osera Posted August 28, 2006 Share #1 Posted August 28, 2006 Advertisement (gone after registration) Sorry if I missed this- Is there any info on whether the M8 dng files will be identical to the DMR? That is, will the current raw processors (ACR, C1, others) need an update to process M8 files? Link to post Share on other sites More sharing options...
Advertisement Posted August 28, 2006 Posted August 28, 2006 Hi osera, Take a look here M8 raw files. I'm sure you'll find what you were looking for!
Guest guy_mancuso Posted August 28, 2006 Share #2 Posted August 28, 2006 Great question Allen, I would say no right off the top. Since there is a new firmware and software company besides Imacon , I am assuming not but certainly hope I am wrong. Link to post Share on other sites More sharing options...
adan Posted August 28, 2006 Share #3 Posted August 28, 2006 1. The .dng files of the M8 cannot be precisely identical to those from the DMR - IF the 1.33 crop and 10.5 megapixel expectations are correct. Different number and pattern of pixels. 2. BUT my understanding of the .dng format is that the information such as number and pattern of pixels is recorded in the metadata of the file, precisely so that any software that can read a dng file can read ANY dng file - even from cameras it has never be designed for. Therefore if Leica and their digitizing partner have done their jobs in setting up the .dng encoding, M8 .dng files should be readable without update by any software that is .dng-compatable. The "details" that RAW software writers have to reverse-engineer for themselves from the camera-makers RAW formats (NEF, SR2, etc.), and redo for each new format - are incorporated as "instructions" right into any .dng file - that's part of the beauty of the format.

Unless you are using Apple's Aperture!

rosuna Posted August 28, 2006 Share #5 Posted August 28, 2006 Apple will present something the day before the opening of Photokina. Perhaps the Aperture 2.0 is announced and shown for the first time. Link to post Share on other sites More sharing options...
modschiedler Posted August 28, 2006 Share #6 Posted August 28, 2006 I always thought that dng is dng is dng – otherwise it wouldn’t deserve to be called a "standard". Am I wrong? Link to post Share on other sites More sharing options...
adan Posted August 28, 2006 Share #7 Posted August 28, 2006 Advertisement (gone after registration) Andrew N. Sounds likely - but that just means Apple screwed up the writing of Aperture, not that there's anything wrong with the .dng format. That's why I specifically wrote 'any software that can read a dng file..." rather than "any software....". If Aperture can only read SOME dng files, it is not dng-compliant, and thus doesn't qualify. That's why I stick with Adobe products - they know what they're doing. Marc-Jurgen - all dngs files are equal - but not all RAW processors are. Apple screwed up something in Aperture - Leica and Adobe are doing just fine. Link to post Share on other sites More sharing options...

osera Posted August 29, 2006 Author Share #9 Posted August 29, 2006 I always thought that dng is dng is dng – otherwise it wouldn’t deserve to be called a "standard". Am I wrong? Well, I thought so too. But it is my understanding that for some (maybe all?) raw processors, they can deal with .dng files as long as they have some prior knowledge of the details of the file. I know that Rawshooter was like that. It could read dng files created by or from cameras that it already "knew" about. New cameras required software updates, even if they were producing dng files. There was some explanation for this that I didn't really understand, although it seemed to be to go against the basic concept of dng open format.

nemeng Posted August 29, 2006 Share #10 Posted August 29, 2006 ... Rawshooter was like that. It could read dng files created by or from cameras that it already "knew" about. New cameras required software updates ... My understanding is that DNG files store two kinds of data: (1) the actual linear image data captured by chip and (2) camera-specific info such as its identity and how the data is structured etc. By looking at "(2)", any RAW converter can make sense of the image data stored in "(1)". Thus if the RAW converter is written properly, then it should be able to interpret DNG files from new cameras. This is what the Photoshop CS Camera Raw plug-in v2.4 does, which was released back in January 2005. It can cheerfully open DNG files created from (say) the Olympus E500, which only became available nine months later. The problem with Aperture is that it ignores the data in "(2)". So you're out of luck if you try to use it with a camera it doesn't recognise. Link to post Share on other sites More sharing options...
