I’ve only used ACR for a short time, but I was wondering what the advantages were of converting my .CR2 format files (the current Canon camera raw format) over to the Adobe DNG format. I can import CR2 files into Lightroom 1.1 and adjust them without conversion to DNG, and I can do the same in Photoshop CS3.

Why should I convert the files to Adobe’s format?

Thanks.

Have you checked this out yet:

For additional information and guidance, refer to chapters 3 and 7 of Bruce Fraser’s excellent book, Real World Camera Raw.

Both good sources.

I personally do it be cause they are much faster to work with and store all metadata properly on top of all the other reasons given. Besides that i use the DNG converter to do my batch renaming (adding date and description) while processing the pics.

Thank you Larry and Brett for your answers. One reason I found helpful with DNG is that the metadata reflecting changes to a DNG file is kept in the DNG file, while any changes made to a CR2 file is kept is a separate file. If you lose the separate file, you lose all the changes you have saved.

Thanks again guys for helping out a newcomer.
