Hi Lynn! Cloning is a personal decision that every photographer must make for him/herself. Some refuse to do it, which is fine...others do it, which is also fine. There is no right or wrong answer. If you decide not to then you can always "scout" for individuals that are in better condition or without fuzz or other imperfections (that includes pluamge condition...this one looks a little ratty in mid-molt). Easier to do with tame "park" mallards than with other types of birds. Anyways, good job with the exposure and the details look great! Nice background. I'm wondering if you could have moved right to eliminate the OOF ducks at the right edge?
