I am a terribly new photography hobbyist and I am practicing to shoot my girlfriend's senior portraits in a couple months. These are my first attempts at outdoor portraits and I am not impressed with how they turned out. These shots were taken a little before sunset, Canon 40D - 50mm/1.8f. Natural light obviously. I do not plan on investing in any off camera lighting other than a reflector for the actual shoot when I have someone to help. Any help is appreciated.
