Filterconcept: Search/Filtering/Current Visible Photos: Working with Base-filter plus Sub-filter

Image files have poperties (file-, exif-, xmp-, iptc- metadata) that "A Photo Manager" can Edit and that can be used to Search/Find/Filter Photos. This page describes the basics of filtering .

Both Gallery-View and Geographic-Map show only those photos of the device which are current visible.

Definition: Current visiblity = (Base-)Filter + xxx-Filter + Sort-Order .

The Filter (aka Basefilter) can combinde multible search/filter criteria ( menu "Filter" opens the Filter-View) .

Basefilter Example:

You can search photos about "peter" which are "taken in 2007". This translates to
- the text "peter" is contained in path, title, description, tags and
- photo-date is between 2007-01-01 and 2008-01-01

Additionally to basefilter a Photos can be filtered (or serached or found) by one of these

Searchbar : Any Text that is contained in eigther folder-path, filename, tags, title, description (the symbol opens the searchbar) New in version 0.7.0
Folder-Picker: Path (aka "filesystem folder" or "album" or Virtual Album) ( "" or menu "Folder Filter")
Geo-Picker: Geo Area ( or menu item "Map Area Filter")
Date-Picker: Date range when the photo was taken ( or menu "Date Filter") New in version 0.7.0
Tag-Picker: Tags ( or menu item "Tag Filter")

xxx is either path, date, geo, tags.

Only photos that match "xxx-Filter" are shown.

The Sorter determines the order in which the result photos are presented in the Gallery-View and in the Image-View. Pphotos can be sorted by

Name (folder path plus filename)
Date (with time when the photo was taken)
Place (geo or gps coordinate)
Rating (5=best .. 1=worst or 0/null unknown)
Last Modified (date and time when the jpg photo file was last modified i.e. modifying exif geo).
Width (of the photo in pixel)
Size (of the jpg photo file in bytes)
Sortorder
- ^ means assending (from smaller to bigger)
- v decending (from bigger to bigger)
