Earlier in spring this Year, we were surprised to see a mother duck with 5 ducklings on our street as we have no nearby lake or ponds. While I was worried about the ducklings, I ran in house and got my photo gear to capture the touring family. As it was pretty late in the evening, I used a 70-300mm at 300mm and had to take few sample shots to get the ASA and 430EX intensity correct. The results are quite pleasing including graininess of 800ASA.
