Today, being a Bank Holiday, means that I have a few hours free in-between my household and gardening chores, and looking after my wife, who is struggling with crutches at the moment :-(
Plenty of time to experiment with my new A3 LED lightbox :-)
The technique I've been trying, is to capture a high key bracket set and post process as layers in Photoshop: no HDR tone mapping here!
Once in Photoshop, it is a simple matter to explore different 'looks'.
For example, in the first image below I went for a basic high key look; whilst in the second image I carried out some inversion and channel swapping.
Two different images: but both created from the same capture data.
...and finally: this interpretation.
