There are many obstacles for outdoor photographers to overcome when shooting in the field. For example, you think you have a tack-sharp photo when you look at the image on your camera, but when you look at the photo on the computer screen you realize that it’s slightly out of focus. One of the ways you can fix focus issues is using a smaller aperture such as an f/16. However, even a small aperture can reveal some fuzzy focusing. In order to be sure you have tack sharp focus throughout a deep field of focus, you need to use a technique called focus stacking. In this tutorial, I’ll show you how to focus stack in the field for the sharpest photos ever.
