behaviour of the processing tools and I could enlist two supporters for the test images. What if not the value of a specific EXIF tag is the decisive thing, but the absence of a specific tag? In the "store new preset" dialogue window activate the checkbox "auto apply this preset to matching images" and in the "model" text box replace the "%" with the camera model as is it detected in the "image information" module - in our cases "K-5 II".īut that still doesn't provide the answer to the whether there is a general way to provide a set of EXIF tags to "force" the image processing tools to treat the images as monochrome.Įdit: Last night I had a thought. To avoid debayering automatically it is sufficient to create a preset in the "demosaic" module where the "demosaicing method" is set to "passthrough (monochrome)". *facepalm*Īt least for darktable it is sufficient to set the "Custom Image Style" with the four-way controller to "Monochrome". Sometimes the reality is much simpler than anticipated. Quote from EckyH on August 19, 2022, 7:02 pm ![]()
