Peter,
Glad you've found everything you needed. Sourcing mounting supplies seems to be getting more difficult.
Just FYI, I've never really used release paper, opting instead for a one-ply...
I've had problems with some films (TMY especially) retaining lots of dye when processed in PKK, a normal acid stop and Hypam or Ilford Rapid Fixer 1+4. In the case of TMY, some batches were almost...
Gary,
You have, in order from your eye to the lens, a protective glass cover, a Fresnel screen made of acrylic, and a frosted glass with grid marks.
The cover glass is fragile, but just glass....
Peter,
BufferMount is available in rolls if you don't mind cutting your own sheets. That's what I do now. Just Google search; I found several.
Trimount should be similar to ColorMount, if I'm...
+1. Michael has your answer
Sébastien,
I'll try to keep it simple.
Front tilt moves the plane of focus from vertical toward horizontal. It is good for things like flat fields with no trees, etc.
A tiny bit of front...
If it is working-strength solution it may have gone bad. If you are referring to the concentrate, it will likely still be good.
To test do two things. First pour a bit of the fixer into a clear...
I own both. An older El-Nikkor 150mm and a rather newer 135mm. Both deliver superb results. I use the 150 mostly, but switch without hesitation to the 135mm when I need to make a substantial crop...
Rick makes a good point. If there is a Fresnel screen of a focal length not well-suited to the lens focal length, there would be a definite hot spot.
The OP, however, has what look like loading...
Apertures nowadays are marked in f-numbers. The "f" stands for "focal length." These numbers are always given as fractions of the focal length of the lens. f/8, therefore, means that the optical...
Good question. A photo of the set-up in action would help.
Doremus
The former seems to indicate that the bellows may have blocked the light, or maybe some other obstructions. The image canted on the film indicates that the film was improperly loaded in the holder,...
Let's see... opening the aperture one stop doubles the amount of light hitting the paper. Decreasing it on stop halves the light hitting the paper.
Therefore, closing one stop would require twice...
Some Foma papers (e.g., Fomabrom 111) need a red safelight; the amber ones (OC filter) fog them fairly rapidly.
Using a red filter instead of an amber filter is fine; it's the shorter wavelengths...
Let's see... There seems to be a 240mm Tele-Xenar telephoto that was designed for the 3 1/4" x 4 1/4" (90x120mm) film format. If that's what you have, it may not cover 4x5 completely; you'll see...
Andrew,
I'll just address your question to me. First, though, please note the correction in post #11, pointed out by acrobatic_citron (thanks a_c). I hope that didn't confuse the issue for you. ...
Thanks for the correction! Typing too fast and not thinking clearly, obviously. Yes, f/22- , which is 1/3 stop more light than f/22.
I apologize to the OP and the rest following this thread...
Kino is right that we need more information. Kino is mistaken, however, that extending the bellows past infinity focus will reduce the image circle; just the opposite, extending the bellows...
Thanks Peter!
Glad you found the percentage method helpful. FWIW, I've standardized on just one sequence at 30% intervals (25% works too, but I've found that 30% is not too wide to be able to...
Andy,
There are a range of shutter speeds; some of them are off more than others, e.g., some are 2/3 stop too slow, some only 1/3 stop too slow. If you can get your head around my method, I'll do...
Here's my table of shutter speeds in milliseconds with corresponding approximate 1/3-stop fractions.
When I get my shutters tested, I convert the time in milliseconds to the closest 1/3-stop...
I think we're talking about an 80 second exposure here, not 80 minutes, which is not all that uncommon with larger prints (still long, though).
Monochromefan,
F-stop timing really works better...
Not sure what you mean by the question. I posted information specific to Beseler 45M... series condenser enlargers regarding positioning of the upper bellows. Nothing whatsoever to do with the 23C...
If you're printing, you'll need a stop bath. I use Kodak Indicator Stop mixed as per instructions. I find it more economical than buying white vinegar, plus the indicator is nice (toss the stop...
Gregg,
Sorry to see you go! I'll see if I can make it over for the exhibit from Eugene, not sure I'll have the time, though.
Love your work and the website.
Doremus
Well, I should have qualified that statement with an "often." Certainly, if you test and know what your results are going to be, and if you understand the principles behind the terms well, then...
Yep. It's a roll-film-get-the-shot-in-low-light thing. It's become enough of a "look" that some like it (and think it's technically good photography).
Doremus
I dislike the terms, period. Basically shorthand for sloppy guesswork.
Doremus
I'll second the suggestion for a good spray aluminum primer followed by a good-quality flat-black spray paint. I've done that with several negative carriers and have never had a scratching problem....
The terms "push" and "pull" are inherently imprecise and fuzzy themselves. Most who use the terms "push" and "pull" use roll film cameras and in-camera meters.
"Pushing" is most commonly regarded...
Monochrome fan,
Modify your approach to AA's book: Assume he knew what he was doing and that his descriptions are accurate and correct.
Any confusion, therefore, is due to misunderstanding on...
Here's a positioning guide for the Beseler 45M condenser enlargers that I've compiled from various sources over the years. Possibly helpful here.
Doremus
The rebates on the film look fairly clear, so you're not dealing with base fog.
The Pyrocat negative is flatter than the HC-110 negative, but that's to be expected. The stain adds photinic...
John,
Since you're planning on using a blue/green split printing technique, what really matters is that the panel you choose emits usable and fairly equal amounts of blue and green light. Take a...
Bleach WILL affect the latent image. Check out SLIMT techniques, where a rehalogenating ferricyanide/bromide bleach is used to bleach the latent image contrastwise (works on film or paper). I've...
The options above all impinge a bit on the image area. That's fine if you can live with that. In that case, you could simply tape some transparent film to an appropriate part of the film holder and...
Just to clarify: If you are using the condenser light source, you need to adjust the upper bellows to the right height for the size of negative you are enlarging. Originally, the enlargers equipped...
The Zone System works best with a spot meter for metering shadow values and with sheet film. With a sophisticated roll-film camera and matrix metering, I would approach exposure/development in a...
You should learn to be a bit more trusting. Why do you suspect that Ilford, a company that's been in business for decades, has a good reputation and is a leader in the industry, would sell you a...
