The shifting feature can be very useful if, as has happened to you, your pictures are all suddenly marked 2009, even though they were taken in 2012. The example above just sets a particular value for the date and times of the pictures if you wanted to just shift them all by a certain time index, such as the three years forward, you could use: exiftool -AllDates+='3:0:0 0' *.jpg This example changes both date and time: exiftool -AllDates='2012:03:14 12:25:00' *.jpg As with jhead, you can decide to change time and date, or just date. The date and time shifting options, and which formats can be used are quite extensive, as detailed here in this useful pdf. There is a graphical frontend for exiftool in development, but it is in the early stages at the moment, but looks promising. This utility has more options than jhead and is very comprehensive, as noted at the official site. Look at the exif readout from your pictures to get the correct model number. You could also do it just for one some pictures taken with a particular camera if you specified, for example, -model 'D70', but that option must come first in the processing, and must be something like 'D70', 'S100' and not 'Nikon D70'. If you just wanted to change the date without specifying the time, you would use instead: jhead -ds2012:10:29 *.jpg The -ts switch allows you to specify the date and time required and write it to the exif header all in one go: the format specified here is YYYY:MM:DD-HH:MM:SS. To change the time and date EXIF data on a number of files 'in a single click', you could open terminal and do cd to the folder with the pictures and run: jhead -ts2012:10:29-10:28:03 *.jpg With both of these tools you can operate upon multiple files at once, but you may want to back your files up before you start manipulating the exif data. As you already have a GUI solution, I thought I would mention that there are also several ways of changing EXIF data on the command-line two useful tools are exiftool and jhead, which can be installed with this command: sudo apt-get install libimage-exiftool-perl jhead
