More pos than photos,what happened?

cry to help!

In one sortie flight,ardupilot recorded 146 POSs,but only 141 pictures,How do I handle it?

Hard to guess which images are missing.

In future use a camera feedback pin so that you are logging a confirmation from the camera each time it is triggered.
