Next, identify how much of the image you would like to keep in focus. Occasionally, focus stacking is done with varying apertures to merge images with a different depth of field, but for simplicity’s sake, stick with manual mode and an even exposure until you’re more experienced with focus stacking. Then, go back to manual and use those same settings). (If you’re not yet comfortable in manual mode, turn the camera to programmed auto, and take note of those settings. If bringing a tripod isn’t possible, keep your composition as close as possible throughout the series.Ī focus stack is best shot in manual mode so that the exposure is uniform across all the images in the series. While software is now able to align the images automatically, with the auto align method, you lose resolution since you’ll need to crop off the edges that didn’t quite overlap. First, pick your scene and frame up your composition. To get that sharp final image, you need to shoot a series of photos with a different focal point in each one.

If you are shooting a landscape at night, focus stacking will create the look of a wider aperture, even though it wasn’t possible to use one.įocus stacking is also occasionally used in landscape photography, often when there’s an element in the foreground that, even with a large aperture, would still be out of focus. A wide aperture will let in a lot of light, but leaves most of the image out of focus. While macro photography is one of the biggest reasons to use the focus stacking technique, it’s not the only reason. By capturing the subject in a series of images instead, those details can be layered back in. While using a wider aperture can help, often, aperture alone isn’t enough to add that detail back in. Shooting up close to a subject, like in macro photography, creates a very narrow depth of field - so narrow, in fact, that a bumble bee’s antennae may be in focus, but his stinger is blurred into the background. Depending on the aperture settings and how close the camera is to the subject, the objects in the photo may be several feet apart and still in focus, or they may be millimeters apart and out-of-focus. So why focus stacking? Focus stacking tackles depth of field problems, or how much of the image is in focus. The result is an image that’s sharper than any of the original photos by themselves. A distant relative of high dynamic range, focus stacking layers images taken at multiple focus points instead of different exposures.
