ARW is a raw image file format used by Sony digital cameras. It stores unprocessed data from the camera’s sensor, offering the highest level of detail and flexibility during post-processing. ARW files are typically large but retain every detail of the original shot, allowing for precise adjustments in editing software.
BMP is a bitmap image format primarily used on Windows-based systems. It stores images as pixel data and offers high-quality output without compression. While it provides precise details, BMP files tend to be larger than other formats like PNG or JPEG. It’s less commonly used for web applications due to its large file sizes.
