An .sr2 file is a camera raw image captured by various Sony digital camera models, including the R-1. SR2 images are saved in the Sony RAW 2 (SR2) format, which stores uncompressed image data exactly how the camera's sensor captured it, allowing photographers to capture higher-quality images they can more accurately edit.

Since .sr2 files are uncompressed, they are typically large. Therefore, storing many SR2 images or sharing the images can be challenging. You can convert SR2 images to JPEG (.jpg) format to significantly reduce their size, although this will also result in some image degradation. If maintaining image quality is more important than minimizing file size, you can convert the images to the PNG (.png) or TIFF (.tif) formats, which use lossless compression instead of JPEG lossy compression.
