Found a bit of time. This is what I have done.
I took the original shot and used the raw converter to produce two Tiff files. One exposed for the sky the other exposed for the ground.
I the laid the ground exposed shot over the top of the sky exposed shot and deleted the sky in the ground shot. The net result is we see the sky on the bottom image but the ground from the top image.
Ideally you would take two shots of the scene, but seeing that I didn't do that I followed a tip from the "Missing Manuals for Elements 6" and used the raw convert instead.
I'm sure the same could of been achieved with levels alone, but I still need to build up experience in using levels first. If anyone wants to have ago feel free to use the posted images here.
As I explained this is a first try and was pleased, but hope better results can be achieved infuture. One thing I did notice though was that any noise became more apparent in the image after using this technique.
If you want to edit any of my images to demonstrate points/techniques to either myself or others please feel free to do so.
Still learning with Canon 40D, 28-135mm, 100-400mm L and Elements 6.
Any Advice greatfully received.
