DNG Profile Editor - "Unable to check white balance using gray patches"

[edo moon]

Hi - was having trouble creating a profile for my new camera for Lightroom, (using x-rite, saving as DNG etc.) and kept on getting the above edit when using DNG Profile Editor.  I finally shot the x-rite color checker real tight, which essentially gave me a darker exposure, and that was accepted.

Remember that you have to close Lightroom for it to take effect.  Martin Evening details the process in his Lightroom CC/Lightroom 6 book, pp. 274-277. 

I've used specific camera profiles (one for sun, another for shade) for the past 8 years or so - I find a subtlety that none of the canned profiles have, though Adobe Standard is useful also.

Just an FYI.  Good luck!

You normally don't need that. That's just a shift in white balance, all covered by a single dual-illuminant profile.

What you need dedicated profiles for, are light sources with irregular/spiky/uneven spectral distribution. Fluorescent tubes and LED fall into this category. They have spectral curves with sharp spikes and deep valleys, not a regular, even curve like natural light, incandescent or flash.

A possible exception is if you have strong, single colors affecting the light, like a strongly colored wall reflecting into the scene, forest interiors with sunlight filtered through green foliage, and so on.
