how to use exiftool to change metadata pdf mac

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. find /path/to/top/directory -name '* * *.How to Modify Metadata of Your Photos Using ExifToolĮarly this year, I got my first camera with a 16-50mm kit lens to start learning more about photography. To process all the files in a directory and its subdirectories recursively, use find.

#!/bin/shĮxiftool -Author='$author' -Title='$title' -CreateDate='$year' '$filename' To process all the files in a directory, put that code in a loop. #!/bin/shĮxiftool -Author='$author' -Title='$title' -CreateDate='$year' '$1'Įxplanation: I use parameter expansion constructs to perform some basic string processing: put the base name (after the last /) into title put the part up to the first space into author and remove that from title repeat with the year. Here's a script that processes just one file (pass the name as the sole argument of the script). So let the shell call the program with the right parts of the file names. Some EXIF manipulation tools have a built-in way to rename files based on EXIF data, but I don't know of one that can do it the other way round.
