Camera Raw and DNG: DNG Convertor fails to convert Fujifilm X10 RAF raw files to DNG correctly.

Given a full size (4000x3000 pixel) input RAF file from the X10, the DNG output from DNG Convertor is always 2816x2116 pixels. Although I have seen the suggestion to set the DNG output as linear (http://www.lightroomforums.net/showth..., this does not help for Apple applications such as Aperture which cannot read DNG files containing linear output.

At present there seems to be no end-to-end workflow to handle X10 RAF raw files on OS X Lion - Fujifilm supplied software does not run on Lion (it's a PowerPC compiled application) and this problem with Adobe DNG Convertor seems to block the other obvious route of converting RAF to DNG before manipulating in another application.

Mac OS X 10.7.2
Adobe DNG Convertor 6.6.0.221

Just so that I understand ...

... after you convert the images to DNG, what software are you using to process those DNGs?

I'm pretty sure that DNG Converter 6.6 is writing the correct DNG. The full size RAF (HR mode for EXR) consists of 2 separate mosaic images, each 2816x2116 pixels in size. These are stored separately in the DNG (i.e., 2 mosaic planes). When reading such files, the raw converter is responsible for interpolating the two mosaic images to 4000x3000.

Thank you for the reply.

I usually use Aperture (version 2.1.4).

But I've also tried opening the DNG conversions with:
iPhoto 11
Preview
ContentaRawConverter
(all most up to date versions as of now)
None of these seems capable of interpolating correctly to the original size: it always comes out at 28xx by 21xx pixels.

Any progress on this? DNG converter still fails to convert X10 raw files at full resolution.
