The summer school holiday is coming to its end and time is running out before the working routine kicks back in. Maybe that's why the compulsion to work at photo editing has been so strong.
I spent most of yesterday afternoon and evening refining this technique. It arose from work I did the day before, going back to the paintings of Turner. That particular avenue led to an unsatisfying dead end. A second attempt yesterday afternoon also ended in emptiness.
In the evening, just to keep myself awake, I went back to the earlier failure and streamlined it, carefully noting what I did. This was the result, which I took heart in. Three hours work.
From there, the process got refined a little and the rest of the evening was magic.
I shoot for fun, with a Sony A7II, a Mavic Pro and my trusty iPhone 6s.
