Technical note

What changes when you convert PEF to STP

PEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to STP 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 is made of pixels and STP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STP container.

FAQ

PEF to STP Conversion

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 STP files?

STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.
