About the Photos

Contributing photographers can choose among a number of different licensing options. A default license, selected by the photographer, is associated with each photographer account. Photographers can apply this license to all of their photos, or they can change individual photos to have a license different from their photographer default.

CalPhotos licenses apply to the larger image file (around 800 pixels wide) that is in CalPhotos but not to high resolution versions of the images which CalPhotos does not store, and not to the smaller thumbnail images. Photographers can use any license they wish for their high resolution images; the license does not have to be the same as the license used by the CalPhotos versions of their images.

Thumbnail images (128x192 pixels) may be freely used for personal or academic purposes without prior permission under the Fair Use provisions of US copyright law as long as the photo is clearly credited.

Below is the list of possible CalPhotos licenses.
