Casey Rocks the Brother ML100

Y'all probably know this feller by the name of Casey Neistat. YouTube blogger. Co-star of MTV's The Neistat Brothers series. Skateboarder. Drone flier. Father. Husband. New Yorker. A self-made person. He's doing well enough that he probably doesn't need me promoting his videos. But I've linked his Valentine's Day video above, a love-letter to his wife Candice, because it was sweet. And it prominently featured a Brother ML100 electric typewriter.

I liked the sound of the staccato rhythm of his electric Brother through out the video. And as a typewriter collector, I also like the idea that, for Casey, he's not a fetishist or collector. For him, it appears that an electric typewriter is just a practical tool. Like all the other practical tools that adorn the walls of his studio. That's cool, and refreshing. If I wasn't such a typewriter nerd and collector, and didn't like manual typewriters so much, I too might be happy with just one machine, a modern-day electric daisywheel "wedge".

I don't want to over-analyse Casey's video too much, but I liked how the typewriter, a not-nearly-as-glamorous-machine-as-a-black-and-chrome-manual-from-the-1930s, was the perfect tool for writing a love letter, which he then folded and placed in an envelop. He could have - if he had a printer - word process the crap out of a love letter. Or pen it by hand with quill and bottled ink. Unless his penmanship, like mine, is sorely lacking. Typewriters were made for people like us.

Casey's video, I'm certain, will garner millions of views. And those millions of people will be witness to the eminent practicality, in 2018, of a typewriter in one's home, office or studio, a tool ready to do the work of printing directly to paper a brief document, like a love letter.

Perea Nature Trail Hike

Rio Salado and White Mesa


Post-Script: These images were digitized via camera, rather than using my scanner, which hasn't been performing as well as it used to. I suspect I need to clean the optical sensor and the glass, at the very least. These paper negatives were also semi-matte finished, so weren't as sharp as glossy negatives. Lots of dust spots to contend with, too. Fun.

I know that I eventually have to get back to shooting black-and-white film, rather than merely paper negatives; but I've been shooting paper for so many years (since the mid-1990s?) that it's hard to change old habits. Of course, with film that means lengthy drying time in the drying cabinet. And then the problem that I'd need to rig up a back-lit copy stand, to digitize the negatives via my camera, with even more problems with dust; but at least the tonal range would be improved.

There are some scenes in northwest New Mexico that look like they could be from another planet; or from another era. Volcanic cones, ancient geological upheavals. I've got to get out and explore.

Further Thoughts on Lumen Photography

Winter Ash Tree

Pre-wetted with water, lens wide open, 3 hours 45 minutes exposure.

I've been consciously trying to make a lumen print every free moment I can. These aren't as quick as snapping a shot on a phone, or even hitting "print" on the computer. It takes many minutes, usually several hours in fact, for the image to form itself within the little paper camera upon the slip of photo paper inserted within. Even then, the image isn't ready to be shared. It has to be digitized, then post-processed into a positive.

When a camera can make an exposure in a minute fraction of a second, quicker than you can blink, you can't help but question the value of your participation in the process. Sure, you pointed the camera and chose the moment to press the button, but that's about it; all the magic happened in milliseconds of time.

But when the image takes literally hours to form, and even then is still in "raw" form, requiring further interaction, you can't help but think that here's a process you can get your head around. It's participatory, from deciding where and how best to set up the camera so it won't be moved or disturbed for several hours, to preparing the photo paper and loading the camera, to carefully setting the little box so it's pointing in the general direction you intended. And then the waiting, setting a timer and periodically checking on the camera to make sure it hasn't fallen over, worrying over it like a momma cat over her kittens, hoping the composition is right, hoping the light will be right, anticipating the results yet knowing, down deep, they won't be as good as you'd hoped.

All of this fussing, the extended exposure time required, fools you into thinking you're more involved in the outcome than you really are. It's still a matter of pointing the thing in the right direction, then opening the shutter to let light inside. The magic happens, not as a result of your cleverness, but despite our best intentions. It's the physical process, photons upon molecules. The trick to art, it reminds us, is in convincing others we're somehow responsible for the outcome.

For many years I was an avid pinhole photographer. I was attracted to the primal simplicity of the idea that light can form an image by mere projection through a small aperture. Yet, for the image to be fixed, some complicated process has to unfold, whether it be the chemical processing of silver gelatin film or paper, or a digital sensor. The only difference being the type of lens employed.

Once I'd discovered for myself lumen photography, another kind of primal process became apparent. The magic for me is more apparent than with pinhole, where the distinction is merely in the kind of lens employed. Here, the lumen image is due to the direct action of photons upon a silver gelatin emulsion. It's self-forming, it's light itself doing the etching, no further human interaction required except in the post-production phase, where the necessity of making the image a positive is more due to the inability of humans to directly appreciate negative images.

Lumen prints are developer-less, not like Polaroid prints, where the developing process seems invisible but is merely built into the print itself, a chemical pod squeezed between rollers as the print is ejected. The lumen process seems more like an act of nature. You boil down cattle bones, mix in some silver salts, spread a thin coating on paper, stuff it in a box and focus light upon it and, as if all by itself, an image is formed. Of course, in actual practice we usually let others do the boiling of bones and coating of paper, like Ilford or other manufacturers of photographic papers. Still, there's an element of mystery involved, as if to remind us that magic is built into the very fabric of the elements, but which we commonly dismiss under the rubric of "chemistry".

Silver nitrate or potassium nitrate? One makes images, the other blows things up. We get to choose. I am reminded of Alfred Nobel, the namesake of the annual peace prize awards, who was also the inventor of dynamite. In my mind there's this double-exposure formed, one layer being lions lying with lambs, the other layer crater-pocked fields in France, the smell of cordite, the broken minds and bodies of young men.

Photography, as it has advanced in technical sophistication over the centuries, begins to resemble as much the nature of potassium nitrate as it does silver nitrate. We aim guns; we aim cameras. We take a shot; we take a shot. We capture prisoners; we capture images. It takes a conscious effort of the will not to use the language of warfare when discussing photographic creativity, that's how ingrained these terms have become in the common lexicon of culture. It's all too easy to say "I've taken a picture," when you really mean you created a picture. Taking sounds like appropriation, winner take all, the business of empire-building, losers left in the wake. Creativity, I'd like to think, should be a collaborative process, a making of something beautiful, where once there wasn't an image, now there is, ex nihilo, as it were, being made in the creator's image; or, at least, symbolic of such.

Lumen prints appeal to me also because they remind me of the very formative years of photography, obscure and difficult processes requiring lengthy exposures and still subjects. You couldn't make a lumen print of a quick-action sporting event, for example, unless the intensity of your light source was on the order of a nuclear detonation. I'm reminded of a supposedly true story told in John McPhee's book The Curve of Binding Energy, where a nuclear physicist (Ted Taylor, if memory serves me), observing a nuclear test, set up a cigarette in front of a small parabolic reflector and, shortly after the pikadon - Japanese for "flash boom," he reached down and took a drag off the smoldering ash. You could do that today with a magnifying glass aimed at the sun, but it would still take many minutes or hours in the same setting to capture a lumen print image of the scene.

Darkroom photographers have known for a long time that a clipping of silver paper, left out on a table will, over time, slowly turn a subtle hue of pink or purple. But to employ that phenomenon into a usable photographic process requires fast optics, to record the image with a semblance of convenience. If one chooses a large format camera and lens, the main limitation is the maximum aperture available on standard large format lenses. The fastest optic I have available in a conventional large format lens is a 127mm Kodak Ektar lens from the WWII era. F/4.7 doesn't sound all that fast by today's bokeh-obsessed standards, but it's barely adequate for the process. Since sub-second exposure times aren't necessary for this process, having a lens with an integral shutter isn't necessary. Still, finding a lens with adequate image quality that projects a large enough image circle is no small task. I also have a Fujinon Xerox machine lens, of f/4.5 aperture, but it requires a paper size of at least 8" by 10" for a normal angle of view. Smaller lenses, like magnifying glasses, will cover the 4" by 5" format better, but being of a single-element meniscus design, exhibit severe off-axis aberrations.

I've found such improvised optics seem to work well with the lumen process only because the resulting images, with their blurry edges, have a dream-like quality in keeping with the ephemeral nature of lumen photography. A sub-f/4 lens from a medium format camera, if one could be found, would be ideal for creating sharper images, if that were one's goal.

I first became aware of lumen photography from artists who were employing pinhole cameras to make exposures of the sun's path across the sky using exposures lasting many weeks or months. It was only because of the work of photographer Jorge Otero, from whom I acquired a Lumenbox kit camera, that the possibility of scenic landscape lumen photography became evident. Otero, who goes by the social media moniker of Joterman, began using fast, single-element lenses with photo papers, while also pioneering the technique of pre-wetting the paper with water in an attempt to speed up the image capture effect.

It's exciting to be at the pioneering phase in this process, reminding me of what it might have like in the early 18th century when photography was first being developed. Much has yet to be discovered about how to speed up the image-formation process. I've thought about running a series of experiments involving dousing pieces of photographic paper in various household liquids to see what results. Coffee, ketchup, hot sauce, soy sauce or bleach - what might they reveal? Probably a huge mess. A liquid-proof camera seems necessary, at the very least.

Lumen print photography, involving fast lenses to create pictorial images, is a process that could only have been practical within the last few decades. Given the resulting negative's ephemeral nature - the prints remain light sensitive and hence are continually at risk of fading from subsequent exposure to light - they require digitization through quickly scanning or photographing with a digital camera, after which the resulting image file can then be post-processed, by inverting the tones in photo editing software, to create a file that can be digitally printed. It's an intrinsically hybrid process, which represents a fundamental irony, given the primal nature of the processes involved.

Taking a first brief glimpse at an exposed lumen print under subdued lighting is always accompanied by the expectation of a fresh discovery. No two prints are the same, while the color palette of the negative itself is often more pleasing than the hues resulting in the reversed positive digital image. I'd like to try inverting the monochrome portion of the image to create a positive rendition, and superimpose that with the tones present in the original negative, using the layers tool in a program like Photoshop, to create a hybrid positive/negative version. Or perhaps some semi-reversal chemical process, like solarization, might be found practical.

I've also found the resulting image can vary widely, depending on the intensity of the scene's illumination, the color of the subjects, and the exposure times involved. Pre-wetting with water also changes the color palette somewhat, while in my camera also results in the pooling of water near the bottom edge (the image's top), resulting in globs of dark tones that adds to the mysterious outcome.

I have a cobbled-together 8" by 10" format sliding box camera (employing one box nested inside another for focus), that's currently fitted with a single element meniscus lens. Perhaps I should rig up that fast Fujinon Xerox lens and see what transpires.

I'll be sure to share my results herein, and on my YouTube channel.

Winter Light

Tree001 (1)

I was inspired this morning to take the little paper Lumenbox camera outside today and try my hand at another exposure. The camera had been sitting on the lid of my scanner for several weeks, quietly eyeing my activity at the cluttered desk, waiting for its time in the sun (literally). Not that it's actually conscious, but sometimes we just have to pretend. It's part of the process, anthropomorphizing our creative tools like they are more than mere helpmates.

Once again I used a piece of photo paper that came supplied with the camera by Jorge Otero, but this time I pre-wetted the paper with warm water. Wetting the emulsion speeds up the exposure somewhat, while also causing slightly different colors.

To limit the paper's exposure to the cold until I was ready to begin the exposure, I first went outside and hunted around for a suitable composition. Wintertime can be difficult, with it's barren tree branches and sparse vegetation. Well, technically it's not yet winter, but close enough. I ended up setting the Ultrapod at the base of a backyard tree, with the wooden camera platform pointed almost directly up the side of the tree trunk. Then I went inside, wetted the paper and loaded the camera, then quickly got it set up on the tripod and began the exposure. I set the dive timer dial on my Casio watch and went to work editing today's video, forgetting about the Lumenbox until an hour and 20 minutes had passed.

I was surprised at the contrast and density of the resulting image, which pleased me. There was a bit of a dark gray stain on the reverse side of the paper, from the wetted paper affecting the black craft paper liner's dye inside the camera. I brought it inside, quickly dried the remaining few spots of water off the paper (it would have been entirely dry if this had been a summer exposure), then sequestered the negative in a black paper storage sleeve until I could scan it.

I like to minimize the amount of light these negatives receive after their in-camera exposure. I warmed the scanner up and did a pre-scan, before bringing the negative out of its storage sleeve and doing the scan. Being as I currently lack a real photo editor like Photoshop, I invert the tones on the Mac Mini using the preview mode (reversing the left and right controls of the levels tool), then imported the image into the Photos app for final processing, which required a bit of contrast and levels adjustment. The colors also reverse with the tones, resulting in this green-tinted image.

One of the things that really surprises me about this process is the final color pallet. Even comparing images made mere hours apart, the results can vary considerably. This is the first time I've had this greenish tone, which contrasts nicely with the delicate salmon tones to the sky, and the cyans near the edge. The dark spot near the top edge is probably the result of the residual water having ran down into one spot near the bottom of the negative (in-camera images being reversed vertically).

This is a very satisfying result, and one that makes the process so enjoyable, the anticipation of what might happen, but not knowing exactly what. I'm also pleased knowing that it's very hard to over-expose these images, because as the image slowly forms on the paper within the camera the darker image areas self-mask.

I used the lens with its aperture wide-open, resulting in those wonderful out-of-focus areas along the left edge, a result of the intrinsic optical properties of the single-element meniscus lens.

During these cold months my garage-based darkroom requires concentrated planning to use effectively for chemical processing of film or paper, as the space has to be heated and the chemicals microwaved to room temperature. Therefore these impromptu self-forming lumen prints are a wonderful diversion from winter's chill.

Testing the Lumenbox

Lumenbox Camera

Post-Script: This first image was 1/2 hour exposure in morning light with the aperture stop in place. The image was rather faint on the paper negative, but after digitization the tones were expanded in software using the curves and contrast adjustment tools.


Note the interesting colors. The cyan tones on the trees appear almost realistic, and the sky in the upper left corner resembles the martian landscape via NASA imagery. Reminds me of an artifact from my formative years in the 1960s, when many Americans still only had black-and-white television, of a colored plastic overlay attached to the screen, that had three color zones, blue on top, brown in the middle and green in the foreground. It looked eerily realistic for certain televised baseball shots of the infield.

This next image was taken this afternoon, in my front courtyard in brighter sun. Another 1/2 hour exposure, this one minus the aperture stop, so the lens was wide open and hence producing a slightly softer image.


Given that the courtyard walls are sand brown colored stucco, there is a certain eery resemblance to reality here.

Making lumen print images is a fun hybrid process. Making the paper negative requires little else but time, no additional chemical processing needed. Like a slow negative polaroid without the chemical pod. Most of the work is in post-production, where you can apply your creative vision to the tonal curve in order to get the contrast to your liking. The colors kind of fall where they may, as they are an inversion of the negative's original tones, appearing on the opposite side of the color wheel spectrum.

This process isn't really complete unless these images are printed in delicate color tones upon textured art paper via digital printer. Since I lack such a printer, that will have to wait for the future.

Another Ultra-Portable Joins the Fleet

Smith-Corona  Cougar

Post-Script: If you're a collector of small typewriters, there's a tradeoff to consider, that being build-quality and typing action versus portability. There are only a few ultra-portables that come close to the same user experience as a medium-sized portable. But by limiting yourself to that small collection, you will miss out on the larger world of ultra-portables; which implies that such a collector must accept the limitations that come with these diminutive writing machines.

I've accepted long ago that I like the build-quality of many Brother machines, yet all the ones I've used suffer from a heavy touch. I accept that as part of the owner experience. This Smith-Corona is no exception. It does have a flimsy feel, far different from the Olympia SF, for example. Yet it's much lighter than the SF, while also noisier in operation. It goes with the territory.

I like that my collection of small typewriters are so easy to store, and each fits in a messenger bag for mobile typing, ideal for the restless word wrestler.

Here's a video I made about this typewriter. Enjoy.
