Auto exposure settings changes the aperture instead of favouring shutter speed. Considering lower shutter speed results in ground blur, not having the ability to have a shutter priority option seems strange. I don’t use auto modes because of the consistent ground blur, even in sunny weather.
Manual settings are my favoured option but as I discovered yesterday, over exposed roofs and then cloud cover under exposing ground shadows near trees is a tricky thing to combat without auto exposure. I understand setting DD to use manual camera options then using DJI Go app to set shutter priority would work, but as an all in one solution, shutter priority should be a usable option in DD.
