Worked out Trip Report — Looke like I have over $66 coming!
WIW in to see if I wanted a report listed in the weekly reports available listing from Air Inq. Svcs. I spoke of the 3-floor arrangement and the Viscomat development, which look good. He agreed that careful considerations should be given to problems of obsolescence. He spoke at the possibility of getting a consultant — Ben Diver, who is retiring from the RCE Photo Lab supervisor’s job on 01 Jan., might be available.
Spent the afternoon w/ Paul Gaudette and his cronies on the DPC Bldg. layout and spec. preliminary detail.

Called Dr. Edgerton at MIT re: my flash gun. It is rated at 40 watt-seconds. The candle-power/watt is 3-to-4 — 120-160; multiplying by 10 for the reflector factor — 1200-1600. The guide Nr. is then found by using the equation GN = (1200 x ASA/15-25) to the one-half power.
Discussed the street situation with Chaz Barringer, who had been in contact w/ Mr. Hussey; the article re: the streets was taken off the agenda so that it was not voted on.
Worked a little on the calculation of guide numbers; I’ll work out those for the films I use checking with those on the flash reflector. I can evaluate the constant this way.
