Can anyone clarify for me the various terms used to describe depth of field?
There are so many it's hard without a photo dictionary to relate in my head what's actually being said to me about the matter...

As I understand it here are the two extremes:

1. what terms are used for no depth of field images (where everything is in perfect focus)?
2. what terms are used for super small depth of field (where the nose is in focus and ears are blurry, background blurry and some foreground if present is blurry)?

And what lens settings are used to obtain these two effects?
