Many Thanks Craig, no contest mate, it is one subject that I have never imaged ans I was determined this to to have a good go at it, I feel it turned out OK, and never really considered 800 ISO.
I sort of have a set procedure, at no more than a 7 mins sub on any subject, and consider the ISO according to the temp, but i do like it at 400, so I have to capture more frames to get the same result of 800.
Don't know if this makes sense, but if one keeps chopping and changeing settings, one would never know where the balance is.
