If you are lucky enough to own a Calumet Shutter Speed Tester, you know it is not exactly ideal for testing large lenses and shutters. I have owned one of these handy little devices for over ten years. I performed a modification/upgrade near ten years ago that makes the tester much more suited to testing large lenses and shutters.

This modification/upgrade is not difficult, but does require a little ingenuity and proficiency with a soldering iron. With a little planning and a good junk box full of odds and ends you can construct a remote trigger for the tester.

Follow the link HERE to our main web site which will take you to the ‘ARTICLES’ area and scroll down the page to download the PDF titled “CALUMET SHUTTER TESTER MODIFICATION: AN UPGRADE FOR THE LF SHOOTER.” This modification/upgrade has served me well over the years. Hopefully you will find this of interest also.

As much as I try to not talk continually about the gear, it seems that I always end up talking shop anyway. So, here I go again talking about another project. Having built two vertical pano cameras for Susan I promised myself no more camera building. Well, I do not seem to listen to myself all that well. I have this thing about big negatives. I have chosen the 8×10 to be my every day format. But there are times that I envision something just a little larger. In reality, my favorite format is 11×14, but the camera I have been using weighing in at about 24 pounds limits its usability. The idea of a more user friendly 11×14 has been rattling around in my head for some time.

The nice thing about building your own, is you can pick and choose the features and design that best suits you. This is exactly what I did, and I ended up with a camera that is a conglomeration of designs.

The end result is what I call the Ultra-Light 11×14. Here are the specs;

FORMAT — 11X14
FILM BACK — Horizontal/Vertical
BELLOWS — Max: 36.0” Min: 5.5”
FRONT SWING — Limited by Bellows
FRONT SHIFT — +/- 2.0”
FRONT RISE — +/- 3.0”
FRONT TILT AXIS — Limited by Bellows
FRONT TILT BASE — Forward: 45º Back: 90º
REAR TILT — Forward: Limited by Bellows Rear: 35º
REAR SWING — +/- 10º
GROUND GLASS — Acrylic
WOOD — Cherry
FRAME — Composite & Aluminum
FOLDED — 18” x 19” x 6”
WEIGHT — 13.5 lbs

The most important thing here is the last item, Weight! Once all of the camera was finalized, Susan had to build a pack to haul everything. Took several weeks, but I now have a complete 11×14 packable camera system. The pack carries the camera, three lenses, accessories, three film holders, and weighs in under 45 pounds!

Now it is time to get out and get back to what is important, making photographs. This, I hope, will be my last camera building project.

P.S. Take a look at my previous post titled, “THE VIEW CAMERA IN THE FIELD” November 25th, for another photo of the Ultra-Light 11×14 with pack on its second outing.

Almost forgot about the other little project we undertook a few months back. Susan found a KB Canham 4×10 and it ended up in our possession. Because we strive to keep our equipment as homogeneous as possible, the new camera required a few modifications just like my 8×10.

Everything around here seems to end up in the shop before it hits the road. So, here is another little story about camera modification. Take a look at the article WHY MODIFY ANOTHER CAMERA? to see what happened this time.

The good news is we took the cameras on a little outing a few weeks ago and the negatives were just fine. No light leaks, nor any other strangeness. Guess this one is ready for the road. Time for fall, then winter, and much cooler weather to get out and haul some equipment around.

I have said this many times and I will repeat it here; I want the hardware involved in the process of making a photograph to be as transparent as possible. By transparent, I mean that the equipment should not be a distraction when out in the field making an image. I want the hardware to fit my way of working so well that I do not have to concentrate on working with it. I do not want to have to fumble with the camera and be distracted by some aspect of its operation that is not fluid in its use.

The way I make my cameras as transparent as possible is to modify them to whatever extent necessary to make them fit me. Yes, this requires I disassemble the camera and make modifications. I would rather do this now, in my shop, where I can work out these things so they do not hamper me later in the field.

What is all of this about? Well, I just acquired a new K.B. Canham 8×10 camera and in order to make it fit me better, I had to make a few modifications. If you are interested in seeing what I did, take a look at “NOTHING HERE REMAINS THE SAME; PERSONALIZING MY K.B. CANHAM 8X10” for a look at what I did.

Have fun reading this account, but remember kids. . . you may not want to try this at home!

I have had a lot of really positive feedback on my recent text titled Bellows Building. I would like to thank everyone for the kind comments. There have been several inquiries for more information regarding Railroad Board, exactly what it is and where to purchase.

Railroad Board is the best material for bellows ribs. It is a smooth, thin, Bristol-type board, colored on both sides, that is used for signs, posters, mailing cards, tickets, tags, and so forth. Thicknesses are 4 ply (about .017″ or .43 mm) and 6 ply (about .022″ or .56 mm) and is available in 22″ × 28″ sheets. I recommend 4 ply for small bellows smaller than 8×10 and 6 ply for larger bellows.

You can purchase Railroad Board by the sheet or in bulk packages from Dick Blick. I would recommend black material and here are the stock numbers and the direct link to their on line CATALOG ;

13105-2002 Black 22″ × 28″ 4 Ply
13105-2102 Black 22″ × 28″ 6 Ply

Hope this answers any questions and good luck with that camera rework and bellows building project.

So, what to do? I say make your own using plywood. Correct. . . Plywood. It will not warp or crack and is easily obtainable. All you have to do to make it look decent is to veneer the outside with the same wood as your camera and finish it. You will not be able to tell the difference from the solid wood boards.

Take a trip to your local woodworking store, or search on line, for some high-laminate birch plywood in the nearest thickness to the lens board that your camera uses. Hobby shops also sell suitable high-grade plywood. You will also need a few pieces of veneer of the correct type. I cross laminate the veneer and it looks just like the multi-piece hardwood boards. Look on the Internet for tips on wood laminating, it is not that hard to do. Carefully measure an original lens board and using a saw and router duplicate the profile and sand to fit your camera.

The hardest part is drilling the hole for the shutter. Here you will need a Forstner bit that is the closest to the size of the shutter you intend to mount. Remember that most shutters are metric, so choose a drill that is just under the desired size. You can then us a round file and sand paper to adjust the fit.

Once you are satisfied that everything fits, it is time to finish the board. I black the back of my boards along with the light trap offset and edges. I use black India ink which penetrates the wood and dries to a flat, non-reflective finish. Only the veneer front requires a fine finish. I use varnish, you can use spray acrylic if you like. You may have to apply stain to match your camera, experiment on a scrap of veneer first.

It is really easy to make your own high-quality lens boards. The last time I did this I made about six blanks and I still have extra undrilled boards on hand.

Once you become a serious darkroom worker you will eventually want a real darkroom sink with running water. The question is, to buy, or to build? Certainly, if you have deep pockets, you can buy a commercial stainless steel sink. You can even have a stainless sink custom fabricated. Just be forewarned, you are looking at a serious amount of money.

What most do is build their own sink, typically from wood. This is my favorite construction technique and allows me to build a very functional sink to any size required. In the previous post titled “NOT THE KITCHEN SINK” we showed what it took to build a large darkroom sink from wood. Robust construction is essential to make sure the sink does not flex. Flexing can cause the finish to crack and begin to leak.

My philosophy of sink building is to build the thing like a boat. Using construction robust enough to sail the ocean. That way it is strong enough to stand up to most anything. Once complete, I like to climb into the sink and jump up and down. If nothing moves, creaks, or breaks, I am satisfied that I have a good strong sink.

Waterproofing is the next order of business. Caulking all seams is a must to insure no leaks. Next comes some form of durable, waterproof coating. I built one sink years ago and used fiberglass. Never again! Way too messy for me, and I hate working with the stuff.

After much research I found a suitable coating for my darkroom sink. Tile-Clad® HS Epoxy is a two-part, commercial-grade, epoxy-polyamide coating from Sherwin-Williams. This epoxy paint is used in power plants, offshore structures, schools, storage tanks, laboratories, hospitals and marine applications. This stuff dries rock hard and is near impervious to most chemicals.

I have found that two generous coats of Tile-Clad® makes a great smooth waterproof finish for a darkroom sink. You can also have the paint tinted to most any color you desire. Most any Sherwin-Williams store should have Tile-Clad® and be able to tint it for you. Be prepared, this material is not cheap. Seven years ago when we built our last sink it was about $110.00 for a gallon of part ‘A’ and part ‘B’ which, when mixed, makes two gallons of paint.

The main points to keep in mind when building a darkroom sink is make it robust in construction, waterproof, and resistant to chemicals. Whatever finish you choose, whether it be fiberglass or Tile-Clad®, if the sink flexes, the finish will crack. Build your sink like your life depends on its integrity and you will never have leaks nor have to build another. . . unless. . . you decide you need a larger one!

For those interested in why we chose this chocolate brown color, the first sink I built was white. Amidol and Pyro left stain spots all over the sink. We chose the closest color to the stains from the color swatches from Sherwin-Williams and had the paint tinted that color. Developer stains do not show!

Cabinets for storage would be constructed at each end of the sink with slots for trays in between. There would be space in the right hand end for the water chiller and racks for chemical storage at each end. The backsplash would be a copy of the old one, only larger, and would contain the same plumbing, including filters, two mixing faucets and temperature control unit.

Having determined the necessary measurements it was just a matter of gathering the materials and getting to work. It took about three weeks to complete and install the new sink. Construction was my usual battle ship, massive over kill, design, using plenty of nails, screws, lag bolts, caulk and paint.
