Description
The X3F file format, also known as the SIGMA X3F Camera RAW File, is a proprietary image format developed by Sigma Corporation for storing raw image data captured by Sigma cameras equipped with the Foveon X3 sensor. Unlike standard JPEGs or TIFFs, X3F files contain unprocessed data from the camera's sensor, offering photographers greater flexibility in image editing.
The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
