How to trigger camera when reaching destination
I would like to know what component I should use to fly a drone over specific waypoints, get stationnary, take a picture, move to the next way point, etc. So far I tried to use the destination component but the triggering of the camera happens while the drone is on its way to the destination. As I am flying at very low altitude, I need to have the drone stationnary to avoid motion blur.

You can just put a list after the Destination component, or as part of the achievement inside of your destination. Feel free to share a collaboration link to your mission plan if you want me to show you.
Thanks, that makes sense, and it works fine. I added a 1 second wait with automatic camera trigger.
A follow-up question: I am using the orbit function to take photos around a point, which we will then make into an orthomosaic. It is low altitude, 2.5 m, 1-m orbit radius, and slow orbit speed (1.5 kph). In the simulated flight it takes 7 photos on each orbit, however when I do the mission in the field it only takes 2 photos, which is not enough for the photomosaic. Could you suggest a possible explanation?
FWIW: To add to your first question re: stationary photos, this is my primary use of DL. I make use of the Path component in combination with Simulated Drone to frame the shot I want. When I get the desired camera look I select "New Waypoint and Marker" to secure the camera/gimbal/elevation position and then simply add my List of desired camera commands. If I want to continue and go to another shot I add another Path at that point and go to the next location and repeat the Simulated Drone process. This allows me to take multiple photos from many different angles all in one Mission.
The 2nd option in this video introduced me to this technique and has proven to be easy to do and gets me the photos I want. And, it is repeatable!

Please share a link to your mission plan.
David White, thanks for the tip.
Jim McAndrew, here is the link: https://app.dronelink.com/david-parsons-8ExOcPzAFm9ciIOrsHiS/test-folder/plan/ukcdIDXGPufIvm6xRSW8/UINoWkYrq3zRkdZEQN2v
My guess is you are asking the drone and flight controller for more precision than is possible. The position sensors are +/- 4m (GPS and barometric altimeter), so operating well below those margins is going to be difficult, impossible, or inconsistent at best - unless you switch to using an RTK drone.
