More ramblings...
White balance:
These backs have different white points (not sure if that is the correct use of the term, but oh well). For the image above, CC20 (second gray from the left):
TC: White balanced to 6574/3.9 (OOC= 4845/-3)
3100: White balanced to 6803/17.7 (OOC=5049/-0.1)
I struggle with white balance in Capture One. It is a more iterative process than LR. To me, LR really is blue/yellow in temp and magenta/green in tint. In C1, moving temp affects the magenta/green cast, so there is more back and forth.
Point is, I liked the TC's OOC “white point” better than my 3100. A least with gray overcast skies. Getting to a “pleasing” white balance was faster on the TC. Obviously, for the images above it was just a click. But I prefer things not that warm because shadows need a little blue in them. For example, I would lower the temp in the images above by about 800. In the TC image below I posted in the other thread, it took just took a few clicks. I still do not have the 3100 version where I want it.
As for "accurate" color, I am very afraid to go down that rat hole. I do not have the skills or the equipment. The point of me going through this exercise has nothing to do with accurate color. It is purely to see if I "like" this back's color significantly better than the 3100 (well, that and bland curiosity). Viewed alone, any one of these renderings would look fine. I will say this: of the four options (TC and the 3100 with three different profiles), I like the TC best. There is a lot I do not understand, however:
- The orange looks far better in the TC image than any others. All the 3100 versions appear too saturated; the orange gets "crunchy." P1 Outdoor DL profile is second-best for the orange. This is curious because the difference between yellow and orange-yellow (colorchecker squares CC16 vs CC12) is too muted on the TC. They almost blend together. In real life CC16 and CC12 look much more like what is displayed with the Lumariver profile.
- On the other hand, I still think reds are too punchy in all but the Lumariver profile (which frankly is too dull). The apple looks "right" in the Lumariver profile.
- Others in previous threads both here and on lula focused on the greens. Sure enough, the limes and foilage go yellow on the 3100. From yellowish green to blueish green: 3100-Leaf, 3100-P1OutdoorDL, 3100-Lumariver, TC. This is all with a neutral CC20, 201/201/201.
I lowered the exposure to match the published luminance value of the colorchecker square CC20 (=200)

Of course, none of the readouts for the color squares are anywhere close to what they are supposed to be!
:loco:
Here are some revised color readouts for the orange. TC top, 3100-Lumariver profile bottom:
Tomorrow I will try to do some shifting with the 35 and 40 for you all.
