I'm using Darktable 1.4.2 on Ubuntu to take a sequence of photographs, but it seems the maximum count I can set is 500. Is there a way to change this?
The limit of 500 is hard-coded into the source:
lib->gui.sb2 = gtk_spin_button_new_with_range(1, 500, 1);
In file src/libs/camera.c Line 443.
The commit message doesn't provide any reasoning for limiting it to 500. As a user there's nothing you can do directly, but you could send the development team a note that you'd like to be able to sequence more than 500 shots and see if they can provide a better method for making that selection in a future release. The best way to do so is probably to sign up for the Darktable mailing list and then submit your request there: https://lists.sourceforge.net/lists/listinfo/darktable-users
