Nailed it!

I agree with @chuckroast and perhaps the thread title would have been worded better as "What ASA are you using to achieve the aesthetics you desire in your black and white prints?" thus making film speed assignment purely subjective. That is the bottom line: using the product and tools in a...

I have to assume that in his sharing his behavior to get best results with Kodak films, he was downrating the ISO when programming his exposure meter. That would be a speed modification. Also, I believe he shared the information as practical matter to achieve real world results, not impugning...

If memory serves, (best check the archives, though), I believe PE stated that he exposed Kodak films at 1/3 to 2/3 stop over as a rule for best results. He was, of course, intimately engaged in the design and production of Kodak films.

Many years ago I had similar markings; these were caused by light leaking by the elastic in the arm holes. I have since done all my tank loading in the changing bag in the darkroom with lights off. Problem solved.

I got those exact marks in exactly the same place; I finally figured out that I was wearing my Fitbit while I was loading the film on the reel. The digital watch was momentarily illuminating and generated enough light in the changing bag to fog the film. Problem disappeared when I stopped...

I think you may be correct in identifying this mystery film. It does indeed have a very thin anti halation layer; it is definitely not opaque and one can see through the film when held up against the light. Also, it has much finer grain that I expected for a 400 speed film which would match your...

I just finished a 100' roll of UltraFine Finesse 400; the color of the emulsion and the perforation shape in your photos is identical to my last rolls I spooled yesterday. I was not able to discover the origin of Finesse but I'm positive that it's from the same stock as yours. I purchased...

Spot on! +1

What ticked me off was that I ordered and paid for 400 speed film with the expectation that it wouldn't actually come in at advertised speed; coming in at 100 was a nasty surprise. As I said, it just barely made 100 with my testing methodology and might be closer to 64 as measured by aparat with...

I am a firm believer in Sunny 16, relying on it heavily since the '70s when I first learned of it. However, I find it odd that most of the published information does not take into account elevation. Sunny 16 was ultimately reliable when I was living in LA and in Seattle; when living in Tucson it...

Seems like this is probably the proper place to post this, so...just ran a quick and dirty zone I speed point test (0.1D) on a 100' roll of UF Finesse 400 dev'd in D-76 stock @ 7.5' @ 20C and got (just barely) an effective film speed of 100. Used the Minolta Spot to measure the 0.3 stop...

Facts to add to the mix: I have terrible allergies and need to use a sinus rinse regularly. The rinse is made with 250ml H2O and a powder mix of NaCl and NaHCO3 in a 3:1 proportion. The NaCl grains are about 5x to 8x larger than NaHCO3 grains in size. I combine 3 Tbs to 1 Tbs in a plastic cup...

I agree. I left the discussion for just this reason.

Pentaxuser: My experiment was sponsored by all the speculation in this thread. I decided that I should go ahead with actual preparation and development to see if the 'fears' expressed in this thread had merit. So, my advice to you is to follow my footprints and develop a few test frames and see...
