Cameras and phones can write hidden data into a photo file: the coordinates where you were standing, the time you pressed the button, the camera's serial number, sometimes your name. Looking at the picture will not show you any of it. Anyone who receives the original file can read it. Drop one in and see what yours is carrying.
This page handles a few photos at a time. The portable version processes complete folders and ZIP archives, returns the cleaned files as a ZIP, and creates a log of what was removed from each image. It runs inside your own network, same as this one. Business licensing starts at $299. Email hello@dlsimage.com for licensing.
GPS coordinates recorded when the shutter fired. Accuracy varies with the device and the signal, but it is often close enough to single out one house. A photo taken in your living room points at your home. One taken at your kid's school points at your kid's school.
The date and time the picture was taken. One photo is a moment. A set of them collected over weeks starts to show a pattern of where you tend to be and when.
Camera make and model, and on many cameras the body's serial number. Photos from the same camera can carry the same number, which is enough to tie an anonymous post back to a named one.
Your name and copyright sitting in the owner fields. Add it to Lightroom's metadata fields once and it can ride along on later exports, including photos you meant to share anonymously.
Real estate listing photos, case and evidence images, claims files, event coverage. The portable version processes complete folders and ZIP archives locally, returns cleaned ZIP files, and creates a log of what was removed from each image. It runs on your own machines, inside your own network, and uploads nothing. Business licensing starts at $299. Email hello@dlsimage.com for licensing.
