Now there is also Bibble available for the ZD. http://www.bibblelabs.com/
I tried the demo but wasn't very satisfied with the results. Even though I like the idea of having Noise Ninja and Ptlens integrated and being able to use custom profiles. I can't understand why Silkypix don't accept custom profiles.
Silkypix is always improving so it might happen.
Incidentally, is there any way to change the scratch disk for Silkyoix to another drive? My system drive is pretty full but I have a shedload of space elsewhere.
No doubt in my mind that Silkypix does the best job with ZD files except for some instances when the colour balance is a bit off.
