Lens-to-subject distance in EXIF data

I'm looking for lens-to-subject distance in my EXIF data (Canon 7D Mk II). Is it captured?And if so, how do I view it?

Hi wildimagesfla!
Thanks for posting.
The distance between the lens and the subject being focused on is not something that is captured and recorded in the EXIF information.

Subject Distance in EXIF Data

Now that LR 2.6 reads EXIF Subject Distance into the catalogue, does anyone know how this information can be added for images that have been imported using previous versions of LR?
Tony

Thanks Ian,
Read Metadata from File isn't the answer since doing this obliterates everything that has been added to the metadata since the original import, but does add the Subject Distance. I'm using RAW (NEF) files without xmp sidecars. If I save to xmp and then Read Metadata from File, it works. I just hoped there might be a simpler way to get the Subject Distance into the catalogue. I also have many jpg images in my catalogue (before I started shooting raw) and the xmp solution can't be applied to those, although I could save the metadata to the jpg files (I don't really want to do that either). I originally started with a Nikon D50 and those images have Subject Distance in their Exif data, so the information is there for all my images, I just need an easy way to get it into the catalogue.

Pentax lens type not displayed in exif data.

I have an SMC Pentax-DA 18-250mm lens, which I use on my K10D. I save the raw files in .dng format directly on to the memory card, then import them unchanged into LR.
LR has persistently refused to show the lens type in the exif data for this lens - other Pentax lenses that I have work fine, as do all the other lenses that I have used in the past. This applies to all LR versions, including the current v2.1 beta. It DOES correctly show the actual focal length used for the shot, and the 35mm equivalent.
The lens type data is definitely present in the .dng files - the Pentax supplied raw convertor shows it.
I know the lens is a relatively model from Pentax, but I bought it nearly a year ago now, and LR has undergone several updates since then - enough time for LR to catch up, I would have thought?
It is an annoyance, rather than a big deal, but I'd appreciate any thoughts or comments.
Cheers

I am testing Lightroom 2. I believe this problem is still occuring.
Can this be confirmed?

Cs6 focus distance in exif data.

cs6 doesn't save the focus distance in the exif data (Canon 7D) like cs5, is there a fix for this?

I opened your images in CS6 and CS5 this is what I see in file info:
CS5Cs6
Windows Explorer does not show Distance and Chrome does not show it either
Propoerties does in the cs5 not CS6

CS6 Bridge "Not Displaying Subject Distance Information in Exif Data"

In Bridge CS5 the "Subject Distance" information is displayed for Zoom lenses which report distance information, under the Camera Data (Exif) panel.
In Bridge CS6 either 64 or 32 bit, no "Subject Distance" information is displayed for the same files, which report this information under CS5 bridge.
I have checked that the "Subject Distance" is checked and turned on under the preferences section. Not sure if the data is either not being read or just not being displayed.

Sony: Lens Profile Creator knows the subject distance, ACR does not

When making a lens profile for a Sony alpha DSLR, lens profile creator identifies the focus distance, and processes each distance accordingly. However, when loaded in ACR (or PS lens correction filter), the software does not display the distance. Why can LPC read the subject distance and ACR cannot?

function(){return A.apply(null,[this].concat($A(arguments)))}

The Creator, however, determines / calculates the subject distance itself.
Is this a complicated way of saying "God only knows"?
In all seriousness, if one program can calculate a piece of info from a file, so could another. The designers may just not have chosen to dig so deeply into the manufacturer-specific data as to do so. Or, as appears to be the case here, the information is derived from known subject material in the image itself.

When I attempt to apply a lens profile in the Develop module the only choices are for the Fujifilm X100/S/T even though in the Library module the EXIF data correctly shows the camera as the X-T1 and the precise lens used to take the picture. How do I get

When I attempt to apply a lens profile in the Develop module the only choices are for the Fujifilm X100/S/T even though in the Library module the EXIF data correctly shows the camera as the X-T1 and the precise lens used to take the picture. How do I get the right profile available?

First, the required profile needs to be present. LR 5.4 supports the X-T1 in terms of understanding its Raw format, but will not come with a profile for every lens which can be mounted onto that.
A profile is made for each specific lens, as mounted on a certain camera. It can also be used with pictures taken on a different (reasonably similar) camera body than the one originally used during profiling. This is subject to the sensor format: you can employ a given lens profile made for full frame, on an image from a crop sensor behind the same lens - but not vice versa.
Next, the image type needs to correspond to the image type which has been built into the profile: Raw, or non-Raw.
Lightroom offers only profiles of the right type for the image(s) concerned. There are many more provided for correcting camera Raw, than for correcting camera JPG. That is also the case with additional profiles, e.g. those accessed via the Adobe lens profile downloader utility.
Finally, in the event that there simply is no profile out there for a given lens, it is not particularly difficult (though a little tedious) for the end user to generate one, using a further Adobe utility which is downloadable as a package, including a range of checkerboard calibration targets, each of which needs to be printed at a stated physical size.

Camera data subject distance missing in CS6

This is another strange problem. I noticed that recent shots with any of 3 Nikon cameras, D3, D4 and D300s lack the distance data in CS6 Bridge. But older shots do. I narrowed the change to about June 10, 2012. Before this they have the subject distance and June 12 pictures and later don't. It seems that this is the time when I configured or installed CS6 which was a free upgrade after getting CS5.1
When I open CS5.1 Bridge though, even the most recent shots have subject distance.

Curt Y,
Thanks for your response. I was aware of the thread you reference. In fact I have implemented the excellent workaround described by Paul Riggott in that thread.
Nevertheless that thread fails to provide an answer to the original question: Why is subject distance correctly displayed in Bridge 5 and that field completely absent in Bridge 6.
In my case this is true for both native NEF files and when the same file is converted to DNG.
It is true for both old and recent files and for files from D700 and D800 cameras.
In the case of these two cameras, the Subject Distance is found under the Makers Notes but is not found under the Exif data as reported by ExifToolGUI. This last finding confirms the observation of DLC (reply #4) in the cited thread.
However if one examines the advanced tab in file info, one finds the following:
In both Bridge 5 and Bridge 6 there is an entry under Exif Properties labeled "Subject Distance"
So the question remains: why is this datum displayed in the Camera Data (Exif) Panel of Bridge 5 but not in Bridge 6? And what can be done to correct this glitch?
Addendum / Correction
I have just discovered the following: Older (raw) files which had been previously opened with Bridge 5, regardless if they were edited or not, when now opened in Bridge 6 do show the Subject Distance in the Exif Panel.

Exif "subject distance", shows in Bridge 5, gone in Bridge 6

Just made the switch from CS5 to CS6. The Camera Data (Exif) panel in Bridge 5 gives me the Subject Distance value. In Bridge 6 that field is not shown. Under Preferences>Metadata, the Subject Distance field is check in both versions. What has happened to this datum in Bridge 6?

Photoshop not seeing lens model in exif data from A3 export

Hi, I am trying to use the lens correction features in CS5 but the lens type can't be read in the exif data of an image I've exported from A3. It sees the focal length and body type. The lens type is listed in the Metadata Inspector in A3. I took the image into iPhoto and checked "extended photo info" and the lens type isn't there either. This happens with at least 2 lenses. One prime and one zoom. Any ideas?

Hi again
Having played with metadata a bit more, it is possible to include EXIF data for the lens size etc.. eg...EF300mm f2.8L IS USM But it doesn't append the manufacturer's name, eg I use Canon, yet 'Canon' is not appended to the Lens data like it is to the camera name..
In the library Inspector click > Metadata > where it says 'General' click the down arrow, then click > Edit > from the window that appears click > EXIF > from the drop down list click > Lens (scroll down a bit)
The lens you used will now be appended to your data.
I have not tried exporting this to Photoshop so maybe you could post back if its possible to export this data to PS or not.
Maybe someone has information on this and can chip in here with advice....
Hope this is helpful....... Gerry....
PS to all reading this, I also noticed while playing around with this ( I have not delved into metadata too much since Ap2) that all my personal details like mobile number, address, email etc are all appended by default, I imagine my address book info has been used here.
A useful feature indeed while selling photo's, or if you intend it to be there..... but not so good if you are not aware it's there in the first place.....!
Just a shared thought to whom it may concern....... Gerry.

Leica Lens ID in EXIF Data

Recent upgrades to Aperture have resulted in the EXIF data no longer identifying the Leica lens used. EXIF only identifies "50mm" for example, whereas it previously identified the lens as "Summilux-M 50mm f/1.4 ASPH."
Apple professional support was unable to figure this out and never contacted me, despite promising to do so.
Has anyone solved this problem?
Thanks,
Rich

I'm seeing the same thing. I just ran exiftool on a RAW file and see this:
ExifTool Version Number         : 9.12
Lens ID                         : Summicron-M 35mm f/2 ASPH.
Red Balance                     : 0.583497
Scale Factor To 35 mm Equivalent: 1.0
Shutter Speed                   : 1/16
Circle Of Confusion             : 0.030 mm
Field Of View                   : 54.4 deg
Focal Length                    : 35.0 mm (35 mm equivalent: 35.0 mm)
I don't really know the EXIF spec so I don't know whether "Lens ID" is the standard field that should be used.

EXIF data LENS MODEL information is not displayed

I have imported my photos into Aperture 2.0.1 and notice that in the EXIF data, the Lens Model is blank. I know the information is in the RAW image file because when I open it with other RAW converters I can see the lens information that I used to take the shot. I am not sure why this information isn't showing up or how to get it to see it or display it.
Don't know if it matters but I shoot with a Pentax K10D.

The lens data doesn't appear for my K10D either so I guess it does matter. The images I'm working on were just imported into Aperture 2.0.1. I've switched between Raw 1.0 and Raw 2.0 with no change. The field is still blank. It's get the focal length right so I expect the data is there. I'll bet it works fine for most of the Canikons.
I really would like to be able to use this field for searching. I'll keep checking though.

EXIF data filtered when exporting to Flickr

I've noticed that some EXIF data seems to be filtered out when exporting photos to Flickr via Aperture's built-in Flick exporter.
For example, if I export same photo using Flickr's upload page, then using Aperture's built-in Flickr exporter, then re-download original back to my computer, the fields like "lens size" are missing from the copy exported by Aperture.
There's few other fields that are silently filtered out by Aperture. Looking at the differences between two copies of the same photo re-downloaded back from Flickr, examples include fields such as digital zoom, subject distance, focus mode, macro mode, firmware version, serial number, owner name (and the list goes on)...
While one could argue that some fields contain personal information, there's my real name on my Flickr account, so having serial number or owner name in EXIF data removed is kind of pointless for my use case. Also, there's tons of photos I exported in the past to various photo sharing sites containing these headers anyhow.
I'd really like to preserve some interesting and useful (technical) fields such as lens size or subject distance. Is there a way to tell Aperture "I don't care, the world already knows this stuff, don't filter EXIF info when exporting"?

Hi Raja,
Not sure, what version are you in, but must not be in latest.
You have to write a e-text to get csv/txt of the desired format.
By default, if you are not in latest version, you will see some data when you select csv without E-text template

Display subject distance in Lightroom metadata

The EXIF data in the Lightroom database includes SubjectDistance but this does not appear in the Metadata windows. It would be very handy if it was.
(forgive me if I have overlooked it).
(note: SubjectDistance is not recorded for all camera/lens combinations, eg 7D and Tamron does not)
As a further and natural extension, you could then easily calculate and display Depth of Field estimates (Near/Far limits and total DOF)

Digging deeper ...
The Lightroom database has a table called AgHarvestedEXIFData, which has columns for aperture, focal length etc but not subject distance.
There is also a table called agAdditionalMetadata. This has a column XMP which is xml format EXIF data etc, including <SubjectDistance>
So the data is in the database but not in the table which is used by the MetaData tab in the Default view option.
So why does it sometimes show for you?
The clue is the heading Shooting Info on your screenshot. I don't get that. However if I switch though to the EXIF option instead of Default the list of EXIF data fields changes, enough to make me think it is using different code. I think in some circumstances it is clever enough to extract the data from the XMP field and push it into this form. I picked up a few 'Shooting Info' threads in the forums, bemoaning the loss of this data too. Why sometimes and not others? It might be your camera model/lens/focus mode, but possibly did you shoot tethered?
Here is a sample of some of the XMP data - as you can see there is a lot of useful shooting information available but not accessible!

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.
