I didn't say PSD will not being supported, I was talking about RAW files.
Every camera manufacturer has there own proprietary RAW format.
A single brand will have a dozens of different RAW file types over the years.
Some of those old Raw type may not be supported in the future, that is you may not be able to find new software that will work with those files.
That's the purpose of DNG.
Convert you're RAW files to DNG and Adobe says they will always support it.
The biggest benefit in shooting RAW is the ability to use the powerful tools in ACR and it's all non-destructive.
If you're finding it annoying you're telling me you don't understand the power of ACR.
As for your last comment:
You can't convert a PSD an image file, to a DNG a data file.
If you want to share the image with friends save it as a JPG
PSD, JPG, TIFF, and many others are "Image file types" and they all have different positives and negatives.
DNG, ARW, CR2, along with dozens and dozens of other file types are "Data files types".
The RAW file is a collection of the data gathered when you took the picture, but it's not yet processed as an image with all the settings locked into the image.
With a raw file you can adjust exposure, change white balance, adjust for clipping and much, much, more and it's all non destructive.
I'll look for more information, maybe a video tutorial.
If I find something useful I'll post it here and if you have more questions please ask,
