More on DoF...

[BuS_RiDeR]

There are several DoF calculators out there... But does anyone know of one that works on the Blackberry Curve? that is NOT Web based but a separate application?

I know there was a similar post to this recently, but no one pointed to a standalone Blackberry application.

Found this, but I know nothing about Blackberry or if this is a good place to download apps...

how will you establish the distance to the subject? estimation? why not estimate the desired F-number also? this seems like more superfluous techno crud. just bracket a few shots.
