Gallery Updates

It’s been a long time since I updated the gallery here. In that time I’ve made quite a few new prints and remade a few from earlier on different paper or enlarging equipment.

So, the gallery has been updated accordingly with lots of new photographic work. Enjoy!

A restart, and updates

The good news is, I’ve not been idle in the photography department. The bad news is I’ve not been idle anywhere much else, either!

So what’s been going on, anyway, besides the rust and peeling paint?

Printing. I’ve done a lot of this, which is great. My earlier described LED lightsource has been a faithful servant and combined with primary green and blue cinematic filter gels under the lamp, I’ve made a number of pleasing split grade prints.

LED. The bigger news is that I’ve been working alongside a UK-based hardware engineer and darkroom printer to develop a complete controller and lightsource system using red, green and blue high LED modules. This allows full control over contrast grade, and a completely paper-safe view of the projected image when not exposing. It’s still in prototype stage, but well on the way to being completed! I started out with a prototype made of cardboard, using the existing condenser system, but have since rebuilt it in a wooden box and switched over to running it as a diffuse light source. This has been my primary printing method for a good year and a half.

Liquidol. I tried a bottle of Formulary Liquidol for my printing. As it turns out, the working solution, long lived as it is, still wasn’t long lived enough to deal with my somewhat sporadic darkroom efforts. Liquidol is a lovely developer, but better suited to a more regular throughput, or for darkroom users who don’t print often, but do long sessions with many prints when they do.

Ansco 130. My original working solution, mixed from powders in September 2013, was still active as of this June, last time I printed. I’d been replenishing it every session from full strength stock, but that ran out some time ago. I will be getting more, this developer is perfect for how I work!

Cameras and formats. I got into the Pentax 645 system, and use that camera almost exclusively now. With a 45, 75 and 150mm lens, a couple of filters, 3 film inserts, and some closeup filters, it’s a very complete system which has been giving me great photos in a wide range of situations, from shooting landscapes on a tripod, to handheld shots at an air show. I’d love to add the 300mm and 35mm lenses to the bag, and replace the original manual focus 645 body with a newer 645N which has much better ergonomics. But it’s a solid, reliable system I’m happy with. I still have the Yashica TLR, along with a 1936 Voigtlander Brillant and 1926 Ansco Goodwin box camera, all in medium format. In 35mm, I still have the Canon F1 but don’t shoot it much. My old Vista View 35 plastic camera had a shutter failure. I found an Olympus XA, which for a couple of years was the only reason I even shot any 35mm at all; sadly, a couple of months ago it had a (common) electrical failure in which the self timer cannot be disengaged. A 10 second shutter lag means the camera is of no further use to me for the type of shooting it excelled in. Sadly missed. I also found a Canon EOS Rebel X with 35-80mm mk.III kit lens, it’s a good little camera and might yet vie with the F1 for the “smaller, faster” type of shooting. I just don’t do that much, though. And I MUCH prefer handling medium format film, both for scanning and enlarging.

Large format. Ha, fooled you! I have not, yet, succumbed to any urge to go to 4×5 large format. But I do have a plan for how I might upgrade my enlarger for it. Just in case, you know? Only the Pentax 645’s overall competence is saving me, I suspect.

Move. In July, we moved home, and so the quest to make a regular room into a working darkroom is on, again. It’s taken until now just to get the room habitable again, but plans are afoot for darkroom use. I do indeed plan to document this process right here.\

Fiber and other art papers. I took the plunge into printing on fiber base paper and it wasn’t as scary as it sounded. Adox MCC-110, Ilford MGFB Classic (glossy) are very nice papers which dry decently flat without much extra effort beyond hanging them up for a couple of days and then flattening them under something heavy for a couple more days. My favorite, however, is Ilford’s Art300 cotton rag base. Takes less washing, has a pleasing eggshell/semi-matte finish which manages to combine both high DMAX and easy retouching (diluted India Ink for spotting, can even scrape off emulsion to remove small dark spots, can use pencil and colors easily also. Washing FB papers has been in-tray, by multiple changes of water, one print per tray. I’d still like to make some sort of washer, but it’s not critical.

Gallery. I’ve been printing, which means I have updates for the gallery to follow shortly.

Digital. We (as in my wife and I) finally replaced the ageing and much-dropped Olympus with a “proper” digital camera – a Sony SLT-A33. Uses the existing Minolta A-mount lenses she had, and the SLT cameras play well to the strengths of digital in being able to live-view focus at 100%, and preview the exposure and DOF in the viewfinder. As much as I love film, and manual focus cameras, our grandkids move too fast for me! Also, I do like color print film’s tonal characteristics, but it’s kind of a pain to deal with when I just want some competent snapshots, or if I find myself shooting an event of some sort (which has happened a handful of times).

See, I’m not just some film-only elitist snob! I’ll shoot digital when it makes sense to, we just didn’t have any digital camera that was up to doing it properly until the Sony.

Anyway, thanks for reading, and my sincerest apologies for the long break. I plan to write more here and use it as my primary place for sharing my photographic work.

Drying Marks BEGONE!

One thing which has been the bane of my existence since the first roll of film I developed at home is the dreaded drying marks. Those irritating little streaks on the base side of the film.

Hanging to dry

I don’t, oddly enough, have trouble with drying marks on my prints.

I’d tried everything. Lots of photoflo. Tiny amounts of it, just a drop. Squeegee/no squeegee. Sometimes I would be streak free and home clear, but more often than not, there they would be.

They do wipe off easily in my case. But I’d still prefer not to have to deal with them.

I don’t recall where I read this. Maybe FADU or APUG. But someone suggested distilled water for the final rinse, with just a drop of photo flo. I usually have that around anyway as I use it for mixing my stock solutions and diluted developer working solutions.

Whaddya know but it worked! Half a dozen rolls finished up this way, sitting in distilled plus a drop of the wash aid for a few minutes, and not a single drying mark among the lot of them! No squeegee either, which reduces the chances of damage. Win win, as they say.

So if you’re fighting this problem and are at a loss for how to fix it, this might just be the answer!

Next trick will be to see if I can get away with just plain distilled water and no photo flo at all. I’ll be sure to post how it goes.

Off-the-shelf LED Enlarger Lightsource – part 3: contrast, exposure and coverage comparisons

In part 1 I considered ways to use a standard LED light bulb in place of the PH140 and ended up with the Utilitech Pro from Lowes.

Part 2 saw me cobble together a vaguely alarming cardboard-and-hot-glue contraption to hold the bulb in the right place.

Finally I made some comparison exposures to test for differences. I expected to see longer exposure times as the PH140, an overdriven 75W incandescent, pumps out 1150 lumens compared to the Utilitech’s 60-watt equivalent 800 lumens. I hoped for equally good coverage. I knew I’d see a change in contrast but honestly had no idea what to expect there.

Coverage

Though it certainly looks good by eye, the only way to know for sure is to make an exposure of an empty negative holder using each light source and compare them. I aimed for a mid-to-light gray with no contrast filters, which turned out to be about twice as long for the LED, all other settings the same. I set up for 6×6 medium format as my 80mm is not necessarily designed to cover larger frames.

This is how it appears on paper, with both tests scanned together for a direct comparison:

ph140-vs-led-coverage

Not bad on either one; just a tiny amount of visible variation, if anything the LED looks a little more even! Ignore the blotch in the top left of the LED patch; that’s a thumbprint from slightly sloppy handling.

Next, some post-scan curves alchemy, slamming the white and black points toward each other so that the exposed patches are represented by the full available range of tones. If there was such a thing as grade 50 paper, it might look like this:

ph140-vs-led-coverage-boosted

Blimey! So, the LED has a hot spot in the middle and falls off quite evenly toward the edges. Some of that might be down to the longer path taken by the light exposing the corners here; this was a 4×4 inch patch, the enlarger head nearly bottomed out, so I’d expect some falloff in the corners under the circumstances. The PH140’s light spread is weird and awful looking, with very sudden and severe drop off into the corners, though the center isn’t quite so hot as with the LED! LED for the win, folks.

Again, keep in mind that’s a highly exaggerated contrast level and that the first pair of patches are really what it looks like. In real prints even the PH140’s oddball coverage, which is just discernible in the unmolested scan, does not make any noticeable impact. So the LED? It’ll do just fine, thank you. I should probably be edge burning my prints anyway, which would only serve to cover up the slight loss of light in the corners.

Exposure and Contrast – Grade 2 filter

Next up, a comparison of the two light sources through a grade 2 Kodak Polycontrast filter. This will give me a feel for how exposure time and contrast selection would differ. Again, both prints were scanned together, so the tones on one compare directly to the other.

ph140-vs-led-exposure-contrast

The differences are fairly clear: the LED needs longer print times and has considerably lowered contrast. The longer time is about what I expected. Looks like highlights start coming in about 2/3 of a stop slower than with the PH140, somewhere between 8 and 12 seconds for the LED vs 6 seconds for the PH140. Since I’m about to start using Adorama VC RC and the new Ilford FB Classic papers, both of which are faster than the Ilford MGIV, I could actually use that slight increase in times.

The massive change in contrast through the #2 filter is rather unexpected. Now, since I’m moving toward split grade printing using blue and green filters, this may not matter too much, but it’s an interesting data point. I haven’t formally tested unfiltered exposure, but did make a couple of contact sheets that way and they looked to have normal contrast.

My next move is to subject this setup to some real-world abuse by making prints. I’ll find out in a hurry if there are any significant shortcomings.

Off-the-shelf LED Enlarger Lightsource – part 2: a custom lampholder

In part 1, I explored options for a cheap LED-based enlarger lightsource and settled on a 60 watt replacement, off-the-shelf bulb which looked promising.

However, there was no way I could use the existing lampholder for this. I needed to come up with something to hold it firmly in a position which would work for the purpose.

As is often the case with such prototype, cobbled together designs, I chose to work in the easiest possible media: cardboard, hot glue, acrylic paint and duct tape!

Be aware that this is a project involving line voltage electrical components and is built on the assumption that nobody will EVER be stupid enough to try running something like a 60 watt incandescent in it. If you aren’t comfortable or competent working with things which will connect to typical household 110 or 220 volt outlets, don’t even bother; it’ll hurt you, or worse, if you don’t respect it.

Anyway the build process is best described in pictures.

Position of the standard PH140 bulb. Clearly this is not too critical; my example is a bit off-center. My LED bulb has a wider frosted area facing down, so my main concern is proper fit and the correct height above the condenser.

The box, a fairly thick-walled 6x6x7 inch affair, will provide ample space for the design I aim to implement here. It mounts atop the enlarger lamphouse using a hole I have already marked up and cut. There's sufficient clearance to allow the enlarger head to move the full length of the column.

I needed a platform on which the lamp socket could be mounted. Careful measurement of the original lamp holder, PH140 bulb, and the new bulb, suggested a level where this needed to be positioned. It's very thick cardboard cut from the box my enlarger arrived in, initially held in place with nails pushed through the outside of the box. The large opening will have a thinner piece of mat or illustration board, cut with vents and a hole for the lamp socket to mount up. This will allow a bit of fine positioning before securing in place.

With the new lamp holder in place, the LED bulb location is close to the original bulb. Height is correct, and it's probably better centered than the PH140 ever was!

So there you have it. In the final part of this series, I’ll test the thing to make sure it works at all.
