Nice work C.H. I noticed that some say "ISO 80" and some say "ISO 160"
which leads me to a question I've been meaning to ask for some time.
What in blazes does it mean to have multiple ISO speed ratings on a
digital camera?
With film we'd be trading off something like grain or less accurate
color for the sake of increased speed. What are we trading off with
digital? resolution? What's actually happening... pixel combining to
increase sensitivity or some such thing?
