    I was busy with my daughter, so I didn't touch a line of code and (more important) I did't test if the light meter readings are OK...
    I would like to develop a wizard to add custom camera/lens configurations, and test another exposure equation I've found in wikipedia for incident-light meters, (now I use the http://www.exposurecalc.mobi/ one). I hope I'll find some spare time!!!
    Thanks for the support.

    could it be possible to control N900's flash? that could be one way to trigger lights with optical slaves....

    I've just uploaded to extras-devel the 0.1.2 release with more cameras and lenses.
    @ossipena: something like Flashlight?

    Isn't N900 flash too long to sync with a slave? (though it could trigger early and still work, assumingly, if it's strong enough)

    I'd still like to know if it would be possible to freeze the reading with e.g. a press of the camera button?
    Other than that, it is a perfect app!

    Well done!!

    I have to investigate about this, in the meanwhile you can use the "store exposure" buttons! Thanks for the hint!

    This sounds so incredibly neat, but I'm a photo newb... I read the Wikipedia article on light metering, but could someone who's more photo savvy give a basic tutorial in light metering with this app? As in, given that I already have a DSLR, when and how would I actually use this app?

    hello,

    I've tried to self-edit the camera.conf file to set-up my pentax kx.
    But now the app crashes after selecting the new configuration file in the program menu.
    I've tried a reinstall and a new installation with
    --purge option, too. But the program crashes immediately.
    How can I bring it up again?

    Thank you :-)
