Why Does the Exposure Compensation Blink?

You may have noticed that the Ev meter is blinking and your camera stopped taking pictures. This can be frustrating at best.

It blinks because you are outside of the good exposure limits. On some cameras it will blink at -2 or at +2. On others at -3 or at +3.

The former is not all that wide a range of Ev so that the blinking is an obstacle to getting a wide dynamic range for an HDR series (which later are merged).

The later is really no big deal because +3 and -3 captures a set with a great deal of over and under exposures, provided you have other shots in the series that have Ev values closer to 0.

The Ev blinking keeps you from taking shots in the Av (Aperture Priority) mode. If you want shots for your HDR photos with a greater dynamic range, take more of them at values lower and higher than the Ev range on your camera. You can do this by shooting in Manual mode. In that mode, cameras will shoot with blinking Ev meters.
