My first experimentation with a 10 stop ND filter. Things that I learned:-
1) On a bright sunny day you can't see what you're looking at through the viewfinder, so an opaque, dark cloth is a good idea to cover your head and the camera. Luckily I had a baggy top that I could pull forward over it.
2) Luckily, my autofocus was spot-on, even though I couldn't see much!
3) In bright sunshine, at 100 ISO, I was getting about 5sec at f/22.
4) This picture was taken without using the camera/head cover, which affected the exposure and the colour balance. Later shots where I used my top, the results were better. I suspect that light was finding it easier to enter through the viewfinder than the lens and this skewed the camera's sensors.
