A Lightweight EXIF Data Viewer
(Note: This post originally appeared on my new mostly-non-photography blog [robotsprocket])
If you’ve read the title of this post and are wondering “what is this EXIF thing?”, then here’s a bit of information. EXIF is an acronym for EXchangeable Image File Format. And, no, I don’t know why it’s not “EXIFF”. Basically, it’s metadata tagged onto a digital image that contains information about that image. This, along with another group of metadata, IPTC, is used by digital photographers to keep track of information about such things as camera/lens settings, geographic information and copyright of a given photo.
Some photographers post their images online with this information intact, while others will strip it out when posting, keeping their secret sauce to themselves. For myself, I keep it intact as I hope it might be helpful to other photographers to understand how a photo was capture as well as being an aid in enforcing copyright. Most, if not all, photos on my photography site have this data tagged onto them and the basic data can be viewed by clicking the “View Photo Data and Location” button under the photo:
However, there are a lot of times that I want to view this data locally for unpublished photos on my PC. To make this easy, I wrote a simple Windows application that will display this data for a selected photo:
It displays the most-commonly used EXIF data on the main interface; and, if there’s GPS information embedded in the metadata, it shows a button to view the photo’s location on Google Maps. If you want all the EXIF data, you can click “File→Show All EXIF Data…” and a dialog will appear showing everything:
A couple of installation notes:
When downloading the installer, you may get this warning:
Because this app hasn’t been installed enough times for Windows to “trust” it, Windows Defender wants you to really think about it before installing. To continue, click the three dots and choose “Keep”.
You might then get another warning:
Go ahead and click the down arrow next to “Show more” and click “Keep Anyway”. Then, navigate to your download location and doubleclick EXIFViewer.msi to install. You might get another warning:
Click More info and you’ll get the option to run anyway. At this point, the installer will launch and you can install the application.
A lot of rigmarole to install an app, but it’s for most people’s own good, as Windows tries its best to prevent you from installing malicious software using Defender Smartscreen. In this case, you’re going to have to trust me that this isn’t malicious. You have the option, of course, to review the source code at the Github repository listed above. And you know where to find me. If enough people install, Windows will eventually allow it past Smartscreen without complaint.
