He's wrong about this and always has been - not least, I imagine, because I've noticed that for some reason the Bibble/ASP demosaicing algorithm definitely tends to suit his Nikon files, and he has little or no hands-on experience of the issues that users of other cameras see. (In fact the two users who I know
to be Bibble/ASP beta testers are both Nikon shooters, which might explain a lot).
I don't use any
in-Bibble or in-ASP sharpening, and I know bad demosaicing when I see it. I've used Raw Therapee as an educational test-bed for a good few years now, primarily because
of its many demosaicing options: I've spent probably hundreds
of hours testing demosaicing algorithms in RT and in other software, and I know that good demosaicing looks like and
how to recognise poor demosaicing.
Sure, the sharpening in ASP is poor, and that makes the problems inherent in the demosaicing worse; but - as Frank also observes above - they're there anyway
. Like Frank I've been using Bibble for years - since 2006 for me - and we know what we're talking about, despite the frenzied denial from some quarters.
better than Bibble, primarily because at long last Noise Ninja is working properly - and maybe
because of colour management improvements (dark-light transitions seem a bit smoother) - but there's a long way to go yet, and in fact I understand that the devs are now finally looking into this seriously.
But for clarity, waaaay
back in Bibble 4 days - as long ago as 2007
, in fact - one of the devs (Colleen) posted on the old forum
that they were actively looking at introducing new demosaicing algorithms because
of recognised shortfalls in the one in use in Bibble; and nearly five years later we're still waiting for a solution to what was acknowledged all those years ago to be a real, observable and addressable issue
, and the exact same problems identified in that thread (and other demosaicing-related issues) are being seen in ASP.
