The original transparency was rather bland, with a weak blue sky and untinteresting colours, so, after scanning it, I desaturated the image and then colourised it in Photoshop.
My viewpoint for this shot was the middle of the road, just below the brow of a hill. Although I had plenty of time to get out of the way of vehicles approaching in front of me those coming from behind me gave little warning.
The road was not very busy but there was a constant flow of traffic and, apart from self preservation, my main concern was to ensure that any vehicles in the shot were as distant as possible and that there were not too many of them.
I also wanted to get to the valley in time for the evening light, but it was closed when I arrived. I guess, with a little patience, I could removed one or more of the vehicles, but it does not seem very important to me.
This is beautiful Michael. I wouldn't have guessed it had much manipulation in PS. The lighting was working right for you and great perspective. I assume you were at the top of the next hill on the road? Were you out of your car? If so, pretty daring of you - I'm sure those cars are coming up fast! I'm enjoying your photos. Glad you joined the site. Looking forward to seeing more from you and learning. Anne :)
