fmg Taking the exposure to the limit, we continue with the marks in burnt areas, Sony a7r2 camera.
Looks like saturated pixels are not handled properly by ASIAIR. The cyan artifacts look suspiciously like saturated red pixels have numerically wrapped around to zero, but the green and blue have not yet saturated. While the red artifacts look like green and blue have saturated.
It is either a bug in Preview (how data from the camera are scaled to 8-bit RGB when displaying to the screen --for example, not truncating RGB values that are over 255 [for example, masking with 0xff, instead of a comparison with 255]), or it could be a bug when converting a 14 bit image into a 16 bit image.
You can try to save the image (that download icon below the exposure value) to the tablet's photo album. If that image is OK, the bug is just in Preview, and your images actually survive, so you can just ignore the blemish on the screen.
