I have a large quantity of photos from different cameras that did not have the time set correctly and so need to use a time shift function across multiple files. DOpus help comes up with "The Date digitized and Date taken metadata Picture fields let you enter what's known as a time shift string, which lets you perform relative changes to the existing values of these fields" which seems to be exactly what I want. However when I go into "edit metadata" the entry window for date / time only allows input of absolute figures for hh:mm:ss. I have tried selecting multiple files with different times and setting the desired time for the first file in case this establishes a time difference to apply, however all files then change the date to that exact time. How do I enter the "time shift string" referred to?
Click where it says Select Operation... and then type in the time shift string.
For example, to add 1 hour to the first time:
Thanks, couldn't see for looking! Works a treat.
