As a fledgling BIF photographer, I am trying to follow and find slower shorebirds in my camera’s viewfinder. Attached are some of my efforts. The third photo I find almost unpleasant to view because of the excessive depth of field. Would I have lost sharpness if I had increased my aperture setting or could I do some post processing in Lightroom to blur/change the backround? I hope this isn’t too elementary of a question. I am often reluctant to post because I am so impressed with the photos I am able to view. Any comments would be welcomed.
