Sofobomo Chapter 2 - preparations

Preparations are a bit slow after my group photo exhibition. Work and other commitments have intruded on my photographic objectives rather rudely. I did manage to take some pictures over the weekend using my new filter, which allows blurring of motion during daylight. It's a 10 stop neutral density filter. However it still only gives me around 15 to 30 seconds of blur at midday in gentle winter light. I am having to stay around f8 in order not to pick up too much dust in focus on my sensor! From f11 onwards it becomes quite obvious and a pain to clean up, even digitally.
So far pictures have been of waves and clouds, my two favourite subjects for time and motion studies. I also tried stacking some Cokin ND filter on top of the 10 stop filter - however the mix of glass and plastic as well as the bouncing reflections meant that those images were mostly useless. I find I need another 6 stops of darkness.. but Schneider has stopped making their darker filter, and only do this 10stop one. Pity. Still, a lot of fun experimenting with this new filter, which makes it MUCH easier to work with time.

My previous exploits in this area were with polariser filters and stacked Cokin ND filter and f22 aperture at midday in a summer sun, leading to few usable images (but still I managed to get a few decent shots for my Xefina book). So from here-on in it should be easier, especially at the bookends of the day when light levels are lower and I can achieve 2 and 4 minute exposures.
