Hello to everyone.
I am currently working on Windows 7 HP with ExifTool version 11.2.5.0, processing .JPG pictures from camera traps for wildlife studies. I would like to extract the ambient temperature (and possibly the moon phase) from the metadata of the pictures; I know the cameras record them as they get watermarked onto the pictures. We have different models of cameras (Reconyx, Bushnell, Moultrie and ScoutGuard) and I'll upload a picture from every camera model. IMG_0001 is a Moultrie, IMG_0002 is a Reconyx (that didn't experienced problems) and IMG_0003 is also a Reconyx (that experienced problems in storing date and time, see below), IMG_0004 is a ScoutGuard, IMG_0005 is a Bushnell and IMG_0006 is an unknow model.
In some of the pictures, the temperature information is stored in the "comment" section (like in IMG_0003). I extracted the T° from that pictures thanks to FAQ#12, but in the others pictures I couldn't. I would like to know if it is an information that is not stored in the metadata (as another user already experienced: https://exiftool.org/forum/index.php/topic,9383.msg48543.html#msg48543 ) or if I'm not able to find it.
"fun fact": the only picture from I could extract this information is one of the pictures that experienced problems storing date and time ( https://exiftool.org/forum/index.php/topic,9834.0.html ).
Thanks for the attention and sorry if I'm asking dumb questions - I'm still a newbie of this world.
Best regards,
Lisa Tedeschi
I download one of the photos. Have these been edited as there is this tag:
[XMP] History Software Agent : Adobe Photoshop Camera Raw 11.0, Adobe Photoshop Camera Raw 9.7 (Windows)
Do you have the original photographs as editing software sometimes destroys information.
I'm also seeing this:
[ExifTool] Warning : [minor] Unrecognized MakerNotes
If there is data in there, I'm afraid it's beyond by skill level.
Hi Alan, thanks for answering.
Yes, I used AdobeBridgeCC to tag the pictures.

Yes, here is IMG_0007 that has not been processed through AdobeBridgeCC, and IMG_0008 that was processed. I can actually see in both images the metadata I was looking for (temperature and moon phases), but not in the others pictures I uploaded before.
Best regards,

Do you have the original for 0005?

unfortunately, no.

0005 was edited with an earlier version
[XMP] History Software Agent : Adobe Photoshop Camera Raw 11.0, Adobe Photoshop Camera Raw 9.7 (Windows)
and it has a strange copyright injected into it
[XMP] Rights : Copyright 2002
so its a shame you haven't the orginal.
Maybe Phil will be able to extract the maker notes when he comes back from holiday.

I definitely agree. Thanks!

Hi Lisa,
I've taken a look at the images you posted:
IMG_0001.JPG - The makernotes are 3 unknown bytes. It is possible that the temperature is here, but I doubt it.
IMG_0002.JPG - ExifTool extracts the Reconyx AmbientTemperature
IMG_0003.JPG - The temperature is found in the Comment tag
IMG_0004.JPG - The file contains a large unknown trailer, but I can see no temperature metadata.
IMG_0005.JPG - The unrecognized makernotes contain no useful information. I can see no temperature metadata.
IMG_0006.JPG - The makernotes are 14 bytes of unknown data. This could possibly contain temperature metadata, but without more samples at known temperatures I can't say for sure.
