This pair of images consists of a light box composition on white, and its LAB L-channel inversion on black. My thoughts are turning to Photographing Flowers for Transparency, as I am teaching my techniques this coming weekend.
Incidentally, if you can’t make the workshop this weekend, we’ve listed the 2019 Photographing Flowers for Transparency workshop. It’s scheduled for the weekend of June 22-23, 2019 in Berkeley, California—and is now open for registration. Click here for more information and registration via Meetup.
