[Digikam-users] Tethered shooting with digikam, and thumbs

Hi there,

Some news on this issue: I tried today just using gphoto to shoot tethered 
inside a directory in the digikam collection, and that worked fine. 

Simply:


$ mkdir Pictures/tethertest
$ cd Pictures/tethertest

Now, start digikam and navigate to this directory, and connect the camera to 
the pc.

$ gphoto2 --capture-tethered

Shoot, and digikam automatically sees the new images, and they can be browsed 
and edited as normal.

This is very nice, what is missing is automatic preview display of each new 
image, and of course control from within digikam, including a naming pattern. 
But in fact, this is a usable solution, even using cli - you just have to 
create directories, move digikam to the desired directory and call gphoto 
manually from within there.

I also tried with showfoto, but it fails to autoshow the images.

I also installed darktable, which have a very nice tethering support. There is 
an option to start a tethered session from the gui, and in addition to 
creating a directory (I believe), it also allows to control my camera 
settings, and immediately displays a preview.

I think something similar would be very cool for digikam, and getting started 
- just create an album and provide naming patterns for albums and images, and 
start the tethered session would be a great start!

Kindly,

Anders
A very happy digikam user :)
