MOS to CAL Conversion: FAQ

What are MOS files?

The MOS image format is associated with shooting in RAW mode using Leaf cameras. Leaf is a brand of high-end cameras of medium and large format, and after being a division of Scitex and Kodak, it is now a part of the Danish group Phase One. MOS images are RAW images taken with the Leaf Aptus series, but they can also be associated with Mamiya cameras. They represent uncompressed images which include a significantly wider array of details than other compressed formats, such as JPEG.

What are CAL files?
