us with a copy of his reciprocity tables for pan films and Tmax 100. The Kodak tables are wrong.

This has been asked for in another thread, but to enable everyone to get their copy, here is a link to a page I put up on my machine.

http://68.145.119.122

They are in PDF format and represent a scan of information I was given at a Barnbaum workshop/course last July.

Just print them out, cut them out and laminate them back to back.

Take care,

Eric

I think Don has asked an important question. Every chart I have ever seen lists the factors by Manufacture not by style of film. The chart I have and use in the field has several different brands of film and they are all slightly different.

The films Bruce uses the most are:

Tri-X 320 asa rated at 160asa
Hp5 rated at 200
Tech Pan ? rating

Since he uses Tri-X for most of his work I would imagine the chart is most accurate for that film. But as I mentioned I have used it for APX 100 and FP4 with good results.

Nothing beats doing you own tests though. As they always say, your mileage may vary.

In the las issue of PT mag, Howard Bond has some reciprocity figures, they are a little bit different than Bruce's but somewhat close. I would be mor ecomfortable using this than the curves supplied by Kodak or Ilford.
