Overview

What is an MRW file? An MRW file is a raw photo created by a Minolta Dimage digital camera. It contains uncompressed, unprocessed image data saved exactly as it was captured by a camera's CCD sensor. Because MRW files contain a large amount of data, they have quite large file sizes.

More Information MRW file open in Adobe Photoshop Many professional-grade digital cameras save photos as camera raw files. These files contain all the data captured when a photographer took a picture. Retaining this data in its raw form allows photographers to edit elements of the image, such as its color temperature and exposure, more precisely than they'd be able to if the data was processed or compressed. Minolta Dimage cameras, such as the Dimage 7 and Dimage Z2, save camera raw images as MRW files. When Sony acquired Minolta, they phased out the MRW format and replaced it with the .ARW format.
