If you believe that the issue is not acute then you blithely disregarding obvious facts.
Andrew Rodney himself told you how he lost RAW images from first-generation digital cameras.
Hi Tony,
I'm not sure if/where Andrew, in another thread maybe, said that he lost Raw images.
Assuming he can read/copy the Raw files from disk, converting them to another format doesn't solve an issue.
Access to the code to interpret
all the file data may be an issue when the original manufacturer ceases to exist, but there are plenty openly available solutions (DCRaw, RawTherapee, etc.), and a number of commercial ones, to decode the image data to a degree that an excellent image can be produced (sometimes with even better quality than the original solution). Without access to all of the original proprietary data (by means of an SDK, or with the source code), converting to another file format doesn't solve an issue.
To give you an idea, DCRaw apparently can convert (amongst others) the following Kodak Camera Raws (don't know which one Andrew Rodney is referring to):
•Kodak DCS200
•Kodak DCS315C
•Kodak DCS330C
•Kodak DCS420
•Kodak DCS460
•Kodak DCS460A
•Kodak DCS520C
•Kodak DCS560C
•Kodak DCS620C
•Kodak DCS620X
•Kodak DCS660C
•Kodak DCS660M
•Kodak DCS720X
•Kodak DCS760C
•Kodak DCS760M
•Kodak EOSDCS1
•Kodak EOSDCS3B
•Kodak NC2000F
•Kodak ProBack
•Kodak PB645C
•Kodak PB645H
•Kodak PB645M
•Kodak DCS Pro 14n
•Kodak DCS Pro 14nx
•Kodak DCS Pro SLR/c
•Kodak DCS Pro SLR/n
I have no idea what the proprietary data in those Raw files could add to the conversion quality, but I do know that the demosaicing quality has improved a lot since those cameras were current, so maybe todays conversion quality trumps the old, even without the missing info. I'm glad that we didn't convert the original Raws into something that is an interpretation/abstraction of the original data, and afterwards came to realize that we didn't convert it as good as we can today. Still, it would be nice to also understand the unknown bits.
You believe that your RAW images are safe - for how long: five years, ten, fifty years?
I don't think it's an issue about being safe. Safe from what? It can't be floods or Global warming, because converting to another format would not make any difference in that respect.
The only potential issue from a user perspective seems to be the interpretation of some of the proprietary bits, the non-imaging sensel data, and the undisclosed maker notes in the EXIF metadata (as far as they are related to image-data decoding). Again, without access to an SDK or original source code that utilizes that data, converting to another file format doesn't change anything for the better.
We also should realize that much (most?) of the turmoil is caused by companies like Adobe who, for commercial reasons, force people to update the image editing software, because newer camera models are deliberately locked out. It is therefore no surprise that Adobe also offers a 'DNG solution' (for an issue they partially create themselves), which would benefit them by not having to interpret multiple Raw formats.
Frankly, I'm increasingly amazed by the high conversion quality that programs like RawTherapee can produce, even without intimate knowledge of the unknown bits ..., and some of the issues I see with the ACR/LR Raw conversion quality. It would seem wiser if they spent more resources on that conversion quality before others (also lacking the proprietary info) take too much of a lead.
Cheers,
Bart
