Color profiles-rgb values
Hi,
I am a museum professional in the US, and we have to stick to set federal guidelines for cultural heritage imaging, but I am running into an issue with the white balancing- I have to have color targets in all of the photos, and I must select the second gray patch from the white, and the value of that patch must be 200 +/- 5 rgb, which is a preferred standard set by AIC (American Institute of Conservation) who regularly image 3d objects like me. However, in their reference book, they use photoshop to check their rbg value for the white balance- and I have been opening photoshop with the 'open with' with capture one but the adobe 1998 rgb values are different in both softwares on the same gray patch even if I change the color profile to match each other. Maybe this is too complicated, but are they not reading the same because they are different softwares?

If you 'open with' an image in PS from capture one then the same thing happens as if you opened the file directly with PS.
Assuming you are talking about a raw file (are you?), Adobe Camera Raw will open and let you develop the raw. And of course the result will be different in PS as they are two different applications and you're settings (or defaults) are different and the raw interpretation as well.
In C1, set the soft-proof to AdobeRGB, set a color readout on that patch to "show always", set the exposure and tones using the exposure and level tools, maybe HDR tool, then use the WB picker on that patch, re-adjust your set tools if needed so that you have a decent image regarding tonality and colors within boundaries without too much clipping (highlights/shadow warnings).
Then, "EDIT with" Photoshop from C1, which creates a TIFF 16bit, AdobeRGB, if you choose these settings (which you should).
If you are not working with raw files then avoid C1, there is no point in using it.

Did you figure it out?

Hello BeO,
Yes, this helped a great deal (now I just need to figure out why I am getting low rgb values on the gray patch for each photo I take)

Can you paste a screenshot of the histogram here, of such a photo? And paste a screenshot of the tools you use in C1 to adjust your raw files, e.g. exposure and levels?
