Trouble with Nikon D700 about python-gphoto2 HOT 5 CLOSED

I think this is a problem with libgphoto2 itself, rather than the Python interface, so you might get more help from the gphoto2 user mailing list. I did a quick web search and found this (http://gphoto-software.10949.n7.nabble.com/Switching-back-to-ive-view-mode-after-image-capture-RTIAcquire-td15391.html) which sounds similar to your problem.

Have you tried it without exiting the first camera & context, i.e. carry on using the same camera and context for the second capture? Alternatively, have you tried deleting the first camera and context objects as soon as they are finished with?

The link you gave don't give the answer ... just a similar problem :(

And yes I try to make with one "camera" and one "context" but I have the same problem ...

What's "deleting" ? I used the gp_camera_exit function wich is made for, not ?

from python-gphoto2.

The lack of an answer is why I don't have an answer.

gp_camera_exit releases the camera (only one program can control a camera at any one time) but the camera and context objects (and the C structs they are proxies of) still exist. The Python del statement can be used to delete them, freeing up any resources they are holding on to.

I found a solution on the net : make a Time.sleep(0,05) and its good !!

But when i try to make a real capture the focus is not make ....

And idea ?

Thank you !

I've not done any capturing with my Canon cameras, and have no experience with Nikon. Have you tried doing what you want with the gphoto2 command line tool? If that works then you'll know it's possible and you just have to find the magic combination of libgphoto2 calls that's needed.
