More and more users are entering the world of photography, especially thanks to the good quality obtained with mobile sensors. What many are unaware of is all the information that those image files hide into what our photographs become. All this information is provided by EXIF, IPTC and XMP that tell us all the content of that image, such as its pixels, shutter speed, aperture among others.
Why is EXIF data in photos important?
This, which seems to be of no importance, can play against security and privacy, since all images have a series of data called EXIF or metadata that includes all the information that the photo contains that we may not be interested in sharing. And it is every time we innocently share an image we are providing EXIF data where all your information is contained .
And it is that among the much information of this type that is attached, you can know our exact physical situation, the software with which we are working, the capture device that we carry, something that should not generate indifference when we decide to share them on the Internet.
Therefore, if we think that publishing an image on the Internet may violate our privacy, it is convenient to know that there are programs and applications that offer us the possibility of reading EXIF data from our photos, as well as editing and deleting them with the push of a button. .
Programs to edit and clean EXIF data and metadata
When it comes to editing and cleaning the EXIF data and metadata of the photos, it is important to have an application that can carry out the work properly. Most of these programs are usually free, so we will not have to pay anything for their use. Some are software explicitly developed to develop this function while others are photo editors that have this possibility among their features.
QuickImageComment, edit all EFIX content
It is a tool that will be in charge of showing us all EFIX, IPTC and XMP properties of our images taken with a digital camera or mobile phone. Similarly, some of this metadata can be edited . It also allows to display other properties such as recording date, modification date and comments. This application allows us to use it to rename batch files and select a fixed and a dynamic textfrom the metadata fields. In addition, we can change both the date and time of the recording of one or more images, as well as add or subtract days, hours, minutes and seconds. Its main disadvantage is that some parts of the program require some knowledge of the image metadata for its correct use.
