Ok I think I have got the answer to the question I asked:
(The question: How do I calculate an exposure for zone X for the fomapan 100 exposed for the box speed (100 ISO) in the above illustrated...
Thanks everybody for your help. I have indeed used the method in AA the Negative first thing, and I got and EI of 40 ISO, I also tried BTZS method (after having read the book) but the result was...
Hi, I know the topic has been discussed before and I have studied lots of posts (and books). Anyway as I've always been a slow learner I have some doubts.
I want to test Fomapan 100 in Rodinal...
Thank you for all suggestions. Some months ago, when I made tests for film (fomapan 100 classic, Stouffer step wedge, BTZS procedure) I got consistent charts (I suppose). It's when I use the data in...
It still works, but now and then I get mistakes (the problem may be with me). I've gone through a couple of papers which made my doubts increase (Ctein, Post Exposure and Exposure Metering by Jeff...
Thanks for answering
It's a Pentax digital spotmeter. I cannot test by comparing because I have no other trusted meters.
Hello, I want to test my lightmeter. Is there a forum where the topic was already dealt with?
Thanks
Luigi

I built a wooden tripod some years ago.

It seemed quite alright, but when I did what Ansel Adams suggested in his book (catch...
Thank you very much
Hi, thank you for sharing your project and ideas. I'd like to use leds for a 8x10 enlarger which matrix should I buy to cover 8x10 area? I feel more comfortable with raspberry pi, do you think your...
Hi thank you for the clear explanation. I've also discovered that my 2 lightmeters work differently. Of course one is a spotmeter (pentax digital) the other is not (profisix-luna pro). What is more...
Hello, I've just discovered that my Gossen Profisix meter (Luna pro) produces the same couple f number-shutter speed once I set the EV. For Example if I set EV 4 at 100 ISO I get f 16/ 15 seconds. If...
I needed a lighter camera, as I can no more carry heavy bulky 8x10 cameras (I've got a fantastic Sinar 8x10).204758204759204757204760
it weighs only 2.5 kg (without lens)
I looked for a Gralab, but they seem to be sold only in the USA. I thought about one of the light-tight trays, but eventually I've bought a timer. This one 192645 which is available in Europe and...
Wow, lots of suggestions and ideas. Thanks everybody. I think I 'd like to get one of those light tight trays. I have to find a suitable one in Italy (that's where I live). Alternately I may stick to...
Extremely interesting, thanks very much
Luigi
Hi everybody,
I do much of my film developing in trays, in complete darkness. I have to check the time for proper agitation, so a simple acoustic timer won't do. Is there a timer which shows the...
How to open it?
I managed to unscrew the front group, but it seems there is no way to separate the two components of the front group. Are they stuck together?
Please help: I desire to remove...
Here are two images to show the effect (hope it is visible) and the inside of the cone that is matt painted black

Hi everybody.
Last year I bought an Omega enlarger at a reasonable price. Now I'm fighting with lens cones. I use both 135 and 150 mm lens and luckily manage prints with a single lens cone (the one...
hello. Can a Jobo 4531 accept a 2509n reel?
Thanks. Luigi:confused:
Hello. I'm going to run tests fp4+, hp5+ and delta 100 for the correct sensibility, n+1 and n-1 developments (procedure as described in A.Adams books). I usually use 4x5 and 8x10 formats for my...
thank you everybody:)
Hello everybody. So far I have developed FP4+ (4X5") in Ilford ID11 following the times suggested by ILFORD. I have always used a Jobo daylight tank.
Now I want to turn to developing in trays. ...
I managed to find a heat absorbing screen and bought compact fluorescent lights. I was impressed by the detail that these new ones are "fast start" lights. This means that they can be used with a...
As I promised, here are some pixtures:
1) the enlarger in all its splendour;
2) the rail
3) the effect of heat on a sheet of plastic
4) the 4x4 grid of lights
:D quigon
I visited the site of Aristo industry and I discovered that an 8x10 cold light head only costs $ 2538.
I don't want to upset :( anybody, but I spent less than 100 euros till now (not including the...
Thanks everybody!
I can't show any pictures for now, as I own no digital camera, (I'll borrow a friend's).
Anyway, the arrangement of the bulbs is 4x4. Each bulb is 40w. Between bulb and bulb...
hi everybody. I have finished to build an 8x10 b/w enlarger. I used the book by Ansel Adams as a guide. It is horizontal. I used a couple of opal plastic layers for diffusing the light of 16 normal...
thanks Nick, I found a couple of instruction manuals (two different types of spotmeter but practically the same as spotmeter III) on the Pentax USA website.

hi I've just bought a Pentax spotmeter III. Where can I find a manual for it?
thanks
