SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
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.
