Such a glowering sky! Are you sure the birds didn't take off due to what looks like the impending storm?! I can see they've left their mark, for sure. The effect of the lightbulb glowing plays off the bird droppings and helps with the contrast against that dark sky.
oh wow, the darkness and moodyness (is that a word) work perfectly on this monitor!
Looks like there's just enough of the silvery, hurts-your-eyes-to-look at light of the sun shining through some medium dark clouds somewhere in the distance, to give the equipment a glow and make it stand out just enough against the dark sky... I really, really love it! The little lamp fighting all that darkness in vain makes it even better. I say again, wow!
You're right, I am a sucker for darkness in my images. I love using negative space and underexposing to add to the mood. This one is almost too dark for me though, I was in the process of giving a bit more light to the centre pivot tower when my wife walked in and commented on how much she loved this shot. Hence I stopped right there - happy wife, happy life .
