Tech Data in the Gallery

[Rob-F]

In the gallery, much of the time, under EXIF it will display "Lens Data has not been set." And apparently no other info has been set, either. Yet people will post comments, "I see you used your 28mm lens for this shot," or "I like the way that Fuji film renders" or "I used to have that same model Blinkoflex."

Where are they getting all that info, when the tech data field is blank?

Dunno. I did a catch-up project this year of filling in as much of the EXIF for my film shots in the gallery as I could, and noting the lens (when adapter-mounted) on digital bodies.

A fair number of folks specify the camera/lens etc. in the title/caption; some add notes.

But perhaps some RFFers are clairvoyant, but don't make a big deal of being able to divine lenses from uncaptioned images ;-)

Yes, some posters put tech data in the Notes or Comments, perhaps unaware one can populate the EXIF panel fields by clicking the "Show/Hide Photo Detail Editor" link just above the Comments box.

As to clairvoyance... if you capture the photo and download it to your own machine and then look at it with a photo editor that can read EXIF info, there can be info there that should (but may not) also find its way automatically to the gallery. Also, some delete all their EXiF info in preparation for uploading...

I often correct or add to the files' EXIF (as when the lens misinforms or doesn't inform the camera) with the little ExifChanger program. The program then writes out a copy of the DNG with the updated EXIF.

Does this mean there's a way to add to or correct EXIF data in the computer? Or just in the RFF gallery. I most often want to fix my EXIF in my computer when my M8.2 doesn't pick up the lens data from my Sharpie coding, or gets it wrong.

Oops, my error, I gave the wrong name to the free Mac/Windows application... correct name is ExifChanger, by Marc Rochkind. His web page dealing with these small apps: http://basepath.com/new/index1.php

Rob, yes, that's how it works. I wasn't clear enough that the program edits your raw file on your computer and writes out a copy with modified EXIF info. I only use DNG raw files, so I'm not sure what other types of raw it may handle.

The latest version of the program also allows you to make the program over-write your original raw files with the modified ones. The convenience of this is that the resulting files have the same names and are in the same location as the originals. Now, one may reasonably feel uneasy about not retaining a copy of the originals, so you could (before editing) simply duplicate the folder/sub-directory containing them and stash the copy somewhere safe. 🙂

Is there a way to populate the Gallery EXIF data fields at the upload stage?

Hi Lynn, yes, you can edit the EXIF panel field info by clicking the "Show/Hide Photo Detail Editor" link just above the Comments box. This opens up data entry fields for input.
