If you need to know more details about an image, like what device was used for the shot, aperture value, lens model, exposure value, and more – you can do so in Finder. In order to do this, open Finder and go to View > Show Preview. Next, select an image, right-click on it, and choose Show Preview Options. Under Show info, tick the checkboxes next to the values you want to view upfront in the preview. Once enabled, tap on an image to view its metadata in the preview section.
