I should do a better job of proof reading. I am not sure how clear I was.
So, just to be clear: I can do 12 16-bit 3f scans of 4x5 film per hour on the X5 at the highest optical resolution (this...

I would agree with Frank and try all four. I have never used the Creo, so I can't comment on that, but I've used the X5, 949, and X1 (which you didn't mention). In my tests, I can't really see any...
Thanks, everyone. I realized I had neglected to click on "Relevancy" instead of the default, "Last Posting Date". I assume everything that applies to lenses also pertains to loupes.
I am very...
Hi All,
What do you use to clean you loupes and lenses? I did a search on this site but was unable to find a thread addressing this.
I have a Rodenstock 6x Aspheric (really big glass) and a...
I have bought a number of things at KEH over the past year. I have had nothing but great experiences with them. Almost everything I bought was as it was advertised. I did buy two lenses (each at a...
Thanks, Tiltody and Paul, for responding.
I neglected to look at my images, after I uploaded them. They are much too small here to see the smallest numbers clearly. Allowing for the fact that...
To everyone who has contributed to this thread,
I have started a new thread, "Back-focus Images", that show my LensAlign tests as well as a shot of a friend that is representative of all of the...
Thanks, Brian.
When I get back to North Carolina in February, I will check the camera with another lens. I have a 210mm Rodenstock that should do nicely.
David
Actually, the first one is from a distance of 54"; the next, 75"; the last, 150". All measurements are from the front of the lens to the plane of focus.
In the first image, 54" from the subject,...
Here are some images of my tests with my Linhof MT3000 and my Cooke 229mm Portrait lens. Thank you to everyone who tried to help me figure out what was wrong. I thought I would include the LensAlign...
Thanks, Tlitody for responding. Both the lens and the camera are new and under warranty, so I'm not touching anything. I'll send both the camera and lens in to be tested and corrected.
Dan,
I...
Thanks for replying, Dan. The 2" is an estimate. For the LensAlign tests. I shot from the three different distances with the lens wide open at f/4.5. While the DOF changed. It looks like the numbers...
I used about 20 Fidelity film holders, some used, some new. I get the same results with all of them.
r.e.,
I have already spoken to the folks at ZGC who work on Cooke lenses here in the US, but I have not spoken with Cooke directly. I will give them a call soon.
Thanks.
Thanks, jp498. That pdf on the Cooke lens is full of great stuff. I'm not sure how the chapter on uncommon optical behavior relates exactly to my problem, but I just scanned it. I'll be sure to read...
Actually, I misspoke. The adjustment is not a diopter. It is a focusing adjuster. I have the loupe focused right on the grain in the gg. I have used two different loupes: a Rodenstock 6x Aspheric and...
By the way, I have tried these tests using 20 different film holders, and the results are consistent.
David
My Rodenstock 6X Aspheric Loupe has a diopter adjustment. When the grain of the ground glass was in focus, I gaff-taped the adjustment ring, so it wouldn't move. I made sure the grain of the gg was...
I asked Guy at ZGC who are the folks who Cooke to repair their lenses. He said that to his knowledge, there is no special focusing technique to use with this lens and he is unaware of any problems...
Bob,
Thanks for your response. I have left a message with Martin concerning my camera and lens. I understand he will not be available for while, which is fine. I'll continue to compensate until he...
Jp498,
Thanks for your response.
I never stop down after focusing. I always focus at the aperture I'm shooting, which 90% of the time is wide open at F/4.5. For now, I have shot only in the...
Thanks for the suggestion. It sounds great. Learning how to better use my soft focus lens would be so helpful.
David
Greg,
Thanks for asking for clarification. You are correct in your assumption. I did focus on the ground glass using a Rodenstock 6x Aspheric Loupe. I developed the sheet and saw the actual point of...
Hi all,
I use a Linhof MT 3000 with a Cooke f/4.5 229mm lens. I have tested the focus four times from three different distances using the LensAlign testing setup. In all cases, the camera/lens...
Hi all,
Do any of you know of any excellent workshops in studio portrait work (H&S and full body)? I don't plan on doing my own processing, so I am most interested in a workshop that focuses on...
Since having Edgar Praus recommended to me on this site, I have been using Praus Productions in Rochester, NY for the last couple of months. I have sent Edgar black and white and color negatives as...
I've been using the ColoMunki Photo Color Management Solution, which is $374 at B&H ($449-$75 mail-in rebate). It's a spectrophotometer that you can use with both monitor and print calibration. It...
I have used Hahnemuhle Fine Art Pearl. It's somewhere between matte and glossy, more towards a matte in my opinion, although it says glossy on the box. It's a beautiful (although thick) paper and...
Thanks, Bob.
I'm not sure that I understand completely. Why the range then? If it's diffraction, why not just say that diffraction will be a factor with apertures smaller than f/22? The 210mm has a...
Hi All,
I have a few Rodenstock lenses. Rodenstock lists ideal working apertures for their lenses. What does that mean exactly? For instance, the 75mm f/4.5 has an ideal working range from f/16 to...
Thanks Scott and Bob. They have everything I'm looking for.
David
The 2 /14" sleeves aren't urgent, so if you have a place that doesn't sell them, that's fine.
David
Hi all,
I've been scared off of Light Impressions, because of some recent really negative reviews on this site. I used to use them, and never had a bad experience, but that was years ago. Does...
Alan,
In response to your question, I don't mind the softness with portraits of women. In fact, all of them I've worked with so far prefer it. I don't mind using a ND filter in those situations. I...
I, too, have had great experiences with them. I've bought two cameras, six lenses, and loads of other stuff. Twice, I had problems with lenses. One a 75mm rodenstock, the other a hasselblad 120mm....
Thanks everyone,
I kept the fresnels and had some good results with a couple of 650 watt tungstens and some foam core for some fill. Plus I got a couple of old Lowel lights (1000 watt). I'll...
Thanks for all the suggestions.
I gotten back some film from Praus Productions. The quality and service are excellent. It's worth the extra time. Even with the cost of getting the film to...
Thanks, Vinny.
I think I finally got my night time spot metering down. At least it matches the good exposures on my digital camera. I thought that the dynamic range of film is greater than what is...
Thanks everyone for the help. I did take my Fuji PA-45 off the camera when I pulled the tabs for the instant film., and it was a big help. I'll probably send the C1 to Bob Watkins for a check-up. I...
Thanks, Vinny. As a beginner, I want to be clear. In this "night" scene the brighest highlights are the center of the lights themselves. Do you mean something that is not the lights, but rather looks...
