I have started doing a little more HDR photography, especially with my landscapes. I am wondering how many bracketed shots other people feel is necessary for optimum results. In doing some research I have read the "more is always better" argument in favor of nine shots, but since I have started shooting with a D800E that means almost 500 MB for each. That eats up memory cards pretty quickly if I am out shooting for the day. I recently did a little experiment with a landscape where I had taken nine shots with one stop between each. I then used Nik HDR 2 to process using all nine, then seven, five and finally three shots. What I found surprised me a little. I found that, at least for that scene, that five looked best to me. Using nine and seven shots took away some detail from the clouds in the particular scene while not handling shadow details in the trees significantly better than five. Three was least pleasing to my eye although it too was very good. One of the complaints from some D600 users has been that it will take a maximum of only three shots using the BKT function. I know that it is "in the eye of the beholder", but I was just wondering how many shots others are using for HDR photography.
