richfx Posted January 25, 2010 Share #1 Posted January 25, 2010 Advertisement (gone after registration) I'm running Aperture 2.0 with Snow Leopard. Aperture is not showing f stop and other metadata information for M9 DNG files. I spoke with Apple, and they said it's a Leica issue. Aperture does include this metadata information for RAW D-Luxe 3 files. Any suggestions? Link to post Share on other sites More sharing options...

mby Posted January 25, 2010 Share #2 Posted January 25, 2010 If LR3 can do it, Apple should be more explicit what exactly is Leica's issue... Link to post Share on other sites More sharing options...
holgerf Posted January 25, 2010 Share #3 Posted January 25, 2010 The normal data field to carry the f stop will always be empty because there is no communication between the lens and the body to submit the manually set f stop. However Leica guesstimates the value (so-called g-stop) by comparing the metering result with the amount of light that is registered by the small blue sensor near the red Leica logo. There are some threads dealing with this matter. Lightroom uses this value to support a value for f stop with a tolerance of 0.5–1. You may read about the the m8 metadata project here.

richfx Posted January 26, 2010 Author Share #4 Posted January 26, 2010 Thanks, Holger. Your analysis makes perfect sense. Is there any other way (other than taking notes for each photo) to keep track of exposures for M9 DNG files? Rich Link to post Share on other sites More sharing options...
sandymc Posted January 27, 2010 Share #5 Posted January 27, 2010 Thanks, Holger. Your analysis makes perfect sense. Is there any other way (other than taking notes for each photo) to keep track of exposures for M9 DNG files?Rich CornerFix has the ability to update the DNG files's aperture field with the estimated aperture. But that's an extra processing step. Sandy Link to post Share on other sites More sharing options...
ho_co Posted January 27, 2010 Share #6 Posted January 27, 2010 rc, I think Apple may be on questionable ground saying it's Leica's problem. As Sandy said, the M9's data are in the DNG, but they're obviously not where Aperture expects them. As Michael said (post #2), Adobe products decipher the data just fine. And I think that Capture On does as well. So there's no reason Aperture shouldn't. IIRC, one thing to keep in mind is that for Apple products, all RAW conversion is done by the system, not by the application, so any changes would require an update to the OS, not to Aperture. Have you tried running Adobe's free DNG Converter? (At the moment, it's the first item in the list at http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Macintosh.) Use the M9's DNG as input to the DNG Converter, and the output will be a more compact DNG than the original. Maybe when Adobe massages the data to the more standard DNG format, it might also put the aperture estimate where Aperture can find it. (I don't have an M9, so I'm hoping.)
