Well, Strabo actually has a good point there...I might just start converting my CR2's to .DNG!
Just now, I record RAW or Raw + Fine JPG, and import using Adobe Lightroom 1.2, then any adjustments that are above and beyond Lightroom I do in Adobe Photoshop CS2 - don't use CS3 yet.
As I've said before, a standard needs to be reached in terms of RAW imaging, but the one thing I will say - OPEN SOURCE - That is a must, no one company should have the control or right to it as then, like sony has done for years on cd's and dvd's, hold the rights, then sell them for those who want to use the CD/DVD "Brand" and physical properties.
.OSR would be a good extention for such a system
The problem is with ever advancing ways of storing and calculating the RAW data, and making sure that they are compatible with older imaging software.
I don't see why ever camera (DSLR anyway) doesn't offer the option of recording a TRUE raw image, as in, EVERYTHING the sensor takes in, no compression - and just make it the one format, then any advancements made in lossless compression doesn't need to be used.
