Category:Images by technical criteria

 See also category: Technical examples.

This meta category should only contain other categories. Files should either be in the relevant subcategory or in the parent category.

This category organizes images by technical criteria. A technical criterion is anything that can, at least in principle, be automatically determined. Examples are, dimensions, number and resolution of color/alpha channels, file type, existence of metadata, histogram properties (like monochromatic 24bit JPEGs), images with high or low contrast (as defnied in a technical sense), and so on. Ideally, this category and its subcategories will be automatically maintained.
