Mina at 7200Ws
Iodine: 50 seconds
Bromine: 12 seconds
Second Iodine: 20 seconds
Exposure: 7200Ws @ f2.8
Lighting: studio strobe, one head, 22" beauty dish reflector
Development: 2:15 @ 80˚C
My first attempt at using studio strobes with daguerreotypes. I wrote this elsewhere:
My daughter agreed to sit, although complained about the flash afterward. To make up for it, I allowed her to push the button while I sat in the chair. It wasn't as bad as the descriptions I have heard of Jerry Spagnoli's set-up--burned hair and all of that--but it does make a very loud POP and you see spots for a minute or so. Anyhow, as you can see, the image is present, although this is a rather ugly example.
Anyhow, I used a Speedotron 105 "Quad" four-cable head in a 22" "Beauty Dish" reflector at 7200 watt seconds (with 4803 and 2401 boxes). The rim of the reflector was about 32" from subject, and was placed above and to the right of the camera.
