Well. . . that was a cheap shot, but maybe it got your attention. Care and maintenance of your photo equipment is something that is important. Take care of your equipment, and it will take care of you. We use a lot of gear that is made of wood. We spend a lot of time outside in harsh environments. But, all of our equipment needs protection from the elements. We wax everything. Wood, metal, plastic. . . they all get a generous application of wax.

Wax keeps moving parts moving smoothly and a well waxed surface is easier to keep clean. Dirt and contaminants do not stick to a waxed surface. A slick, waxed surface is easier to keep clean. Also moisture is not as much a problem. I can say that we wax most everything except the lenses.

So, what kind of wax should you use on your expensive equipment? We use only the highest quality Microcrystalline waxes on our gear. Microcrystalline waxes are far and away, the finest wax you can use.

They offer excellent resistance to moisture, food acids, alcohols, moderate temperatures and are pH neutral naturally. Another benefit is that they will not show fingerprints on treated surfaces. Microcrystalline waxes also dry crystal clear, never yellow, leave no chalky residue and resist dust as well!

What brand of Microcrystalline wax do we use? RENAISSANCE WAX-POLISH has been the #1 choice of museums, art galleries and institutions for the preservation of precious items for over forty years. Professional conservators, retailers, restorers and private individuals throughout the world depend on RENAISSANCE WAX to protect their collections and for in home use.

All I can say is, this stuff is great and highly recommended. It is SAFE to protect all of these Materials:

Wood; raw & finished. Leather, Parchment & Paper. Metal; Silver, Silver Plate, Gold, Copper & Copper Alloys (Bronze, Brass, Tin, Zinc, German Silver, Nickel), Lead & Pewter, Iron & Iron Alloys, Tin & Tin Alloys. Damascus; Stone, Marble, Onyx, Limestone, Granite, Brick, Tile, Terrazzo, Obsidian, Alabaster; Gems, Glass, Porcelain, Holloware, Bone, Ivory, Horn, Shell & Mother-of-Pearl, Gutta Percha. Dammars; Gilding & Gold Leaf, Patinas. Enamel, Lacquer, Japanning, Cloute, Pose d’Or, Pique Point, Varnish, Marbleizing, Stains & Artificial Graining. Plastics, Formicas, Paints, Polyvinyl Acetates, Esters of Polymethyacrylic, Polycyclohexanones, Fiberglas Epoxy Resins, and much more!

Guess you can say that we are sold on Microcrystalline RENAISSANCE WAX. You can find it at most woodworking supply stores and on line. A quick Google search will turn up a lot more information. Well worth the cost and time it takes to apply. A little “Wax On. . . Wax Off” and you are good to go most anywhere.

Do you cover the back of your view camera with the darkcloth before you pull the darkslide? I certainly do!

Have you ever experienced these pesky little light leaks along the edge of the film that seem to come from nowhere? Gremlins? Not really. They are caused by any number of things that can go wrong in LF. A holder that has a small leak only when the slide is out, one that does not fit tight in the camera back, a light trap that is worn, or maybe you stress the holder as you remove or replace the darkslide. Thing is, it always seems to show up on that one piece of film you really want to print. Light leaks were seldom a problem as long as we were shooting 4×5, but when we moved to larger film sizes it became more evident. I will say, without reservation, as the film size goes up, the problems multiply exponentially!

The good news. . . the solution is simple, and for us, solved 99% of the light leak problems. Leave the darkcloth on the back of the camera while exposing the film. This way, even if there is a problem with the holder seating or the light seal being broken when removing or replacing the slide, you greatly reduce the probability of a leak.

It has become a habit to clip the darkcloth to the camera back once it is setup, and it remains there till the exposure is finished and the darkslide is back in the holder. We both use small, inexpensive, plastic spring clamps available at the local hardware store, to clip the darkcloth to the camera back. Simple, quick, easy. . . and. . . it works!

The question comes up every now and again about getting started processing and printing B&W film in the wet darkroom. Seems that as more and more people come to photography via the digi-snapper route, they eventually become interested in that antiquated art form known as Film. I have said this so many times, have been cursed and belittled by some for my comments, but here it is again. Digital is not a replacement for film. It is simply another art form. There I have said it one more time. If you don’t get it, too bad. Get over it.

Now, back to the subject for today, how to get started processing and printing film in the wet darkroom. The question is, where and how do I start? What do I need? Is it hard to do? There are many answers to these questions. You can take a class, find a workshop, or study with someone that is willing to teach you. Or, my favorite method of doing anything. . . find a good book and learn on your own.

If you choose my method the next question is, what book? There are many good books on getting started with film. Also, there are a lot of good web sites on the Internet that will help you. My recommendation is to start where I did over thirty years ago. I found a great book that is geared to the rank beginner. This book does not outline anything that is set in concrete, but if you follow it you will process a roll of film and make prints. Wherever you go from there is up to you. This is where I started and I can say it worked the first time and though I do not use much of the techniques or materials in the book anymore, this was the launching pad for me to move to more advanced techniques. Some of the materials and chemicals are no longer available, specifically the chapters on color, but the basic B&W techniques still apply. This book is a bare-bones, get you started text.

OK. . . enough of my book review, time to get down to brass tacks. First I have to say that the book I recommend is long out of print. But, the good news is the title is readily available on the used market and it is not expensive. I found several copies on the Internet for $1.00! If you are interested in getting started in the wet darkroom, here is a good place to begin. It worked for me, I am sure it will work for you also. Here it is;

“DO IT IN THE DARK”

This is one place to start. . .

The dual grid, Variable Contrast Cold Light head (VCCL), is a great device for your enlarger if you print on black & white VC papers. These heads allow you to dial in any contrast grade your VC paper is capable of producing. You have continuously variable contrast at your fingertips. And, yes they do work. The trouble is, every paper is different. Setting the dial on the head to any random equal setting may or may not produce a grade #2 contrast. Worse yet, what two settings should you choose?

When you start using a new VCCL head you are now faced with a quandary. How do you calibrate this thing so you have some idea what paper grade you are actually getting? Did you know you can calibrate a VCCL head to a known standard? You can know what settings of the blue and green grid will give you an equivalent grade #2, or #3, or anything within the range of the paper!

Yes you can calibrate a VCCL head, and here is how it can be done. Look at the article “USING BTZS TO CALIBRATE YOUR VARIABLE CONTRAST COLD LIGHT HEAD” originally published in the Sep/Oct 2007 issue of View Camera Magazine in the ARTICLES area of our web site.

If you build you own darkroom sink or use a commercially available unit, you need something to protect the floor of the sink from scratches and abrasions. It has been a common practice to construct wooden Duck Boards for the bottom of the darkroom sink. These work well, they protect the sink, and allow water to drain, but wood is hard to waterproof and keep from warping.

I have heard of people using plastic lighting grids or plastic rods in the sink, but I have never tired them. I have constructed and used the usual wooden Duck Boards for years. Then I found something even better.

Dri-Dek® is sold as an anti-fatigue flooring for use in commercial work areas such as industrial manufacturing or commercial kitchens. It comes in 12” interlocking squares or rolls. This is a soft, flexible Vinyl that is perfect for the floor of a darkroom sink.

We installed Dri-Dek® in our sink two years ago and it has been an excellent investment. Water easily runs through and under the lattice work, it protects the sink floor, and it provides a soft, yet firm surface on which to work. Note, that the Vinyl does stain when exposed to some chemicals, like Amidol and Pyro, but it has remained flexible and I would not hesitate to recommend it to replace those old, warped wooden Duck Boards.

They say one image is worth a thousand words, or something like that. I have been asked numerous times to describe the making of some of my photographs. It is strange that I can remember a lot of the details of the moment. I can recall the feel of the place, and the excitement of being there in my mind’s eye. This coupled with my field notes detailing the date, time, and technical information, recreates a somewhat in depth story of the making of a photograph.

I have just started what I plan to be an ongoing project. I will take selected photographs and try my best to tell the story of how the completed interpretation was created. Hopefully there will be something of interest for everyone interested in all aspects of photography. Each installment will cover the making of one photograph, both artistically and technically.

I invite you to stop by the new “WHERE, WHEN & HOW: The Creative Interpretation” area of our web site.

Enjoy,

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.

To dry mount or not. . . that is a question? This debate seems to roll on forever. Sort of like Ford or Chevy? Is there really a correct answer? I have made my choice.

For me there is nothing that comes close to a properly dry mounted photograph. Once I made my choice, all I had to do was learn the process. I worked out a method that gives me what I like, and if you are interested in dry mounting your photos and have never learned the process, I have a little booklet that details my procedure.

This is not the only way, it is just my way. . . and. . . if you are interested, it is FREE!!! Take a look HERE for “DRY MOUNTING PHOTOGRAPHS” pdf download.

How do you identify sheet film? You put unique numbers on the film holder, but how can you identify which sheet of film came from any particular holder? You may be able to identify the film by taking notes and knowing the subject. But, what if you make several exposures of the same scene, say using different filters? How do you know which filter was used on each sheet?

We hit this impasse many years ago and I came up with a simple solution that has worked for us for years. All you have to do is file a notch code into the film loading flap. We have used this system to number over one hundred 4×5 holders. Want to learn how to modify your film holders? Take a look at “A QUICK & EASY SHEET FILM NUMBERING SYSTEM” for the details.

Hope you find this helpful. . .
