Extracting Temperature/Lunar Phase Metadata

[J Killam]

Hello there,

I've viewed a discussion from 2015 but wanted to make absolutely sure I am doing everything right. I have a ton of photos from Bushnell Trail cameras (32mp core ds-4k) and I want to extract the temperature and moon phase which is printed on the photo on the bottom banner. I use Timelapse via Saul Greenberg to tag wildlife species in the photos which has integrated Exif to be able to extract available metadata.
However, I can't figure out how to extract temperature or lunar phase. I also tried the Exif tool downloaded to my windows computer and still don't see temperature metadata. I'm attaching two raw photo files as well as my readouts through the exif tool on my desktop as well as through Timelapse. Sorry if this is redundant to previous posts and thank you in advance for any help!

I see a MakerNoteUnknownText which can be listed with the -b (-binary) option. I don't know if any of that is helpful

The UserComment and ImageDescription contain... something

The -u (-unknown) option doesn't pull up any unknown tags.

Looking at the file in detail with the -v3 (-verbose3) option doesn't show any unknown chunks of data.

Phil will have to verify, but if none of the above data is what you are looking for, then I don't think it's been embedded in the file. Even though it's been hard-coded onto the image itself, that doesn't mean the camera embeds the data in the file.

The "T61F" in the UserComment looks like it's the temperature. "RM031" is also there and on the image. So that leaves  "C[P] R0S9", ":P0000", and "M3" as unknowns in that data.

Do you have some shots from different phases of the moon? Would the M3 value change between them?

I can't see anything that StarGeek has missed.
