I recommend you generate a set of custom profiles, one for each of your Adobe profiles (Adobe Standard, Camera Standard, Camera Neutral, etc). They vary among themselves and they vary by camera. Inside the base profile is a base tone curve, and those base tone curves vary quite a bit. Don't use one of your own profiles as the base for a new profile. You should use one of the Adobe profiles as the base. So maybe not worth the effort.Īnother important thing to consider is the "Base Profile" you use when you run the DNG profile editor. That profile is probably 90% as good as a true dual illuminant profile made from two shots. In fact, that's the default in the DNG Profile Editor. You can make a dual illuminant profile from a single shot of the color checker. Use these to make a dual illuminant profile and go with it for all shots. So shoot you color checker twice, once at as close to 6500K as you can get and once at close to 2850K. So I'd say no, it's not worth the effort. In my experience, a good dual illuminant profile is 98% as good at multiple temps as any single illuminant profile for any one specific temp. The question is 'how much better" and is it worth the effort. The purists and perfectionists will say it is better to make and use a separate single illuminate profile for each and every color temp you may encounter when shooting. ACR will interpolate between the two different white balance values when it applies the profile. So, if the color checker image used to make the profile shows a WB of 5800/4 when you look at it in ACR, but the image being processed shows a WB of 6500, use the 6500. They are only for use when making a modified "special purpose" profile.īut to try to answer, when you apply your profile in ACR you should set the white balance in ACR to the WB of the acutal shot, NOT the white balance of the color checker image used to make the profile. There is a temp/tint adjustment under the Color Matrices tab of the DNG profile editor, but those values will always be set at zero when your create a profile. I'm a little confused by your question when you say "the colour temp / tint values given by the DNG Profile Editor." Adobe Camera Raw shows white balance in terms of temperature and tint, but the DNG Profile editor does not.
