fokusstabling

Fokusstabling is a photographic technique used to increase the apparent depth of field in an image. The method involves taking several exposures of the same subject at progressively different focus distances. These individual images are then combined using image‑processing software to produce a single composite photograph in which more of the scene appears sharp. The word originates from the German "Fokusstapelung," meaning “focus stacking,” and is translated into Norwegian as "Fokusstabling."

The fundamental idea behind fokusstabling is that different parts of a subject will be in sharp focus at different distances from the camera. By blending the best‑focused portions of each shot, the resulting composite can exhibit a depth of field that exceeds the limits of any single exposure. The technique is particularly useful in macro photography, product photography, and any situation where an unusually large depth of field is desired, such as under low‑light conditions or when using wide apertures.

Typical workflow for fokusstabling begins with careful planning: setting the camera on a tripod, selecting a stable shooting point, and ensuring minimal subject movement. After shooting the series, post‑processing software such as Adobe Photoshop, Helicon Focus, or the open‑source GIMP can align the images and merge them. The software uses edge‑detection algorithms to determine the sharpest pixels from each source photo.

While fokusstabling can yield remarkable results, it has limitations. It requires stable equipment and static subjects; otherwise motion artifacts can degrade image quality. Additionally, the process can be time‑consuming both in shooting and processing.

Fokusstabling remains a standard practice in high‑end photography where the best possible detail and depth is essential.
