Hi All,

As I now take the majority of my images using the RAW setting on my 400D after reading various threads on the benefits of using RAW, I now read that there are concerns with the RAW file format because there's not a single, universal format for RAW images.

So, would it better to save the RAW file in Adobe's DNG format for archival reasons (as I believe the DNG format is expected to be adopted by all the major camera manufacturers in the near future and catered for by Adobe)? Do many people do this and if so, do you then delete the RAW file and just keep the DNG file? I understand the original RAW file can be embedded into the DNG file but this would increase the file size further, but saving the DNG file only will allow it to be compressed (which, apparently, is lossless) reducing the DNG file size.

I can't see any issues in saving the DNG files and deleting the RAW files but I may wrong, hence my post

I would be interested in others opinions on this.
