If you are a beginner in photography, you may not know what EXIF is. But as you dig deeper into the field, knowledge of EXIF becomes a must. You might think photography is an art but with state-of-the-art hardware, it’s just about specs and numbers.
Contemplation of photographs is highly subjective. It is influenced by factors that affect fans beyond your control. On the other hand, specifications, details and numbers are facts, true or false and therefore are not subjective.
These numbers and specifications provided by your camera can be of great help when you are trying to improve your photography. With EXIF data, quantifying the difference between a good photo and a bad one becomes easy. What did you do in the other shot that made it so good? Is the focal length different, or is it the aperture?
This is what EXIF data does for you. It gives you the chilling numbers of each and every picture you click.
EXIF in detail
EXIF stands for ‘Changeable Image File’ data and contains information about the image along with some meta data. This is a common standard, and whether you use it or not, data tracking is enabled by default in most modern camera devices.
It is embedded inside JPEG, TIFF, PNG, MIFF and DNG images.
Find EXIF data in Flickr and 500px
Many photographers spend time browsing beautiful and breathtaking photos on photography sites like Flickr and 500px for inspiration.
But if you want to dig deeper and know exactly how the photo was taken, read on.
Flickr
In the new and improved Flickr, go to the right sidebar and scroll down until you see a circle with letters I.
Tap it to get some basic information like camera and aperture. Click Show all Exif link below to get advanced options.
500px
500px doesn’t offer as detailed EXIF data as Flickr but when it comes to your camera’s ISO, focal length, aperture, shutter speed, and position, you’re covered.
Note: On Flickr and 500px, you may come across some photos that don’t have EXIF data to display. This is because the uploader chose to hide the data for security purposes.
Chrome Extensions
There’s a simple Chrome extension to give you the most basic EXIF stats in the entire known universe. OK, maybe it’s an oversold but it works well (when possible) and is super simple to use. It’s called EXIF Viewer.
The problem with finding EXIF data for images uploaded on sites like Imgur (Reddit) and even Facebook is that for the most part, all the information is discarded.
But where data is available, this extension has a specific skill set that allows it to search the data, extract it, and show it to you.
How does it work, you ask? Just hover the mouse pointer over the image, it will search for data and if it is available, it will display it. I have tried a lot of other EXIF viewer extensions and most of them are more complicated.
Firefox Add-ons
The best add-on in Firefox for accessing EXIF data is called Exif Viewer (notice the subtle difference in capitalization in names compared to Chrome extensions).
After installing the add-on, locate the image, right click and select View image EXIF data and all available data will be displayed.
The nice thing about this add-on is that it also works with local files.
But there is no other way to launch the extension window. So when you want to look up EXIF data for a local file, just open the extensions menu by right clicking on any link or image then select Local file option to browse and select any image file.
EXIF data security
Nowadays, privacy is a big concern for every internet user. What is your view on the free sharing of information on the internet? Do you think EXIF data for images should be freely available? Did you personally choose to hide it? Let us know in the comments below.
