How to get correct colours (with ColorChecker)?
Hi,
sometimes I have to reproduce paintings and I am looking for a way to get correct colours. I have the x-rite ColorChecker but I find no procedure to get a profile (ICC?) for C1. With Lightroom that looks to be so simple.
Has anybody tipps?
C1 7 pro, Win7, Nikon and Sony
thanks

If I remember correctly the Color Checker correction file is a DNG file and not an ICC file. I know they would not work with Capture One 6 Pro but I've not tried them with CO 7 Pro. I tried them with Lightroom and they do a good job but I don't like Lightroom so I haven't made any correction files for sometime.
I do find the color chart can be useful for WB correction by including it in a test shot.0 -
I also do not like learning Lightroom.
So is anybody here who processes products shoots with C1. What do they do to get as good as correct colors?
To get a good WB is not all. How to set a camera profil with good colors? - LCC is excellent for lenses, and so I miss a "Camera Color Correction" for cameras...

CC is universal target but you need appl. which can read and calculate color shift and export it as *.ICC PROFILES which than can be used in C1 as camera profiles.
Which application use to produce .ICC profiles is hard to find , there is "PictoColor" Photoshop plug in which can do this but results are not even close to .dng profiles Lightroom or...
If RAW converter cannot make profiles inside itself like Lightroom .dng or Photo Ninja also produce color profiles from CC target but with extension which can be use just inside Ninja itself ,you need to buy some expensive color management tool like X-Rite or Datacolor kits and I mean hardware with software for calibration from camera to printer to produce high quality ICC profiles , mean that freedom to control color in high quality manner but quick , flexible and easy cost a lot of money.
Color Munki-photo ,not sure for exact name , from X-Rite(I think) is most cheap tool-not only display version.
I hope this help , also is sad reality .0 -
I've found on some blog such method of using Color Checker:
1. Open image with CC on it in C1P.
2. Use "A" button to auto-adjust image settings.
3. Copy settings and use them with other images.
Other options were discussed here

Unfortunately, all this does is correct exposure and white point across the color checker. It’s certainly a handy way to get a base target for these automatic adjustments, but it doesn’t alter the colour values at all. IIRC the author realised this, too, and wrote about it in the comments.
The only way to use a colour target for colour correction in Capture One is to employ third-party ICC/ICM profile software. This either comes for free (ArgyllCMS for example) or turns out to be more or less expensive (basICColor input, ~300 Euro without and ~700 Euro with a target comes to mind).
Some caveats:
1. When generating a simple ICM/ICC profile using such profile software, the profile usually is usable only for THIS specific lighting situation. Even adjusting the white point may produce … interesting results.
2. The more colour patches your target has, the more universally acceptable the ICC/ICM profile will turn out to be. ColorChecker Classic is not really versatile enough, better targets start at about 300 Euro a pop.
3. ICC/ICM profiles aren’t comparable to DNG profiles as produced by ColorChecker Passport for Lightroom / ACR. Multi-target profiles are possible (I guess that’s what Phase One does when producing their own profiles) but setting up a proper profiling situation for it to work sort-of universally is not too feasible in the field.
4. Homebrew ICC/ICM profiles work pretty well in a controlled-lighting studio environment. In a more versatile context, though, I guess it’s easier on both time and money to leave it to Phase One doing all that profile mangling.
5. To tame “hot†colours, I found CO’s Color Editor quicker and easier.
Best,

Thank you first at once, special to Marcin_ for the link. Here I will search more, also with the "A" button. - Can this button recognise the colors out of a ColorChecker table?
My dream is a procedure analog to the lens cast correction: I take a picture of the ColorChecker at the specific lightning situation. This is than the basis first for setting the correct White Balance and after that second for correcting the "Color Balance".
A other way could be: C1 gives me several film curves for several camera models. Why not also a film curve "correct colors" for every camera model?
Could be that anybody from the C1-team read that?

Or maybe the camera manufacturers could do this?
Or perhaps the lighting companies that supply the lights you use to obtain a consistent light?
There are so many variables in the steps along the path that it seems it is not really clear where the best source af colour matching might be.

Hi Gust,
I use colorchecker 24 color and create a profile ICC with Profilemaker5, wich can be use with C1.
For be best characterization of the camera, better to use the colorchecker SG 140 color... (very expensive)
But don't need to do it for each shooting, the characterization of the camera, can be do one time, under the light flash studio than you use often for your work. In studio, better to shoot in degree kelvin in the camera setting.
And surprise, this profile ICC did in studio, work well for shoot ouside.
But ofcourse, all this have a cost...0 -
Hi everyone,
I'm just found one less expensive appl. for generating *.ICC profiles from CC(and IT8 , CCSG...) target few days ago
so you can try it before buy -"Profile Mechanic-Scanner v1.0" from "Digital Light&Color" site-69$ i think.
But ICC profiles (cameras,scanners) do not work easy and as expected in C1 or else.
There are lot of factors(color working spaces,output spaces...) which do not allow easy and high quality work this way.
By my experience if apll. have no ability to use this targets incorporated in them workflow (there are many problems with different gamma curves ...and so on) it's much better to stay with available tools inside specific apll. itself,shoot with
best available custom WBalance in camera to get best starting RAW file color balance(optimal use of all three channels-sensor pixels) and use tools inside.
Actually you can use RAW image of Color Checker and adjusting color from patches in "Color Editor" until you get exact values as should be(exact values for every color are available from many sites related to color management issues ) and save it as preset in color editor ACTUALLY YOU CAN SAVE IT AS *.ICC PROFILE and use it for input profile of specific camera.
So , there is actually way to produce camera ICC profiles from inside Capture One for use in C1
Hope this will help to clear the issue about profiling in C1(this can be seen in tutorials also)..D0
