Also, looking at what's available for RA4 (paper especially), I'm starting to have doubts about the process's future.
I wouldn't worry about possible discontinuation of RA4 paper in the near future. Don't forget that a lot of digital images get printed to RA4 paper via light jet, since it still seems to be cheaper and/or more durable than color inkjet prints. Obviously a lot less is printed today than ten years ago, since most digi snappers are content with looking at their photos on the LCD screen of their cameras. But still: the availability of RA4 paper does not only depend on the few remaining color film shooters, so it should be around for a while.
Trying to be the best of whatever I am, even if what I am is no good.
