EXIF data and orientation

EXIF (Exchangeable Image File Format) is a standard for storing interchange information in digital photo files. Data such as shutter speed, exposure compensation, F number, what metering system was used, if a flash was used, ISO number, date and time the image was taken, whitebalance, auxiliary lenses that were used and resolution are stored by new digital cameras. Some images may even store GPS information so you can easily see where the images were taken!

Every time you take a picture with your digital camera or phone, a file (typically a JPEG) is written to your device’s storage. In addition to all the bits dedicated to the actual picture, it records a considerable amount of additional metadata. This data can include date, time, camera settings, geolocation coordinates, orientation, etc. Photo processing software, like Photoshop, can also add further metadata to EXIF.

A lot of this stuff is mundane, but it also can contain potentially sensitive information, like geolocation data (GPS coordinates where the picture was taken). That means, if you are sharing images with metadata there is a lot of details others can glean from them, expecially geotagged data. Moreover, this information increase the file size, specially with small images like the ones used on responsive web designs. A right image optimization process removes all this information before compressing the image.

Viewing EXIF data

You cannot stop EXIF metadata from being added to your photographs. It is also a good practice to save this information, since it provides useful information to manage your photo gallery later. Creation dates, geotagging, and camera settings and orientation are valuable data which can be removed later, when the images are shared and published.

One of the most powerfull tools to view metadata information is ExifTool. This open source tool is platform-independent command-line application for reading, writing, and editing meta information in a wide variety of files. ExifTool works on Windows, MacOS, and Linux and it supports many different metadata foramts including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, etc. as well as the maker notes of most of digital cameras.

For instance, we are going to take a picture from StockSnack and see the metadata in it.

Some valid image and photo file types are: JPG/JPEG, TIFF, GIF, PNG, PSD, BMP, RAW, CR2, CRW, PICT, XMP, DNG.

Geolocation data

Geolocation data are useful for geotagging, which creates all kinds of new possibilities, such as allowing users on photo-sharing sites to see any images taken in specific locations, view where your pictures were taken on a map, and to find and follow social events. Howevere they are a data leak when they are directly shared on the Internet.

Photo settings

Metadata are specially sensitive for photographes, where lots of information are shared in it, like location and camera settings. This kind of information is very useful to day-to-day work, but it must be removed when the image is published and distributed to avoid private and professional data leaks, like with stock repositories.

EXIF orientation

When images are photographed, digital cameras use orientation sensors to store an EXIF orientation value for how camera is held. This information is used later to automatically rotate your photos, saving you of this manual task.

There are 8 possible EXIF orientation values, which reflect the position of the camera with respect to the ground, numbered 1 to 8:

Flag Orientation Description
1 0 degrees the correct orientation, no adjustment is required.
2 0 degrees, mirrored image has been flipped back-to-front.
3 180 degrees image is upside down.
4 180 degrees, mirrored image is upside down and flipped back-to-front.
5 90 degrees image is on its side.
6 90 degrees, mirrored image is on its side and flipped back-to-front.
7 270 degrees image is on its far side.
8 270 degrees, mirrored image is on its far side and flipped back-to-front.

In the 7 scenarios – 2, 3, 4, 5, 6, 7, 8 – the image need to be rotated before orientation stripped. Most common photo management programs read EXIF orientation to show photos on the right position. However, browsers don't perform this task, which means that the image or photo must be rotated before web publishing.

When you rotate or flip an image, EXIF orientation must be removed. Most programs do this task correctly, however some programs don't: like Windows Photo Viewer or Microsoft Paint. If you have some problems with photo rotation, you must fix this issue with a editing software like Photoshop, GIMP, or OSX Preview.

Removing EXIF metadata

Metadata waste several kilobytes and result in data leak. This is why is recommeded to remove EXIF data when images are published and distributed. Morevoer, images need to be rotated and correctly compressed for web pusblishing. To automatically perform all this tasks, you can easily take advantage from our bulk image compressor for web, and get perfectly optimized images for web with the best quality.
