Total Photo Computer (TFC) found!

Postby Phil Winkler » May 24, 2006 9:20 am

I just found my old one which I bought from Jim Jasek back around 1973 or so. It was in a closet with some old Army stuff and is still in great shape even if a little mud stained.

I think this was discussed here a couple of times for its use in calculating multiple flash exposures in large rooms, etc. While I don't have the manual anymore I remember a complete writeup with instructions and examples in the Speleo Digest of 1970-1975 era.

The TFC is essentially a circular slide rule device 4 in in diameter. It has a table with Guide Numbers and BCPS for flash bulbs, permits you to calculate the GN based on film speed, shutter speed, etc., etc.

Anyone in Huntsville Grotto interested (keep it in the family)? If not, it goes to anyone else interested.

Phil,

You sent me one a couple of years ago. I'd like to get the other one to give to Nathan Williams in our grotto. He's our award winning photog.

I'll send you a SASE if you want.

Scott,

I seem to remember something like that, but have no idea how I ended up with another one.

It will be in the mail on Monday or so.....

I'm glad they are still of some use, too.

Cheers,
Phil Winkler
