Mamiya Electronic Format (.mef)

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.

JPEG 2000 Code Stream Syntax (.j2k)

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
