On Mac or Windows, simply type EXIFTOOL in the command line, and then a space, and then drag the image file in question onto the command line (which automatically enters the path to the file).
Download and install the code, and via the Windows command line or the terminal window on a Mac, you’ll enter simple text commands to view the metadata. Available for Mac and Windows machines, ExifTool isn’t exactly a warm and fuzzy application, but boy does it deliver on a simple promise: to help you view and edit metadata (including many other types of data beyond the EXIF of its name). If what you want to do is to really dig into the wealth of information-as in, the pages and pages of information-contained in the EXIF data of a given image file, then you should download the free open source ExifTool software from developer Phil Harvey. Now all those underexposed images scattered throughout the take are normally exposed, and it was facilitated by Lightroom’s ability to harness EXIF metadata for filtering groups of images. You can then make an edit to the brightness of one file and apply it to all the others in the group (which are all ƒ/8 and one-third under) before returning to the unfiltered set. Click on ƒ/8 and the view will switch to just those images that are a third-stop underexposed.
Choose Aperture and you’ll be presented with filters for all of the apertures included in the folder you’re viewing-in this case, ƒ/8 and ƒ/7.1. Click on any heading and a dropdown menu of options appear. Instead, click the Library Filter toolbar found atop the thumbnail view in the Library module and then click on the Metadata heading to sort by a variety of metadata attributes including focal length, ISO and aperture. But since they’re scattered throughout the take, finding and editing them one by one would take forever.
In the end, perhaps you decide that those shot at ƒ/8 are one-third stop too dark. For instance, let’s say you photographed a set of images at two different apertures-ƒ/8 and ƒ/7.1. Along with its powerful tools for organizing and editing RAW image files, Lightroom offers tremendous capability for working with metadata-both by adding and editing custom IPTC metadata (things like copyright and contact information) and by accessing much of the EXIF metadata contained in an image file to help sort images by attributes.
