    Question reading and setting shutter speed possible for Nokia 808?

    Dear everyone,

    I would like to change the qtcamera example to a somewhat better camera application
    for nokia 808, or, to add PASM modes and focus control to the application.

    Anyhow, when I tried to read shutterspeed from qcamera->exposure()->shutterSpeed()
    it always return a zero.

    Actually, is it possible to read shutterspeed value from qcamera ?

    br,

    Everyone would like to get a camera with better control to 808...

    What is possible with QCamera seems to depend on the device. Your wish for ASM will not be realized, as the camera in 808 has only one aperture (plus a ND filter, for which there doesn't seem exist any Qt API), so there is not that many possibilities for adjustment. Setting shutter speed does not work, nor does apparently reading it.

    The same applies to focus control. Only focus mode that works (according to what the isSupported calls report) is auto focus with no control even to the focus point location.

    Dear mvuori,

    Thanks for your quick reply in confirming my test.
    Should I instead look for ECAM api to control the camera ?

    BR,
