Very strong ball head.
In accordance with Seconic manual the decimal scale displays in 1/10th of a stop. Not time, not aperture, just a stop. So when Seconic measure 5.6 & 5/10 or 4/10 it will be yours 6.8 aperture....
The problem may be caused not by the gear rack itself, but the wood. The thing is that the ebony wood from what the camera made happens to be very sensitive to the humid. I'm using Ebony about 7th...
That's the amplifier!!!!!!

In accordance with ASHRAE, the darkrooms required 20-30 cfm of fresh air per person. To have 1 air change per 3 min. giving you 20 air changes per hr. This is craaazy big number and really...
I never see that mechanizm. But if it is a planetary reduser, than it will allow to turn a I high speed wheel when the outer low speed wheel hold unmoved. The speed ot rotation will change, but it...
I never used Arca, but why you cant measure it. Take a rule or tape and measure the bellows extension. You do it one time and will know forever. And second if both standards having the same...

If it is plastic, then its probably soft enough to trim it with woodworking hand plane. Of course you need a sharp plane or better a block plane and some understanding in the woodworking, or at list...
With many today holders, polarizer can be rotated with out rotating the holder itself. The problem is that exept Lee, nobody making hoods for their filter holders.
All holders for rectangular filters basically the same and main purpose of them to hold the filters. Today most of the holders can hold a polarizer and a 2 or 3 filters. If you getting that...
That's what I wright Randy. Film in the tray with emulsion up. Unfortunately the Google translated it in absolutely opposite way.
Сергей, я не специалист в рентгене, я только перевожу. Все склоняются к мнению ,что у вас неравномерное проявление. Во первых я бы убрал стекло из кюветы. Фильм достаточно прочная вещь и он не...
[QUOTE=IanBarber;1445874]Bob, how do you change between camera presets[/QUO
To change between cameras press and hold "ISO1" button and after press "Mid Tone" button. One press on the mid tone...
You right, the best pictures was made without a light meter in many cases.
But I’m certainly not that good and I’m using Sekonic. Before I used the spot with mechanical calculator and get used to it...
So in most of the situations you don't nead an average value. Am I right?
Let say you light and shadow readings 10 EV apart. So what will you search for in the scene after pressing the average button?
Let say you have two readings. One for higlites and another for shadows, and those readings a 4 stops appart. In that case if you use average it will be exact in the middle betwin your readings. If...
No. In yours exemple you having an ideal situation. You already know what you want to be a middle gray value and it is the first measurement. The second and third measurements confirm that the...
I have Omega enlarger and I never had problems with lens cone. But mine cones are black inside. Are you cone black? ore maybe you have some chromium plated lens mounting ring.
The name of the Chinese tank manufacturer bw-king. He is a member of this forum and he is the only seller of his tank. You can contact him if interested. In my opinion the Chinese tank better made...
The simplest solution probably is to obtain any type of not expensive, broken, scratched, or used old filter with 95 mm tread ( you need just one), remove the glass and use metal part as an extension...
Stain used darkroom made from black plastic like for years.
Plus diopter lenses can be used for macro with any large format lenses successfully and they are not expensive at B&H.
In the aperture priority mode the EV scale displayed on the bottom, and it divided in 1/2 and 1/3 of the stop. It is just necessary to get used to it. I always measure highlights first, and save it...
Sometimes he respond not right away. Be patient.
So, what the problem. F16 7/10 almost the same as F16 2/3. Many shutters having 1/3 scale.
To avoid this, before pulling dark slide with hole out, slide in some sheet of film between the dark slide and the holder and after pull dark slide together with that film out. And don't worry this...
You welcome. Short rail can be used as an extension for example when you need a long draw for close up's, or it can be used separately, when you working only with the wide angle lenses, it is more...
No parts any more from Toyo, but the lens boards and bellows can be interchanged with the new currently in production. But the new ones expensive. Better to get some old o broken camera on EBAY if...
Long time discontinued.
Some old fashion drafting tools sets used to include a measuring calipers with micrometer screw. They looks same as the calipers to draw a small circles but instead of one head to be with sharp...
I don't think the drilling is the best choice. A 100% you will be of the center and finally will damage the wood. If I would do it, I would use only a hand file and file the rivet head off. This will...
Large format photography much different from Digital SLR. Before you start collecting staff and equipment get some understanding about the field of photography you are going to enter. Look for some...
