Focus On Macro

Extreme close up photography -- macrophotography -- is difficult. Sometimes you're only dealing with a slender slice that is in focus, 1/16th of an inch or less. I recently purchased a macro sliding rail that makes focusing easier with a tripod, moving the camera and lens instead of the tripod or the subject. Now that I can shoot a number of photos with a progressive series of an object at different focus points and combine those images into one sharper image thanks to focus stacking software. I'm still learning this new technique but so far I'm doing OK. You can see the difference in the depth of field with the photos below, unstacked and stacked, of the eye in a peacock feather.
