![]() Now I'm looking at an Exiftool config file looks like it could permit adding lenses to the list. Here is the Exiftool link to Nikon Exif: That does not make it easy to update Exif with the actual lens used because, of course, the Exiftool list for Nikon does not include all the world's weird lenses. Instead there are some identifying numbers which Exiftool is translating to produce this output.Įxiftool has a Nikon lens list which is used to correlate the actual Exif code to a Nikon lens. When I run Exiftool on one of my nef files to find out the lens type, I get the following output (for example).īut that output is NOT what is actually stored in the Nikon Exif. Turns out the whole thing is much more complex than I thought. Looked further into the Lens type issue in Exif because like everyone else I have some "unknown" lenses. And if you’re on Linux… Well, you know better than me how to do this ). On Windows, you can “copy as access path” in the right click menu. ![]() ![]() On OSX, you simply read the info (Cmd+I). ĭepending on your OS, the way to get the absolute path of a file is different. Like this:Įxiftool -Lens="Lomography Zenit New Petzval" -LensModel="Lomography Zenit New Petzval" -FocalLength="85" -MaxApertureValue="2.2" -m -overwrite_original_in_place "Absolute/path/to/your/file1" "Absolute/path/to/your/file2". If you want to edit several files, you can specify them one after the other, separating them with a whitespace. The command is all on one line even though it may appear wrapped here in the forum window.Įxiftool -Lens= "Lomography Zenit New Petzval" -LensModel= "Lomography Zenit New Petzval" -FocalLength= "85" -MaxApertureValue= "2.2" -m -overwrite_original_in_place "Absolute/path/to/your/file" The command line will look like this (well, at least under OSX Terminal… I don’t know about Windows).Īn argument name is preceded by a '-' and followed by an '=' when the argument needs contains a value. Focal length: 85 (do not mention the unit which is always in mm).Lens model: Lomography Zenit New Petzval.Lens name: Lomography Zenit New Petzval.In this example, I will tag photos for my New Petzval lens. You installed ExifTool and are now ready to execute your first command. You CAN contaminate a file if you make a mistake.ĮDITOR'S NOTE: I DON'T THINK THIS TUTORIAL WORKS AT ALL!!!! I'm going to cross it out. *********************************************Īnyone new to this stuff, please do practice first on a copy of a photo file.Īnd make backups of any photo file to which you are going to apply EXIF changes before hitting them with Exiftool writes. This will also overwrite any existing lens info. You may be aware that the serial number of your camera and lens are stored in the EXIF data of the photos taken with it. It enables you to switch to the desired one from the slide bar, you can also delete the unwanted one or check the detailed EXIF information of the ORF file via the I icon from the bottom left corner. Here is an excerpt from the tutorial showing how to add lens info to the EXIF of a photo file. Step 3: To browse the details and EXIF information of the ORF, you only need to double-click the ORF file to go to the Full Screen mode.
