Summary
This article explores EXIF (Exchangeable Image File Format) metadata embedded in digital photos, detailing how this hidden data contains valuable information about each image including location, time/date, camera settings (lens, zoom, exposure, ISO, aperture), and other technical details. The author uses their personal collection of 73,281 iPhone photos over 14 years as a case study to demonstrate the wealth of information stored within image files and discusses various tools for viewing and navigating this metadata.
Key quotes
· 3 pulledAccording to iOS’ Photos application, I’ve taken 73,281 photos over the past 14 years of owning an iPhone.
Each one of those images doesn't just contain the photo you see as you scroll through the Photos app — it contains a wealth of information stored encoded directly into the image file itself.
It details useful metadata such as where the photo was taken (so that you can view your photos on a map at a later date), the time and date the image was taken at, which lens and zoom levels were used, the exposure, ISO, and aperture, amongst many others.
