I think you're missing my point. If I do processing in Adobe's format (DNG), then unless I want to re-process at some point in the future when Adobe decides not to support DNG, I'm once again at their whim.
Isn't DNG an Adobe product? Why would I put files in that format, when I have no idea what they're going to do with it in the future? They aren't winning a lot of friends with their business strategies.
The DNG format is an free and completely open format developed by Adobe, just like pdf's. Converting files to DNG does not destroy your original, you have several options, one, make a copy (this doesn't touch your original), or two, make a copy and include the original RAW file inside it (again, this doesn't touch your original).
Doing this via the free fully supported DNG convertor just means Adobe have given you the ability to use unsupported newer cameras in older software, entirely for free, without touching your original image file. Name me one other software company that does that.
There are good reasons to chastise the corporate way we seem to be racing towards, but I really don't believe Adobe deserve most of the hysteria and inaccurate hyperbole being thrown at them.
If I carry RAW and DNG in my computer, I have the above issue and eat up more of my hard drive as well.
I repeat my question, do you work for Adobe?
When did you first ask if I worked for Adobe? Don't bother, I don't, never have, never will.
I believe you are missing my point, and the capabilities Adobe have given you.
You say you have CS5 and a 6D and the RAW files will not open in your version of ACR? Here are a couple of workarounds that Adobe have left for us, but first, what format do you currently save your CS5 work in?
- Download DNG Convertor, convert a copy of your RAW file to DNG, open in CS5's ACR, process, open in CS5 process. Save as-------- This is where you are being obtuse, you always have to save your PS file as something, save it to whatever you save it now, TIFF, jpeg, PSD etc etc you don't need to save as a DNG, you just need to open it as one to work your new cameras files in your older software.
- Upgrade to CS6
- Pay $99 to get the CC version of ACR via Lightroom 5
So, one free option that doesn't touch your RAW file, one modest cost option that vastly increases your functionality that also doesn't touch your RAW file, CC/LR5's ACR is way better than CS5's ACR, and one marginal upgrade cost that gets your 6D files open but doesn't future proof you for long and doesn't get you the best available ACR, and oh, doesn't touch your RAW file.
The only difference to your current workflow is converting a copy of your RAW file to DNG to open it in CS5's ACR, it takes no more HDD space, it doesn't touch your original RAW file and your CS5 output file s identical to your current CS5 output files. Adobe provided and support that functionality entirely free. Again, give me one example of any other software company that provides a free fully supported program that means you can continue using old versions of their software with new hardware (new, expensive, cameras that's files are only unreadable because the camera manufacturers refuse to adopt any kind of RAW standard).
As has been said, DNG is an open format, it is far more likely that future third party software will be able to read DNG's than PSD's, or even some legacy RAW files.
For the record, whilst I have tested this to see if it works as I say (it does I have copies of CS4 and CS5 on older boot drive clones) I do not use DNG's as I have no need, I went the CS6 and LR5 route as, for me, that makes far and away the most sense.
