Here are two pictures,
The first one unedited other than cropping the second the brightness adjusted on it..
Yes the second one looks far more dramatic, but I have to say there was no challenge or satisfaction in producing the second one, it also looks nothing like the cloud did to the eye.
Enhancing pics is great fun I can't deny that, its nice to see what you could have got, but to me the real enjoyment of photography is seeing something you think would look good, and getting that shot. As I did with my lasses picture, she was just sat there looking all moody and grumpy because I wasn't taking any notice as I was mucking about with the camera, thought that would make a great shot, snap very happy louby!
