Hi Gary.

Thanks for the advice, I see what you mean now about there being slight detail. However, the last image with shadow detail I have is the image set at a shutter speed of 1/1000 second. I would have thought this would have no detail whatsoever as the image just appears black.

With regards to the stops, I am still a little confused. The way I am reading it, is it for example, if I set the shutter speed to 1/60 and then adjust this by 2 stops, the new shutter speed would be 1/100??

Thanks
