A lens’s hyperfocal distance—a mathematical combination of lens focal length, aperture or f-stop, and focus distance—is a tool that photographers can use to maximize their depth of field for capturing nearby foregrounds and distant backgrounds in acceptable sharpness.
While you can always dial up your lens’s sharpest aperture (sweet spot), many landscape photographers want as
Knowing your lens’s sharpest aperture—its “sweet spot”—is one surefire way to maximize image sharpness. Image sharpness is the goal of many photographers—regardless of the subject matter. Sharpness is also the catalyst for the dozens of lens-testing and review websites that populate the Internet, as well as the impetus for endless snobbery and debates over which lenses reign supreme in the quest for ultimate clarity. In my article,
There are few genres of photography as technical as macro photography, and it seems like the closer to a subject you get, the trickier it can be to work out all of the variables of exposure, focus, and sharpness. While figures like magnification, aperture, and depth of field are still relevant in all arenas of photography, they take on a new level of importance when working close up. The reward to solving a puzzle like this, though, is dynamic

Join Kelly Mena, of B&H Photo, as she explains the basic principles of depth of field in photography. Mena defines depth of field and explains the distinction between its deep and shallow variations—the former rendering everything from subject to background in sharp focus, the latter rendering the subject in sharp focus and the background soft and out of focus. Mena discusses the variables you can use to control depth of field in your images: aperture, focal length, and camera-to-subject distance. She also explains how you can use the ISO
