I am not taking any additional step in LRC for WB - should I? Then shoot the 24 color panel which I am attempting to use for profile creation in LRC. The first picture I capture at the start of the shoot is the light gray panel in the ColorChecker Passport 2 while creating a "Custom WB" in the camera. Since I am shooting artwork, the pro from X-Rite recommended I shoot the Passport before each shoot in order to calibrate the colors specifically for the day's lighting conditions - the profile for that day, for example, would be an image of the 24 color square panel, processed and saved as "ArtShoot_Date_RobertsArt", then applied to all those images. I learned this from the photographer who recommended the DP2 Merrill for my purposes - shooting stills of artworks for print reproduction, archiving and multiple online uses. x3f files, then something is amiss with the Import that needs correcting!! Then to create a profile you 'Export' the DNG by selecting Preset in the Export dialog. Or you can photograph the Color-Checker and Import direct from the camera using the option in the Import dialog. x3f photo of the xRite Color-checker in Lightroom-Classic, you can convert it to DNG from the Menu. You should not need a response from xRite. trying to get response from x-rite about this. However a shot of the Color-Checker at each shoot is useful to easily correct White Balance. I do not expect my camera's sensor will change dramatically between shoots (requiring a profile for every shoot). I create one profile for my Nikon D750 from the xRite color-checker, and that is the profile I use always. "each shoot"- now you are getting really particular. It requires a Lightroom plug-in to create a profile for the camera specific to each shoot, Yes- heard of it - I have it, and use it also. However, I am also using the x-rite i1 ColorChecker Passport Photo 2 in order to create color profiles for each shoot. * And if you cannot import- there is some other problem that you need to explain. Using the Photo Pro software for a TIF is not needed. TBMK - Not true! As in my post above the Sigma DP2 Merril has been supported by Lightroom versions for several years.(the camera is from 2012) x3f file created by the DP2 Merrill must be run through Sigma Photo Pro, and export as a TIFF or JPG. I am using Lightroom via Creative Cloud subscription and always update, now at 9.2.1 release.
