> > Just curious -- are PEF and TIFF file formats open source? TIFF is a published, documented format, and there is an open source library that supports the standard version. The same is true of JPEG.
EXIF is an extension to TIFF (or to JPEG), and is a way to include all sorts of additional data which (amongst other things) documents all the settings on the camera, etc. a PEF file really is just a TIFF file, including EXIF data, low-resolution JPEG thumbnails, etc. But the image data is the raw sensor data, not anything you could view directly.
