Socialstyrelsen och folkhemsfascismens diskreta charm

Jag har alltid betraktat Socialstyrelsens lilla kontorskomplex i Marieberg som ett ganska oansenligt men faktiskt trevligt stycke arkitektur som på sitt vis passar mellan SvDs gamla skrapa och Riksarkivets bunker -- flera generationer tegelarkitektur som trivs tillsammans. Det jag främst uppskattat är dock det rum på gården som lite vilset står på styltor mellan tegelfasaderna och inte riktigt vet om det ska gå till vänster eller höger.


Jag blev lite förvånad när jag i Guide till Stockholms arkitektur läste att när det begav sig i början av 50-talet associerades byggnadens "nyrealistiska" estetik med Nazi-Tyskland. Tydligen var det portomfattningarna som framförallt stack i ögonen, men även den stiliserade takfoten i sten ovan provocerade.


Själv har jag inte ens sett att den fanns där. Den saknar såvitt jag kan se funktion men sticker i övrigt ut så lite som möjligt. Jag har faktiskt lite svårt att klumpa ihop tegelkomplexet i Marieberg med Albert Speer.

Essingeleden piggar upp


Tog en promenad idag -- lite gråmulen novembermånad piggar alltid upp.

De senaste veckorna har jag nu-å-då kollat in Essingeleden och dess broar och viadukter. Idén var från början att använda denna grå och mörka årstid till att fotodokumentera något som är grått och trist. Det finns dock många fina rum som gömmer sig under denna megastruktur -- som ovan i Gröndal t.ex.

Broken Column


I finally opened Blender again -- hardly had the time since this spring. I spent most of today modelling a column. I'm not entirely sure if I got proportions right, but I was happy modelling again. I could probably have achieved something similar using far less vertices.


Anyway, I then created a vertex group for the top of the column and added two displace modifiers using the clouds and stucci textures and two empties for coordinates.


Simple effect. Fun modelling. I wish I'd ever get started with materials though.

Architectural sections with Blender


I just created a tutorial on how to create an architectural section in Blender using material nodes. Check it out: Sectioning a mesh with nodes

Funny failure

I'm trying to teach myself rigging basics. I forgot to parent the armature to the mesh and rotating the latter was probably the coolest thing I achieved today. *Sigh*

Last ice HDRed

Looks like spring finally won the battle. While the snow is gone and ice is on the retreat, the latter is still covering the canal outside my window. The poor mallards and coots look funny when they try to walk on the remaining slippery ice.

I spent more than two hours today trying to pin-down the Durand algorithm in Qtpfsgui with no obvious success. Apparently it was updated rather recently and I can't find any documentation whatsoever anywhere. Increasing the "Spatial Kernel Sigma" value seem to make the brightest areas shine through. "Range Kernel Sigma" seem to increase contrast and enhance detail at the cost of haloes in high-contrast areas.

Another hour in the GIMP resulted in an acceptable image.

Bellmansgatan HDRed

I spent a moment today experimenting with HDR and made some new discoveries.

With my camera, (Olympus Camedia C-765) I'm only able to use bracketed images in JPEG format. Until today I've done all the HDR work manually in order to get TIFF images, but today I discovered how to tweak the tonemap settings in Qtpfsgui to eliminate the artefacts I thought were produced by the JPEG compression in my previous photos.

So I took a series of five photos at the Bellmansgatan street, imported them into Qtpfsgui, and tonemapped them using the Mantuik and Fattal algorithms. I then used various layer modes and filters in the GIMP to combine the tonemaps.


I'm still far from achieving a natural colour scale using HDR, but by using some of and part of the original photos ontop of the tomemaps I got a lot closer.
