Hey, look! A picture of the full moon!
What’s special about this? Well, *I* took it, so there’s that. But I also took it with an iPhone.
So those of you who have tried taking a picture of a bright moon know that you usually get a giant blob like this.
The iPhone can actually adjust the exposure quite well, but for some reason it can never lock onto the moon.
So here’s the trick: point at a lightbulb and tap/hold to lock the exposure.
Then go point at the moon:
Zooming in, you’ll get a crisp but smudgy picture.
Reminiscent of Percival Lowell, though no canals:
To make it more crispy, I applied the witchcraft of the Photojojo telephoto lens, et voila:
Some sources say Daguerre himself made an image in 1839, but it was destroyed in a fire than consumed his lab that same year. John W. Draper made this daguerrotype in 1840 from NYC.
The marvellous David Rumsey has attacked yet another set of maps for our historical education.
Eleven California Freeway and Expressway Maps, 1962 – 1975
California Department of Transportation, Division of Highways, Sacramento.
These maps show the development of the freeway and interstate highways in California over a period of 13 years, from 1962 to 1975 when the system grew exponentially. The maps include regional enlargements of San Francisco Bay Area, Sacramento, San Diego, and Los Angeles. Maps obtained from the Institute of Transportation Studies Library (Harmer E. Davis Transportation Library) at the University of California, Berkeley.
These maps show in remarkable detail the growth of highways and interstates we know and love like 280, as well as “ghost” highways that were planned but didn’t make it. They are absolutely enormous — here’s the full 1962 map on davidrumsey.com with pan and zoom controls.
As not to bury the lede, using the power of BurritoVision, I made a GIF showing highway construction (and plan evaporation) in and around San Francisco from 1962 to 1974.
Here’s the key:
- Red: finished
- Green: under construction
- Yellow: route accepted
- Blue: planned, not yet adopted
Here’s the inset map for San Francisco and the Peninsula in 1962.
There is all sorts of fascinating on this map. In addition to the highways that were to cut through San Francisco, perhaps the most flabbergasting is “Highway 289″ (aka Highway 87) which was to run on/along/in the western coast of the Bay. (A small nub of 87 was built down in San Jose, but stopped at 237).
We saw this particularly destructive piece of Bay-eating engineering a few years back when we discussed it in the 1960 San Mateo County Master Plan.
And yes, that is a dam along the Dumbarton Bridge. Newer readers may want to review the various proposal to dam the Bay over the years.
Anyway, back to these new maps.
The intra-SF highways disappear after 1965 when the Great Highway Revolt finally shot them down…
And 1969 is the last year that Highway 87 shows up.
380 was originally supposed to stretch from 87 (just north of SFO) all the way to Pacifica — so you’re not imagining things when you drive westbound on 380 towards 280 and it looks like they forgot to finish it.
It should come as no surprise that Eric Fischer recently dug up the proposals for the path 380 might have taken to the Pacific:
This and many other 380 maps over on Eric’s always educational highway and bridge plan Flickr set.
The 1971 map looks more familiar in terms of highways, and BART shows up as well. One notable exception is a Southern Crossing bridge from Hunters Point, with a split to both Alameda as well as to the Oakland Airport.
(I think this path would make a fine extension to BART, anchored by a 30th St La Lengua station, naturally.)
Most Interstate construction as we know it today is complete by 1974-1975. So you can see the progress, I jammed the Bay Area insets from all 11 maps in a gianormous 53 MB GIF — each frame is 1800×2400 frames, so once it downloads you can zoom in to your area of interest. (Someone feel free to do the same for Los Angeles. Or better yet, vectorize the entire state with an HTML5 playback mechanism…)
Let us all bow our heads and remember the 300,000 IPAs that were lost when the Edwin Fox ran aground off Chennai in 1869.
May god have mercy on their hops.
Views of San Francisco from the International Space Station are a primary mandate of this blog. Pictures of Sutro from space, even more so! Hey Sutro!
Here’s the full shot from which I pulled the Sutro crop:
It includes a nice angle on our bridges:
In addition to those showing up on Twitter, all the photos taken by astronauts on the ISS are archived by NASA at The Gateway to Astronaut Photography of Earth. While it takes a while for them to be catalogued and geotagged, you can search through the raw feed and find sequences of pictures as the ISS travels at Mach 25 over SF.
I’ve been experimenting with creating stereograms out of closely timed photo sequences, with varying levels of success. If you can do the cross-eyed thing, here’s a Sutro stereogram made from this and this shot.
(Note also Dolores Park and Bernal.)
And the Golden Gate Bridge:
Not quite as much relief visible as I’d hoped. Given the altitude, I think stereograms would work best with oblique shots of mountainous terrain, taken tangentially (sideways) to the direction of travel of the ISS. (Then again, I am neither an astronaut nor a photographer.)
And mainly because they are awesome, a quick review of previous shots of the neighborhood from the ISS:

ISS from my yard:
p.s. You can’t save search results on the The Gateway to Astronaut Photography of Earth site, so to save you some time, here are the most recent SF sets:
The views from Bayview Hill (420′) are amazing — a clear view from Sutro to the Bay Bridge.
There’s a nice trail that takes you all the way up to the top, and the plants are pretty distinct (PDF).
Cool WPA-era stairs (that are apparently covered with poison oak, so watch out).
Here’s what the very top of Bayview Hill looks like.
You can also see the Burrito Railgun in its native habitat:
And Sutro, naturally.
Behold Bernal and the tip of the GGB:
