Sorry, I haven't seen your comment until now. I used a DJI Mini 3 and I must say that I didn't use pictures, but a couple of videos around the church, that they were not intented to be for gaussian splatting, but for informative videos about the Camino de Santiago in the pronvince of Palencia. You can see all the information about this project here:
