PEF to JPG: what carries over and what does not

PEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to JPG bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. PEF carries 14 bits per channel and JPG carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end.

PEF to JPG 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 JPG files?

JPG is one of the most popular image file formats currently in use, often referred to as a standard for uploading images online and for displaying photographs. One of its main advantages is providing a good image quality in a relatively small file size, which is easy to store and transfer. JPG uses a type of compression that prioritizes the quality of some image sections over others, thus assuring that most favorable quality/size ratio.
