The RAW Problem
Most camera manufacturers use a proprietary file format to store the raw data from their digital cameras. In the short history of digital photography, manufacturers have dropped support for asset management applications, abandoned settings from older RAW processor versions and changed the methods of storing basic camera settings without documentation.

What is RAW and Why it is Important
A RAW file is a proprietary file format created by a manufacturer to contain the raw data from a digital camera.

The Problem with Proprietary RAW files
Closed, proprietary, RAW file formats present many immediate and future challenges for photographers and anyone who uses digital images.

The OpenRAW Solution
We want camera manufacturers to publicly document their RAW image formats — past, present, and future.
