How it Works

Digital cameras embeds a clock and for every photo shot the date and time is saved within the digital picture. Digital pictures are saved using the EXIF standard file format. EXIF provides a DateTime tag that is the date and time of image creation. The format is "YYYY:MM:DD HH:MM:SS" with time shown in 24-hour format, and the date and time separated by one blank character. Since the date and time is recorded within each photos, Namexif reads EXIF data and renames photos by date taken. Similarly, a timestamp is set to each video files that Namexif is able to extract in order to rename the video file.

Why does the name start with the year?

By default, Namexif renames photos starting with the year, then month, day, hour, minute, second. Doing so keeps chronological order right when your file browser displays filenames in alphabetical order.

What if two or more pictures have the same EXIF date?

In case several photos have the same date, Namexif adds a suffix to differentiate filenames with same date. For example, if you have 3 photos taken on August 15th 2019 at 6PM 5mn and 27 seconds:

• 2019-08-15 18.05.27.jpg
• 2019-08-15 18.05.27-1.jpg
• 2019-08-15 18.05.27-2.jpg

What is the shift time by option?

This option allows to adjust time from seconds to hours. This is useful to synchronize multiple cameras or to compensate a jet-lag. The format is +H:MN:SS where H is for Hours, MN is for minutes, SS is for seconds. The sign can be negative. Examples:

• +0:10:00 will add 10 minutes
• +1:00:32 will add 1 hour and 32 seconds
• -0:00:10 will subtract 10 seconds
• -6:00:00 will subtract 6 hours

What is the eight characters format?

In order to burn a CDROM, you may require an ISO 9660 mode 1 file systems where filenames are in UPPER case and up to 8 + 3 characters. For this option, Namexif computes how many seconds elapsed between photo EXIF date and 1/1/1998. This amount of time is then translated into an hexadecimal base, allowing to map date from 1/1/1998 to 1/1/2134.

How to synchronize photos from multiple cameras?

Namexif provides an easy way to make a chronological photo sequence from multiple cameras by renaming files with date and by adjusting (if necessary) any time difference between cameras. See below example.
