Dear Nikolaï,Thank you for your comment, with Photoshop I have just adjust the light and the sharpness, and the grey tones, as you know with the Nikon D70, is too under exposed, the colors are natural is this area, that's the reason I have made the picture.
The problem of being "over blurred", is a compression problem : max 150ko... with trees and flowers, you loose a lot of information.
The original is more than 7mo. in 300DPI...
Thanks again for your comment.
I agree with you, Photoshop is to be used very slightly.
