Drilling for..whatever...this is a great image. The fantastic blue sky builds a perfectly contrasting background... and the white cloud looks like there was steam coming up the drilling hole....a great composition with very good detail in your shot.
High marks from me for this outstanding picture....

Now at last some technical hints in this site otherwise filled with arts ..! LOL
Seriously I mean this is so refreshing and besides I agree with Bernie above ... 10/10.

Very cool photograph, I like the contrast between the silhouette of heavy machinery against the clear, blue sky, and the poofy, white clouds. Very good job!!..=)

Great contrasts - very nice and sharp silouette image. Did they find something...?

I find this picture great J, it reminds me of the pit head winding gear that used to dot the skyline in my part of the world. Sadly, there are no coal mines here any more. TY
