I seem to remember Deardorff making a camera for one of their clients
who wanted to use it at the 39 World's Fair. There was something unique
about the size and I'm hoping one of you might know...
Anyone have any experience with these? An instruction manual perhaps?
I've been using TMY II for many years and have always processed the same way in my Jobo Expert drums and never before have I seen this particular issue. Static is definitely not an issue as all the...
Anyone experiencing pin holes in the current supply of T-Max 400 type II? I hardly every get dust problems on 4x5 using my routine technique for cleaning, but in a batch of around 75 sheets I just...
Thanks for your insight. I have since experimented with a "semi-gloss" paper and found that it closely resembles the old Agfa Portriga Rapid I sorely miss. Now I'm just trying to sort out the...
Has anyone used Fomatone 132 and 133 paper who can describe the
surface and maybe liken it to some traditional papers I might be more
familiar with? One is described as "matte" and the other as...
I first marked the tape with a .3mm mechanical pencil and proceeded to go up and down the scale marking all the other aperture settings, using the meter and probe to confirm the incremental changes....
Measuring the comparative diameter of these two shutters is not as easy as you might think. The Compur shutter has many more blades in its diaphragm creating what appears to be almost a perfect...
The diameter of the fiber optic probe is roughly 1/4". When holding it against the crosshairs of my gg, I seriously doubt my measurement would have been more accurate with the fresnel in place. ...
Actually, there was nothing at all wrong with this shutter. I simply wanted to move the lens to a more modern
Copal shutter like most of my other lenses.
First of all, I removed the fresnel as this was simple in that it was mounted between the gg and my eyes. Since I was not taking any sort of an absolute measurement of light, but rather was using...
White flat back tape is simply artists tape, similar to masking tape, but thicker, a true white color and without the crepe texture of masking tape. Here's a link to a source...
I have been wanting to mount a 203mm Ektar in a modern Copal 1 shutter for some time now and just assumed that adapters would have to be machined to accomplish this. Fortunately, the lens I had was...
I was recently faced with the challenge of photographing from a low angle in very muddy, rocky and sometimes dusty conditions. I first tried this on my knees with a focusing cloth and quickly...
I have used cardboard slide mounts as gel holders.
I've tried a couple of the Photographer's Formulary reducing agents, but have not seen any change, even after 30 minutes.
Does anyone have some insight on this? Are tabular grain films immune from...
Here's one I've been trying to capture for a few years. There was always something not cooperating until just a month ago.
203 Ektar with my little Anba Ikeda 4x5 on TMY.
It's been awhile since I last posted an image, so here's one from my last trip to the Greek Isles.
Depending on what type of glue/locktite was used, this may require some heat and/or solvent to soften. I would first try taking a small sheet of innertube material or one of those rubber jar lid...
I have used an old 2"x2" Tiffen filter (flat and thick enough) with a golf ball cemented to it with JB Weld. The golf ball makes for a very comfortable handle. With this combination, I have gotten...
I was recently given a Gossen fiber optic probe that fits the LunaPro and similar style Gossen meters. I'm trying to use it to measure the absolute light output of various flat panel displays and am...
If the image was in focus on the film when focused on the GG USING the Fresnel, then you would simply measure the thickness of the Fresnel and make shims = to 2/3 of that dimension. Make certain...
I've written an article about the importance of using a proper lens shade to reduce the amount of non-image forming light from getting inside the lens and the camera. In situations where you are...
I simply rub down the dark slides with waxed paper (Cutrite works for me).
If you have an i-pod or an i-phone, you can down load an inclinometer for .99 that will give you extremely accurate readings. Just hold it against the standards and adjust for 0 degrees. Works very...
Optical coating reduces the amount of light reflected from the surface on which it is deposited. Uncoated glass reflects about 4% of the light striking it. Your lens is made up of a number of glass...
What Gem said about exposing for shadows and developing for the highlights summarizes zone system B&W photography. The first reading indicates what is needed to expose shadow areas sufficiently to...
You might want to be real careful doing this as Dektol is not a single chemical, but a combination of powdered ingredients that must all be dissolved in water to assure the correct proportion. If...
No, as I rarely make contacts from 4x5 or 5x7 negs. There's no reason why you should have any problem doing so. In fact, this technique should make it easier to do any dodging and burning as that's...
What you are referring to is sometimes known as dodging and burning masks or pencil masks. I have that material and got mine either from a college book store in Ann Arbor or Utrecht art supply. I...
Quite a story. Ask your dad if the type he flew in had those strange bulges above the fuselage. I think those housed the equipment for sniffing out the subs. I seem to remember building a plastic...
"Delapalachia" Somewhere in Georgia.
Okay, I found this on the web. More detail than I was aware of:
the aircraft was purchased by Jim Flannery in August 1967 for use as a cocktail lounge atop his restaurant in Penndel, Pennsylvania....
This was made in the late '70's early '80's on a trip to the Princeton NJ area. I believe this was in PA just on or near the NJ border. They still kept the bubble port just behind the cockpit...
Taken with a TF (tiny format) SLR (Pentax 110 SLR) on Verichrome Pan. The galley of the restaurant is upstairs in the fuselage of the Super G.

Ios, Greek Isles - 2009 "Open & Closed"
Funny that we independently discovered the same funnel. I made a little block out of wood to enable me to attach to a shelf. Perhaps this will give you an idea for a quick release attachment for...
what camera are you using?
