Thanks Glen, Cam, and Jo.
Glen, I don't know about you, but after my first full length sub
I magnify the screen to it's max to check for trailing, and about half way through the series I do it again to check that focus hasn't changed. I am working on a crude home made cooler box so that I can hopefully continue to use 1600 through the
summer. I seem to recall hearing somewhere that once you get over about 5 mins, diminishing returns start to creep in; I
wouldn't know from experience, having never tried anything over 2 mins since leaving film behind.
