Epson Raw File (.erf)

The ERF file extension, short for Epson Raw File, is a proprietary format used by Epson digital cameras to store uncompressed, raw image data. Developed by Epson, this format retains all original sensor data, allowing photographers to produce high-quality images with extensive post-processing flexibility. ERF files can be opened and edited using specialized software like Adobe Photoshop and Epson PhotoRAW. Despite their large size, ERF files are favored by professionals for their superior image quality and editing capabilities.

Sun Raster (.sun)

The Sun Raster (SUN) file extension, originating from Sun Microsystems, is a bitmap image format used primarily on SunOS systems. Known for its versatility in storing raster graphics, it supports various color depths, from monochrome to 24-bit true color. Initially created for the Sun workstation's image processing software, it facilitated efficient graphical data manipulation and transmission. Over time, its straightforward structure and compatibility with different Unix-based systems ensured its adoption in diverse graphic applications. Today, while largely historical, the SUN file format remains an important part of the legacy of early computer graphics development.
