Will shooting on f8 or 11 better the files sharpness I am shooting with a Nikon d100. Mostly on p setting auto and I feel that the pictures are always not as sharp as I want. I believe this is built in I also believe they have a built in slight under exposure feature to avoid blown highlights. If I shoot on F8 or 11 On A setting will the images be sharper. I like shallow depth of field but never feel like I have a super sharp image. Do I have to depend on my film cameras for image quality and shoot with the digital as back up or as a film money saving tool.
