In about 2005 on f295, Earl Johnson organized a group buy of Gilder Electron Microscope Apertures. I once produced a slide/tape tutorial on how to insert them into the microscope. (Open the vacuum valve first!) They only come in tubes of 100. Earl got one tube of each size and distributed 10 of each to everyone who participated. One of the .15mm is on The Populist. I've used all the smaller ones since but I still had the bag of .4mm. I just gave a talk with a microphotograph of one of them along side my hand-drilled pinhole and was impressed by how perfectly round they are with a smooth thin edge. Despite my philosophical reservations and to get out of drilling them myself, I installed two on Long John Pinhole. Still not quite optimal, but a lot closer than the .33mm pair.
This is an excellent example of the utility of the 200mm camera. I've stopped and unloaded the tripod several times in the past for these white cubes atop the rough bricks. When approaching close enough to frame the scene, the point of view becomes significantly up and the wall hides the cubes. You could get something like this view with a wide-angle camera but you'd have to be 25 feet tall, and then the relationships would be different. With the 200mm, the composition as originally seen when riding by it was preserved. I nailed the pointing on this one by the way.
Down the street at another corner of the Water Treatment Plant, this trick with the 200mm wouldn't work because there was a tree in the way, and it's quite a downslope to the street so the viewpoint wouldn't change at all. I could get what I wanted in the frame with Long John and also had the rising pinhole to keep the verticals parallel.
When out with the 200mm in the past, I stopped and began to frame up this unusual apartment building, but didn't take the photograph because the lighting was exactly like this—a sunny day with the sun directly behind it. I always said I'll have to come back on a cloudy day but I never did. They're in the process of tearing it down, so I'd better take the opportunity. It's always been covered by this odd yellow stucco and in my selfish photographer's heart, I think it makes a better photograph with the dark lumber exposed. I was surprised by how far back I had to go into the park across the street to get the framing I wanted, which again turned out pretty accurate.
I couldn't get that far away from this old smokestack and vine covered walls, so Long John was the only choice, and to avoid tilting up, used the rising pinhole. This is one that might have been better to wait for a cloudy day, not because of anything to do with pinhole, but because it would have featured the vegetation better.
Tight cropping is the essence of a narrow angle camera. I was again surprised how far away I had to get for the whole side of the bank to be in the picture. Despite being only eight stories high, this gives me the impression of my memory of the giant wall of buildings across the Chicago River from Wacker Drive in the Chicago Loop.
A few yards to the left of where the camera was for the bank picture, the sun defines the planes of the back of the Exclusive Company, with Long John's rising pinhole.
Oshkosh is pinholier than I thought because there's this giant advertisement for the most traditional pinhole camera ever—the famous Quaker oatmeal box. A double cylinder with the the lid removed by a string dividing the outside near the top to make the easiest camera to light-proof. No problem getting far from the wall in the parking lot and used the 200mm. I had to tilt up a bit but with this narrow view, it's hardly noticable the verticals aren't parallel and more to the point, doesn't look like the building is falling over backward.
Staying with the 200mm for this arrangment on the back of The Grand Opera House across the alley. I was backed right up against the rear exit of a photographer's studio.
This balcony sticking out from the City Center Mall used to be an exit from the parking ramp. A few weeks ago I considered this picture when out with the 45 and 30mm cameras. Nearer to it, looking up, it didn't look anything like this arrangement. I could get well away from it to use the 200mm.
