Convert MEF to JBG

The Mamiya Electronic Format (MEF) is a raw image file format used by Mamiya digital cameras to store unprocessed and uncompressed image data directly from the camera sensor. Introduced in the mid-2000s, MEF files maintain the original scene's dynamic range and quality, allowing professional photographers extensive post-processing control. These files are typically large due to their uncompressed nature and include vital metadata such as exposure settings and white balance. MEF files are commonly edited using specialized software like Adobe Photoshop and Lightroom.

The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
