Modify EXIF date?

iPhoto '11 (9.2.2) lets me set a date for photos, but apparently this new date is known only to iPhoto. Even if I check the "Modify original files" box when I set the date, the original date of the photo in its EXIF data is unchanged. This can be a problem, as when exporting photos or uploading photos to Flickr, which either can't see or ignores the date set by iPhoto and uses the date in the EXIF data instead. Is there a way to change the date in the EXIF data?
I saw one post (from 2007) that said checking the "Modify original files" option WOULD change the EXIF date and another post that described changing individual photo dates through the Info mode. Neither works for me. Is that a bug? I have to use Batch Change to modify the date for even a single photo, and even if I do that with "Modify original files" checked, the EXIF data is not changed.

Sorry if I'm not being clear. Here's a summary:
1. A photo is taken in August of 1966 and developed as a slide.
2. Last summer the slide is digitized: EXIF date is 6/7/11.
3. A month or so later I add the photo to iPhoto, which still reports the date as 6/7/11.
4. On 3/7/12, I edit the photo in iPhoto and use the Batch Change feature to set the date to when the photo was actually taken: 8/1/66. As expected, iPhoto Info now shows the date as 8/1/66.
5. On 3/12/12 I use the Flickr uploader in iPhoto to upload the photo to my Flickr set. Flickr reports the date of the photo as 6/7/11.
6. Today, 3/21/12, I look at the file information for the photo in two places: Finder and Tools Inspector in Preview. Both of these places report the same Created and Modified date: 3/7/12 (the date I edited the photo in iPhoto).
So, what is unexplained is:
1. When I change the date in iPhoto, why does the file creation date and modification date change to the present day instead of the date I set?
2. When I upload the photo to Flickr, why does the creation date revert to the date when the image was first digitized from the slide?
And, of course, my only goal is that the date I set in iPhoto show up in Flickr when I upload it there.

Does Adjust Date & Time Modify EXIF data?

If I use the adjust date and time does it modify the exif data in the original photo, so if I export the photos elsewhere it will preserve these edits? I was using Picasa and fixed the date and time on a few photos only to find them back to 1/1/2002 when I imported my photos to iPhoto

I just saw this checkbox today and hoped it meant that. I've really wanted this feature for a long time now.

Batch Change "Date Modified" to match Exif Data After iPhoto Export

Among several other posts about similar situations, I have found none that directly and simply resolve this issue.
My wife imported a bunch of photos into iPhoto directly, but I wanted them in a folder on the hard drive.
I pulled them out of iPhoto into a folder, then deleted the ones in iPhoto so that I could sort them and reimport.
I then realized that the photos all now showed the date they were imported into iPhoto as their created/modified dates, which makes it impossible to easily sort them by the date of the pictures.
I checked the Exif data, and it has preserved the correct creation date event though checking "info" on the pictures shows create date the same as modified the same as iPhoto import.
Is there an easy way to batch change an entire folder of pictures to change the Created/Modified dates to match the Created date from the Exif data?
The only other similar posts had answers that reccomend a piece of software that does not seem to actually do this, and one that suggests some sort of confusing script that I don't really understand.
Please help - I have a bunch of family photos that I really need to fix.

shootShifter helps to redate and rename complete folders of images based on the EXIF data or Finder dates.
So it will do batches.
I also believe that exporting the Original (File -> Export: Kind Original) will make all of this unnecessary.
I don't like having them only in iPhoto so I organize the originals into folders by choronological event then import them so I have copies outside the iPhoto library to put elsewhere.
You understand that you're using twice the disk space there, right? And that it's quite unnecessary. All iPhoto does is to put them in folders too. Have you looked inside the iPhoto Library ever?
Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed. Your photos are in the Masters folder.
Standard warning: Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things,, deleting them or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.

Modify "date modified" on images to match "EXIF date"?

heya,
This isn't strictly a Arch Linux related question, but the community on here is fairly knowledgeable, and it's a scripting question .
I have a bunch of images in a directory, taken by my old BB 9700 phone.
The names of these are a bit mixed up, because BB's tend to randomly reset the increment counter - the files are named something like "IMG00001-20100216-1319", but I've got "IMG00001-20100418-1220", for example, as well.
When I browse these with Dolphin (KDE File Manager), I can choose to sort them by name, or by date. However, this is date modified, not the EXIF date. On Windows, Explorer lets you sort either by Date Modified, or by "Date Taken", which I assume is the EXIF date.
It's a bit annoying that Dolphin doesn't let you sort by EXIF date, but that's another issue. On my phone (Nexus One), the Android Gallery application also seems to sort by Date Modified, not the EXIF date.
My question is, is there any way to say, run "touch" on the files, and get the date modified to match the EXIF date? Any programs or scripts you know of that can do this?
Cheers,
Victor

Well... you can write a quick 'n dirty script in you favorite language for example zsh+python+awk
$ for i in *.jpg; do touch -d "$(identify -verbose $i|awk '/exif:DateTimeOriginal:/ {print $2,$3}'|python -c 'from time import *;from sys import stdin; print strftime("%Y-%m-%d %H:%M:%S", strptime(stdin.read(), "%Y:%m:%d %H:%M:%S\n"))')" $i;done
(This works on bash+python+awk too, I think). This works for me because my photos have a exif filed with 'DateTimeOriginal' run identify -verbose in your images and select the correct field. My exif field have a format '%Y:%m:%d %H:%M:%S' if this is not your case change this.
EDIT For this simple date format case you can use only awk
for i in *.jpg; do touch -d "$(identify -verbose $i|awk '/exif:DateTimeOriginal:/ {print $2,$3}'|awk -F : '{printf("%s-%s-%s:%s:%s", $1,$2,$3,$4,$5)}')" $i;done

Problems with InDesign CS5 reading EXIF data

Hi there - my first post. Been searching all over for a solution but no one else seems to have this problem.
I'm trying to create a picture book using InDesign and have JPEG's loaded in direct from many cameras (HTC, Canon etc.)
I'm creating captions using either Live Caption or manually to show the description and exposure details.
InDesign can always read the caption and tags (if it's been set by Picasa in the IPTC tag) but it never shows the EXIF camera details - it just shows <No data from link>. In the links section if you right click on the image and open XMP File Info you can see all the EXIF info is there.
Even dragging images from Bridge does not help.
The only way I can make InDesign read them is to get Adobe Bridge to modify the image by completing a random IPTC field. Bridge won't let you modify EXIF, so presumably that does not get changed, so why that helps I do not know.
Is there any way to get InDesign to read EXIF's first off?
Thanks, Simon

It's been a long time since I looked at this. While I was able to solve the problem using EXIFTOOL to process that JPEG files (and write XMP) I decided against including the metadata into the InDesign book as it would mean processing all my images, and having to remember to process any new photos I take. Book is behind schedule so I cut it all out.
I changed the code that was submitted by John, and made the following .bat file that sits in the same folder as EXIFTOOL. The .bat files contains:
%0\..\exiftool.exe -overwrite_original -TagsFromFile %* -@ exif2xmp.args %*
pause
In order for this to work, you need the exif2xmp.args file. I didn't know where it was supposed to be located but put it in the same dir as EXIFTOOL and the bat file above and it worked. I got the file somewhere from the EXIFTOOL website - think its in the full archive that they provide.
To use it, you can drag multiple files onto the .bat file in Windows and they are processed. N.B. this overwrites the original photos, so make a backup if you are unsure.

Incorrect EXIF date

Last night, I closed Aperture and went to bed. Everything was fine. This morning, I woke up and saw that a picture had gotten out of order when sorting by date.
http://www.peejstudio.com/temp/aperture.jpg
As you can see from the screenshot, magically, Aperture has decided a new EXIF date for my picture. Why?

Hi Lee Jay, thanks for the quick reply.
So it is just the display of dates that is wrong, it hasn't actually modified the EXIF data in my RAW file?

Sort by EXIF Date/Time

Would be nice to be able to srt by EXIF Date Time Original or EXIF Date Time Digitized. The existing file based Date Time Create or Date Time Modified may not be accurate. Some of our events (like a wedding) have photographs taken from a number of photographers and some of those files have been copied at some point before getting to editing, so the file Date Time Created is no longer correct. The file Date Time Modified sometimes works for us, but may not be reliable either. Right now we have a program that copies the file Date Time Modifies to the file Date Time Created, which usually works ok. Using the EXIF data would let us sort all of the aggregated shots by their original create date so that they are in the proper shoot sequence, without having to deal with all of this.

Does anyone know how to sort files in bridge( or any other program0by time created?

Missing/Corrupt EXIF Data

I was looking at a folder of images today, and noticed that the camera data was not showing up and the images looked out of focus. Moments later the camera data showed up but the images still looked blurry (thumbs). Suddenly all the thumbs in the folder disappeared, being replaced by the .nef icon. I mean instantly, they all changed to the icon. I tried to open but got the message:
"Could not complete the request because it is not the right kind of document. "
So I tried to open it using DXO and it returned :
"This image cannot be processed since its EXIF data cannot be read or is missing".
Right click the image and the File Info is missing from the menu.
How does this happen? I have opened these images in the past. I can imagine the instant insanity should all my .nef's suddenly do this!
I am using Bridge running Photoshop CC on Win 7 64 bit. The .xmp data exists according to Win Explorer. There is no Bridge cache showing for the folder in Win explorer.
I am unsure as to whether this belongs here or in Bridge or???

I don’t think WFW would know about any outsider accessing the file on dropbox since it runs on your local computer. If this is the first time you’ve used dropbox, it may have been asking for permission for dropbox to access your local system via the public network (there are local, domain and public tiers in the firewall rules) since dropbox synchronizes things between computers via the data stored in the dropbox cloud storage.
In other words, I downloaded the file to my local computer using the public link you provided, and wasn’t logged in as you, so would have been accessing the dropbox cloud for retrieve the file but not be logged in as you, but I don’t think the WFW would know I was doing anything for that interaction because that is between me and the cloud, not something on your local computer. Depending on how you answered the WFW question, you may have blocked dropbox from doing its normal things. You can get into the WFW configuration in Admin Tools (or maybe Control Panel) and enable things for a particular program that you may have disabled by mistake.
Back to the corrupted file issue: spot-check a few of the bad files on the backup, right-click Properties, and look at the Created Date and Modified Date, compared to the expected date the backup first would have copied them, to see if either indicates the date the zeros were written. You might want to compare those dates on files that are ok, to see if there is some difference in pattern. It is possible the backup software updates those dates to be what the source files dates are which might mask the backup-software's last-copy date, which is what you want.
If you can determine the date for the zeros and it is fairly recent, then the system event log might list something as having occurred.
If there haven't been any viruses, then I'd say it was a transient condition, either in the circuit-boards or cabling or the hard-drive media, itself.
Has the computer ever locked up so you had to turn the power off to get control back of the mouse?
You can test the hard-drive media for errors by chkdsk d: /r or chkdsk d: /b (or the gui-scandisk equivalents) to scan for data errors--iffy media problems. Move any virtual-memory swapfile off that drive if you want to test it while the computer is running. Maybe do a plain chkdsk, first, one where you don't fix problems and don't test the media, which would find problems indicated with zeros in the directory-structure, first. And if you find any of those, disconnect your backup drive in case the "fixes" corrupt even more things and that gets replicated.
A chkdsk that fixes media problems will likely take several/many hours.

PSE 10 editor changing date taken in EXIF data

Hello. I have just joined the forum after recently buying PSE 10 Editor for Mac. I had no trouble at first but now after I have saved an edit I find that the date taken has been changed to the same as the date modified & imported.
I can change it back manually through iPhotos menu but this is a bit of a nuisance when a lot of photos are involved, I don't know why it has happened but how do I reset it to give the correct date ?

I hate to be the bearer of bad news, but it didn't help. I lost another photo today and had to retrieve it
for the Organizer from my Windows files. Instead of placing it next to the original photo (or in the same area), it placed it in a file called Adobe/Photoshop.com. I made sure again that the line you referred to isn't checked. In addition, when the photo doesn't get lost, the Exif date for the photo does get lost and the photo is dated today. These two problems seem to be connected, although I can never predict which one will occur. Anybody have more ideas? Could it be a Windows 7 issue rather than a Photoshop issue?

EXIF data corrupt

When I modify a picture with Adobe Photoshop Elements 10 it very often (but interestingly not always) happens, that afterwards the EXIF data are mostly lost. In Picasa I than only find a remaining block of about 5 values. Photo Me tells me, that "The EXIF data header of the chosen File is invalid", my smart TV is not able to view the picture any more. Even Microsoft Phot Gallery refuses to open the file.
When I open the corrupt file with CEWE foto viewer and restore it afterwards, the values are back again. But unfortunately the size of the file gets trasticly reduced.
Since this is not a general problem, I don't know where to look for a solution. Obviously it's not the program settings, since I haven't changed anything there.
My camera is a Pentax K5, But I don't think that there is a problem, because the original pictures are always ok.
Who knows more?

I may be wrong but it appears that all Adobe products strip out the camera maker notes data from EXIF Metadata.
Since EXIFtool and several other applications can properly read and write to and from the EXIF maker note area, I can only assume Adobe does not care about preserving this information. I've been researching this topic for the past few days and it appears Adobe has known about the issue for several years but has never fixed it. Since they have not fixed it, I can only assume they don't feel it is important enough to us users. Some folks keep their original files and do not let any applications ever edit them in any way, including metadata. That wouldn't be a problem if we didn't have 10's of thousands of images to deal with. Originals, edited ones, backups, etc.... It starts to chew up space pretty fast but keeping your originals protected from ANY updates is the only way to ensure the maker notes stay in tact. Of course this makes it really inconvenient to quickly look at the maker note of a particular photo. This camera specific information can be used to help the photographer learn how he/she can reproduce a certain photo characteristic that they may really like. Once again EXIFtool and several other software vendors have figured out how to read/write to the metadata without destroying it.

When exporting a photo to photo library, all EXIF data is lost. What rational is behind this?

When exporting a photo to photo library, all EXIF data is lost.
What rational is behind this?

Thanks for your reply on this!
One issue seems to be with Foto Library app itself. When running an auto-correct there it looks like EXIF will be stripped more or less completely.
Second issue is in iPhoto app on iOS when working on RAW. When exporting to the roll the EXIF is modified in a way. It was keeping most of the EXIF in case of Canon 5D MKII that I tested today, but the EXIF data is definately changed, e.g. lens type is different because maybe some fields are ignored there. Also the images are silently scaled down by 50% which is kind of annoying.
The initial problem was observed with a Pentax K7 and I will need to reproduce the issue in this config I assume. Maybe tomorrow I can do this.

.mov exif data problem - Time is off by hours

I have the same problem that SD_Christina posted 2010:
"I import my photos and videos taken on my iPhone using "Image Capture", then I sort them using Adobe Bridge CS5.
When I take a video (.mov file), the exif data shows the "Date Created" at 7 hours ahead of "Date File Modified". (ie: Date Created: 7pm, Date File Modified: 12pm)
The problem is - the correct time (that the quicktime movie was taken) is the "Date File Modified" time. So, if I should choose to rename that file...of course the "Date File Modified" time is changed.
Additionally, if I choose to rename all of my files (which I do) using the Date Created - the movies can be given the incorrect name. While sometimes this is not a problem (after all....12pm and 7pm ARE in the same day) if I create a video after 6pm, the "Date Created" ends up in tomorrow....follow?
Just about everything I've found on the internet says that videos don't have exif data....which is just silly....cause I'm looking at it and sorting my files by it...so....something is there!
On the other hand, if I could just CHANGE the exif data...I'd even be willing to do that...but I can't seem to find a MAC based exif changer for .mov files. "
With my iPhone 5 (iOS 7.1.2) the JPG times are always OK. But SOME MOV files have it +3hours off in my timezone.
I rename my JPGs and MOVs via Graphic Converter as YYYY-MMDD-hhmm-ss.mov according to their EXIF. Usually this works OK but I have to watch out those random MOV files that are +3hours off and rename them based on their creation date which is correct (that time might be the start/end of the clip while EXIF is the opposite but I digress...).
I have not yet seen any pattern or workflow that might cause the MOV EXIF to be incorrect. Anyone?
And is there a tool that can edit the EXIF and location data in MOV files? Graphic Converter can edit those only in JPGs. (The location data is sometimes incorrect in MOVs taken with my iPad mini whch lacks GPS and obviously didn't get correct location via the tethered iPhone -- I guess I should try to enable Bluetooth in both devices because that seems to give the location to the iPad(?).

Hi,
I'm having a similar problem, which I've been able to easily reproduce. It may be related, but I don't have a fix for it.
I live in Oslo, and just got back from a trip to Mumbai (which is 4.5 hours ahead of Oslo time). When I arrived in Mumbai, I used the Time Zone function on the phone to set the local time. When I got home, I imported photos and video into iPhoto and found that the photos I took on my phone in Mumbai showed the correct time and date, but the videos I took on the trip had a creation date listed in iPhoto that was equal to Oslo time (4.5 hours different from the photos) and not Mumbai time.
It almost seems like the camera app saves the photos based on the iPhones current Time Zone setting, but saves video with a creation date equal to the time zone the phone was originally set to.
I've been able to reproduce the bug a couple of times. The only fix I have for it is manually changing the time and date of the videos in iPhoto.
Could someone else try this out and see if they can reproduce the problem as well?

Change date modified to date taken?

I have always thought that it was crazy that the EXIF data for my digital pictures can get changed in Windows/Adobe from date taken to date modified. I have mentioned it in these forums before but never got a satisfactory answer.
I looked at the problem again & find that other have the same problem & that there appears to be a solution. I find on the net a small utility called. 'JPGDateChanger'. Before I tried it I thought that I should ask has anyone used this program & did it work correctly for them? If the change that would appear in Windows explorer have the same result in PSE 11,or does it create problems with the catalog?
If at all possible I would prefer to get this done within PSE 11. Is there any way to achieve it & if not why not?

The organizer that ships with the PRE Elements + PS elements 12 Combo pack uses the file systems Date Modified for organizing (win 8.1 64bit) . It does not use the Date Taken from the EXIF data.
This can be easily confirmed using Windows explorer. If you sort in Explorer by modified date, that is exactly the order the files appear in Organizer. If you add the Date Taken (by right clicking the column headers and adding the column) you can see the EXIF date taken field. The organizer ignores this filed in favor of Date Modified.
The workaround is to use the little JPGchanger application referenced here to set the date modified to the date taken field. This tool was specifically written to fix this issue.
The other proposed work around's involved renaming files to include date taken in the file name itself during import. Not only is that clumsy, but I have already have 10,000+ pics on my computer that aren't named that way.
My two Cameras are a Canon S90 and an ESO 550D. I also have pictures from Google Nexus5 and Samsung Galaxy phones to deal with. Not having the EXIF Date Taken field used is a MAJOR pain!

Can exif data be changed in photoshop

I am engaged in a nasty lawsuit and now I have a question. So I hope you can help me further.I have a question about adobe Photoshop CS2.
I have added in the annex 2 pictures of properties of a photo. The photo is on 1-10-2010. All the exif data from the camera stand in it too (see CANON EOS 350 d still camera data). Now my question, if you the picture edited in Adobe Photoshop CS2 can then also the date of recording of the photo? I.e. this date change? Continue then the exif data exist, or disappear than the camera data if one adjusts this date in Adobe Photoshop and you only see the "updated" date taken. I have always understood, that if one changes, the date of recording the exif camera data disappear from the picture. In this case, the exposure time, the camaramodel etc.. I understand that you have a create date (exif) original (recorded)
to illustrate the RAW data of the photo:
<exif:DateTimeOriginal>2010-10-01T11:39:18</exif:DateTimeOriginal>
<exif:DateTimeDigitized>2010-10-01T11:39:18</exif:DateTimeDigitized>
and a create date and modify date (date of operation) in photoshop.
To illustrate the RAW data from the same photo:
<xmp:ModifyDate>2010-11-30T20:09:55+01:00</xmp:ModifyDate>
<xmp:CreateDate>2010-10-02T20:29:54+02:00</xmp:CreateDate>
<xmp:MetadataDate>2010-11-30T20:09:55+01:00</xmp:MetadataDate>
<xmp:CreatorTool>Adobe Photoshop CS2 Windows</xmp:CreatorTool>
In this case are the exif data for the original date of recording of the camera and are the xmp data for the dates of editing in Photoshop?
Can anyone confirm this, or is it different story. In advance, thank you very much for the effort, I would very much benefit from

Thanks, where can I find these 3 dates, when looking at the photo (picture). Because above I have an </exif:DateTimeOriginal>2010-10-01T11:39:18 and then I have a
<xmp:ModifyDate>2010-11-30T20:09:55+01:00</xmp:ModifyDate>
<xmp:CreateDate>2010-10-02T20:29:54+02:00</xmp:CreateDate>
Are these the 3 dates you meant?
