Solution for DMR files in Aperture......DMR2M8

A few months ago, Andy Barton suggested using the core of CornerFix to modify DMR files to look as if they were M8 files, and so allow Apple's Aperture to read them. As part of building CornerFix for the Mac, I've now done so.

 

You can download a first beta version of DMR2M8 for the Mac from here:

 

SourceForge.net: CornerFix

 

Just follow the "Download CornerFix" link, and then select the DMR2M8 package

 

Note that in order to get Aperture to read the files, two changes needed to be made to DMR DNG files:

 

1. The camera name in the EXIF data is changed to M8

 

2. The DMR's 16-bit data is truncated to 14-bits. Note that the files isn't compressed as is the case for the M8

 

You will need the latest version of Mac OS and Aperture - the ones that can read M8 files(!)

 

In order to install the software, just unzip and drag DMR2M8.app to your Applications folder.

 

As this is a close cousin of CornerFix, you can even still devignette you images :D

 

Please read the QuickStart document for important usage information.

 

Enjoy

Hi Sandy,

 

You've done wonders, the 16bit was what was stumping me getting blown highlights to display correctly in Aperture.

 

Any chance you can re jig a version of this not to rename the exif camera tag but just converting to 14bit? then I can give a profile based on the matrix 1 & 2 values for both the R8 & R9 DMR's with reasonable colour accuracy?.

Yes, shouldn't be a problem - I'll try to do something tomorrow....

Done. This is now available in the same place, as version 0.9.1.3. I've implemented it as a user selectable option in Preferences.

 

Note:

 

1. In order to disable the overwrite of the EXIF data, you must go to Preferences -> General, and deselect overwrite.

 

2. If you change the overwrite enable/disable setting, you MUST reload any file you have open - the setting only applies to files opened after you change the setting

 

Enjoy

OK here we go again, another hack of Aperture to use the R8 & R9 DMR files.

A huge thanks goes to Sandy for cracking the 16bit limitation I was having problems with. Sandy kindly placed an option inside CornerFix to leave the Exif tag untouched and not use the M8 profile. I have 2 profiles based on the Matrix values inside the DMR DNG so colours should be better than those form the M8. Depending on which R body you use you'll need to copy the relevant profile or both into the raw.plist.

 

Further info for hacking the raw.plist can be found here http://www.l-camera-forum.com/leica-forum/leica-m8-forum/30398-m8-apple-aperture-resource-info.html

 

I hope Andy won't mind me using the images he gave me some time ago to show the results.

 

Firstly Andy gave me a raw file and a jpg,

 

First is what happend with the 16bit colour depth in aperture

 

Second is the raw file converted with Sandy's application brought into Aperture and exported for web no adjustment.

 

Third is Andy's Jpeg resized for web.

 

 

For you DMR users who wish to use Aperture, try the profiles and don't forget to de select the option in CornerFix for overwriting the camera name with M8. If you don't like the conversions, no harm! just re-enable the overwrite and continue using the M8 profile

 

Thanks again Sandy, this one is down to you. Respect :cool:

Of course not - this is why I sent them to you.:)

 

I have to say a big thank you to both of you for working on this, on our behalf. Many thanks.

Here are two versions of the same RAW file.

 

First, using Lightroom and PSCS3

 

Second using Sandy's v 1.2 DMR2M8 application, and without Eoin's Raw.plist hack (I couldn't get v 1.3 and the hack to work)

 

Lightroom 1.1

Aperture with DMR2M8 hack

 

 

Note how the reds are boosted in the Aperture version. I need to try the RAW list edit again, to get the R8 colours to be more accurate, but this is looking very promising.

 

Thanks, gentlemen!

Just following on from Andy's problem, I neglected to say if at some time in the past you had hacked the raw.plist to create an R8 entry you need to delete that entry before copying in the new entry. Without deleting the entry first it will corrupt the R8 entry and give you an unsupported image format error. Sorry! :o

There is a new version of DMR2M8 available at the usual place.

 

This is a bug fix release, 0.9.1.4, which solves a bug that could cause problems when processing files with certain Unicode characters in the file name, e.g., some European accented characters

OSX Leopard has, unsurprisingly, broken Eoin's plist hack.

 

It seems to have deleted the plist altogether (at least from the place where it was previously stored)

 

Edit: Update - even the DMR2M8 solution doesn't work anymore. Time to give up on Aperture altogether.

Interesting, I don't have leopard and won't have it till my new MBP arrives and depending on if they installed leopard on new MBP for delivery after the launch date.

 

I'll have a look at it then and report back

Andy,

 

Unfortunately, I don't have Leopard either, but when you say "even the DMR2M8 solution doesn't work anymore", can you be a bit more specific?

 

Regards,

 

Sandy
