What is a .pef file?

The PEF file extension represents a raw image format used by Pentax digital cameras. Raw image formats, like PEF, store the unprocessed data captured by the camera's sensor. This means the file contains all the information recorded during the exposure, without any in-camera processing such as white balance adjustments, sharpening, or noise reduction. This allows photographers to have maximum control over the final image during post-processing. PEF files are similar to other camera raw formats like NEF (Nikon), CR2 (Canon), and ARW (Sony). Because they are unprocessed, PEF files are typically larger than JPEG images. They offer greater flexibility for editing and can preserve more detail, especially in highlights and shadows. Editing PEF files requires specialized software that can interpret the raw data and apply the desired adjustments. The advantage of using PEF is the ability to make non-destructive edits, meaning the original raw data remains untouched, and changes are saved as metadata. This allows for experimentation and the ability to revert to the original image at any time.
