Summary: more documentation on unplugging camera

Initial Comment:
it would be very nice to have documentation on how to
unplug the camera after using gtkam (and, of course,
not unplugging it while transferring pictures). 

filesystems needs to be unmounted in linux. from
documentation, it is not clear whether you need to
unmount your camera before unplugging it. it is also
unclear how to unmount it, if you need to. 

reasearching, I found this:
http://www.linuxworld.com.au/index.php/id;298681864;fp;2;fpid;37

where it says: "When you're done using gPhoto, remember
to turn your camera off before disconnecting it from
your computer." So do we need to turn it off before
unplugging? 

Whether we need to turn it off (or unmount it somehow
(have no idea how), documentation (at least the man
page)  needs to show that to the end user. 

Thanks.

Uhm, yes -> even that would be enough "Do not be afraid to
unplug the camera now."

When using gphoto ... well, you can just disconnect the 
camera after use. 
 
I guess the documentation needs to suggest: 
 
"Do not be afraid to unplug the camera now."

The camera I am using (Canon Powershot G6, which caused me
to look at this issue) is not seen as a storage device. But
gtkam can transfer images from it though. 

Above article says that you have to power off the camera
before uplugging when you are done. It does not mention
filesystems (therefor my confusion, and the lack of
documentation in gtkam). 

My point is: gtkam documentation is fine when it comes to
initiating communication, but lacks advisories on what to do
after you are done with the camera. Such as:
-unmount it if it is mounted as a filesystem
-turn it off before disconnecting if it is not recognized as
a filesystem. 
-if you do not do one of these, you may loose you data on
your camera.

Lack of documentation is confusing as well. The link above
says "power off before unplugging"; you are saying "you
don't need to do anything, just unplug it" (if I understand
correctly); and the documentation does not address this at all. 

thanks for the reply and fixing the category (to feature
request).

I just read the article. I don't see your point.

If the camera is a USB storage camera, then yes, you should
be unmounting it. But it is because of the way filesystem
works in Linux.

As for camera you use with gtkam, there is nothing special
to do...
