Warning: image file 1: Underexposed. Please increase the shutter time.
Note: image file 1: suggested exposure time: 1.6 s (Set EV to +0.7)
Warning: image file 2: exposure time below 1/500 sec is unreliable. Try increasing the EV compensation.

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.
