Thanks for the response. If you're right, I'm surprised. Here's what the published intro says about the program:
- Rename photos using EXIF meta data (i.e. "Date Picture Taken", "Resolution" and other information embedded in all JPG photo files) Rename your holiday pictures from a meaningless dsc1790.jpg to NewYork1.jpg in a flash.
- Change files' creation and modification time stamps.
And here's what the Help has to say about Autodate.
Auto Date - Add various dates to the filename, in various formats
This allows you to prefix or suffix the filename with a variety of dates - the date that the file was created, modified, or accessed, and also with the current date. Useful for pictures! The date can be added in 9 different formats, some of which also include the modification time. You can also specify the characters you would like placed between the date/time and the existing filename (the Sep field) and the character to place between the different date/time segments (the Seg field). e.g. a format of DMY, with a Seg field of "-" would give a date of (for example) "25-01-03". The "Cent." flag is used to indicate whether or not you would the year to be represented with two digits or 4 digits
You also have the option to specify your own custom date formats, and these are detailed here.
If you are also updating the file's Creation-date or Modified-date, then you can also choose the "Create (New)" and "Modified (New)" values, and these will equate to your new timestamps.
One of the dates you can use is "data taken". This is an EXIF flag which is often embedded in JPEG images which were created using a digital camera. The software will only get the flags from JPEG images (.JPG or .JPEG extension), not TIFFs. If no date is available then no date will be used. So for example, choosing to append the Date Taken for a .EXE file will simply append nothing.
The clear implication is that one can change the "date taken" for JPG files. There are also a significant number of posts regarding sophisticated use of the EXIF data. So, I'd like to hear a further confirmation that this impossible in BRU. Thanks.
