Is it possible to batch change time on photos

Hi, I got a question regarding changing the time on photos. I just came back from Australia and have loads of photos from the trip as well as the photos from my friends. However, no one else set the time on the camera to the proper australia time. I got Denmark, German and American time zones. Is there anyway to change the time zone or something on the files so they are nicely in Order is that asking way to much, hope to hear form someone.

Select the pics in the iPhoto Window and go Photos -> Adjust Date and Time

Batch change time only, not dates

I have imported photos from my cell phone and have discovered that the date stamp on all of them is exactly 7 hrs fast, even though the cell phone itself displays the correct time.
How can I change the time by exactly 7 hours on all of these imported photos (of which there are hundreds), other than one at a time? I see with batch change that you have to change to the same date and time on all your selected photos.
Thanks.
Barb

It will work. Select the pics and use the Hour column to add seven hours. The date will only change adding the seven hours will push the photo past midnight.
So, a photo tagged at 7 am on January 1 will be time shifted to 2pm on January 1
A photo tagged at midday in January 3 will be time shifted to 7pm on January 3
A photo tagged at 8 pm on January 4 will be time shifted to 3 am on January 5
Back up before you try this. If it doesn't work, restore your back up.

Is is possible to batch change photos to original date?

I'm amazed at how mixed up my photo lib is (I'd really like it to be chronological) due to edits and other mysteries. Is there a way to batch change a bunch of photos (I have 11,000 - how many should be in a "batch"?) to revert back to original date taken??? Thanks for any help! Donna

Do Not use Shootshifter on photos already in the iPhoto Library. This will rename the files and that will damage your Library. Every file renamed will be lost to iPhoto.
Instead, try an experiment:
Export a few of the files from iPhoto and use Graphic Coverter (you can download a Free Trial) to examine them. See what it tells you is the date of the photo. This will tell us if the problem is with the pic or iPhoto.

Is it possible to batch change multiple file extensions

Is there a way to batch change file extensions? I have more than 150 files on which I need to change the extension and it's a bit of a pain to do each one separately and then have to confirm it.
Thanks!

This is where the terminal can be your friend. Open up terminal and change to the folder in question
To do this, assuming the folder is called 'myfiles' and is on your desktop:
cd ~/Desktop/myfiles
(Or you could type cd then drag the folder to the terminal window to save typing)
Then the command below will rename *.txt to *.rtf (change the two occurrences of 'txt' and the one 'rtf' as appropriate:
for f in *.txt; do base=`basename $f .txt`; mv $f $base.rtf; done

How to batch change in new Photo app

I switched over to the new Photo app. I imported my photos from my iPhone, and then went to batch change the titles (which I use to search for specific pictures and places). I can't find an option anywhere to change anything more than one photo at a time! I uploaded over 200 pictures, I can't make modifications a photo at a time.
Someone help me please!

Batch change the titles in another app before you import the photos into Photos, for example in iPhoto.
Or use keywords instead of titles. You can select multiple photos and assign a keyword to all photos at the same time from the Keyword Manager.

Applescript to batch change "title" in Photos

I'm trying to use the new Photos, but without being able to batch change the title, it's not going to work for me. I saw a script in a previous post that shows how to do this, but I couldn't get it to work - apparently the script only works on small sized photo databases? Mine has about 20,000 photos and 1,700 videos.
Has anyone come up with a solution for this? Photos is pretty much unusable without being able to batch change things like title (primarily) and photo name.
Eric

There are several Applescripts to do what you want. They are listed in the Photos for Mac User Tips.

Batch processing time lapse photos

I have a series of several hundred photos taken one a day. There is some day-to-day variation in the camera position which causes distracting jitter when run through a simple time lapse engine. There are a couple salient landmarks in each photo which could be used to auto-rotate, and (possibly auto-scale) the images if the software could be directed to recognize and align these simple features.
Thanks

There are few forums dedicated specifically to time-lapse. Try to search for timescapes.com, but it might have changed names.
Many of those artists and technicians use conventional After Effects filters or purchase special batch processing scripts for Photoshop. The scripts or filters level out those slight mechanical variations in f-stop on every frame and can help smooth out color tone issues. The output is usually converted to tiff or jpg for ease of animation and renumbered for ease of importing the sequences . Then they'll run AE's stabilizer.
Those forums also included lots of tutorials or advice on how to tweak your gear to shoot better source images that require less post production processing.
Good luck, hope you find something useful out there.

Changing time of photos

Is there a way to automatically change the date in the EXIF to 2 hours before? I came down to Maui and didn't change the time on the camera, and I have about 300 photos from the last couple days that I want to change the time on the photos to 2 hours prior. Anyway of automating this?
Thanks

Got it fixed with PhotoInfo.

How to batch change a date in aperture

Is it possible to batch change a date in aperture the way I do it in iphoto (command option B)? I dont want relative dates, I want a group of scanned pictures (negatives) to have the same date, but separated by one second.

Dale,
Aperture does not support this. I wrote a little Apple Script to adjust the data and time like iPhoto and posted it on my web page. You may have a look and take this as a starting point. I wrote the script last year; so it has only been tested with Aperture 3.2.4 and Lion, not with the current version: The script is here: Adjust Date and Time in fixed increments
But no guarantees given for the current Aperture version 3.4.3.

Batch change dates - question?

Can batch change (or some other app) change the date of the first pic in an event and then simply adjust ALL other pic dates by the 'change delta' you adjusted the first pic by? I just did a batch change and every pic in the event now has same date/time although the event spans several days. Seems like a 'no brainer' to me for a computer to apply this same delta to all pics - but I'm not a computer guy. Thanks in advance!

Yes what you want is adjust date and time - just above batch change in the photos menu -- select a group of photos and the entire group will be adjusted by the delta of the first one
You have the option of modifying the original which I usually recommend
Since you have already changed the dates and times on some of the photos you want to adjust you may need to go back to a backup of them prior to having their information changed - depends on if you modified the originals or not

Batch Change - start title number later

I really like using the Batch Change feature to change the title of a group of photos to "Trip 01 - " etc. and in the past this has been a great way to put "Trip" (or whatever word) in the title and then have a different number for each photo prior to adding details. But, currently I am halfway through a trip and have imported many photos, and realized that when I take more pictures and import them later on I do not know how to batch change them to restart the numbering. For example, let's say I have 200 photos. The first 200 will come out as "Trip 001", "Trip 002" ... "Trip 200" but then when I import more photos and do batch change the new photos will be renamed starting with "Trip 001" whereas I want them to start at "Trip 201" to continue the prior set of numbers. Is there any way to accomplish this?
The reason I would like to start the numbering from a later number rather than redoing all of them is that following the number I add details. It is not just "Trip 001" but rather "Trip 001 - building x" and if I were to renumber all of them then I would lose the details of the titles that I had already edited.
Any ideas on doing this would be most welcome! Thanks

In the View menu select Titles as one of the entities to display under the thumbnail. That should display the new titles. The Info window only shows the file name. Changing the title does not change the file name. To get the file name changed you'll have to export the files with the option to use the title as the file name selected.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto 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), 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 08 libraries 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.

Batch Change Photos' Date - Not Time

Is there a way to change a bunch of photos' date, but not the time?

Neil:
Not in iPhoto. Unfortunately you've go to change the time as well. If there are not too many of them you can do it this way.
1 - move all that you want to redate to the same date to a new roll.
2 - in the Finder copy the folder in the Original folder that represents the roll with the files to be redated to the desktop.
3 - using an application like PhotoInfo batch change the date to whatever you need. It can just add or subtract a specific number of days, months or years to the date as you see fit.
4 - change the name of the folder and import back into iPhoto.
5 - delete the original roll of photos with the incorrect date.
That's about it. It's not too convoluted and can be done. This way the new date will be embedded in the file and stay with it if needed in a new library or other application.
Do you Twango?

Batch-change date (time)...

I know you can batch-change the date in iPhoto, and there's the option to add X seconds between each photo, but what I need to do is change the time by XX seconds/hours. Basically, this weekend we had two camera shooting a trip we were on. I thought both cameras were synched (clocks) but one camera was off by 12 hours (it was on AM when should have been PM). So, I need to add 12 hours to each photo for the 1 camera. Is there any way to do this via a batch (ie. not manually going through each of the 150+ photos and setting the time) so when I make an album of shots from both camera, sort by date/time, they synch up.
If there's no way to do this in iPhoto, could anyone suggest another application that could do this before importing into iPhoto?
Thanks,
Kristin.

Rather than start a new topic, I'm going to just refer to this one since it's recent and exactly the issue I was trying to solve. My situation is that I bought a new camera in January and still had 2006 on my mind, so all the pictures I've taken this year are off by a year. I used PhotoInfo to change the EXIF data folder by folder in my iPhoto Library folder (by this I mean I had to batch change every folder in Originals/2007 and Modified/2007). 2 folders didn't take the changes, but that's another issue for a different forum.
Most of my pictures now have the correct EXIF data, however iPhoto doesn't show the correct info when I select the menu item Photos>Get Iinfo. Doing some searches here says that the only way to update iPhoto is to reimport the photos with the new EXIF data. My question is how do I do that without screwing everything up? I have originals and modified versions of files that are affected. How do I bring them back in such that if I use the Revert to Original command in the contextual menu that the modified files are still correctly linked to the originals?
A secondary question is whether iPhoto is really the program I want to use. Most of my major changes I make using Photoshop. Recently after making changes in Photoshop as well as a few minor tweaks in iPhoto (I don't remember which order) when I tried to revert to the original it no longer existed. It reverted to a modified file (modified in PS or iPhoto, don't remember which). Since then I've been making a duplicate in iPhoto and then modify that one in PS as well as iPhoto. However, after making modifications in PS I have to save it as a JPG in order to keep it organized with all my photos in iPhoto. It would be nice to keep a PSD copy filed along side it. Should I be using something else besides iPhoto that handles EXIF information and changes seemlessly as well as JPG and PSD (and probably RAW in the future)?
Thanks in advance for any info/tips.

IPhoto Batch Date/Time change Suggestion

I recently traveled overseas with my family to a time zone that was +4:30 from my current location. During our trip I took 800+ photographs from my digital camera, 60+ from my iPhone and lots of video from my camcorder. It didn't occur to me until I got back home that not only did I not set the digital and camcorder to the local time where I was vacationing but also my digital camera had somehow been set 2-days back but with the correct home time. So it was actually 2days 4hours and 30minutes behind the time that it should have been. My iPhone photographs were fine because I set it to the local time as soon as I landed there.
Once I synced my camera & phone photographs I realized my problem as my entire vacation was in a jumbled mess. So then I went through the photographs and split the digital camera and iPhone photographs into 2 albums which was not too hard. Thereafter, I went through the digital camera photographs and adjusted the date/time stamp. Some of them I could do in batches, which is not very easy as you need to look at the current date/time stamp, then select the photographs you want to change and then do the math before making the change. The most of it I had to do individually to make sure they wouldn't get jumbled with the iPhone photographs I had taken. So to say the least, to adjust 800+ photographs took a long time and a lot of effort.
My suggestion is a simple batch change like what is available already, but with the option to advance or regress the date/time stamp letting the system use the current date/time stamp.

That command is the adjust time/date command - not the batch change command
Adjust T/D takes a group of selected photos and applies a constant delta to them thereby correcting for camera setting errors or time zone issues
Also note that this is a user to user support forum not a path to Apple - it is a great plce for questions about how iPhoto works - it is an extremely poor place to make requests for changes since there is no one here who can do that.

Batch change of times in iPhoto 6 ?

Is there an easy way to adjust the time of a batch of photos (say, all photos +2 hours). I had taken photos in another time zone but forgot to change the camera's time.
I could not do this batch change in iPhoto 5, so I was hoping for it in iPhoto 6... is it there?
PowerBook G4 15", 1.67GHz (machine model: PowerBook5,6) Mac OS X (10.4.6)

I agree. Camera with the wrong time is such a common mistake that a built-in batch adjustment will be a boost in iPhoto's usability. Doing export, adjust, reimport is a solution, but not very user friendly.
User who tries to combine photos of the same event from several cameras from their friends would find rightaway that most people don't set their clock correctly, or some clocks may drift a few minutes enough to screw up the sequence of a slideshow.
The current iPhoto batch time change is quite useless. Is Apple taking notes?
