Before the invention of digital cameras, and in the old days of film, photographers, for learning purposes and for understanding what they might do wrong when an image didn’t come out right, they use a pen and a notepad to record important information such as shutter speed, aperture, and date. It was a very painful process, especially for newbies.
Nowadays, every modern digital camera has the capability to record this information, along with many other camera settings, right into the photo file and these data are called metadata or EXIF. These settings can then be later used to organize photographs, perform searches and provide vital information to photographers about the way a particular photograph was captured. Being able to read such data can be of great importance not only for beginners but also for other photographers who want to find out what settings and tools were used to create a particular photograph.
This stored data is called “EXIF Data” and it is comprised of a range of settings such as ISO speed, shutter speed, aperture, white balance, camera model and make, date and time, lens type, focal length and much more.
What is EXIF data?
EXIF stands for “exchangeable image file format”, it allows you to store certain information in your photos. This information is known as “metadata” and can include things like the date and time the shot was taken, camera settings like shutter speed and focal length, and copyright information, white balance, camera model and make, lens type and much more.
How to view EXIF data
There are many ways to access your photos’ EXIF data; I’ll try to make a simple list of them:
By using your operating system
This is the quickest and easiest way to read your photo’s metadata. But it requires that you have the photo file on your hard disk. You won’t see the full list of properties but you will get the most important ones, and this is often all you’ll need. It depends on the type of operating system you are using:
- Windows – Right-click on an image, select “Properties”, and switch to the “Details” tab.
- Mac OS X – Right-click on the picture, click “Get Info”, and expand the “More Info” section.
- Linux – Right-click the file and choose “Properties”. Depending on which file manager you’re using you may need to switch to a different information tab.
By using photo viewers
There are a number of free photo viewers that allows you to read the EXIF data, the following are two free photo viewers, you may download and installed them on your computer.
By using a browser plugin
There are a number of web browser extensions and add-ons that can be used to view the EXIF data of images online, this method is very useful because it allows you to read the EXIF data directly online and there is no need to have the photo file on your computer.
- Chrome Extensions
- Firefox Add-ons
By using an online service
You can also view your metadata or EXIF data online using an online service, for example, read EXIF data. This gives plenty of information but can be a slow way of doing things because you have to upload the photo file to the website or type the image URL which can take quite some time if it’s a big file.
By using your favorite editing software
For Lightroom users, you can quickly view the basic EXIF data by pressing I key twice, and the info will appear in the top corner. You can also find the EXIF data in Lightroom Library module under the Metadata panel.
For Photoshop users, you can find your EXIF data under File>File Info:
How to Edit/ Remove EXIF Data
You may choose to edit or even remove EXIF data from your images because you have some privacy concerns, or you want to protect your special photo shoot locations from becoming public, or you want to reduce the file size of your images. In these cases, you may try the following ways to either edit or remove your EXIF.
Using your operating system
When right clicking on your image file, the following snapshot is shown:
By choosing the “Remove properties & Personal information at the bottom of the menu, the following menu pops up and you have two options:
- Create a copy with all possible properties removed
- Remove the following properties from the file
In Lightroom, exporting an image will give you some alternatives in the Metadata section drop-down. You may choose one of the following:
- Copyright only
- Copyright & contact Info only
- All except camera raw Info
- All except camera & camera raw Info
- All Metadata
You can use the Save for Web dialog to remove EXIF data, from the Metadata section, you may choose from the following options:
- Copyright & Contact Info
- All except camera Info
Finally, I hope this post has helped you to know what EXIF metadata is and how you can use it to analyze and improve your photos. Obviously, you won’t want to use it on every picture you take, but it can be invaluable for getting to the bottom of why a shot turned out so well or bad.
Regardless of how you use it, there’s no arguing that EXIF data is a major development that comes with the invention of digital photography over old film photography. It’s an educational tool that can help you visualize your camera’s settings against a photo you’ve already taken.
