When I try to use the night sky setting in my camera (nikon d3000), it doesn't take the picture, or says subject is too dark. I'm totally new to this so should I be doing something different? thanks.
Added (1). It will not let me change the settings of the shutter speed, it says that it is not possible to change under the settings, even though i had everything else
>>> DSLR/NIKON D300/NIGHT SKY SHOTS?
