You can correct a lot of problems in a digital image with photoshop. But you can't transform an image captured in bad light into a good photograph. Unless, of course, you are looking for some funky, stylized look.
For these images of Julie the light on the beach was darn near perfect. Typically at 10:15 in the morning the light would have been too bright and harsh for good portrait shots. But the storm clouds brought some ideal conditions, at least for about 15 minutes. I almost missed it. I was taking some shots of the storm on the beach, when Julie and Becky walked by me toward the waterfront. I was heading back inside when I looked back at them and realized how ideal the light was.
If you want to capture good to great images, learn about the light. Ignore the camera companies. It's not about how many megapixels your camera can swallow. I should also say that these images of Julie were captured with my so-so Nikon 18-200mm lens. It's not a very good portrait lens. But I didn't have access to my Nikon 105mm or even my 55mm or 35mm prime lenses. You use what you have. The quality of light is more important than the camera or lens (assuming, of course, you do have something better than a cell phone camera).
