I know what appature does, but im not sure which way round the scale goes. What I mean is does a higher F number mean the whole picture is more crisp or does it mean it will blurr the background out?

Also what is a good high and low number to use as I dont want to make my pictures two blury as the scale seems quite wide.

Low F-value (for instance F/2.8 ) = blurry background.
For what is good and bad, i would recommend to figure that out for yourself by trying a lot of different stuff :-)

Hi tobywuk,

If you have a little time to devote to some study there's a good "Understanding Depth of Field in Photography" tutorial at the CambridgeInColour site.

Bob.

It's easy: the f-number is directly proportional to the depth of field!
So higher numbers mean greater dof...
