Comments and Reviews
Can edit all kinds of image metadata, the best tool I found so far.
First experience is not good. Trying to add Lens data but only get errors and crashes continuously (particularly in 'Report' mode). Attempting to add new fields through the 'Add EXIF metadata' button for example results in EVERYTHING ELSE being removed. No way to simply copy selective data from one file to another? Import from file doesn't even work at all.
Does not have address bar. Have to click like 15 times to move to the folder I want to edit files in...
Also crashes when opening and closing 'Map panel'..
Buggy does not work as described and can't be uninstalled. Basically malware as far as I can see. Expect to have to reinstall your entire OS if you try it.
It's a 1.5mb zip file from their website, unless you download extras like Exiftool with it. It's practically a portable app.
