Processing remarks	Warning: using the flash makes no sense. Warning: image file 1: could not determine angle of view; assuming 38 mm lens (35 mm equivalent). image file 1: Warning: image includes screen edges or something that's not a monitor. Hold the camera close to the screen. Warning: image file 2: could not determine angle of view; assuming 38 mm lens (35 mm equivalent). image file 2: Warning: image includes screen edges or something that's not a monitor. Hold the camera close to the screen. Warning: using the flash makes no sense. Warning: image file 3: could not determine angle of view; assuming 38 mm lens (35 mm equivalent). image file 3: Warning: image includes screen edges or something that's not a monitor. Hold the camera close to the screen. Warning: Image focal lengths/zoom levels are not the same. Warning: image file 3 is too bright to be a dark photo. Maybe you mixed up the files?

The luminance values in cd/m2 are not very reliable, since camera sensitivities can easily differ up to 50% from their nominal value. Typically, the real luminance is 30% lower than this number. The area used for calculation is chosen such that it corresponds to a viewing angle of ±14° horizontally and ±10.5° vertically, which is equivalent to viewing the screen from a distance of about 1.5 times the diagonal size.

Unfortunately, there is a lot of variation in how cameras use EXIF settings. If photos from your camera your produce unusable results, try coming back in a few days. I review submitted pictures regularly and try to fix problems.
