My daughter asked me to take pictures at the hospital when she has her baby, my first grandchild. I have a canon T3i with 3 lens to choose from: 18-55mm 4.5, a 50mm 1.4, and a 55-250mm 4.0. I want to give her some awesome photos. I would like to know what lens I should use and what would be the best settings? Thank you.
