Exporting RAW to JPEG, losing EXIF data

Hi,
When I am exporting a RAW image from Aperture to a JPEG image I'm losing metadata. Specifically: Lens, Serial #, Flash exposure and focus data. I always select 100% JPEG with the "include metadata" checked.
Any suggestions or is this a bug?

I know this is an old thread, but I have the same problem and am hoping perhaps to get some new feedback. I also have used all the same settings,
the best quality settings that I can do on export, but the quality I get when I convert to JPG is very poor. I do save at 100% because I want to send some of my images to stock agencies that want JPGs but at the very best possible quality. I have experimented in changing the resolution to 300, resizing to 18MP (which is the native size from my camera (Canon 7D), leaving the resizing box unchecked, and tried all all levels and types of sharpening, and none of these settings makes any improvement. I honestly do not think this is an issue of color calibration. The images that I get when I convert from RAW to JPG are are very poor quality, but not so much noise as they appear pixelated. I am going to try to attach a screen capture of a RAW image and a JPG that has been converted. Realize there is a bit of loss of quality in both of these images as they were done by the print screen function, then saved as BMP and then JPG..But doing it this way actually produced a much better quality image than exporting the RAW file to JPG in LR3. Both of these images were saved at 100%
The image at the top is a small segment of the RAW capture at 100% and the bottom one is a segment of the same area of the exported JPG at 100% Note the writing and how it is very pixelated. I think you would agree that it is quite a deterioration in quality. Any suggestions you have would be greatly appreciated.
Thank you.

LR 1.3 Export of NEFs to JPEG Loses EXIF Data

When I use Lightroom 1.3 to export Nikon RAW (NEF) image files to a new directory as JPEGs, all of the camera EXIF data is missing in the exported JPEGs created by Lightroom.
In my Lightroom Catalog Settings, every option is checked on the Metadata panel (Include Develop Settings inside Metadata in JPEG...., Automatically write changes into XMP, and all Metadata browser categories).
On the Lightroom Export dialog, File Settings Format is set to JPEG, and Minimize Embedded Metadata is not checked.
My images files are from a Nikon D200.
I run on Windows XP SP2.
Any suggestions, or is this a bug?

What are you using to look at the metadata? If you do not check minimize metadata I always get everything written. Some programs cannot see the metadata though.
>In my Lightroom Catalog Settings, every option is checked on the Metadata panel (Include Develop Settings inside Metadata in JPEG...., Automatically write changes into XMP, and all Metadata browser categories).
This is irrelevant. For the exported jpeg, the only thing that matters is the export dialog. Also you should generally NOT enable automatically writing XMP data as it will slow down lightroom considerably (see the FAQ and the sticky threads).

Batch convert Raw to jpg with EXIF data

I would like to batch convert RAW images files to jpeg format while preserving the EXIF data. Is there any way to do this with the built-in apps in OS X Mavericks?
This used to be possible with Preview.app using the "Export Selected Images..." command. However, as of Mavericks, that command does not correctly copy EXIF data for the individual images. Instead, the EXIF data for the first image is used in all of the exported images. So Preview.app is now pretty much useless for converting batches of RAW files.
Can anyone point me to a workaround in Preview.app, or an alternative way to do this conversion in Mavericks?
I should add that I don't want to import all my images into iPhoto. I prefer to use regular folders to organize my images rather than the walled library that iPhoto creates.

I used iPhoto for many years and found it to be cumbersome and more trouble than it was worth. It did not let me manage, organize, rate, tag, and edit my photos in any way approaching convenience.
Hate to say this for the 3rd time, but use Canon's "DPP" (Digital Photo Professional).
With it you can "manage, organize, rate, tag, and edit [your] photos" as well as batch convert to jpeg or othet formats.

Exports aren't showing the EXIF Data

I just started shooting in RAW and today I exported some pictures to post on DPReview. The pictures did not include the EXIF data and I would like to include that information. Is there a setting I need to select prior to export so this data will be included? Thank you!

Use the setting in the export dialog.
You can choose from the dropdown menu e.g. copyright only or all metadata.
Also ensure DPreview is not stripping out metadata when you upload files.

How to export RAW/developed jpegs to jpeg, while keeping unmodified jpegs as originals?

Hi all,
I'm new to LR and can't work out how to get the export setting working as I want. What I want to be able to do is:
1. Import a number of photos into a collection (a mix of RAW and jpeg)
2. Develop the photos that I deem necessary
3. Export the whole collection to a specific folder on my hard drive as jpeg, but for the jpegs in the collection that I have not developed, I want to keep as original
I realise I could just export the developed versions as jpegs, and then manually add the unmodified jpegs, but this seems a bit fiddly and unnecessary. Is it possible to do what I'm trying? I'm using LR 4.1.
Many thanks in advance!

I want to create a collection in LR. Then after developing certain images, I want to export the whole collection to different location on my hard drive, while converting the developed files as jpeg, but keeping the non-developed files as originals (but still exporting them to the location). So I would have my 'master' folder in which I keep all my originals, and then a separate folder just for a specific collection, all in jpeg. The reason I want a separate physical location is that I have that location set to automatically sync with cloud storage, so others can view it.
What I was hoping to see when exporting my collection as jpeg was an option for something like 'keep undeveloped jpegs as original'.
Doesn't look l;ike I can do exactly what I want to. I'll find a way I can work with.
thanks for all your help!

Exporting RAW into JPEG, color differences

I've done a lot of searching in these forums and I can't find a solution to my problem. I just spent 30+ hours editing a set of 123 wedding photos in RAW file format. When I export to JPEG, the colors change on just about every photo. I understand that if I would have correctly set up the camer calibration prior to editing, this would have possibly solved my problem. However, the photos are already edited. When I export the files in TIFF, they look fine. It's just the JPEG file format that changes the look of my images. I'm using Lightroom 2.3. My last brainstorm involved importing the already edited TIFF files and then trying to export those into JPEG, the color format was still off. Can anyone Help?

What program do you use to look at the jpegs?
Is your screen calibrated?
What OS are you using?
There is a free upgrade available for you to the latest LR2 version 2.7. Win and Mac

Exporting RAW to JPEG and TIFF

Evaluating LE to hopefully improve some workflow. I noticed however, that when export to a JPEG or TIFF format the file size seems much smaller that I'm accustomed. A D100 9.5MB RAW file converts to appx 2.7Mb JPEG at 100% and appx 7MB in TIFF. Currently when I convert I get a 17-20MB JPEG. I'm I missing something in the setup or is this the larger file size LE produces.
Murray Edwards

Excuse me Lightroom. I currently use Portfolio 8 to review and tagged a large number of images for production. They have a conversion process that allows you to convert a NEF file to JPEG or TIFF. When converting to from a NEF file that is appx 9.5MB in size to a JPEG at 100% @300DPI which is what my clients require, it produces a a JPEG file that ranges from 17-23MB depending the amount of information. But I still have to pull that image into editing SW to do some cleanup or slight exposure adjustments. It was my hopes that by using Lightroom, I could slimline a couple of these processes. But if LR only provides a exported JPEG file size of what I've seen thus far, then I would unable to accomplish this.
Is this better clarification of my question?

Crashing when exporting Raw to Jpeg Windows

when converting from raw to jpegs sometimes my computer crashes completely, a complete stop!!!!
other times it comes up with problem and needs to shut down listing
AppName: lightroom.exe     AppVer: 3.6.0.10   ModName: msvcr100.dll
ModVer: 10.0.30319.415      Offset: 00010b90

ModVer: 3.6.0.10   Offset: 001fc314
no phone was connected to my pc, the problem is when i run up lightroom, sometimes i can use it then it may suddenly crash the computer switching off completley, other times it says lightroom has a problem and needs too shut down the bout info is what is shown as the problem. hope this helps.

Export Raw Files and keep XMP data

Hi,
I can export files from Lightroom to a folder and select original and I will get the raw file along with the xmp file. I therefore have any adjustments I made there with it. If I , however , export files to a folder and select original and chose Burn Files to Disc, the xmp files dont end up on the disc so I effectively lose all the work I have done to them in light room. Is there a way to fix this. Of course I can just export to a folder and then burn from there , but , I really like the way lightroom just burns disc after disc with no hassle. Burning discs from a folder is a hassle.
Any suggestions?
Thanks for your help in advance !

Hi, Gary. Have you tried converting to DNG, with xmp data embedded in it, then export & burn this?

Export RAW to JPEG too SMALL?

When I export a 9.5mb RAW/NEf file to jpeg, (100% quality, 240 ppi, default, original size), the jpeg file size is around 2-3mb.
If I convert the RAW/NEF file in the Nikon Editor, the jpeg version is around 6-7mb...much better.
I can't give my clients jpegs burned onto a DVD that are only 2-3mb?? Especially if they want good 8x10's, or 11x14's!! Not very professional.
Is it compressing it more than Nikon Editor, or am I missing something?

You should look at the files, not at their sizes. You cannot judge quality from filesize. There is no reason you couldn't get an outstanding 12x18 from a 2 MB jpeg file. Often the only thing bigger files do is take up more space.
>Is it compressing it more than Nikon Editor, or am I missing something?
You might be scaling by accident, but usually the image is just not very complex. The filesize you get in jpeg is related to complexity of the image. If you have large areas of solid color, the filesize will turn out small. If you have lots of noise and lots of complex shapes (like a grass field for example) you will get large files.

Exporting RAW to jpeg and keeping the develop changes?

Hi. I have my RAW files and catalogs safely backed up on external drives. Now I want to export some files to DVD's. I want these to be hi res jpegs with all the develop changes I made to them in LR, in case I ever want to go back and work on them again. I've done some tests and when I look at these exported photos in LR I see the photo as it was when I finished developing it but with none of my develop settings. How can I do this? Thanks

I understand the need for redundant raw files and catalogs, that's why I have 3 copies on various drives at home. I'm looking for off site storage (and I hate monthly fees to store them in the cloud) so I thought I'd put them on DVDs and store them at work. These are copies I hope I never have to use but if I do I'd like the originals and all my edits. I was hoping to use jpegs to save a little space.
JimHess says I can't do it and 99jon I tried your method but I must be doing something wrong because it didn't work. If you all tell me I should just use my OS to copy the original RAW files and the catalog to DVD (that how I backup to internal and external drives now), I'll do that, I was just looking for a way to do it in LR.

Exporting raw to jpegs

I have a few hundred images that I shot in Camera Raw, that I've modified and corrected in Bridge (CS3) & Photoshop (CS3). I now have a need to export them to JPG, and each way that I've tried has resulted in images that look nothing like what I see in Bridge.
1) I first tried exporting them with a batch file that I created (saves as jpg @ quality 12). This results in my images having a very yellow tint, compared to with the originals in Bridge.
2) Used the Image Processor under (Tools -> Photoshop). This resulted in very washed out images by comparisom.
Any help/suggestions would be great!
Thanks

Export of RAW files loses EXIF data

I am having a problem when I export files out of the PSE Organizer from RAW format to JPG that I am losing EXIF data on the resulting JPG file.
I am using PSE 6 on Windows Vista and primarily manage my images in RAW format (Nikon D300 NEF) within the Organizer. I am using the latest Adobe Camera RAW plugin ver 5.1 but I have tried this with the last three Camera RAW plugin versions without any difference.
I typically need to get the RAW NEF images into JPG format to post them to my blog so I normally select several NEF files at once within the Organizer then CTRL-E (or File, Export, As New Files), select JPEG, then Export.
The resulting JPG file has no EXIF data for the camera (e.g. Camera make, model, f-stop, exposure, etc) that was on the original NEF file. I am determining this by right-click, Properties, Details on the file within Windows explorer.
Other tests I have done to diagnose this are:
1. Opening an NEF file in Full Edit mode from the Organizer then doing a File, Save As (JPEG), the missing EXIF data *does* get saved properly. The problem with this approach is that it is not suitable to export hundreds of NEF files.
2. I downloaded a trial version of PSE 7 and it behaves identically to PSE6 in this test.
3. I downloaded a trial version of Lightroom 2 and the export feature works properly in this test.
Any help would be appreciated.

My observations of what is happening is exactly what you are seeing with one exception about the XMP update. My reply that I posted about seeing the XMP file being updated was based on the observation that when I did a File > Write Keyword Tag the time and date changed on the XMP file as seen with Windows Explorer. I also looked inside the XMP file with a text editor and saw the updated comments and tags inside. See this section of the XMP file that shows the comments and tags: ------------ <rdf:Description rdf:about="" xmlns:dc="http://purl.org/dc/elements/1.1/"> <dc:creator> <rdf:Seq> <rdf:li>Baden Smith</rdf:li> </rdf:Seq> </dc:creator> <dc:rights> <rdf:Alt> <rdf:li xml:lang="x-default">Copyright - Baden Smith - All Rights Reserved</rdf:li> </rdf:Alt> </dc:rights> <dc:description> <rdf:Alt> <rdf:li xml:lang="x-default">Fishing boats sailing by our balcony at dawn in Zanzibar</rdf:li> </rdf:Alt> </dc:description> <dc:subject> <rdf:Bag> <rdf:li>Africa</rdf:li> </rdf:Bag> </dc:subject> </rdf:Description> ------------ My original question posted was about the export to JPG and not seeing the camera EXIF info being exported.

Aperture incorrectly duplicating exif data - how can I stop this?

The situation...
a) I have 2 cameras (Canon 5D, and a Canon 5D MII)
b) I imported photos from 2 Compact Flash cards (1 from each camera) where the file names (e.g. _MG_9670.CR2) clashed. (i.e. both cards used the same file numbering range)
c) Aperture imported the images correctly, however the EXIF data on both images match identically apart from image resolution. Aperture believes these photos were taken at the exact same date/time and with the same camera which of course is incorrect.
d) If I export the original files from aperture and use the finder 'Get Info' option I can see that the RAW files contain correct EXIF data, so the issue must purely be an aperture bug.
Question - is this a known bug and is there any way to work around this?
Unfortunately I have spotted this on some wedding photos I shot for a client so I have had to switch to Lightroom for some confidence in not loosing important photos. Hopefully if someone can provide a workaround before I get stuck into my editing I can switch back to Aperture that I am more familiar with.
Thanks
Adrian

Interesting problem. The duplicate filenames could be causing Aperture to get confused but I've never seen this myself. Do you have Do not import duplicates set in the Import pane? If it is not set and you set it does Aperture see the files on the second card as dups?
As a test, when you import from one of the cards (either one) rename the originals. Does the EXIF problem still happen? If not then you will need to rename one of the cameras files either on import or in the camera. I believe Canon allows you to set a filename no?
Also make sure to file a bug report with Aperture, Aperture->Provide Aperture Feedback, look for the bug report entry.
If renaming the files does not fix the problem post back.

Exif data lost?

whenever i work with RAW files in Aperture, i always loose the exif data. Even the camera make does not show up when i post to flickr. I have all updates for aperture.
My cameras are Rebel XT and Leica DLux3

what does the preset that you are using to export the images say about exif data ???
there is a checkbox that includes or strips the metadata for presets ...
check that first ...
