Processing remarks	Warning: image file 1: automatic white balance can cause inaccuracies. image file 1: Note: image seems to be noisy. Try reducing the ISO setting or increasing the exposure time. Note: image file 1: suggested exposure time: 1/110 s (Set EV to -1.4) Warning: image file 2: exposure time below 1/500 sec is unreliable. Try increasing the EV compensation. Warning: image file 2: automatic white balance can cause inaccuracies.

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.
