What is an ARW file?

The ARW (Sony Alpha Raw) format is a proprietary raw image container generated by Sony Alpha, Cyber-shot, and NEX series digital cameras. It adheres to the TIFF (Tag Image File Format) specification, storing unprocessed photodiode data from the image sensor in either uncompressed, lossless compressed, or lossy compressed (11-bit + 7-bit delta) variations. The file encapsulates extensive EXIF metadata, maker notes, and a JPEG preview, requiring specific demosaicing algorithms to interpret the Bayer pattern data for display.

How to open an ARW file

Opening ARW files requires software capable of decoding Sony's proprietary Bayer interpretation. Sony provides the free Imaging Edge Desktop software for native handling. Industry-standard post-production tools such as Adobe Lightroom, Capture One, and DxO PhotoLab offer full support. On Windows, the Microsoft Raw Image Extension allows native viewing in the Photos app, while macOS Preview supports most ARW iterations natively via Apple's Core Image RAW engine.

What is a PSD file?

The Photoshop Document (PSD) is the proprietary file format of Adobe Photoshop, capable of storing an image with support for all available imaging options including layers, adjustment layers, layer masks, alpha channels, paths, and vector text. It utilizes Run-Length Encoding (RLE) for compression and allows for a maximum file size of 2 GB and dimensions up to 30,000 pixels. The format maintains the editing history and non-destructive elements of a project, unlike flattened raster formats. The internal structure is divided into five parts: File Header, Color Mode Data, Image Resources, Layer and Mask Information, and Image Data.

How to open a PSD file

Adobe Photoshop is the primary software for full PSD support. However, several other programs offer varying degrees of compatibility. GIMP (GNU Image Manipulation Program) and Paint.NET (with a plugin) can open PSD files but may not render complex layer styles or adjustment layers correctly. CorelDRAW and Affinity Photo also provide robust support. For simple viewing without editing, standard image viewers like XnView or IrfanView can often display the flattened composite preview embedded within the file.
