I was listening to a photo discussion where it was suggested that we should find our focal length, i.e., how we see the world, by looking at the focal length that was used in our favorite images.
Looking in the Catalog tab, I see a section under technical named Focal Length. I lists the focal length of all of my images. I applied a filter in the middle image review section but that didn't limit the results.
How do I list the Focal Lengths of a subset of my images?
How do I export the resulting data into a file for analysis?
Similarly for the other technical values like F-number, Lens Information, etc.

Re: Technical data - Focal length
Thank you very much. That is exactly what I need to better understand what I used to make my best images. It will help refine what equipment I will take on future trips.

I also downloaded and tried the script "Full Exif dump" on a set of 1537 images but I get a Not Responding error every time in build 3.3.0.2606 (64 bits).

Just tried it on 250 images and it took about 1-2 minutes on my core i7 Win PC
Try it on 1 or a few images first to see if it's actually working for you.

Re: Technical data - Focal length
Ah, patience is a virtue.
Tried it on 12 images and it works, sort of.
The output is on the screen. When I select all and copy, The row GPSProcessingMode=ACII doesn't get selected and the paste ends there.
Any reason why copy paste should stop? Is there an easy way to have the script output to a file (CSV) instead?

Re: Technical data - Focal length
Here - when the "Full Exif Dump" script completes, the output is automatically selected so one just needs to copy. Having said that, none of my images contain GPSProcessingMode, so I am not sure if that is making a difference or not.

The following is another solution.vkfoto wrote: 11 Dec 17 3:14 Is there an easy way to have the script output to a file (CSV) instead?
Are the fields one wants to export to CSV shown in Details?
If not ... it is possible another Metadata Details "template" (templates may not be the exact term) contains the fields. Go to Details. In the upper right, below the View button, there is a small icon with three lines. Click on the icon and one can choose different Metadata Details templates.
The Advanced template contains EXIF information. Once enabled, the EXIF information is found under the Technical section. Focal Length is listed.
If all the fields one requires are included in the template chosen, right click on the images, go to Metadata - Export Metadata To CSV File.
(Note: The fields displayed in the Select Items window (after clicking on Export Metadata To CSV File) are dependent on the Metadata Details "template" selected.)
Select the fields. Click on OK.
If the fields one requires are not included in any of the templates, one can map these fields to Custom Fields. Regardless of the template chosen, Custom Fields are always included in the Select Items window.

Re: Technical data - Focal length
I think I've figured it out.
When I select an image made by my 80D, M5 or G11, the Full Exif Dump script works fine. Some of the fields are different between the three camera but perhaps that is normal.
When I select an image made by my cellphone, most fields (green) correspond to those of my above cameras while several fields (yellow) have no correspondence but the copy paste stops just after the first field GPSProcessingMode=ASCII. That field is not auto-selected and if I try to manually select it, it doesn't get highlighted, as if it is not there. Since none of my cameras have a built-in GPS or an external unit to record the GPS data in camera, I don't know if the GPS fields are causing this glitch or if the cellphone data is doing it.
Meanwhile, thanks to the hint about using the Details and saving the meta data to CSV, I can get the information out and into Excel to analyze it.

Re: Technical data - Focal length
The ASCII marker is followed by 3 0-characters, again followed by its value. That is how ASCII fields are stored. But PSU strips that for display but it will only do so when the Exif tag is marked as a text tag type (an ID separate from the value). Your phone probably doesn't mark the tag as a text tag and so PSU will just dump the value. So you end up with: ACSII#0#0#0some value
And a 0 character is typically the end marker for a text string. Hence why the copy/paste is truncated at that point. The OS thinks that the string ends at the 0 character.
If you can send me a sample image from the camera I can check if I can alter the script to ignore 0-characters

Re: Technical data - Focal length
Here is a sample from my cellphone that causes the Full Exif Dump script to stumble. Included is a screenshot of the place where the stumble happens as well as a text file with the result of the copy / paste.
