Hello PandaFlyingCat! I need some advise for night long exposure drone photography. I need to take a long exposure of a 2 minutes performance in the ground that will be done with torches. The idea is that the aerial camera should record the trails of light left by the torches held by people. I am going to purchase a drone from dji for this project. One of the challenges is that this process would repeat multiple times during a few nights and I would need to find a drone which allows me to pre-programme a sequence of of taking-off, getting into a fix position and shooting the long exposure photograph. Do you know any way of creating an automation on a drone? Which model would you recommend me? My budget is up to USD10,000. Based on your recommendations for night photography I assume I would need to take 60 photos of 2s exposure time and then merge them together in PS. Is this correct?
hm... i dont use DJI for these things but a P4A should be enough for this task.
get on altitude, shoot one photo at evening when you have a little daylight left to get a nice image from the ground without any people on. thats your reference picture where you add layers on in PS later.
if the performance start with torches you start same place where you got the reference photo before, get on same altitude and shoot multiple photos on ISO 100, f/5-8, and max exposure time the P4 allow (should be 8 seconds if i remember right) to get the light trails only without the ground getting too bright. if ground gets too bright you set up higher f/ stops a bit until you see only light trails.
use PS, add your main picture.
then open all nice light trail photos, select ALL, copy, go to reference photo, paste and choose MULTIPLY LIGHTS for this layer. repeat with rest trail photos until you satisfied with result.
with this method you can add many layers over your ground photo and only adding light sources.
i doubt that it will look amazing but you can do some test runs before the show to get settings right. city with moving cars should be a good place to learn
