Or shallow depth of field? I have been struggling with this latest assignment for the photo club. I am not sure of the difference between the two. I tend to think of selective focus more as the whole subject is in sharp focus compared to the rest of the image which has some degree of blurriness but enough to recognize some elements that tie into the subject. So, with that interpretation, since the tree frog's eyes are really the only sharp part of the images posted today, I don't think they are selective focus. It will be interesting to see how the judges interpret this assignment.
Camera info: Nikon D200, 60mm macro lens with closeup filter attached (+1 or +4, can't remember which filter) at f3.2 and 1/80th, ISO 400, Cloudy whitebalance
Post processing: In ACR processed for more exposure and blacks. In Photoshop, used Luminizer from Kubota or levels for global brightness, Touch of Light if needed, sharpened with the Edge or Popsickle from Kubota
