Michele + Jet in Philly (Zagar A208)

Sometime around 2017 we visited Philadelphia to take in a concert by Raffi, whose music Jet just loved to pieces. It was the furthest South that Raffi had ever travelled in his very long career of live performance for young audiences (Raffi is Canadian). Raffi is getting pretty old these days, so we jumped at the chance to go see him. Of course, a stereoscopic angle had to be included, so I undertook to find some of Isaiah Zagar’s thousands of murals. He has practically covered Philadephia with these distinctive works, which have a lot of stereoscopic interest, on account of the liberal use of bits of mirror. Learn more about Zagar’s opus here: https://www.phillymagicgardens.org/about-philadelphias-magic-gardens/about-isaiah-zagar/
Photography was done with a Sputnik shooting Velvia 50. But the weather was not as bright as I had hoped for. On the ground you can see my test exposure rig, a twin rig Sigma DP1 Merrill.

Scrutinizing Sharpness (Ian Andvaag A33)

For this loop, I wanted to get some feedback on sharpness. I’ve been working through some of Mike Davis’ spreadsheets and trying to determine if I’m leaving a meaningful amount of sharpness on the table by using a TL-120 or Sputnik. As I understand it, Mike’s contention is that it is not possible to get critically sharp slides with appreciable depth using standard 60-65 mm stereo base and normal FL lenses. I’m rather surprised by this contention after having seen many fantastic slides taken with TL-120s and Sputniks, but I know it’s easy for one’s eyes to be fooled, and I would guess that 95% sharpness looks close to 100% sharpness. I will say that I was particularly struck by David Lee’s Yosemite Fall slide that was included by John Thurston this loop, which seems impossibly sharp, and was not taken with a standard stereo base. I believe the proper way to investigate sharpness would be to shoot some scenes with resolution test charts at various distances and then to side by side A/B comparisons with the resulting slides in a viewer. I wish I could ask Don for advice, I know he occasionally did tests like this 🙁

 

With all this in mind, I picked out several slides which I personally believe to be quite sharp, and I would appreciate any feedback from others about any perceived lack of sharpness. Cloud Inversion should probably be considered as the “base case”. I believe the nears were around 50′ and I focused around that point, shooting at f/16 I believe. I believe this should secure more sharpness than the eye is capable of detecting in a standard viewer. I don’t really know anything about a cloud inversion, maybe this should better be called thick fog that settled into the valley.  Anyway, it was rather unexpected and interesting to see when I woke up to photograph at sunrise. There is a bit of retinal rivalry in the clouds and shadows as this is a chacha with a tripod and it takes some time to set up the tripod and adjust the framing. Apparently quite a few dinosaur fossils have been found in these badlands.

Cloud Inversion

 

I perceive Gem Lake Reflection to have a high degree of sharpness, however I don’t think it is objectively sharper than any of my other standard TL-120 slides. I believe the perceived sharpness is largely due to the adjacency effects caused by the high acutance first developer, along with the fairly visible grain.

Gem Lake Reflection

 

Bryce Hoodoo, yes this is a Sputnik shot, and there probably is some falloff in sharpness towards the corners, but I’m not sure I can detect it! Maybe the pine needles at the far right are a bit soft. This is a pretty “easy” shot to secure sharpness as the deviation is quite low, (the nears are rather far away) but I would be surprised if I changed the aperture off the default f/22 hyperfocal setting. I do think the rock and ground appear sharper than the objects in the far distance, but I’m suspecting that this is more due to the haze and lack of high spatial frequency information in the distance rather than the Sputnik having overly relaxed hyperfocal markings, although it could be both!

Camping Breakfast was shot at f/22 using the standard hyperfocal markings on the TL-120 and I used the entire range (the near distance was 3 meters). I might be able to detect the smallest lack of sharpness in the specular highlight on the blue water bottle, but I’m not sure. I think the exposure was 1/8 of a second, so the people are probably not perfectly sharp. Yes it was posed!

Camping Breakfast

 

In my opinion, Cloud Inversion does seem ever so slightly sharper than the others, but I’m not entirely convinced it is because of the more conservative DOF tolerance, but rather that the size of the plants at this distance provides a fairly high frequency subject and the low angle of the sun provides fairly high contrast, while non-hyper shots typically have inherently less high frequency detail.

 

So what do you think? Do you use the standard hyperfocal settings on your lenses? Or do you stop down one extra stop? Or some other technique? Ok, enough nerd talk. Sorry to ruin a perfectly good post with all this talk of sharpness! I certainly don’t think it’s the most important aspect of a successful MF3D shot, but it is fun to discuss.

Last year was our 25th wedding anniversary. Those of you who were in the original MF3D Folio II might remember my honeymoon stereos from Ireland. For this trip we went to Trenton, NJ, where my brother-in-law (who married us) is currently a Bishop of the Episcopal church, so Liz could play the pipe organ there. And then it was on to Philadelphia.

This Roman Catholic cathedral was opposite our hotel in Philadelphia. We hadn’t really thought to try and get in see the organ here. We did see the Wanamaker Organ, but I didn’t think I could get a good exposure without a tripod.

My slides in this loop show a walk on a nice day in Philadelphia to City Hall.

This is Swann Memorial Fountain in Philadelphia. Several of Philadelphia’s museums are located around this square.

This scan shows the least intrusive vignetting I had from my lens shades on this trip. Luckily the 6×4.5 mounts allow me to crop it out in this case.

This is Love Park in Philadelphila. The statue in the foreground is very similar to ones I’m more familiar with seeing back home in New York. The traditional Philadelphia Love statue can just barely be seen on the other side of the fountain. It faces the wrong direction to get City Hall in the background.

Temple Mount, Jerusalem, Israel 2018

Temple Mount is a very important site for Muslims, Jews, and Christians. It is a beautiful courtyard in East Jerusalem and is defined to be one of the holiest sites in the world. The al-Asqa Mosque is a sight to see, and since it was a beautiful day when I was there, I went nuts trying to capture it’s beauty shooting from all angles. This shot was one of my favorites of what I captured. The walled arch in the picture is called the scales of judgement, believed to be the place where people would be judged before entering the gates of heaven. Note the sundial on the arch.  Israel is filled with religious history and a must see for anyone interested in the subject. Shot with my Sputnik, on Fuji Provia 100f. 

Cormorant Fisherman, Guilin, Guangxi Province, China 2018

In a gorgeous area of China, on the Li River in Guilin, there is an old form of river fishing. The fishermen use cormorant birds to catch fish. The way it works, is that the fishermen would raise the birds from chicks and the birds would then trust the fishermen. Once old enough, the birds would start fishing by instinct by diving to get the river fish. The birds would dive into the river, and come up with the fish in their mouth, which would be snatched from them by the fishermen. The birds would eventually be rewarded, albeit with smaller fish. This practice of fishing is actually not really used much anymore, and has become more of a novelty for tourists, like myself. I wanted to get an iconic image of the fisherman while I was there, but unfortunately the opportunity did not present itself. However, an easy going fisherman let me do a snapshot of him while we were walking down the riverbank. Shot on my Sputnik, with Fuji Provia 100f.

Kathmandu Durbar Square, Kathmandu, Nepal 2016

Kathmandu Durbar Square is an incredible area of Kathmandu, filled with old temples originally built and rebuilt from around the third century. We arrived one year after a major earthquake damaged many buildings in this square. It still held up it’s integrity and prestige even after most of the damage. Sadly some of the temples were reduced to rubble and were only recognizable by placards set up by the tourist government. Due to the damage to Nepal and to it’s infrastructure, there seemed to be less tourists than we had anticipated while we were there, and allowed us to explore most areas in less crowded situations. This shot was taken in the early morning, while locals were out feeding the pigeons. Shot on my Sputnik, on Provia 100f film.

Cusco Cathedral, Cusco, Peru 2017

Cusco is a fascinating town in Peru located near Machu Picchu, and is often where travelers acclimate to the high altitudes before heading off to the famous ruins. There are many old buildings built by the conquistadors, often using stones originally cut out by the Incan, scattered throughout the town. One of the more ornate and beautiful buildings is the Cathedral Basilica of the Assumption of the Virgin, or Cusco Cathedral for short. While we were out walking one evening, I wanted to stop and get an interesting shot of the church lit up. While walking up the steps to the church, I noticed that there were two Quechuan women sitting on the steps. This was taken on my Sputnik, when it was still working properly, on Fuji Provia 100f.

The Built Environment – Architecture and Machines

Ages ago, I shot this view of the (then) new UVA Hospital with a Hasselblad, maybe two of them on a bar – in any case this is a cha-cha to obtain the necessary stereobase, which was probably around a foot, judging from the parallax in the image. I imagine the exposure was around 30 seconds. Extra credit for the astronomers in the group that can identify the stars in the sky:

UVA Hospital, Charlottesville, VA

My “day job” is technical illustration. My clients are engineers at the University of Virginia, mostly. One day I went to visit a lab, and discovered this gigantic machine. Impossibly complex in its construction, for all I knew it could have been a time machine. So I started calling it the “time machine,” whenever I mentioned to my engineer client, and that I’d like to come in some day to photograph it. The title of the image that I finally made says about the same thing. For real, this is a Directed Vapor Deposition machine. A big electron gun hits one material, vaporizes it, and the vapors are deposited onto another material. Believe it or not, it is not a custom made machine. You buy these things retail. Cost? about $1M:

Temporal Continuum Distortion Analyzer (Posterior Aspect)

In or around 2012, I had the opportunity to photograph inside a retired coal-fired power plant not far from where I live. This plant, in Bremo Bluff, VA, was the first “automatic” coal fired power plant built in USA. “Automatic” meant in those days that most of the valves, flaps, conveyor belts, and other machinery was centrally controlled. Which means, there was a central control room, where through the use of electrical switches, one could remotely actuate any of the hundreds of valves in the plant – as these were electrically actuated. I’m sure there was a measure of fear or distrust in the system early on, as plant operators were instead used to shouting control commands at a team of plant workers, on whom one could surely better rely to get the job done than the new-fangled electric motors.

I worked on three separate days in the plant to make photographs, using with great pleasure John Thurston’s custom TL-120-55 for the wide angle views. I am forever indebted to John for his generous loan of the camera to me that year. In this view we have my old friend Chuck Holzner up there on another level (see the white hard-hat?) taking some of his own pictures. Along the left side of the view, rising up through the various levels, is one of the four burners in the plant. These are 100 foot tall furnaces (not counting the smokestack outside the building!), that included Ash removal apparatus at the very bottom, a furnace chamber 1/3 of the way up including hundreds of pipes for heat exchange (i.e. for boiling water, making steam), and at the top a variety of filters to capture particulates in the exhaust. I’ll guess this was a three seconds exposure:

Bremo B 418 Main Room

Elsewhere in the plant, I captured this view of just a tiny fraction of the pipes and plumbing that, along with grated floors and vast spaces, characterized the place. Probably a thirty seconds exposure in this dark spot:

Bremo C 515 “Pipefitter’s Nightmare”

I’ll close with an image obtained in or around 2014 at the United States Botanical Garden in Washington, DC, where I fell in love with the “Jungle” greenhouse that is central to the place. In this three-stories tall greenhouse, one can commune with a variety of lush tropical plants, even in the deep of winter, and witness the slow motion battle between the built environment and the imprisoned flora. This picture was taken with a Sputnik, a good bit after sunset – I like the interplay of just a little natural light in the background, with artificial lights in the foreground. I imagine about a ten or twenty second exposure.

Beetle at the Night Market, Oaxaca, Mexico

This was another part of Oaxaca that I wanted to shoot at night. The market was very nearby, and the nightlife carried out into the streets. I really wanted to capture a Beetle while I was there as well, since they are such a part of Mexican culture and are common throughout. Needless to say, I was happy to see one pull up and park near where I standing while taking a different photo down the street. So happy that my ‘other’ Sputnik has sharp matching lenses, it really helps to get the shot right! Shot on Fuji Provia 100f film.

Nighttime Zocalo, Oaxaca, Mexico

I wanted to get a shot of the zocalo (or center of town) at night. There was a lot of activity in Oaxaca at nighttime, and it is such a large part of the overall culture of Mexico. It felt very safe to walk around with a tripod and camera. Not many people paid any attention to me, which was exactly what I wanted. The wind was doing me a favor in making this image a bit more interesting. Shot on my Sputnik, with Fuji Provia 100f film.

‘Chillin’ in the shade’ – Monte Alban, Mexico

Just outside of Oaxaca is Monte Alban. They are Aztec ruins, said to be over 2,000 years old. Very neat place to go and very easy to visit while in Oaxaca. I came across this gentleman hanging out under the shade of one of the few trees within the grounds. Thought that it captured the overall sense of the heat that day. Hit at least into the 90’s, but coming from cloudy Seattle, it was a welcoming sun exposure for me. Shot on my Sputnik, Provia 100f film.
