I made my own Capture One (v9) A7RII profile with DCamprof. The profile was made out of a shot with a CC24 in high noon sunlight (5000k).

Some people were interested in charts shot at ISO 50 with the A7rII, here a CCSG and IT8.7 :

https://www.dropbox.com/s/qitmp7aanzg72us/FH-A7_charts_ISO50.zip?dl=1

Shot with strobes around 5000K (.sp files included for each) + flat field pic. The folder includes the capture one v9 settings too.
CCSG is post Nov 2014, IT8 is from W. Faust (charge R131007).

Since I don't use my A7rII much, I have not bothered to create some ICC profiles yet.

Hello there. Just registered and this is my first post. I know this is an old thread and all, but I just wanted to thank Torger for his works on the profiles made available here.

I have taken a picture of a flower and I can't seem to get a decent camera profile that doesn't make it's colors "electric".
Also, I can't ever seem to find Lightroom's skies rendered better then CaptureOne, and that's with C1's default color profile.

Don't really know about skin tones, but I have a question: is there any one single profile that looks good for every kind of photography ( considering same illuminant)?
Landscape, macro, portrait etc, supposing same weather conditions - is it too much to expect that I can use only one profile for it all and it will always looks awesome?

Anyway, here's a link to the original compressed RAW file of the flower and it's in-camera generated JPEG.

https://www.dropbox.com/sh/jaec602w6kavg7a/AADtVy2UsLx-L3DaaOhktDLfa?dl=0

The Adobe "standard" profile does the best job at keeping the colors "natural", but they kinda lack some vibrance and always look kinda plain. But it's not really linear, if I crank the vibrance slider up, some colors look too vibrant (can't recall which ones right now, camera is new and I haven't taken too many decent pictures with it worth peeping to much).

Still, the in-camera JPEG is close enough to what I recall from the scene, but still a bit electric too. And I just love shooting RAW for a variety of reasons.

Also, C1's color renderings almost always look better then Lightrooms, as I said. The problem is: I think the software itself is too cumbersome and Lightroom is A LOT more practical to work with.


BTW: These verification steps are a PITA.

Do you have any target that includes colorchecker patches? IF you do, could you take a picture on a midday that would include the target, skies (the light cyan to deep purplish gradient in case a clear sky would be great) and the subject in question (flower).
The common problem is the saturation vs lightness compromise. You either have the right saturation, but the most of the photo is dull, or you have popping picture with light bright cartoonish colors.

Nope, unfortunatelly I don't have a colorchecker. I'm thinking about buying one. Is the X-Rite Passport good enough? Is there any one better?

Would that problem be solved with some wide gamut monitor? Isn't it possible to dull down the extra-vibrant colors to "compress" it to an sRGB monitor and all look nice and natural?

you can experiment with the following raw cgats files (see .ti3 attached) - those files work both for dcamprof command line (free) and LPrD GUI (commercial) - they shall work for both ACR/LR dual illuminant and C1 single illuminant profiles building :

depends on the flower - if the color is saturated then Passport is not the one (but it is a good target in terms how patches are made) , but then - are you trying to do repro or just kick the colors ? if latter then why not in postprocessing - there are tools/plugins like http://www.uni-vologda.ac.ru/~c3c/plug-ins/colorwizardbasic.htm or https://www.3dlutcreator.com/ or http://nuclearlight.net/firegrade.html or http://curvemeister.com or whatever... even a naked PS can do

PS: and for certain colors you might run into issues how decent camera's sensor CFA spectral sensitivity will handle those

while trying to repeat somebody converting in one converter in a different one is a very ungrateful thing - here is a simple pure matrix profile built with above mentioned raw cgats in ACR vs posted C1 conversion... not 100.00000% but

All three ARWs were opened with a custom profile in C1 then I adjusted the exposure slider to avoid clipping in critical areas. Nothing more. The profile was made with Lumariver and is made for a linear curve use. In general I can recommend to use linear curve in C1.
Does this looks better to you?

Edit: As the colors in the first one looks too blue I've added a processed-to-my-taste version (whitebalance set to daylight + some contrast with curve/contrast/brightness/vignetting).
