Set Date & Time Names

 

A small utility to change the names of photos to the date & time they were taken.

You can download it for OS X.

Instead of having a folder full of jpeg files with names like IMG_0001.jpg, IMG_0002.jpg etc. the names will become more meaningful:  20090210-120533-NI.jpeg 20090210-121009-NI.jpeg and so on, indicating the date and time at which they were taken together with a code for the camera.  ISO format YYYYMMDD-HHMMSS is used, so that they will sort correctly in the Finder.

The program also allows you to correct the time by a number of hours and minutes, in case you changed time zone and forgot to adjust your camera's clock or if your camera's clock just was not set correctly.

The information is taken from the photos themselves, not from the file system.  The panel looks like:

and there is only a very concise "help".

First thing to do is to click the "Add Camera" button.  An "open file" dialog box will pop up, you should navigate to a file with a photo taken with the camera to be added.  The application will find the camera identification in the photo and will propose a two letter code.  This needs to be done only once and is necessary only to distinguish multiple cameras.

Once you have given this identification the application will remember it in a preference file.

From then on you can drag a folder containing photos over the top field.  The middle field will display the original names and the proposed names it will change them to.  You can now still adjust the time by some hours or minutes if necessary.

Clicking the "Change Names" button will change the names of the files and this cannot be undone. However, since the info inside the photos is not touched, you can still redo the change, e.g. should you wish to adjust by a different set of hours and minutes.

At this time (2009-02) there is a bug in that it will sometimes not function properly if there are other than camera files in the folder.  It also sometimes does not correctly recurse over enclosed folders, but no harm is done.  I'll fix these bugs as I have time.
