Each time the EV decreases by 1, the light it represents is halved. There's really nothing significant about 0, hence nothing really significant about negative numbers other than that they represent dark subjects. The EV scale theoretically goes to infinity and negative infinity. Complete and total darkness (0 photons) would be negative infinity. Of course, such complete darkness doesn't exist. -- Victor

Cool, I think I've got the only image with a negative EV value so far. :) Now, um...what does that mean exactly? Olaf: Good point, I didn't even think of it. Next time eh? :-)

EV is -2.9 (yes, that is negative)

Anohter shot that could equally well have been in the previous challenge (perspective). The leading lines are very effective at bringing the viewer into the image. Amazing to see so much color in a night shot. The human eye stops seeing color at low light levels, but the same is not true for cameras.
