Let’s not get sidetracked here, but it is worth mentioning that microscopes work with lenses, so depth of field is still a major factor. It’s especially important to have accurate focus in product photography, so focus stacking can help you get every aspect of a product in focus, even if you’re having to compromise on your aperture setting. You may find it easiest to use your body to move forward, rather than your focus ring, to get snaps of every point of focus you want for a macro focus stack. It’s painfully easy to lose your point of focus, especially with a moving target (think insects). Macro photography combines two things that don’t really go together: an extremely shallow depth of field and the need for absolute stillness. So, it may be better to get several shots at an aperture of, say, f/5.8, then focus stack them. You would think the aperture setting that provides the widest depth of field would just make sense, right? Except a “perfect” focus at an aperture of f/22, for example, could result in lens diffraction that softens that focus. In a landscape situation, you’re often trying to cover a lot of ground with one aperture setting. You don’t need an excuse to use focus stacking, but there are a lot of situations where it certainly makes sense. When you know your lens’s sweet spot, you can focus stack multiple images of that super-sharp focus level at different points in the composition and harness it throughout the final photo. For most lenses, this means 2-3 stops from wide open. This is why it’s important to know your lens’s “sweet spot” – the setting that results in its sharpest possible point of focus. A narrow aperture creates a wide depth of field, but can result in diffraction, which causes a soft focus.A wide aperture creates a shallow depth of field, meaning you may have trouble keeping everything that’s important in your image focused at once.Both a wide-open aperture and a tiny one can create focus issues in their own way: Your aperture setting will be one of the most important factors as you shoot to focus stack. Fortunately, the editing part is nearly as simple as shooting, and we’ll walk you through it step by step a little later on.ĭepth of Field and Your Lens’s “Sweet Spot” It’s a half-shooting, half-editing process, since you have to actually combine all those different points of focus in post-processing.

By taking multiple shots of the same scene at different focus points, you’re covering all your bases for the final image. To create an HDR image, you take different levels of exposure for the same scene, then take the best of the highlights, shadows, and midtones out of all those exposures to create one, superbly-balanced photo.įocus stacking is the same idea, if you switch exposure with focus. To understand focus stacking, it’s easiest to make a quick comparison to HDR, since it’s a process most photographers have a baseline knowledge of.
