What is Exif data?
Exif stands for Exchangeable Image File Format which specifies formats for image and sound files.
In terms of photographic images, which we’re mostly dealing with on this site, you’ll see things such as:
- Geolocation data, if any. Note that this is added by smartphones and that some cameras have GPS enabled, but many high-end cameras do not. You can add GPS data into your image file, if it is missing, with some image processing software, such as Adobe Lightroom.
- The camera used in making the photograph.
- The lens model used.
- The date and time the photo was taken
- The aperature used in the photograph
- The exposure
- The focal length
- The ISO
- The image dimensions
- Shutter speed
- White balance
- Metering mode
Some of these items can be seen in some of the lightboxes on this website.

EXIF stands for Exchangeable Image File Format. It's a standard that specifies how image files can contain metadata, essentially extra information beyond the image data itself. This metadata can include a wide range of details, such as:
- Camera settings: Shutter speed, aperture, ISO, focal length, flash usage, white balance, metering mode.
- Date and time: When the photo was taken.
- Location (geotagging): Where the photo was taken, using GPS coordinates.
- Camera model and make: Information about the equipment used.
- Copyright information: Details about the image's copyright holder.
- Image orientation: How the image should be rotated for proper viewing.
- Thumbnail image: A smaller version of the image embedded within the file.
- Software used: The software used to create or edit the image.
- Description, keywords, and other custom tags: Additional information added by the user or software.
Think of it like a digital label attached to the image file, providing a wealth of context and technical information. This information can be very useful for photographers, image editors, and anyone working with digital images.
While most commonly associated with JPEG images, EXIF data can also be found in other file formats like TIFF and RAW files. It's important to note that EXIF data can be easily removed or modified with image editing software.
