Shame. Azo is being made in Brazil, for several months now at least.

John: I had an unsuccessful attempt (flare), at shooting directly at the sun while it was about 10 desgrees above the horizon, but one hint I can suggest is that when I stopped way down to f128 there...

Thank you all for your input.

I think it would also be prudent of me to expose a sheet of film at zone V on a uniform subject to test the brush and my technique thus ensuring that the negatives...

I understand that brush development yields the most even development on uniform subjects (open sky).

I read an article in View Camera in August 1993 explaining 4x5 brush development which explains...

David et. al.: This breaks from the original post... I have ordered my first batch of PL100 and will also be doing some testing with ABC. The less testing the better IMHO. What developer are you...

Jim: I'm curious, what e.i. the PL100 was rated? Did you do testing to determine it?

I'm considering this film but want to get as much info as I can before I try it.

Many thanks,

Matthew

Ignoring the math, if you have a light meter you can take a reading at your original height then take another at your next column height. Take the reading difference on your meter and adjust your...

Thanks to all for your excellent input.

I do use a compendium shade and it seems to me that as the camera design is square I should not be getting the same amount of density increase on all 4...

My agitation is continuous for the first 30 seconds then I lift one side of the tray about 1 inch every 15 seconds (changing sides I lift each time).

Bellows Flare!? Can anything be done about...

I have recently made the jump from shooting 4x5 (TMax100 with D76) to 11x14 (Ber gger BPF200 with PMK) with a whole lotta learning curve and fun with some frustr ation in the process!!

In some of...

I have noticed that Packard Shutters are reasonably priced on Ebay but I really know nothing of how they function. I assume that they are behind the lens, but how are they tripped/how does the cable...

Your view through the finder (compared to the view on the ground glass), makes a difference depending on how close you are to the subject. It seems that these work best/are most accurate when you ...

I have read the papers from Ed Buffaloe and Michael A Smith on AZO printing. As Mr. Smith suggested, I picked up an R40 300W bulb. The bulb has a seemingly s ignificant hot spot in the centre of...

I would like to get very accurate development times for my film processing and t hought that density readings of test strips would be the best way to go. I have read that one needs a densitometer...

I have a 480mm Nikon Process lens with a slot and sliding lever to cover this sl ot. Can anyone tell me what and why this is for and why the numbers (which see to corrispond to degrees)?

Thanks...

Regarding my EI: I am still evaluating my tests and shooting based on just getting started with BPF, PMK Pyro, Azo & Amidol. I'd rather too much density than not enough, and I may revise my EI as...

Does anyone have experience with the reciprocity characteristics of Bergger BPF2 00? They supply a chart up to 30 seconds metered exposure but I frequently expo se well beyond 30 seconds. How hould...

Hi all:

How/why/is the image circle of a lens affected by the stop (aperture size)? Is the stated IC given by the manufactuer always at a specific aperture? Is the di fference in IC between the...

I am taking the plunge to 11x14 (from 4x5). I have a 480mm Nikkor (process lens I think), and would like to get one lens with a shutter. I beleive a wide angl e lens (210 - 360mm), will do me. I...

I am building a vertical print washer from scratch and wanted to know if the wat er intake should be on the bottom or top and the outflow be on the bottom or top . I heard that fixer is heavier than...

I am looking to purchase a used 11x14 folding camera. New is too expensive. I have been watching ebay and there have been a couple of 11x14 studio cameras but I'd like to take it into the field. ...

Mark:

I recently went through the same scenario as yourself and wound up using Darkroom Innovations testing "service" (after reading BTZS), for the film curve analysis, EFS, etc. As a result...

Further to a thread of earlier today, I am going to try Bergger BPF200 developed in PMK Pyro. I shoot 4x5 and will be enlarging. (I'd love to have a 11x14 and contact print only but can't seem to...

I currently shoot 4x5 TMax 100 EI at 83, developed in trays with D:76 1:1. I am pretty satisfied with my results on the whole but recently I feel that the tona l scale is too contrasty - the middle...

A week ago I posted a message asking if I could convert my D2 to a diffusion enl arger by adding a piece of diffusion material. I recieved a number of replies a nd suggestions to follow other...

Having read of the differences in final prints between using a diffused light so urse or condenser, I am curious to see the differences on my own prints. Not ha ving oodles of $, space, etc., I must...

I am looking for an introduction to Pyro developers what there positves and nega tives are - just to get off the ground and if they are commercially available or can only be made my mxing your own...
