MEF to J2K

Upload a MEF camera RAW file and save it as J2K. The converter uses server-side image processing for quick RAW export to common raster formats.

MEF is Mamiya's own RAW format. A high-quality Japanese brand is well known to those who take professional photographs. His story began in the 1940s. It was then that camera designer Seiichi Mamiya and investor Tsunejiro Sugawara created Mamiya. Mamiya ZD cameras are the first mid-format digital cameras. The expanded name of the MEF format is Mamiya RAW Image. He gained fame as a format of "digital negatives". Mamiya has developed this format in order to use it in cameras of its own production. At the same time, the main goal was to store the photos in an uncompressed form, so that later they would be processed without losing quality. The format is built on the principle of a RAW file. It contains a complete set of information that is received from the camera lens. RAW images are uncompressed files. They can be customized using image editing software. They are often preferred by professional photographers, because they are tasked with having high-quality images with many details. An MEF file is capable of storing an image as if it had been made into a CCD camera device. In most cases, it is stored on a memory card, and then transferred to a computer in order to edit and publish.

J2K is a raster image category file format. It is a compressed bitmap using wave compression instead of DCT compression, which is used by standard .JPEG images. The format supports 16-bit color, alpha transparency and lossless compression. The file type is JPEG 2000 Image. The J2K file format was developed by the Joint Photographic Experts Group (JPEG). J2K is an update to the JPEG format that includes original features. Say alpha channel support and lossless compression. J2K is a segment of a large package of updated JPEG extensions. They gained fame as JPEG2000. Such as J2C, JPX, JPM or JP2. The lion's share of such formats are combined with the main programs so that you can view images. However, JPEG is particularly popular. For those who specialize in photography, it is important that they have the opportunity to reduce the file size, while saving it on disk with the same frame size and at the same high visual quality. How to get out of this situation? You can, for example, store images in JPEG2000 format with the file extension jp2 or j2k. The compression algorithm and the format itself have been known for over 10 years. Nevertheless, there is no need to talk about its widespread use. That's because his "big brother" JPEG is firmly holding on to its position.
