While perusing an old photography magazine on Archive.org I found an early predecessor to the Sunny 16 rule we use today. The magazine was published in the Summer of 1937. We can learn a lot about photography from looking at this table. For one many of the shutter speeds will look somewhat different than we are used to. Modern shutters use fractions like this: 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2. If you picked up a camera of this era, for one, the shortest speed: 1/1000'th would have been a fancy camera. Many cameras of the era maxed out at 1/300, or 1/400. Most cameras also used a slightly different scale too: instead of the more modern 1/4 they veered to 1/5 and went up from there to 1/10, 1/25, 1/50, 1/100, 1/200, 1/400. Another thing to note (go to the original magazine article, link supplied) and you will see a wide variety of films. None of the films listed exist today. Most of the companies are now only footnotes in photographic history. And

Just wanted to let you all know of a fun resource for creative stuff including photo related items..... In Oakland there's a place called the  East Bay Depot for Creative Reuse . There's usually a little bit of photo related sludge in a designated area, but also interspersed throughout the jumbles of  junk   treasures. On my last visit I picked up: a mostly full case (500x) of those  old airmail envelopes   a few dozen sheets of  letraset a bunch of 35mm and 4x5 negative sleeves (ca. 50-100) various laser labels a seemingly unused cable release (for conventional film cameras) a couple of old maps a roll of old Kodachrome (I know I can't develop it!)  multi-colored sheet feed paper for impact printer (dot matrix) and some other miscellany.  Box of Misc Crap in the "Camera Corner" (not really in a corner, and not all cameras) In the end it  all fit in a medium size moving box and cost about $28 out the door. There were a few 35mm SLRs

AGFA - Gevaert Film Data Sheet (ca. 1960's?) I'm ashamed to admit some details of where this data sheet came from. I think it might have been in a pile of old sheet films my uncle Erik gave me 15 years or so ago. Sad thing is, since I could get modern films easily and relatively inexpensively, I think I ended up tossing out the films. I'm such an idiot! What this may be useful for is anybody who finds any of the following films in a freezer somewhere: Agfa Gevaert IP15, IP 21, IC 22, IP 24, IP 27, or IP R. The data sheet has development times for then popular developers such as Atomal, Refinal, Rodinal, Perufin S. Atomal and Rodinal are still around, I don't know anything about Perufin S, and Refinal sounds familiar. Happy developing!
