Sigma Camera RAW Picture File
X3F is a raw image file format used by Sigma cameras, specifically those with Foveon X3 sensors. The format captures all the data from the sensor without any in-camera processing, allowing photographers to have maximum control over post-processing. The Foveon sensor is unique in that it captures full color information for each pixel by layering photodiodes, distinguishing it from other camera sensors.
Canon Digital Camera Raw Image Format
CRW was one of the early raw image file formats used by Canon digital cameras. It captures all the data from the camera’s sensor without any compression or processing, preserving the maximum amount of image information for post-processing. However, this format has largely been superseded by the newer CR2 and CR3 formats, which provide more advanced features and better compression. CRW files require specialized software for viewing and editing, and they are generally larger in size compared to standard compressed image formats.
