Have you ever forgotten to set the date/time on your digital camera before taking a bunch of pictures? ExifTool has a time shift feature that makes it easy to apply a batch fix to the timestamps of the images (ie. The OS X package installs the ExifTool command-line application and libraries in /usr/bin.Īfter installing, type "exiftool" in a Terminal window to run exiftool and read the application documentation. Mac OS X Package: ExifTool-7.98.dmg (1.4 MB). I have always found Phil Harvey's EXIFTool to be fantastic. Go the directory containing the images to be converted.There will be quite a few tools that work on the JPEG EXIF fields. ProTip: For Mac users with Homebrew, may get ExifTool via brew install exiftoolĪfter the installation, open your favorite console emulator. Below are the steps I made in order to address the issue.ĭownload and install ExifTool ( may follow the instructions here) This free software is created by Phil Harvey and is platform independent. My main objective is to clear the value of the FocalLength and LensModel properties of all the images. In order not to further spread false information, I tried to find a tool that can modify metadata of images. If you will view the image in Flickr, you will notice that the Lens Model is set to 12.0 mm but I really took the shot using a 35mm lens. Below is one of the images that have incorrect Exif metadata. I only noticed this discrepancy after uploading some of the photos to Flickr. All the photos that I have taken resulted to have 12mm focal length on their Exif metadata. Upon changing lenses, I forgot to update my camera settings to the actual focal length of the lens.
But from time to time, I have been changing the lens of my camera to 35mm depending on the subject. I initially set my camera’s focal length setting to 12mm given that I am using a full manual lens. The experience is very engaging and quite fun! Problem
Try it out: Take pictures using a prime lens and focus manually. On my camera, the focal length can be set manually but I eventually encountered a trivial problem. Information like aperture and focal length will not be detected automatically. The lenses are full manual and the camera wouldn’t be able to communicate with them. I bought relatively affordable lenses but with some consequences. As months pass, while taking more and more photos, I wondered how faster and shorter lenses behave. I did not borrow the camera of my wife as she’s using it during trips.
