Re: python capture_preview speed

Another related question. Does
 anyone have experience running python gphoto2 in a separate thread? I haw
little if any experience with threads. My Idea was to run gphoto in a
separate thread and then exchange data with GUI, not sure if it is a
correct approach.
Best regards.
Petro.
