I just bought a Nikkor 50mm 1.4 lens and I'm not getting the shots I want. I think I have the wrong settings. What setting should I be using, cause these photo's are obviously not sharp what so ever. I do have a SB 600 flash with a flash cord. If need to use it, what do you guys think it should be set at looking at these photo? What correction gel might I have to use? I am going back to shoot more tomorrow so please reply quick! None of these photo's have been edited. I'm using a Nikon D80/. 1. Why are these so over exposed? It seem somewhat dark. Settings were F1.8 ISO 100, 1/15. 2. Settings were F2.5, ISO 160, 1/13. 3. Settings were F1.8, ISO 160, 1/40. 4. Extremely over exposed, but why? F.18, ISO 160, 1/50. 5. Dark shadows on her face. Should I use a flash? If so where should it be pointed? Settings were, F1.4, ISO1 160, 1/40. 6. This one was out of focus. F1.4, ISO 160, 1/40.
