At long last, I’ll now be able to use all of my large-format lenses on both my Toyo 45AII field camera and my Horseman L45 monorail, without swapping lensboards. I bought this Horseman when film cameras were at rock-bottom value; I think I paid $200 for it.

The lensboard adapter mods are done, at least for now; at some point I’ll pick up some Testors model paint and blacken the filed areas.

I considered sending the adapter back, of course, but decided on this course of action instead. It’ll work perfectly well, at a much lower cost than the alternatives. Plus, as they say: a bird in the hand, yada yada yada.

I’m in the workshop, taking a bastard file to a beautifully machined Toyo Field-to-Horseman lensboard adapter. Unfortunately, the radius used for the adapter’s opening was too large to accommodate the raised light trap cast into the back of the Toyo lensboards.

I was able to bring my LF camera up onto the Wapta Icefield and Bow Glacier for my recent fieldwork. It's been nearly 20 years since I've exposed any 4x5" sheets of film - far too long! I can't wait to develop and print the small number of images I was able to capture. (Add'l info in alt text.)

Here I'm checking the composition one last time on the ground glass of my Toyo 45AII field camera in preparation for taking an image. Before inserting the film holder (seen here in my left hand), I'll check and re-check that all of the various knobs on the camera and tripod's ballhead tight. Failing to do so means that the camera will invariably shift as the film holder is squeezed into place, wrecking the careful composition. This shot, taken from the north margin of Bow Glacier, included some of the Bow Glacier ice, The Onion (out of frame to the left; its low, broad peak is popular with day-hikers and non-technical hut-stayers), St. Nicholas Peak (visible here in the distance), and - of course - the dramatic clouds. During this trip, I shot on Ilford's FP4+ (ISO 125) and HP5+ (ISO 400) panchromatic black-and-white sheet films, depending on lighting, wind conditions, and overall scene contrast. For most of the images, I shot through a Hoya Orange (G) filter to increase contrast in the clouds and ice (though at a penalty of 1-2/3 stops of light). I used f-stops ranging between f/22 and f/45, generally with shutter speeds of 1/60 to 1/15 s. I brought two Rodenstock lenses on the trip, a 90mm f/6.8 Grandagon-N and a 210mm f/5.6 Grandagon-N; these are roughly equivalent to 30mm and 70 mm lenses for 35mm (or digital full-frame) cameras. Here I'm using the 210mm lens. For this particular scene, it would've been nice to also have my 150 mm f/5.6 Nikkor-W for an alternative composition, but I'd made a last minute-decision to leave it behind to reduce total weight and bulk.

Nah; it’s a great part of The City, and great even for short breaks from talks. A couple of decades ago, a nearby building (at corner of 3rd and Mission) had these murals painted on them; now the faces on which they were painted butt up against buildings (The Regis on one side, MOAD on the other).

A classic San Francisco building with a mural painted on one side. The mural is stylized as a one-way traffic sign, pointed vertically upward with the word “SKY”.

That sounds about right. I’m well aware of what I’m setting myself up for - the hike to our field site (which I’ve hiked about a dozen times over the past ~8 years) is approximately 10 km (6 mi) with a 750 m (2500’) elevation gain. So it’s not negligible.

Some quick scans (using a Nikon Coolscan 5000ED) of the test roll of Ilford XP2 Super I ran through the 1956 Leica iiif w/Elmar 5cm f/2.8 lens I recently picked up. It did not disappoint! This is not (and won’t be) a film I shoot regularly, but it’s pretty great. Two Bridges.

View through the iron girders of the High Level Bridge, looking east towards the Walterdale Bridge.

At 4000 dpi (e.g. via drum scan), that would be roughly equivalent to 89 megapixels - with each pixel containing full RGB information.

Years later, I’d frequently see one parked near the UC Berkeley campus. It wore a “Ralph Nader for President” bumper sticker. I always wanted to ask its owner whether (s)he was being serious or ironic.

A friend of mine in high school had one, and other members of her family owned several more. I have very fond memories of riding around in that car - whether or not it was “unsafe at any speed.”

I get it; for what it’s worth, I’ve never taken any safety precautions for any other earthquake, before or since (though they’re not much of a concern in central Alberta).

It was after getting to the doorway that I watched the building sway and road surface 'wave'...

I'm the sort of weirdo who loves that sort of thing (plus being on the ocean in big sea states, tentbound in Antarctic blizzards, etc.). It lasted long enough for me to think to myself, "ya know, perhaps you should get to a doorway for this one."

I still vividly remember the Oct. 17, 1989 Loma Prieta ("Bay Bridge Series") earthquake. I was just ~17 miles from the epicenter in downtown San Jose, CA. Watching the apartment building across the street sway as the Rayleigh waves rolled visibly by - well, that was a trip.

Now I regret disassembling the seismometer I'd been testing in my garage.

…but we’ll be staying in the ACC’s Bow Hut - so I won’t need to carry a tent or stove. At this point, I honestly don’t know whether I’ll carry it or have it flown up. Overall, I’d prefer to carry it - but we’ll see once everything is together in a pile.

Whatever AA said instead of “don’t scrimp…” was probably less useful advice (provided one wanted to shoot an 8x10 in the High Sierras). I’ll have to figure out the weight and volume of the rest of my gear before deciding. I’ll be carrying tools, a radio, and food for a week-plus…

There’s a chance I’ll carry the camera gear up with me - I’ll be hiking both in and out; the helo is for moving equipment - but there’s an admittedly greater chance that I’ll have the 407 carry it up to our field site. Either way, I’ll be the donkey carrying it back down.

The donkey:

A Bell 407 helicopter, potentially the very one that will support our fieldwork, operated by Alpine Helicopters.

Let’s unpack this, shall we? Trump is apparently claiming that: (1) the Epstein files were made up by Comey, Obama, and Biden to make him look bad; and yet (2) Trump’s name doesn’t explicitly appear in the files.
