What is a .bay file?

The .bay file extension is primarily associated with RAW image files generated by Bay Photo Lab. These files capture unprocessed data directly from a camera sensor, offering maximum flexibility for post-processing. Unlike standard image formats like JPEG, RAW files retain a wider range of color information and detail, making them ideal for professional photography where precise editing is crucial. Storing uncompressed or minimally compressed sensor data, .bay files are larger than JPEGs but provide superior quality for retouching and printing.
