RAW photo format designed for Sigma cameras. It uses Foveon technology that extends the sensor's range of sensitivity, allowing you to record the maximum amount of information with each shot. It allows you to make subtle adjustments to the white balance, color, exposure, and other settings while preserving all of the details in the photo.

This format is a vector images file in the Sketch Drawing program, which serves to edit and create interface designs, applications and software shells. SK-files contain objects and layers which can be edited independently of each other.
