Hi all, We have recently got a Phantom 4 RTK but we are facing an issue of image overexposure. I have searched on the Internet but didn't find any related threads. I am wondering whether this is an isolated issue.
I have done five surveying flights with different camera settings but these images seemed all overexposed. The test was on a sunny day with 37 m's flight height. The white balance was 'sunny' and shutter speed settings of these flights are auto, 1/1600, 1/1250, 1/1000, and 1/800 second. Here are some snapshots of 100% zoom of images.

AFAIK, we cannot change the EV settings when running the survey mission and the camera settings in the FPV interface is not related to that in the survey mission. Is this issue caused by malfunction of the camera or I can change some other settings to make it better?

I also noticed the overexposure issue.  If you change to the camera view fullscreen while in a mission,  you can access controls that allow you to set the exposure value.  I'm defaulting to -.3 for now but may go to -.7 on sunny days.

Hi,

Mayby a little bit late to answer but nevertheless.
I've been doing a lot of survey with my Inspire 2. The camera isn't that much different than the P4. I'd overexposure issues as well.
On really bright sunny days I use an ND filter. i've noticed that the images are way better this way. Mostly ND 8of ND16 will do the trick.
