Is there a way to remove all metadata from a JPG via DO without having to install a command line app?
Is there a way to remove GPS data from multiple photos at once? I tried with DO v11.17, and it does not seem to work. If i select multiple photos, the GPS data says multiple values in it. If i go into that and try to erase what is there or put 0's and apply the changes, nothing happens. Even if i try to put 0's when a single photo is selected does not work. However making other changes to multiple photos like changing the fstop seems to work ok.
Often when i post photos, i want to remove certain data from the photos, primarily any GPS data, while wishing to preserve the rest. I have a command line program called jhead that i can drag my photos to and it does what it needs to do, but it strips all metadata, not specific fields.
Using the metadata GUI as you were doing already, you could set all the images to a particular GPS position. All zeros should work fine, as long as you edit the values in some way (e.g. mousewheel up to 1 then back to 0) so it knows you want a value there and didn't just click by mistake.
You can also clear out the values entirely, for all selected files, using this command:
SetAttr META gpsaltitude gpslatitude gpslongitude
Note that some images and cameras store metadata in other formats, not just EXIF. Opus only currently works with the EXIF data and won't clear any other type, so you might want to make sure the data isn't still in the file via another metadata standard. If it is then you will still need to use a separate tool to clear it out. EXIF is the most common but there are other formats and files can use more than one at once.
