PEF to GBR Conversion: FAQ

What are PEF files?

The PEF image format is used for creating RAW images with Pentax cameras. Shooting in RAW mode allows the camera to capture everything its sensors can register, thus preserving a huge amount of details — as opposed to JPEG or other compressed formats, which have predefined settings and are processed automatically. With PEF images, photographers have more freedom to change the image during digital post-processing without affecting its quality. With the help of specialized software, aspects such as lights, exposure and shadows can be customized in the image, highlighting or hiding particular details.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
