Interesting. I don’t know why this is doing what it is doing. It’s a trial of eleven stacked exposures while I sign something. Full colour but cold white light on a black t-shirt with a black background. There’s a small amount of blue and green in the shirt, but I don’t think that accounts for the interesting colour blooming on the composited image. It’s not working as a strategy for capturing the 3D shape the sign makes in space, which was the motivation for this, but it’s something to bear in mind and experiment with more in future….
It seems to be movement. A composite of images of me sitting still didn’t do it.
Hmm.
