Thanks everyone. Shot #1 is just an exercise in negative clarity to soften the already soft shot of the bluebells waving in the breeze. I must have looked daft lying on the ground with camera on tripod, 70-200 lens, close up lens on front taking shots of bluebells a few cm in front of me, luckily it hadn't rained for over a week so the ground was dry.
Brandt you are probably correct about the vignetting on #3 it will need to be backed off a lot when I print it. For some reason I had applied 10 points of clarity to #2, this one has some negative clarity applied to the foreground. I just like the shape of the tree and the blossom on it but trying to shoot it without crushing the bluebells was difficult. Unfortunately I get seduced by contrast and detail all over and need to stop doing it everytime.
