I was shooting some macro shots this weekend and I'm struggling with getting the whole image, in this case flowers in focus. I'm using a Canon 100MM F/2.8 lens. I'm shooting at about a 22-29 aperture. I am getting pretty close and using a tripod and lighting. I'm curious on how others are getting these shots. It seems like my DOF is too shallow and I'm only getting part of the flower, (middle) in focus and not the whole thing. Do I need to back off the flower some and then crop and zoom in photoshop to make larger? Thank you.
