My first photo of a wild pheasant

Texel nature

Here are some photos from my stay at Texel. We had fog one of the days, obviously the day I went down to the sea.

Software Architecture Workshop 2014 – Texel, Netherlands

About 10 years ago a man called Jimmy Nilsson invited a group of people to an Open Spaces workshop in Malmö called Software Architecture Workshop. This workshop has been an annual event since and this years event took place on an island called Texel located in the Netherlands. This was the second time I participated, and I loved it this time around too. The participants were a bunch of enthusiastic, skilled and very friendly technically minded people. The discussions ran freely both during the evening and during the day, so I think most of us were totally worn out after the three days. If you do not know the format – Open Spaces is a very free kind of workshop. We put up an agenda divided into rooms, and people suggests topics. Usually something we struggle with, or something we want to discuss a bit. Hopefully some other people have done this or are interested enough in joining to participate. You are free to change from one discussion to another any time you want.

Here was our final agenda:

Another Candle-Wick

These two photos is taken are both taken with my Canon MP-E65 lens, and shows the difference between 1x magnification and 5x magnification.

Notice the drops of wax on the wick in the topmost photo. They are glittering like water droplets.

A new lens

Canon has maybe the ultimate macro lens you can buy. It is called Canon MP-E65. It is a somewhat peculiar lens, but if you want magnification and don’t want to build it yourself, this is a lens to consider.  I recently managed to get hold of one and have played around with it for almost a week now. It is winter in Norway and the kind of images I want to test out is really not possible at the time. So instead of showing you great looking insects and flowers I have opted for an old candle. Or rather a candle wick. Enjoy.
