I 'dual-wield' a pair of Z's when I shoot weddings. My original Nikon Z6 and a Z6ii . Sync the times together, integrate all the images from both cameras and edit the complete set in Lightroom balancing the colouring etc for a uniform look. I apply a preset on import to Lightroom as I always have, as a starting point, before stepping through every image one by one to be checked/corrected before the final output.
On my previous setup, two D810's the identical cameras, (regardless of the brand of lens used) would have the same colour cast, applying a preset would give the same results to photos taken in the same lighting. But with the Z6 and Z6ii being different models, the colour between the two is hugely different. mostly it's the Tint of the images - one camera's images would be extremely magenta, and if I made a specific preset to counteract, I'd make the other camera's images too green! SO I have attempted to make two presets, and I filter the results in Lightroom's Library tab and apply a different preset to each. But I'm really struggling to get the colours correct, which feels like it adds a lot of time to the editing process.
I've gone through the menus of the cameras and checked they are both using the same colour profile, same white balance settings etc. Anything else I can do to get a clean, unaltered image from both cameras that would give the same results in the edit? I think I heard somewhere that the Z cameras apply some colour settings to the RAWs, and not just the JPGs as previous models?
