With such a wealth of brilliant images on Picfair, we wanted to create categories that would gather images of our most popular topics together. Like search, categories are created using an algorithmic formula that searches our library for images on a given topic that are both relevant and beautiful.
The formula that we use to create the categories is constantly being refined, but like search, it is a half-human, half-machine algorithm that looks for relevant titles, captions and tags, and indications of quality like stars and views.
Categories are intended merely as inspiration or somewhere for people to browse rather than where they would make a targeted search for a particular type of photography. Our search function has extensive filters that are intended to allow buyers to drill down into the results to target the image they need - you can access this here.
