Controlling Depth of Field in Macro Shots
Depth of field in macro photography is one of the most significant aspects that makes macro photography difficult. In some cases, this can lead to the majority of your subject ending up soft.
Photography 101 tells us that the smaller the iris, the greater the depth of field. If you are photographing a static object, then you can easily use a slow shutter speed in order to get an exposure with an F 16. If you go this route, make sure you use a tripod to minimize motion blur. The other avenue to explore is increasing the amount of light on the object. A diffuse light source placed strategically will not only help with your focus issues, but can also increase the quality of your image.
You have set up your shot so that the object fills the frame of the macro image. However, you still have a drastic range of focus to deal with. Consider moving the camera back and cropping the image later in Photoshop. This will reduce the resolution, but perhaps the sacrifice is worth the extra depth of field.
Focusing can get tricky in macro photography, but these steps can alleviate some of the stress.Popular Cameras for High Quality Photos:
