Why searching for photos is so difficult.
By default, photos do not contain any information about the content displayed on a photo. For example, a photo does not “know” that it has a playground with a climbing frame and a slide. The photo simply does not contain this information.
Take a text document for comparison. This document contains all information to describe the content textually.
The text document contains everything needed to find this document based on the content. We have no problem locating the document while searching for climbing frame, slide or even playground.
Different with our photo; there is no way to find it based on the content.
The photo does not contain this information and therefore we can not search for it. Only if the photo “knows” what it contains, we can find it too.
So we have to teach the photo that it “knows” what it represents.
To do this, we need to add additional textual information to the photo; Text information describing the content of the photo.
We can then use this information, for example, to search the photo like a conventional text document.
Some common file types support this storage of additional text information. In common usage, this information is called metadata. They contain extensive information that can be saved in addition to the pure image in a file.
For example, metadata may contain information such as the time of recording, information about the camera being used, but may also include information about the content of the photo.
For example, the metadata for describing a photo can be edited directly in Windows for JPG files. However, the effort of manually editing large photo collections is immense. TagYour.Photos offers you the possibility to automate this content description. Thus, your photo collections are searchable without any additional effort for any terms or even for people.
