Inspire 1 V2.0 Model T600
Firmware: App - 3.1.68, Aircraft - 1.4.00.10+, remote - 1.7.80, basic fly safe database - 01.00.01.09

I took these photos about 6 weeks ago and am just now getting around to posting. A couple photos turned black. Many more have purple (?) dots burned in at overexposed areas.

During this flight, I used the HDR photo function, but I do not recall if HDR was active on these particular photos. I have not been able to repeat this problem.

The photos appeared fine when I checked in the app during flight. I've since learned these were the small preview thumbnails baked into the DNG.

With the black photo, the RawDigger software shows the pixels have value 0, and ExifTool shows bad values for exposure (shutter speed - 1 second, exposure time - 0). Certainly, I know I didn't set the exposure like that when I took the photos. I did intentionally underexpose some photos and overexpose others with the intent of editing them.

So what is causing this? And how can I be sure to avoid it in the future?

Thank you!
