Hi, Bob, Of course knowing exactly what f2.8 means is "doesn't mean a damn thing". Knowing that it makes a bigger hole than 3.8 is important, especially without dof preview. It's not difficult to know simply that smaller number means bigger hole.
None of my cameras say "1/1000th of a second" for that particular shutter speed. They say "1000". Is that confusing? Bigger number for shorter exposure time? I think not. I guess my point is that these numbers measure things that are so basic in photography, they are easily known by anyone who has a camera that has any manual capability at all. They make sense. They've been the standard since the earliest days of photgraphy. There's no need to change them. I don't see what they have to do with pictures of the sun going behind clouds. That's a composition issue, isn't it? Or am I missing something (not unusual <g>)? cheers, frank Bob Walkden wrote: > Of course exposure and focus are important. Getting dark?
