Hi,
I am doing lots of nodal point panoramas, and the stitching software wants to know the focal length of the lens used. It reads it from the Exif data. This data is not present if using a tech cam.
When working with a tech cam, I am wondering how you can know which lens was used with which photo ? (I assume I can't recognize the lens by it's "drawing" simply by looking at the picture ).
Here are a few ideas I came up with:
- Take notes with pencil and paper. Sounds awfully low tech
- Take a picture with the tech cam of a piece of paper (or iPhone with the notepad), on which you have written the settings. Do this each time you change lens / settings (if you want to record what aperture was used). Awful lot of Mpix used to record Exif, but you can delete those pictures once you have added the info to the Exif data in Lightroom (or something else). Advantage is that if you sort the pictures by capture time, it should be easy to sync the Exif for all the pictures you took in one go with one lens / setting. For the moment, this sounds the easiest solution.
- Take photographic notes with the iPhone. So for example take a picture of the lens (aperture / exp time) every time you change a setting. If the digital back and iPhone have the same clock time, then you should be able to figure out which picture on the DB was taken with which setting. Maybe even importing the iPhone images into Lightroom and sorting by capture time allows to achieve the same results as the previous method.
- If you have an IQ back, use the star system to code for the lens (e.g. 1star -> 32mm, 2 stars -> 50mm or something like that).
- Maybe there's a way to recognize the LCC shots, which are needed ? I don't have enough experience about that to say.
- Any other ideas ? How do you do it ?
BTW, I found this Lightroom plugin, which seems to do what I want (modify Exif data for focal length in lightroom), once the lens is identified:
LensTagger now with Analog Camera & Film support
Thanks in advance !
