Pentax Raw Image File
PEF (Pentax Electronic File) is a raw image file format used by Pentax digital cameras. These files contain unprocessed data from the camera's image sensor, allowing for greater flexibility and control during post-processing. The format is similar to other raw formats such as CR2 (Canon) and NEF (Nikon).
PEF files offer several advantages over JPEGs and other processed image formats. For one, they retain more image information and can produce higher quality images with less noise. They also allow for greater control over things like white balance, exposure, and color.
