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. It also does super cool stuff like let you offset all the date-related tags by an hour with -AllDates+=1:00.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. The inherent sexy power of the -if construct is thrilling. name \*.jpg -print0 | xargs -0 exiftool -n -if '$File:ImageHeight > $File:ImageWidth' -IFD0:Orientation= I did it with almost no effort, thanks to the incredibly wonderful exiftool, which can happily say I've put to use as a stand-alone perl script, a perl library, and a stand-alone Windows EXE.įind. So in newer, savvier, orientation-aware image viewers (like ZoomBrowser or, in fact, Photosleeve) the image gets double-rotated.Īs a quick fix, I've just cleared all the Orientation tags on Tall photos.
Specifically, we rotated some of our original images in a way that did not reset the EXIF Orientation tag.
One challenge is that some of my EXIF data is inconsistent. I've been working on how to get the stuff out of my private gallery2 instance and onto Photosleeve. I have a large back-log of photos sitting on my mass storage, basically since the kids were born.
