I am new to drones and I am sure that this has been covered in previous post, so please forgive me. However, I have been trying to take pictures of waterfalls utilizing my Mavic Air, but I can only get the shutter speed down to 1/50 before everything starts to blow out. However, this is proving to not be long enough to get the effect that I am looking for. Any thoughts as to how to get this better? Thanks for the help and insight.
