A photo of President Lincoln I found. Converted from parallel view.
Recently discovered the Boston Public Library’s online stereo card collection. There are almost 2,500 cards in the collection. Linked above is my favorite s far.
They’re all parallel view, fyi.
Work work work
I haven’t had a chance to shoot any new work since Mexico City because I’m currently working full time on a book project (a sequel to “The Elements”). When it’s done in a month or two I’ll hopefully be shooting (and therefore posting) more.
Got a Burning Man ticket yesterday. Looking forward to shooting 3D stuff there.

Gallery from the largest Cathedral in the Americas. From Wikipedia:
The Metropolitan Cathedral of the Assumption of Mary of Mexico City (Spanish: Catedral Metropolitana de la Asunción de María) is one of the oldest and largest Roman Catholic cathedral in the Americas and seat of the Roman Catholic Archdiocese of Mexico. It is situated atop the former Aztec sacred precinct near the Templo Mayor on the northern side of the Plaza de la Constitución in downtown Mexico City. The cathedral was built in sections from 1573 to 1813 around the original church that was constructed soon after the Spanish conquest of Tenochtitlán, eventually replacing it entirely. Spanish architect Claudio de Arciniegaplanned the construction, drawing inspiration from Gothic cathedrals in Spain.

I’ve been busy with a work project, other personal projects, and procrastinating. This blog will become more active in the future. You could consider this a dormant(ish) period.
If you like maps, you many like this recent creation of mine (higher res recommended):
Review of the Panasonic GX7 on a Stereoscopic Rig
This is a review of a pair of Panasonic GX7 cameras on a stereoscopic 3D rig. It follows about two months of use, and ignore aspects irrelevant to normal shooting (such as the feel in your hand or the electronic viewfinder).
External Camera Design:
Size wise, these are good cameras. There’s nothing at the top that prevents the cameras the from getting right up close to each other.
The tripod port is in line with the center of the sensor (unlike the cameras in my previous rig, the Olympus E-P3).
Happily, the external trigger port is on the side opposite the grip, meaning that when the cameras are placed on the rig the trigger cable is more-or-less protected at the top and doesn’t get in the way at the bottom (again, unlike my previous rig).
Annoyingly, a standard 3-pin 3/32nd audio plug won’t trigger the cameras. You need this cable and a male to male adapter to trigger it. (Panasonic also sells it’s own more expensive cable, I believe.)
The cameras can show both the level and a grid at the same time while shooting. This is good. Other than that there isn’t much to say about it.
There are basically three ways to focus: Auto, Manual w/ Focus Peaking, and Manual without peaking. Sadly none of these work very well, the latter being the least bad.
The autofocus on this camera doesn’t work well, especially not with the Olympus 12mm F/2. I spent several days shooting photos of trees with the rig on autofocus and in an unacceptable percentage (perhaps around 25) at least one of the cameras focused past infinity instead of on the tree, resulting in an unacceptably soft photo.
When shooting with other lenses and closer subjects the cameras preformed a little bit better, but many photos were still unacceptably soft. Auto is only worth the risk when the subject is moving too quickly for manual (such as animals).
For manual focus, the peaking feature is not precise enough for anything close to wide apertures. It is only useful at small enough apertures to see if broad areas are in focus.
That leaves only manual focus without peaking, which I now use as my default. It’s fine as long as extreme care is taken. It’s easy to glance at the screen and think the focus is where you want it, only to later discover it was slightly off.
The focus problem is made worse by low quality image playback (at least in RAW). The camera plays back very low quality photos, making it basically impossible to see if the focus is accurate.
The Electronic Shutter, Stabilizer:
You can’t use either the electronic shutter or the stabilizer for moving subjects. For the electronic shutter, the camera pulls the data off the sensor continuously, rather than all at once, causing problems (crossview sample here). For the stabilizer, it causes the cameras to fire much less simultaneously.
Other Shooting Notes:
The cameras don’t always fire completely simultaneously. Sometimes they do, but they don’t always. I understand this is an issue with basically all camera rigs.
The cameras produce images close enough to the same color (which is to say, very close) when set on the same white balance. HOWEVER, very annoyingly, Adobe Camera RAW thinks they have different white balances. Therefore, when adjusting the WB in post I can’t just set the cameras to the same number, but have to offset them just enough from each other (it’s not always the same degree). It’s a really big pain in the ass.
Screenshots from ACR showing “As Shot” WB but different numbers:
On a whole they’re good cameras as long as great care is taken when focusing them. The only real problems are misfocusing on auto, low quality image playback when shooting in RAW, and inconsistent white balance numbers in post (although that’s really more of just an annoyance).
For samples, please see basically all of my posts since mid October.
