![]() It can be useful to make a copy of the image first, if you want to preserve the GPS data on the original. Once that's done, I'd save the file and it wouldn't have location information anymore. Then here at the bottom, there's an option to remove location info. On a Mac, I can remove geodata from photos using the built-in preview app, opening a photo, and then opening the information palette, with Cmd + I, I can navigate to the information area and find the GPS tab. Scrolling down further, I can also see that the GPS information was completely removed from this copy of the file. I'll scroll down to the camera section, and I can see that the camera maker and model, along with some other information, was removed from the file. I'll take a look at its properties, and we can compare with the original file. Here's the copy with the sensitive information removed. I'll choose the first option and click OK. I'll click it, and here I have the option to create a copy removing all information, or to remove particular pieces of information. Here I can see the file's metadata, and down at the bottom of this window, there's a link to remove the information. I can remove sensitive information from the metadata of a file here in Windows by opening up the properties for a file, and going to details. To avoid that situation, we can protect our sensitive information by removing it from metadata. Unless the people running the contest removed personal data from the image, depending on how the judging and gallery website worked, the metadata might be there for anyone viewing the image to discover. For example, imagine that I entered my photo into an online photo contest. But because metadata is part of the file, it goes along wherever the file is sent, and that may not be what I want. The photo management software can use the data to automatically classify this photo into an album for San Diego, or for 2019, or for those taken with the back camera of a smartphone of a particular model. ![]() For our personal use, this metadata is really useful. All this information, the location, the camera details, and so on are stored within this image file. But if I had taken the photo at my house, or at someone else's house, or at a sensitive work site, or something like that, you can see how easily that information could be shared unintentionally, and it could be the case that sharing the combination of my location and the time and date might reveal something too, like that I was attending a particular event, or was in the proximity of a certain person, or that I wasn't at some other location at that particular time. Lots of people go to the park and take pictures of flowers. That's a public place, and so, sharing that information, even the precise coordinates that put me at the botanic garden, doesn't say anything really private about me by itself. This photo, for example, I took at Balboa Park, in San Diego. ![]() Scrolling down further, I can see precisely where the photo was taken. There's some details about the photo, and I can see that it was taken with my iPhone XS. And here in the sidebar, I can see that this photo was taken on April 27th, 2019, at 11:15 a.m. I can click the three dots here in the top right of the window, and choose to view file info, to find out more information about it. Here on Windows, I can open the file on the photos app to view it. As an example here, let's take a look at this photo that I took a little while ago. ![]() Metadata holds information that's useful to us when we work with the files, but if we intend to share a file with others, we may not want them to have that metadata. Videos and photos often include information about what camera was used to create the media, what color profile the file uses, and they frequently include other information, like a physical or geographic location, and other tags for various purposes. Many files, especially media files like video, audio, and photos include huge amounts of metadata. Metadata can include information like when a file was created or updated, who took a photo, who created a document, and more. Metadata, or data about data, is an important part of files.
