MEF images: Frequently Asked Questions
What are MEF files?
MEF (Mamiya Electronic Format) is a raw photo format used by Mamiya and Phase One digital cameras. It is similar to other raw formats like CR2 (Canon) and NEF (Nikon), but is specific to these particular camera brands. MEF files contain all of the raw image data captured by the camera's sensor, as well as metadata and other information about the image. This allows for greater control and flexibility in post-processing, but also requires specialized software to work with.
