Focus stacking is a method of maximizing the depth of field of an image. Several images of an object are taken within a very short time, whereby the focus point is shifted slightly with each image. In this way, a new, very small area is precisely captured step by step for each image. These images are then stacked using the software, i.e. combined in such a way that only the sharp areas of each photo are integrated into the final image. The end result is a consistently sharp image with maximum detail.<\/span><\/p>\n

We offer two methods for this:<\/span><\/strong> firstly, changing the focal plane by moving the camera to a new position on the camera slider, whereby the secure fixing on the slider also prevents any shifts or distortions, and secondly by controlling the lens and the focus setting via a motorized focus. In both cases, the process can be precisely programmed using presetting in our scanning software. The result is a razor-sharp image of incredible detail, which can provide scientists with new information for analysis and comparisons and is a real eye-catcher for aficionados.<\/span><\/p>\n

However, focus stacking is not only the ideal solution for the digitization of herbaria but is also suitable for all collections whose objects have three-dimensional structures and whose details are to be examined more closely: whether insects, coins, pottery fragments, textile fragments, etc. \u2013 there are virtually no limits to the possible applications.<\/span><\/p>\n
