Sift.pics

Historic photographs in public collections very often lack basic classificatory tags – whether a picture is an interior or exterior view, has the picture been taken from ground level or from a raised viewpoint (a higher floor window or tower), is it a view photograph depicting mainly a place or a reportage photo about an event etc. Most of these decisions are easy to make for everyone only by looking at a picture, so it is useful to capture that information that would enable bulk filtering of images afterwords.

Sift.pics is a participatory crowdsourcing application for that kind of binary categorisation about images. We take in pictures from public collections and ask you to browse the images and make couple of sorting decisions, you can favorite (bookmark) images, see the title of the image and open the image in an official web repository.
