Laziness is the mother of efficiency

In my last post, I briefly mentioned I don't do much in the way of test strips. I don't like doing them as it takes time, and more importantly, wastes paper, and quite frankly, the less effort I have to make the better. And at a buck a pop for a sheet of 8x10, (yes, Foma is expensive, but gorgeous), I hate wasting paper.

Instead, I make work prints, one sheet per negative, without bothering with a test strip at all. How do I do that? Well, I'm no darkroom guru, reading my negative and knowing just what exposure it will print at. You need to spend a few years slaving away in a commercial lab, day in and day out, making prints, to get to that stage. For us amateurs, there is an easier way, an enlarging meter.

I have this nifty gadget from Darkroom Automation, which allows me to do wonderful things like profile my paper versus my negatives and stuff, works as an enlarging meter and a densitometer, but I'm lazy. I use it to simply give me a base exposure which allows me to pop out a work print in one go. I measure the darkest tone, which gives a value in stops. I compare that to my base negative (one I've printed with a full range of tones and a known exposure time and value for my paper) and calculate the difference in exposure. Using that, I can pop out a work print, usually with a reasonable exposure (at least as a starting point to fine tune from) with just one print. If I want to also factor in contrast control and dial in the right amount of magenta, I can also measure the lightest tone, and with the difference between the two, (compared to my base neg/print which I measure all against) I can dial in the contrast too.

It does involve using a calculator as I might need .67 of a stop less exposure, but I'd rather use a little time than waste paper, and do things only once. Thus, other than determining that first exposure for my baseline negative, which I do test strip, to get a baseline exposure, I don't bother with test strips at all. Unless of course, some bastard at the darkroom changes the enlarger bulb on me. At which point, I usually have to do it again. Now, bear in mind, I am using the same enlarger all the time, and if you use more than one, you would need to do a test with each one to get your baseline exposure for each.

I'm all for making your life simpler with handy gadgets that actually work.

F-stop printing

I wanted to share a darkroom technique that I use when I print that not many people seem to know about. It's called F-stop printing.

Now, this isn't something new, it's been around for a long time, but it's not what we are taught in school or in many photography books. When I was taught to make test strips, we'd make them based on multiples of seconds. So start at say 5 seconds, the next bit would be 10, the next 15 etc. I personally find this to be rather inefficient.

Instead, I do my test pieces (which are few - but that's another post) based on using stops. Just like when you factor in stops when you shoot, you can factor in stops when you print. A stop more is doubling the light, a stop less is halving it, regardless of whether you are exposing film or paper. So to begin, I'll pick a starting exposure in seconds based on a best guess, knowing what my paper, aperture etc tends to go with. For me, 10 sec to 20 sec, which is one full stop by the way, tends to cover my average negatives, and makes for easy calculations. This will be different for you and depend on your paper, your negatives and what aperture you choose. I use a very slow paper, Fomatone, which is a full two stops slower than Oriental for example, and commonly print at f8, if you are curious.

Next I simply divide that one stop range into quarter stops, so you get 10 sec, 12.5 sec, 15 sec, 17.5 sec and 20 sec. Now, someone is likely to pipe up at this point, that these aren't exact 1/4 stops, which is true, but they are close enough and a simple extra 2.5 sec from my starting time. If you want real quarter stops, from 10 to 20 it would be 10/11.9/14.1/16.8/20. See the unblinkingeye.com link below for a chart if you are picky. While I am very exact with measuring chemicals, 0.7 of a sec at this point isn't a big deal.

I then expose the test piece or strip accordingly. When I take a look, I can see which is closest to the exposure I need and since it is all roughly quarter stops apart, I can very accurately, off that one strip, pick a good exposure. No guessing, or fiddling around with a few more seconds, here, or a few less, taking several tries to get it narrowed down. Now it can be pretty close and sometimes hard to tell the bits apart, but you can always make it thirds or half stops, whatever works for you.

F-stop printing also helps when it comes to burning and dodging, as it makes things easier to decide. You can burn or dodge half a stop, a full stop etc.

Here's some further info to take a look at, including a couple of manufacturers of F-stop enlarger timers, which are on my wish list.

If you own Tim Rudman's The Master Photographer's Toning Book, (a previous post) there's a chart in the back. If you don't, what the heck are you waiting for?


Give this a try the next time you print. You might be surprised at how it simplifies things for you.

Why bromoil?

I'd like to tell you a story. About why I love to do bromoils. I had a wonderful chance to see a fantastic exhibit of pictorialist photography here in Vancouver, a couple of years ago. It was the TruthBeauty exhibit at the Vancouver Art Gallery. Pictorialist photographs from about 1835 to 1945 were on show and they were fascinating. The premise of the pictorialists was to use photography to create art, not simply record what they saw realistically, but what they envisioned. Many different printing processes, now called alternative processes, were used to produce fantastic works of art. I fell in love. The images, the visions expressed, the interesting printing methods, all spoke to me of what photography could be. And in our digital age, so much of photography ends up seeming the same in the end, an exact as possible realistic rendering that all blends together after you've seen so many.

One process in particular stood out for me. Bromoil printing. I had to find more out about it. To give the short answer, bromoil involves bleaching a black and white print, and then stippling on layer after layer of ink to bring it back. You can achieve a wonderful etching like quality to a print that has a luminous depth or even a highly photographic style rendering, depending on your technique. It offers a great deal of control over your print, creative freedom in producing your print, and the satisfaction that comes of handcrafting something beautiful.

I love the unique look of a bromoil print. For me, the prints have a different feel to them. They produce an emotional response beyond just the subject matter. I love the historical connection. I am using a process that is over a hundred years old. My teacher learned from masters of the process and there is this long unbroken line of learning stretching back into the past. Also, wonderful historic processes used with modern photography allow us to connect directly with the past, something that is lost so often in our high tech digital world. 

Crafting your photograph in general, directly making the print by hand is a tie to the past that digital technology has robbed us of. Creating images this way allows us to appreciate the beauty of something handcrafted, another castoff from our mechanized age. And the rarity these days of these processes, of handcrafted works of art in general, especially with photography, allow us to create something that truly is unique.

If you'd like to see some prints, I've posted some of my images earlier. This is the link

Second group show opening Saturday in Vancouver

Awesomeness. I have managed to get two images accepted to a second juried group show here in Vancouver. This is pretty exciting for me, as these shows are my first attempts. The show opens this Saturday, Feb. 5th at the Vancouver Darkroom Co-op Gallery. You can pop over to 652 Kingsway (at Fraser St.) for the 7pm opening if you are in town.

If you can't make it, here's a preview.



If you're wondering what this is, its the remnants of a shipwreck, the Peter Iredale, on the Oregon coast. These are lith prints on Foam Chamois fibre paper, beautiful creamy coloured paper that for Foma, gave me some wonderful, subtle colours with the lith process.

Are you also wondering what the heck lith is? Well, its a black and white printing process where the paper developer is based on lithographic film developer and the combination of papers and developer chosen can give you a wide range of colours. The basis of the look, besides colour, is great detail in the highlights and gritty blacks. The fun of it comes from substantially overexposing the print under the enlarger, (this controls the highlights) and leaving it in the developer until the blacks reach just the right point and immediately tossing it in the stop bath without waiting for the print to drain. You do this as the blacks develop through a process called infectious development where they start off slowly and the development speeds up exponentially as you go. If you were to leave the paper in the developer til completion, the image would go completely black because you have overexposed it an average of 2-4 stops. So you have a minute time frame to choose just how you want the print to look and your never quite sure at the start how it will go. 


This is just one of the wonderful things I love about darkroom work in general. Creative, fun processes that always have a lovely element of surprise waiting to be discovered.

See you on Saturday.

Sources for film and darkroom supplies

If you love printing in the darkroom as much as I do, finding a reliable source for supplies including film, paper and chemicals is pretty important. Here in Canada, its pretty limited. If you are lucky, you may have a local store in a large metro such as Vancouver, that carries some stuff. If not, mail order it is, and depending on what you want, may be hard to come by.

For local stuff, I use Beau Photo now and then. A lot of the paper and chemicals I use they don't carry. Now, they tell me they can special order it in, but it'll take a month. If I need it in a week or so, that won't really do. But they are the best source locally for the widest variety of things overall. Another option in Vancouver that still carries some stuff is Lens and Shutter on Broadway. You won't find it on their website, but they still have some stuff in store.


Canadian mail order is not something I've done much. Here are some options you can try though.
The Camera Store in Calgary
Darkroom Central in Winnipeg
The Frugal Photographer in Calgary
Henry's in Toronto


Now for myself, I live within a short hop of the border and my preferred order spot is Freestyle Photographic, down in California. Fast service and the largest selection, as well of course, good prices. A pretty good source for the more esoteric stuff too.


Other options in the US include
Photographer's Formulary in Montana - large selection of bulk chemicals too
Digital Truth in Texas - also manufactures EcoPro environmentally friendly chemistry
Calumet Photo in Illinois


Have fun printing!

New Lith Prints

I've made a set of 4 lith prints recently, as I wanted to submit them for the Vancouver Darkroom Co-op call for entry for the latest exhibit. This is the first time I've submitted work for a juried group exhibition and in fact, for the first exhibition at all. I've haven't found yet whether they'll be accepted, but we'll see how it goes.

Creating a set or series of images is something that I've not done much and I suspect that's the case for many photographers. Unless you have a specific project in mind, it's not something you may think of. As an exercise, this is something I'll be trying the next time I go shooting and you might want to think about it too. When I see something that really catches my eye, I'll either look for similar items that I can put with it as a theme, such as close ups of flowers framed the same way or multiple shots from different angles and views of a single plant for example. Another option would be images of related items that can make a theme such as shadows or reflections. As long as you can shoot them in the same style, you can relate the images. Shooting with at least three or more images together will get you enough to at least do a triptych.

These images are of the Peter Iredale, or at least the remains, of a shipwreck on the Oregon Coast. I tried a new paper, Fomatone Classic Cream base Chamois finish paper. The fibre based paper is actually a very deep cream colour, almost a light beige. It has a nice, lightly textured finish and with the lith chemicals I use, Moersch Easy Lith, has nice subtle colours, at least for Foma paper. You'll have to excuse the lines, my scanner is not doing too well these days.

With ink and a brush

I just got back from a 6 day workshop on how to do bromoil prints. For those unfamiliar with this alternative process, you take a black and white image, bleach it back, then while damp use said ink and brush and carefully stipple on ink, layer after layer, and where the silver was in the image, it now takes ink proportionally, and you build back the image in ink.

It's a wonderful process that gives you a great deal of control and creative freedom on how you create an image. Depending on softness of ink, your technique, brushes etc you can control how grainy you want the image from a coarse lithographic style to a very fine grained photograph. You control density by deciding how much ink should be deposited, and you control how much you want the highlights to stand out. Contrast is also something you control in the final image. It's a technique that lends itself to sensitive interpretation of a subject beyond just what the camera records.

The instructor, David Lewis is one of the few remaining masters of this process and an excellent teacher. He's also quite the character and keeps the workshop entertaining. He gives workshops primarily down in the U.S. If you are lucky, try and get in on one down in Arch Cape, Oregon.

It was gorgeous there, right down on the beach. Our host was Linda Lapp Murray, who is a wonderful lady and fantastic photographer. Arch Cape is near Cannon Beach, but a bit off the beaten path, so the weather was great, scenery gorgeous, and it was quiet and peaceful.

Here's a few examples from the workshop as well as a couple of pictures of Arch Cape.

Toning black and white

Many people may not realize but traditional black and white photographs are frequently processed with toning chemicals. Some cause very little colour change, perhaps only improving the contrast a little and are used mainly to increase the print's longevity and archival qualities. Others do produce a distinct colourization of the print, from a gentle warming of the tones to a sepia brown or cold blue colour and many others as well. Toning is very much a subjective process, based in the end on how you want the print to look as much as anything else. It is another process where experimentation can yield endless results as various papers, development and toners themselves cause a myriad of responses.

Tim Rudman has written one of the most comprehensive guides to toning and this book, unfortunately has long been out of print. Lucky for us, Tim has managed to have his book reprinted and it has just been released. The Master Photographer's Toning Book covers materials and processes in great detail.This is a limited print run, just 1000 copies and is available here from Silverprint in the UK. You can read more information at the website for the book. http://masterphotographerstoningbook.com/ Copies are selling briskly so make sure to get yours.
