Study in Focusing different points of the Columbine
I shot 11 photographs of the Columbine with each shot focusing at different areas of the flower. These 11 images were then combined into software called Helicon Focus. The software combines all of the sharp part of each photograph into one image. This "focus stacking" technique is especially effective with landscape type images. To get sharper focus control, I used Live View on the camera and enlarged the area of concern by 5 times. Live View is by far the best way to do critical focusing.
