Tested and it works. I am just wondering if the color rendition of the IQ250 and the Fuji GFX50s are so close that the colors are matching. I made the experience that the C1 DNGs of the GFX are much more saturated and with higher contrast. As this is a usual behavior if comparing C1 with Lightroom, I wonder how much the difference really is.
If someone is interested I could do a GFX Profile for C1 with basiccolor Input, but I have to check with basiccolor first if I am allowed to distribute it.
So would somebody be interested?
