Tethered shooting with digikam, and thumbs

[Anders Lund]

Hi list,

I read lots of photo articles recently, and came to read about tethered
shooting. Of cause I immediately thought that would be possible with digikam
;)

So I connected my canon eos 7d, and started to look. What I found is that in
the import window, in the "device" menu there is a menu item indicating that
this is possible.

However, it does not work. What happens is that the mirror appears to be
opened, but not closed again, and no image is captured. A small dialog
appears, with "help", "capture" and "cancel" buttons. Help have no information
about this issue, "capture" appears to close the camera mirror and then open
it again, while "cancel" seems to do nothing.

Dummy thumbs appears in the window, but they can not be displayed or
downloaded.

Now, did anyone ever try this, and maybe even experience succes with it?

As part of my exploring, I clicked the device->information menu item, which
shows information about my camera - maybe from gphoto? This dialog indicates
that it should be possible to get thumbnails from my in camera photos, and
that capturing images using gphoto should be possible. This of cause reminds
me that there are no thumbs in the import dialog, and I really wonder why this
have not been fixed, an issue for as long as I can remember.

Is the missing thumbs in the import dialog a canon specific problem? Or does
any canon dslr users actually have thumbnails? And what about users of other
camera brands?

Anders,

I implemented this feature few year ago using an old Olympus C3030Z
which is supported tethering through GPhoto2.

This device is dead now. My new Sony camera only support PTP protocol
through Gphoto and tethering do not work.

So, i cannot debug this part actually...

Hi Gilles,

Just for the fun, I will install gphoto2 and see if it works using the cli
interface. Reports follow when I have some results.... :)

Ok, a short follow up:

I can do tethered shooting with gphoto2, simply

$ gphoto2 --capture-tethered

This will download each image to the current folder, and delete it from the
camera. A script can be called to display the image, that is yet to do, since
I shoot in RAW. Gwenview can not display thumbs from my RAW images, it seems.
I could use showfoto, but that would cause the images to be converted, which
takes time.

Maybe it is possible to use dbus to show the images in digikam or showfoto as
they are shot. It would be fun to have the option inside digikam, and images
renamed and put into folder as desired by user, and of course displayed as
shot.

Using gphoto2, I can also capture an image immediately, or capture-and-
download:

$ gphoto2 --capture-image
$ gphoto2 --capture-image-and-download

This means that the capture menu item should be fixable, I believe.

The preview fetching does not do anything, trying it, I get something like
this:

[anders@kamelon t]$ gphoto2 --get-thumbnail 3
Hjemhenter 'IMG_2890.CR2' fra mappe '/store_00010001/DCIM/129EOS7D'...        
Hjemhenter 'IMG_2890.CR2' fra mappe '/store_00010001/DCIM/129EOS7D'...

("Hjemhenter" means something like fetching). But no file is available in the
cwd after that.

So maybe digikam isn't alone having this problem...

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 :)
