Thanks for the idea, I might try that. The major problem is that dags are UV
sensitive only. So it's not just about the ISO, it is also about getting the
UV at about f45. For example the successful plates that I have done in
camera with the Becquerel process have been f5.6 in full noon bay area
sunlight for 15 - 30 minutes. Now increase that to f45. Don't think it's
possible in studio even with large amounts of time and photofloods.

If the ISO is about 1 and you are using strobes, you can always use multiple
bursts. Maybe you could try 50 flash exposures for each plate. Or maybe it
is enough with only 25. And you can work during the day or night.
