This Mute Swan swam up to where I was sitting. I could not get the whole swan so I shot 2 shots quickly handheld to combine into a final image. Then as it got closer I tried 3 shots and 4 shots. I usually see my subjects farther away so when they come close it is fun to try combing images. Also you get a large file with lots of detail for large prints or severe cropping. I use Photoshop just because I tend to like to do other touchups and sharpening at the same time. Friends like Zerene Stacker, Helicon Focus and there are even some free ones if you search online.
