Unusual Long Exposure Firework Photographs by David Johnson
The technique I used was a simple refocus during the long exposure. Each shot was about a second long, sometimes two. I’d start out of focus, and when I heard the explosion I would quickly refocus, so the little stems on these deep sea creature lookalikes would grow into a fine point. The shapes are quite bizarre, some of them I was pleasantly surprised with.
I am no uber-meister of thermodynamics either. That PhD thing I got helps, but I too have to go back, re-read the basics and then build up to the relevant literature on the subject I am studying. (This is true of all scientific work; you are always reviewing the basics.)
Oh so true. It’s one reason I spend time on the forms at this blog’s host, Science Forums (dot NET) — answering questions forces me to review basics that might have atrophied. It’s a constant battle.
Anyhow, I did (and continue to do) a lot of re-reading of my favorite thermo texts
I understand the individual words in “favorite thermo texts”, but taken together it makes no sense to me. Thermo being one of my least favorite parts of physics and all that.
