EXIF data - e.g., Flash Exposure Compensation - is it hidden someplace?

I see in LR various pieces of EXIF data, but can't find FEC. Is it hidden someplace? Thanks.

Rob, this looks very good! Would any possible bugs in the code be limited to problems in searching on or viewing metadata, or does it have the potential of corrupting the LR database itself? From my limited understanding of the internals of how LR works, it seems to me that plugins would not be able to damage the LR database. Thanks!

Flash Exposure Compensation Value Not Displaying in EXIF Info

When adjusting Flash Exposure Compensation on Nikon D4 camera (not on the Speedlight) the set value is not showing in EXIF Field in Aperture 3.4.1. It always shows as a 0 value regardless of camera setting. When I open the .nef in Nikon View NX (v2.2.4) the set value for Flash Exposure Compensation is accurately shown in the EXIF info. Have tried editing the Aperture EXIF fields (removing Flash Exp Comp and re-entering it) but, to no avail. Has anyone seen this, or know of a solution? Are any D800 users seeing the same thing?
Thanks!

Greg,
All the references to the element "rdf:value" in the XMP Specification
Part 1 appear in discussions about the implementation of XMP Qualifiers.
Page 21,
The presence of property qualifiers is indicated by a special use of
the rdf:Description element. Each rdf:li array item in the example
contains an rdf:Description element, which itself contains the
following:
-- a special element called rdf:value that represents the value of
the property
-- zero or more other elements that represent qualifiers of the value.
In this case, there is one property qualifier called ns:role.
Page 26
Other qualifiers cause the RDF for the qualified property to look like
a struct with a special rdf:value field. The presence of rdf:value is
what denotes this as a qualified property.
Page 28
For qualifiers other than xml:lang, RDF forces the qualified property
to look like a struct with a special rdf:value field that contains the
actual value from the XMP Data Model. The other fields of the fake
struct are the qualifiers. The presence of rdf:value is what
distinguishes a real struct from a qualified property.
I assume that you are not trying to implement XMP qualifiers. Perhaps
you should use vra:value instead?

Flash Exposure Compensation Metadata

Please allow Bridge to read and state the degree of Flash Exposure Compensation that a photo uses in its metadata. Currently, Bridge does not read this info for Canon photos but the info is in the picture.

Yes, yes and yes. Its a good thing I kept Breezebrowser

600EX Flash - 5D III. Flash exposure compensation.

How can I set the FLASH exposure compensation from the CAMERA. It appears that I have to set the exposure compensation on the back of the flash unit. I would like be able to change the FLASH EC settings from the camera, not the flash unit.
Solved!
Go to Solution.

Ok, I have my 5D III out with my 600EX-RT mounted.
Let's make sure you don't have terminology confused.
There are two different compensations... there's "explosure compensation" and "flash exposure compensation".
If you meter exposure with the camera and then use the rear dial (assuming you did not disable it) after waking up the metering system then the rear dial will change the "exposure" compensation (this changes the metering for the AMBIENT light reading that the camera reads -- ignoring the flash). So changing "exposure compensation" will not change the flash even if the flash is powered on and connected. It would only change the camera.
On the top of the camera, just in front of the top LCD screen, there are four buttons. One has a dimple on it. That button is the ISO & "flash exposure compensation" button. If you press that button, then the rear LCD screen should show you that the rear dial will control "Flash exposure comp." Turning the rear dial at that point will make the adjustment show initially ONLY on the camera LCD screen... UNTIL you press the 'Set' button in the middle of the dial. Once you do that, the rear LCD screen on the flash will show that you have the flash exposure compensation enabled (it will ONLY show this when you wake up the metering system... if the metering system is allowed to go inactive the flash will only display the netural compensation... but as soon as you re-activate metering it will display your exposure compenation as set on the camera.
Also... on the rear LCD screen there's a box just below the ISO setting that shows if you have flash exposure compensation set and the amount.
This is all being controlled only by the camera -- I'm not using the menu buttons on the flash itself.
IF I DO use the buttons on the flash to set flash exposure compensation then the camera is locked out. It will report what compensation has been set on the flash, but will not let me change it until I use the buttons on the flash to return it to 0.
Does that help and are you able to do this with your flash?

Flash Exposure Compensation

I am shooting RAW files with a Nikon D200 and SB-800 Flash. I use controls on SB-800 to adjust flash exposure compensation. When photos are imported into Aperture the flash metadata states "strobe return light detected". The flash exposure compensation field lists zero despite having set an exposure compensation on the flash. Any ideas?

Importing Canon EXIF data into Lightroom

Hi,
sorry if this is a stupid question...
I noticed that when using Canon Image Browser software, that the amount of image information is much more extensive than what I can see in both LR and in Bridge. As an example: In Canon Image Browser I get data for flash exposure compensation, in Bridge and LR I do not have detailed flash information.
Any suggestions?
Also, does anybody know if it is planned to add the feature where you can see the AF point(s) (again, I see it in Image Browser, but not in Bridge or LR)
Thanks,
VR

Most Canon's MakerNotes tags are "public secret", which means: there's no official documentation, but everybody knows them :-)
As FEC info resides in the same (MakerNotes) section as some other info (which is recognised by LR), it shouldn't be difficult for LR to show FEC value too. I believe there could be other problem...
LR should deliver same infos for all camera brands and maybe FEC value of some other brand isn't so easy to "decode". So, it wouldn't be "fair" if LR would show particular values only for some brand. There's no other reason I can think of.
In regard of focus points.. I don't miss that info at all -and even Canon's DPP doesn't show them up.

Viewing Metering Mode, Flash data, Exposure Compensation Values in Lightroom

Anyone know if it's possible to see the following data in Lightroom 2? I can view this data in the 3rd party tool Exifer (if I convert a pic to JPEG) but I think it would be very handy to see this in LR2. Anyone know how or if it's possible?
Focal point chosen
Metering Mode
Exposure Compensation Values
Flash data (Did or didn't the flash fire)
Shooting Mode (i.e. Manual, Av, Tv, P, etc)

Focal point is not possible. However, depending upon the camera model you should be able to see the others when the Exif metadata field preset is selected (see screnn shot below), and you should not have to convert to JPEG to do see Exif.

Problem Viewing Flash Exposure Data in Bridge

Hi Folks
When I view flash exposure data on my camera it will show me the flash compensation value I have set eg -0.7 or +2. When I download the images and view the metadata in Adobe Bridge (from CS3) I appear to lose this information. It will tell me that the flash fired or nor, but that is about it!
Is there anything I am missing here, or is it just a limitation of Adobe Bridge.
Any information would be gratefully received.
Regards

I have been looking for the same information in CS5. Although I can't find it displayed anywhere in the Camera Data you can find it if you really need to.
Choose File Info from the File menu and then go to the Raw Data tab. Use the search function to look for "FlashCompensation". I found it there for my Canon G11.
Painful but works if you really need it too.

Exif data from sb-800 flash (d70 camera)

Hi
Ive seen that aperture provides more exif data than iphoto or Photoshop elements. I did a test where I tried my various flash settings, ttl-balanced light, ttl (regular) but I don't see any differentiation in the exif data. This is important when reviewing images to see which I took using each setting, and learning which would be most useful in various sitations.
Anyone who has a similar setup or has used exif for these type of flashes? If so, please post and perhaps let me know what I'm missing here.
Thank you
Greg

Hi
Thanks for the reply, and yes Capture NX does have this information there, I find this very useful for analysis of flash photos and what works best in different settings.
May I ask:
1. I have a VR Nikon 70-300 lens but the vr data is blank even in Capture NX (although I downloaded 1.3.1. Do you have a vr lens and was this data available?
2. At a first glance, it appears aperture has more exif data than Capture but perhaps the specific data that Capture NX has is more useful?
3. If you've used both Capture NX and Aperture (and/or other apps) for those with Nikon cameras which did you find most useful?
Thanks

IPhoto exif data

Does iphoto strip some of the exif data from photos? I'm currently using iPhoto as my photo management tool and I also use photoshop elements to do some editing. When I view the photo info in iPhoto, it seems like the data is pretty skimpy.
Specifically, I'm looking for white balance data (right now). I'm taking a photography course and was testing different white balance settings... and those settings aren't showing up in my photo info. I REALLY don't want to have to buy another program like Aperture, especially considering I already have photoshop. If iPhoto has this info somewhere, can you help me find it?!?!
Please help!! Thanks!
Erin

Erin:
iPhoto doesn't strip the data it just doesn't read all of it. You can get all of the data read by using a 3rd party application likeEXIF Viewer. Just put the app in the Dock and drag a photo from iPhoto onto it. It will open and give you the following information:

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.≤br>
Note: There now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

3.4RC not exporting Exif data in jpegs?

I just checked and there seems to be no Exif data in my exported jpegs, even though Minimize Metadata is not checked. Anybody else experiencing this? DId I miss some new setting or way of specifying this? Win 7 64-bit, 64-bit LR.

In terms of the XMP standard, the EXIF schema properties have been omitted from the LR 3.4RC version of the image. For example, the 3.3 version has the property XMP:DateTimeOriginal, while the 3.4RC version does not. See below for all differences in the metadata.
I think this may be a bug. The XMP standard was designed to encapsulate legacy metadata such as EXIF, and it was intended that the XMP metadata contain duplicates of the EXIF properties. Unlike the EXIF standard, XMP allows multi-byte characters and time zones, so not exporting the XMP EXIF properties means that it won't be possible to export multi-byte characters and time zones.
Differences in metadata:

Any way to change/replace EXIF data like the original date of photo?

I'm importing into Lightroom several thousand photos I took with my first digital camera, back in 2000-2004. It's all gone very smoothly. But here's my problem:
In my old workflow, photos I spent time editing wound up as TIF files, and whatever program I used to edit them stripped out the EXIF information from them. As a result, for example, a photo which was actually taken on March 4, 2001 will have EXIF information showing it was taken on March 10, 2001, the date on which I edited it and made the TIF. All of the other EXIF data is stripped as well, the exposure data, lens information, ISO, whether the flash fired, etc. The TIF file basically seems to have no EXIF data other than the file size and my name.
I can live without the other info, really, but the changing of the information about the original date/time means that the TIF file doesn't sort next to the original file in Lightroom, which I'd like it to do. There's not thousands of photos for which I have TIFs, just a few hundred at most.
Is there any way, with a plug-in or some external program, to copy the EXIF information from the original program and insert it into the TIF file?

I'd suggest just using ExifTool.
The command is:
exiftool -tagsFromFile {SRCFILE} {DESTFILE}
So, if you have a tif sans exif named my.tif, and an original jpg with exif named my.jpg, it would be:
exiftool -tagsFromFile my.jpg my.tif
There may be a batch-y way to do this with exiftool, or you could make your own batch file to do this in bulk...

How to copy EXIF data for a single photo?

Hello,
I post photographs to a few different photo forums for community comment and critique. Including the basic technical data for each photograph is common and having to type it in manually is tedious. Is there a quick and easy way to copy or extract basic EXIF data (exposure, focal length, EV, ISO, exposure program, metering, make, model, lens) for a single photo to the clipboard? The information is all over LR I just can't determine how to get it out quickly.
Thanks for your help!
Best,
Eric

I don't see anyone provided you with an answer.
The hard way is to export the metadata to the file and use an external program. There are many programs that manipulate metadata. I haven't wanted to export it in the way you describe.
What operating system are you on?

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.

IPhoto '08 loses exif data when exporting RAW to JPG

I'm using a Canon 40D shooting only RAW. I just recently noticed that when I export to JPG, iPhoto loses quite a bit of important EXIF data, including, aperture info.
Is this a known issue, or is it something unique to my system?

I guess I misworded it. I understand that the info doesn't go away or come back. Either there's a problem in both Finder and flickr (I've uploaded the file to flickr.com) where neither finds the info in the jpeg or there's a problem in the way iPhoto writes the EXIF data to the file.
Today, I downloaded EXIFViewer for an alternate look at the EXIF fields and the aperture data is there according to EXIFViewer. So, now I think the bug may be with flickr. Can't really call it a bug in Finder, since the expected functionality for finder is not to get "aperture info", but "More info."
In any case, these are the fields in the More Info:
|RAW:Name_|_RAW:Value_|_JPEG:Name_|_JPEG:Value|
|Dimensions|2586x3892|Dimensions|2586x3892|

|Last opened|Monday, May 19, 2008 6:31 PM|Last opened|Today, 9:31am|
And the meta info on flickr is here:
http://www.flickr.com/photos/carloscervantes/2536040124/meta/
Again, no aperture data in either flickr or Finder.

EXIF data - e.g., Flash Exposure Compensation - is it hidden someplace?
