Among the many new techniques in photography I’ve tried recently is a cool way to get wonderful depth of field in a complex or large subject using multiple images. The process is called “focus stacking”, which means that you take several photos (usually on a tripod), as you focus on different areas of the subject. Then you have to blend them all together in Photoshop.
I decided to experiment with this technique after an overnight rainstorm had left a collection of dew drops on the newly opening Columbine flowers in my front yard. For this shot, I positioned the camera directly over the flower, pointed down at it, put it on manual focus, and then turned the focus ring very slightly as I clicked the shutter. Here’s the result of blending 5 images together — I probably needed more images in the stack because there are some holes in my focus, but you’ll get the idea.
