K20D with the SMC Pentax-DA10-17 fisheye, stitched with PTGui from 7 originals.
This is Stockholm (capital of Sweden) shot from ~115m above sea level (you can hint the baltic sea in the inner archipelageo on the upper right, north-east). I'm standing on a ~12m metal frame tower on top of the elevator machine room (dark grey square) on top of the concrete tower. The elevator goes to the 20th floor, after which we have to climb three steep stairs indoor, a fourth outdoor up in the machine room roof, and then 12 m vertical ladder to reach the platform. The tower is used for radio communication and mobile phone networking.
From the platform my research group at Stockholm University samples the concentration of carbondioxide and aerosol particles and turbulent motions which enables us to derive the emissions of both carbondioxide and aerosol particles from traffic combustion to the north and west of the tower. In the south to south-east we instead see how the forest area takes up carbondioxide through the photosynthesis of the plants and how particles are deposited.
The purpose of this photo is to show the surroundings and the different source or sink regions for carbondioxide and particles around the measurement site. It will probaby be included in some posters on scientific conferences and some publication in scientific journals together with measured data.
I'm not completely happy with the result because after having taken some shot inside the machine room where we have our computer and data logging I forgot to decrease the ISO when I got up onto the platform, so I need to go there again with the camera. Then I will probably also try to use the SMC Pentax-DA15mm ltd. After this shot I changed the settings on my K20D so that the top display show the ISO instead of remaining pictures on the memory card. Hopefully it will help avoiding such misstakes even when I'm in a cold and windy place like this.
Some land marks: to the north to north-west are the central Stockholm including Södermalm and the old town. If you zoom in there are many familiar land marks for those who are familiar with Stockholm. Just north of the tower is what used to be a worn down harbour area, Hammarby-hamn, but is since a few years a fancy living, office and shopping area (large emissions from cars here). Just north-east of the tower surfaces one of the exits from the long traffic tunnel that goes south of Stockholm. The green area to the east and south-east are the northern end of the Tyresö park, a large protected green area, but as you can see, the living areas just south of the tower are also rather green with low emissions. To the south-west you can see the indoor arena "Globen" (the white globe), a well known land mark of modern Stockholm (no it was not where Hamlet put up his original plays).
I must say that I'm really impressed by the PTGui software. Powerfull, easy to learn, inexpensive. The demo version let you try most functions.
Middle age male, father of two daughters. Makes a living as a research scientist, working at Stockholm University. I like to consider myself an open minded, fair and creative person. Like all kids I had some dream occupations. One was to be a photographer. Another, the most persistent, was to become a scientist, which I did, quite successfully. But somewhere below the surface is still that kid who wanted to travel the globe with a camera (or several and many expensive lenses). Here I will live out that part of myself.
