Yep. This is all original stuff folks. Nothing has been added in at all. It's not something I do! All I have done is add in a little fill light and lighten it a little.
On Tuesday morning, the contrast was very high and so 4 stops of grad were used to control it. Unfortunately, this can cut into an image. However, it is conditions like this that make HDR near impossible as you are being buffeted by the wind. The possibility of camera shake is very high. This accounts for the higher than normal ISO.
Glad you all enjoyed it
PS Going back to the sky. I couldn't believe my luck when it cracked open like that. It didn't last long though!
