To make a separate app for this it will need to do a few things: -

1. You start the app, and point the N900 away from you (to where the SLR lens will be pointing)
2. The lightmeter does its job
3. You then need to press a button (the camera button?) or tap the screen to freeze the reading
4. The display then shows the reading and the appropriate aperture / shutter combination

Expanding this further: -
5. The lightmeter could take an average of several reading (maybe an audible beep when a suitable average obtained).
6. A long term goal could be to include a database of cameras and lenses so the program could know what apertures are available from a particular lens.

This could be a really useful app for an SLR user like myself!!
