Tungsten Studio Light

[rrosener@xxxxxxxxxx (Russell Rosener)]

Last week I shot two rolls of Konica IR under tungsten studio lights. I
used a #25 Wratten for filtration and used a Gossen Luna Pro F rated at ISO
40.

Evidently the film picks up a lot of speed under tungsten light! Even
though I bracketed a full stop on either side of the meter reading the film
was very overexposed. Develpoing was in Rodinal 1:25 dilution for 9
minutes. I plan to process the second roll for 5 minutes in the same
developer, and reduce the previous roll in Farmer's Reducer.

Judged on what I've seen under the same studio lights I could probably rate
the film at ISO 160 next time, and process for nine minutes in the Rodinal.
