As mentioned earlier, I find the RPP interface to be very non-intuitive and continued use has not changed my opinion. In addition to that factor the software has a few other quirks which, even thought one can work around them, are still somewhat annoying quirks. And, the software has not been updated since 2014 so its anyone's guess whether those issues will ever be addressed. Not to mention the fact that supported camera updates have come to a halt.
That written, with some Photoshop work on a file after RPP processing, the picture does have a pleasing film-like visual quality. However, I have found that, using the RPP + PS result as a guide, I can replicate the look using my standard RAW conversion software (Iridient Developer) - see the comparison pictures in today's entry. And, I can do so with a lot less time and effort than using the RPP program.
It is worth mentioning that I have always used my "de-digitalization" RAW conversion processing methodology with Iridient Developer. However, by messing around with RPP I have been able to further refine that "de-digitalization" processing technique. So, it was well worth the time spent using RPP even though it's going back on the shelf.
