Thanks Cinder, I had totally forgotten what it stood for. I was thinking International Standard something but couldn't remember what the O stood for. Although the way it's written technically it should have been IOS. LOL

Yeah, that whole ASA thing used to throw me off in the beginning until I got it figured out that it was the same as ISO.

OMGosh that site is 'serious', WOW. Talk about high tech wording and mathmatics!

Since many people I talk to about photography only know digital I found I have to simplify things. Actually ALOT of people I talk to about photography stuff are just people who just want to get good pictures but don't know why their pix don't come out good. I usually simplify it down so I don't confuse them with too many technical things they don't understand or aren't interested in anyways.

I've gotten into the habit of simplifying my 'tech speak' so much that when I'm around very serious photographers I'm sure they think I don't know which end to point at the subject and which end to look through. LOL
