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.

Over The Air Bitmap Image (.otb)

The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
