Beyder28 Posted August 27, 2011 Share #1 Posted August 27, 2011 Advertisement (gone after registration) Hello all, I just got a Summarit 1.5 from 53' and I would like to know what is the fastest and or easiest way to edit the exif data in Aperture 3 to show that lens and not the Summilux 1.4 which is the closest one to it on the M9 menu. I currently use Cornerfix to just get that extra exif data like the approximate F-stop etc. on the photos before I transfer them into Aperture 3. Any help would be appreciated. Thanks.

Advertisement Posted August 27, 2011 Posted August 27, 2011 Hi Beyder28, Take a look here Exif Data. I'm sure you'll find what you were looking for!
stunsworth Posted August 27, 2011 Share #2 Posted August 27, 2011 Try Googling "Exif editor". Link to post Share on other sites More sharing options...
Beyder28 Posted August 28, 2011 Author Share #3 Posted August 28, 2011 I googled it and got nothing of what I was looking for which is why I posted it here. When you google it (for mac) it gives you a bunch of 3 and 4 year old sites that give you largely complicated command code freeware programs and most are for Windows anyway. The rest of the results are viewers and not editors. I want an easy to use editor which will let me put in the right lens into the EXIF Data among some other fields.

hoppyman Posted August 28, 2011 Share #4 Posted August 28, 2011 I think that EXIFtool is seen as the king of EXIF viewers/editors. It is however command line based and I haven't found a GUI addon that will do what I want there either. I got EXIFtool working following some detail in this earlier thread http://www.l-camera-forum.com/leica-forum/digital-post-processing-forum/135236-changing-lens-info-exif.html However despite this method appearing to add the metadata I wanted I still cannot get Lightroom to recognise it. I made new copies of the original files by copying directly from the card to a new directory , using the EXIFtool from the command line and then importing these as normal in Lightroom 3.41, using copy as DNG, but it still does not show the added data. When I look at the metadata of the edited files in EXIFTool the new lens data reads correctly but it STILL doesn't show up in LR. I've cleared the cache and re-read the metadata in LR to no avail as well. Any suggestions more than welcome to me as well. I think that this is a recurring topic of interest to a few. I accidentally shot 200 frames with lens detection off and would like to correct these myself. Link to post Share on other sites More sharing options...
Beyder28 Posted August 28, 2011 Author Share #5 Posted August 28, 2011 Yea, ExifTool is the one I tried using but does not work for me either. Plus, who the hell still uses command lines? Link to post Share on other sites More sharing options...
hoppyman Posted August 28, 2011 Share #6 Posted August 28, 2011 One of the group's knowledgeable computer folks earlier offered to take a look for me. I'm sure that he will share anything useful that emerges. However after sorting out the basic errors I made using EXIFTool via the command line the edits appear to have been successful. That is to say the new versions read correctly in EXIFTool. I haven't determined as yet why Lightroom is not displaying the new data though. To recap on that for clarity: I copied new versions of the original files directly from the card to a new folder and I included a copy of the EXIFTool exe in the same folder for simplicity. Following O1af's posts in the earlier thread, I typed a simple txt file including the specifics for the lens I wanted and put a copy in the same folder. ....................................... # Adds lens info for Summilux 50 on M9 -n -MakerNotes:LensType=32 3 -XMP:MaxApertureValue=1.4 -EXIF:MaxApertureValue=1.4 -EXIF:FocalLength=50 -EXIF:FocalLengthIn35mmFormat=50 -overwrite_original_in_place ..................................... I used ..................................... exiftool -@ Summilux50.txt L103776.dng L103777.dng etc on the command line .................................... After that by dragging the files onto the EXIFTool shortcut I saw the correct information now displayed. Deleting the old files, clearing the cache and importing those edited files anew with Lightroom 3.41 the metadata still is missing the lens name and focal length (or rather Lightroom is still not displaying it).

hoppyman Posted August 31, 2011 Share #8 Posted August 31, 2011 Well yes! The reason I detailed everything was if one of our experts might look and tell me what I am doing wrong. I have 200 files I want to fix. But I think that I understand how EXIFTool is meant to be used now (from command line and via dragging files onto shortcut) and it did exactly what I wanted it to do. So my error now is somewhere in the importing with Adobe Lightroom. Working on it. All knowledge is golden. Link to post Share on other sites More sharing options...

Delfi_r Posted September 1, 2011 Share #10 Posted September 1, 2011 I use a little Automator APP along Exiftool, so you can drop a folder to the App icon and all data is changed. I use it to allow Apple Aperture to get the lens name and aperture on their designed place. Link to post Share on other sites More sharing options...

Why not simply include the lens name, or an abbreviated version, in your keywords? Additionally, set up a User Profile named 50Sumrt, or your choice of identifiable code, with appropriate user settings. You can experiment to find the best choice of lens performance settings which suit you. Certainly the keyword solution would be my first choice.

Delfi_r Posted September 2, 2011 Share #13 Posted September 2, 2011 It was send to me by Dirk from JapanExposures, I was waiting that he publilsh his procedure, but it's a ShellScript wit two main versions, one generic and other lens-especific. The Lens specific code (for not coded lenses) is: for f in "$@" do exiftool -P -overwrite_original -FocalLength=28 -FocalLengthIn35mmFormat=38 -xmp-aux:Lens="Leica Elmarit 28mm f2.8 ASPH" -tagsfromfile @ '-xmp-exif:ApertureValue<ApproximateFNumber' -MaxApertureValue=2.8 -Lens="Leica Elmarit 28mm f2.8 ASPH" "$f" done The Lens, FocalLengt, FocalLengthIn35mmFormat, MaxApertureValue, are the variables you should change from one lens to another. There is another Genneric script for coded lenses, I'll need to find it out because I have a working version that defaults to the Perar Super Triplet if there is no data coded. do exiftool -P -overwrite_original -tagsfromfile @ '-xmp-aux:Lens<LensType' -tagsfromfile @ '-xmp-exif:ApertureValue<ApproximateFNumber' -MaxApertureValue=3.5 -Lens="MS Super Triplet Perar 35mm f/3.5" "$f" done finally there was a third script that i have'nt used that allows to select manually the lens over a predefined set. But I prefer the single lens approach as I can move the selected DNG to a folder and drop this one over the corresponding Automator App Icon. Link to post Share on other sites More sharing options...
rickp13 Posted September 2, 2011 Share #14 Posted September 2, 2011 maybe adding a 6-bit code to the lens flange or LTM adapter would take you one step forward? contact one of the local leica specialists mentioned here in the forum for assistance. cheers rick Link to post Share on other sites More sharing options...
Delfi_r Posted September 2, 2011 Share #15 Posted September 2, 2011 Yes, coding it's the preferred way when the coding is available, but the Perar is not coded because it should be redundant, and other lenses are not mine or have not codes (the Telyt lenses for example) This way I can code even images taken with the Visio, Bellows and lens head or projector lenses or which ever I use.

I don't see how putting in keywords about a lens will actually change the exif data?? I understand that I can put the lens name in keywords but that was not my question. I want to change Exif data not insert keywords. Link to post Share on other sites More sharing options...
