I recently purchased a pass to the zoo. I took these 2 pics and I was wondering what I need to do to clean them up/take better pics in the future. Everything was taken in manual mode. I used a 300mm f/4.5 manual focus AI lens on my d70. Shutterspeed was around 640-800 or so, and the pictures were taken handheld. Aperture was set wide open. Any tips for going to the zoo?--I already purchased a monopod. I have a tripod but I didn't feel like lugging it around. Any wildlife tips would help immensely. Thanks for looking!
