With the help of the duplicate finder it is possible to find photos that are duplicate or multiple in the archive and mark them for deletion if desired.
For all dialog elements there are tooltips that appear as soon as you move the mouse pointer over the corresponding element. This is important because they often contain important explanations.
We distinguish three types of duplicates in the Duplicate Finder:
a) Exact duplicates: These are photos or files that are binary identical. Since this requires checking each file again, this duplicate search takes longer. It also requires access to the original files. This means that external hard drives must be connected in order to find exact duplicates on them.
b) Near duplicates: These are photos that are visually similar. The degree of similarity can be adjusted by a slider. The stricter the setting, the more you will find almost exact duplicates. Here you can optionally choose between a faster or a more accurate search algorithm.
Variant b) is therefore our standard recommendation for duplicate search.
c) Sequences or bursts: These are photos of a sequence whose shooting date may differ only by a certain duration, which can be set. This function is also useful when photos differ because they have been edited or developed differently. Since the capture date is identical for these photos, you can thus find different variants of a photo (different white balance than the raw, B/W, etc.).
