I have a list of suggestions for the GstPhotography API.
Currently the GstPhotography interface has functions for
querying the value and setting the value of the different properties.

The suggestion is that it would be good to have interfaces for
querying other things from the properties in GstPhotography.
This is an example of the functions that would be needed,
using the exposure value as the place holder.

gboolean gst_photography_maximum_exposure(GstPhotography * photo, guint32 *
max_exposure);
gboolean gst_photography_minimum_exposure(GstPhotography * photo, guint32 *
min_exposure);
gboolean gst_photography_step_exposure(GstPhotography * photo, guint32 *
step_exposure);
gboolean gst_photography_default_exposure(GstPhotography * photo, guint32 *
default_exposure);

Also, the notifications from value changes would be very useful - I still
haven't
learned enough of the Gstreamer internals to provide suggestions for
implementing them, though.

If you can think of a better way of querying the value ranges, please consider
it, too. This is just one suggestion.
