The SFW file extension, created by Seattle FilmWorks, was used to store digital copies of photos processed by the company, allowing customers to receive both physical prints and digital images. Although not widely supported by modern software, SFW files can still be opened and converted using tools and older versions of image viewers. This format marks a significant step in the evolution of digital photography.
The HRZ file extension is integral to Slow Scan Television (SSTV), a digital imaging technique used in amateur radio to transmit images via radio waves. The HRZ format efficiently stores images in a 256 x 240 RGB bitmap, making it ideal for low-bandwidth transmissions. SSTV encodes images into audio signals, which are then decoded back into visual files, producing an HRZ file. This technology is crucial for image communication in bandwidth-constrained environments.
