Remember to ALWAYS remove the EXIF data before you post photographs.
Most modern cameras have GPS in them and tag the photo with very precise positions. One photo posted in the past couple days was sufficient to place the photographer in a room of the house, not just the house or street address... -----Burton 50+ year / Life / Emeritus ANA member (joined 12/1/1973) Life member: Numismatics International, CONECA Member: TNA, FtWCC, NETCC, EveryCountry (online) coin club Owned by three cats and a wife of 40+ years (joined 1983) Author: 3rd Edition of the Sample Slabs book, https://www.sampleslabs.info/ |

I did not know that, I assume that people here don't want their addresses publicized for fear of a burglary....

Is it correct to assume this is only on phone camera use?

You can use the Properties in Windows to scrub all of the meta data in your photos. The image processing website I use to combine images also scrubs it by default.
Most smartphones have geotagging enabled by default; turning it off should be the first thing you do when setting it up, and always check again after an OS update.

You can disable this "feature" in your Android phone. I am sure iPhone can do the same.
In Windows, if you look at the file properties there is a Details tab with a link to "Remove Properties and Personal Information" at the bottom.

Digital camera EXIF files are just JPEG (.jpg) files. To remove the comments (the date, GPS), just use an image editing program to save it in another format, such as a Windows Bitmap (.Bmp) or PNG (.Png) file. Then save it back as a JPEG (.jpg) file.  Edited by willieboyd2

I personally just don't usually have GPS switched on at my smartphone. It really drains the battery, often doesn't even work in dense urban areas, and is hardly ever useful unless I'm going geohashing.
(Of course, for all I know it might well be working automatically regardless of whether I switch it on or not.)
I won't be surprised if the Image Optimizer automatically scrubs EXIF data anyway (on cropping, at least).

More and more it's not just cell phone cameras. High-end DSLRs are becoming connected.
I know the Nikon all weather camera had GPS, but we turned it off because of the battery suck. Newer chips are much better at using limited power.
If your phone lets you turn it off, some apps "helpfully" turn it back on... "Don't you want your friends to know where you are?"
I know the photo I saw had been cropped to 640x480, but not how it was done. I only noticed because I have a browser extension that shows EXIF if I hover over an image.
I would -hope- but haven't tested that the optimizer scrubs.
Even if Bobby were to strip EXIF from uploads, linked photos might still leak data.

If you want a simple way to know if your camera or phone is capturing EXIF data, locate a photo you don't mind testing online, and go to: https://readexifdata.com/I tested a phone photo, and two camera photos, and none had the location data captured. Edited by nss-52

On the iphone, simply turning off location services takes care of this.
