[QUOTE="WayneF, post: 167741, member: 12496"] I can duplicate your original report. The reason is this: It shows insufficient light (when real dark), meaning A mode shutter cannot do any more to help it, A mode cannot match the necessary exposure. Then if you specify +EV Exposure Compensation, you are saying you want it even brighter than normal, and since it cannot even do what it had before, now it makes it even more insufficient (for your request). That seems right to me now that I see it. I have the D300 and D800, and it has to be pretty dark before camera A mode even shows that meter scale. Because, in A mode, the scale disappears whenever it is able to match exposure with any shutter speed (i.e., not underexposed). Unless the flash is up, enabled, ready to go. Which is because when flash is enabled, the Minimum Shutter Speed with Flash kicks in, typically increasing to 1/60 second in dark scenes, which is then no longer able to match the darker exposures... which is the explanation. Some models have a menu to set this Minimum Shutter Speed with Flash, but default is generally 1/60 second. Reasoning is, if using flash, we don't need 1/4 second that the ambient might have metered. But the thing to know with flash is that that this meter scale shows the ambient exposure, and is not affected by the flash or flash exposure. The TTL flash system in camera has its own invisible meter, not shown. This meter scale only shows ambient. On Nikons, Exposure Compensation affects both ambient and flash, and Flash Compensation only affects Flash. [/QUOTE]
