<p>Thank you, Andrew and Bill C for your suggestions. I have now bought an incident meter and made diffusion screens for the lights. This now allows me to balance the light falling on the different parts of the quilts, greatly improving the tonality and colors. Together with applying the X-rite ColorChecker profile the colors are looking quite good, i.e. the wife is happy. While I can use the AdobeRGB in-camera and also save them in that color space in Lightroom, I cannot get them printed in that color space at my custom lab as they only use sRGB in printing so I am staying with that color space in all steps.<br>
The contributions here have been very helpful and a great education for me. Thank you to all who responded!!</p>
