I'm sure you know this, but a friendly tip in case you didn't.
Vitally important is to close the viewfinder blind and I even cover the plastic distance guide lens perpex viewer for exposures over about 45 secs. If you don't light will creep in and then you will be at risk of banding. See the before and after images below as an example. In image 1 you can see the tripod shadow which means the viewfinder was pointing towards the sun. Image two the blind is closed and the distance scale taped off. Both 60 secs @ f22 exposure time.
Only thought I'd mention it as it confused me, even I thought I had the viewfinder blind closed, it was sticking half open! I even wrote to Digital Camera Magazine who published my query and they told me about the possibility in bright sunlight that the distance scale should be masked off too.
