Upgrading with a new processor and hard drive
When I started with photography the dark room was the second-best place to spend time. At least for me those dark room days are long time gone and today I do almost all work with a computer. I even have my camera and my microscope controlled by computer. So, a malfunctioning computer can have the […]

Even if photogrammetry can be very useful it has a lot of drawbacks. In this series […]
A visit to Wira bruk in Upland
On my way back from Häverö prästäng a nature reserve in Northern Upland I decided to make a short stop at Wira bruk. Today this is a beautiful and peaceful little village, perfect for a half an hour walk. The forge started 1635 and produced swords. In more peaceful times they made scythes and axes. […]
