Questions & Answers
PTX images: Frequently Asked Questions
What are PTX files?
PTX is a raw photo format used by Pentax digital cameras. It is similar to other raw formats such as DNG and NEF, in that it contains all the unprocessed data captured by the camera's image sensor. This includes information about each individual pixel's color and brightness, as well as other metadata collected at the time of capture. PTX raw files are typically much larger than compressed JPEG images, but they offer much more flexibility for post-processing and image manipulation.
