This photo is quite dark in the lower left corner... kind of unavoidable though, since the only light source was the light pollution you can see from the city you can see. There was a moon, but the high overcast sky meant that you couldn't even see it.
HDR from me, i think i posted this earlier in B&W but i think it works better in colour. bit of ghosting in the trees in the background, it was damn windy so that was unavoidable....saddly my skills on computer do not extend to removing them but i think it add's more to the DOF.
quite pleased with it really, its not over done like a lot of HDR's, its not too obvious. i think you'd need to see the 0EV exposure to see the difference. no haloing and its brought out the bark detail nicely!
