Back in the times when people used film camera, they were in the habit of writing on the back of developed photographs. They used to write time, date, location and the event when that photograph was taken. But now in the digital age, all of this is taken care of by the digital camera itself. When you use your digital camera to snap a picture, the camera saves the picture as a file on the memory card and also adds some metadata with the image file. This metadata can be of many different types such as EXIF, IPTC and XMP. Most popular of these metadata types is EXIF which stores the time, GPS coordinates, camera model and many other things in the image files.
Using a freeware program QuickImageComment, you can edit all these three types of metadata with much ease. Not only it allows you to add, remove and modify the metadata from a single image files, but it can also edit metadata from multiple images simultaneously.
Using QuickImageComment is very easy. The user interface of this program has folders displayed on the left side from where you can select the folder that contains your images. For smartphones and digital cameras or the memory cards used in them, it is usually the DCIM folder. After selecting one or more images from the displayed list, you view and edit the metadata from the right-side of the interface. You can view and change the metadata for all the images in a similar fashion.
Since all the images captured with a specific camera at a particular time have a similar EXIF metadata, you can use this metadata information to rename all of those files with a specific filename pattern. QuickImageComment can help you rename all of the images using the EXIF, IPTC and XMP properties. It can even compare the images using this information.
