I'm looking into converting my Canon RAW files (CR2) to lossy DNG purely due to storage limitations. I only shoot RAW and in my country storage (physical or cloud) can still be pretty expensive. I shoot a lot and I've about 4TB of RAW images. I have no space left.
I liked most of what I've heard about DNG, except the fact that changes that I make using Lightroom (my software of choice) go either into the catalog or into the DNG file. I really like the idea of having a separate file with metadata regarding my editing. If feels a lot more portable and safer, since if I want the "virgin" file I can just delete the XMP.
Is there a way to achieve the sidecar workflow with DNG?
