Sorry,
I think there are no pros for proprietary raw.
Photographers have right to their own pictures.
I don't think it is wise to thrust the photo industry to support their proprietary raw formats for archival periods of time.
What I would suggest:
- Photo industry adopts common raw format, it doesn't need to be DNG but DNG is mature and proven
- Adobe makes whatever is needed to support the photo industry with regard to DNG (I got the impression they do just that)
- Photographers would not buy equipment until it is supported by their raw package
I really think that those application that are not supporting DNG need to rethink:
- I wanted to try out DxO because I'm interested in their lens corrections. It doesn't work with undemosaiced DNG. One consumer lost, and I'm not alone.
- Wanted to try out Aperture, they won't support DNG one potential customer lost.
Best regards
Erik
Perhaps not just for DNG but personally it would help tip the balance of "pro" and "con".
I wish people could get equally passionate about viewfinders.
