In the beginning, I was getting reasonably sharp images from the spark camera. Over time the images taken by camera have gotten quite blurry, What have others found to be the cause?
Sorry! I'm a relatively new drone owner. I was judging the photos by what I was seeing on my smartphone. I didn't know or forgot that those are of lower quality. Everything looks good when viewing the SD card original files. Thanks for setting me on the correct path!
A mistake I sometimes make is setting the exposure by how it looks on the phone. Phone screen is not bright enough for that! Set exposure by the histogram.
