RawExtractor is a program to convert quickly RAW files to JPG. If you use RawExtractor, you can watch immediately RAW photo images after shot. Because RawExtractor extracts the data stored for previewing and converts to JPG, it produces more than 2 JPG images per one second. In addition, because it adds and stores rotation information and various shooting information in EXIF header of JPG, you can watch a photo and inquire shooting information with only JPG. RawExtractor can specify options such as conversion method selection, specification of converted photo storing location and addition of postfix onto the name of file.
