These are applications that allow you to view and manage digital images in different formats. They are specially designed for quick visualization of images, but also offer interesting functionalities in intake, metadata processing, basic processing and output. There is such a wide range of options that it is sometimes difficult to choose a single or main solution. However, these are not restrictive applications so, for instance, it is possible to use one program for importing, another for embedding metadata in batches and another for selecting images according to the appraisal policies established by the institution.
