I'm the someone else. LOL
Sue, I was looking at Carole's pix here, Show Your Atmospheres, as an example of something which "worked" with her particular camera, in her particular lighting setup. I want her to be able to show off mibs like her "interesting little pelt" to their best advantage.
So, that's why she used the darker cloth, and it happened to be purple.
Carole, it sounds to me like Sue agrees that the pix are getting good!
And dark seems to be the right idea. AND purple worked well here, but if you take a picture of your new cubscout shooter, dark gray will probably go better with the colors than purple. For example.
Do I have this right, guys?!
