The RAW Problem
Wednesday, May 31st, 2006OpenRaw.org, an organization dedicated to pushing camera manufacturers to publicly document their RAW image formats, has released its 2006 survey of photographers and imaging professionals.
Albeit long, it’s an interesting document that showcases the concerns of people in the industry about ever-changing, manufacturer-proprietary RAW formats and its potential pitfalls.
More than two-thirds of the 19,207 participants expressed concern that they won’t be able to open or edit raw files created by older digital cameras. The most telling statistic is the 90% of respondents who agreed: ‘Once a digital image is written to a file by a camera, data in all parts of the image file should belong to the photographer who captured the image. Camera makers should publish full and open descriptions of all parts of the raw image files their camera produce.’
What *is* the RAW problem, exactly?
From OpenRAW.org: In the short history of digital photography, manufacturers have released numerous cameras with constantly evolving RAW formats. This has lead to the existence of a vast number of RAW “dialects,” even within each major brand, that store image and camera setting data in a different manner.
In some cases, manufacturers have even encrypted the data within newer RAW files. Intentionally or not, this encryption has placed full access to the images stored in these files out of reach of the photographers that took them. Unless, of course, they limit themselves to tools sold by the camera manufacturer.
To date, this vast number of RAW formats has been hidden by the transparent support offered in RAW converter software, provided by both the camera manufacturer and various third parties. At the time of writing, the open source dcraw converter currently supports more than 200 formats. However, as manufacturers lose interest in their discontinued products and drop support for them, the true impact of all of these “dialects” will be felt.
Photographers will find their older images inaccessible, as future software versions lose support for older cameras. In the worst cases, entire brands may disappear, as has already happened with Contax.
The OpenRAW Solution: The goal of OpenRAW is to encourage image preservation and give creative choice of how images are processed to the creators of the images. To this end, we advocate open documentation of information about the how the raw data is stored and the camera settings selected by the photographer.
