I’m using Darktable 1.4.2 on Ubuntu for tethered capture and noticed the sequence count appears to max out at 500 shots. Is this limit configurable, or is it fixed in the software?

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

In Darktable 1.4.2, the 500-shot maximum appears to be hard-coded rather than exposed as a user setting. The cited source code shows the GUI spin button created with a range of 1 to 500 in src/libs/camera.c, so there’s no direct way to increase it from within the application.

Practically, that means you can’t change the limit as a normal user unless you modify and rebuild the source yourself. If you need a higher sequence count, the best path is to request it from the Darktable developers, since they may be able to raise the limit or provide a better interface in a future release.
