Fidelity When Converting ARW to PSB

Quality in this conversion depends primarily on your source file. A high-quality Sony RAW input produces an excellent Photoshop Big output. Since the target format is lossless, output quality matches your input exactly. Sony RAW encodes data using mathematical algorithms that preserve every data point. Photoshop Big prioritizes exact data preservation. The conversion maps between these approaches intelligently. Sony RAW's known limitation — requires Sony Imaging Edge or compatible RAW editor — is resolved when converting to Photoshop Big, which offers supports files up to 300,000 x 300,000 pixels and over 2GB.

Converting between image formats is one of the most common file operations. When moving from Sony RAW to Photoshop Big, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
