11:37:56 <b_jonas> I wish my compact camera wrote into the metadata the timezone (which you can configure in the settings), sub-second exposition time (this camera is fast enough that it's easy to make multiple photos in a second); and the orientation data from gravimeter (it displays it in two dimensions on display while composing a photo, but only writes a single multiple of 90° orientation).
12:17:13 -!- arseniiv has joined.
12:31:28 <fizzie> Is there a standard metadata field for that last one? The usual EXIF orientation field is an enum with 8 values (90 degree multiples + mirroring bit).
12:32:09 <b_jonas> fizzie: I don't know, and in any case that standard orientation field is useful because software use it to rotate the image for displaying
12:33:02 <b_jonas> so this would be an additional field. but these days these kinds of gravimeters are really cheap, they're built into many devices, so there's probably either already a field or they can just invent a new one.
12:33:23 <b_jonas> a lot of the non-exif metadata fields are defined by camera manufacturers anyway.
12:34:02 <fizzie> Apparently there's an Apple-specific acceleration vector field, so some devices do store it.

12:38:31 <b_jonas> fizzie: exiftool docs say that there's even AccelerometerZ, AccelerometerX, AccelerometerY tags for the Panasonic image headers, which is a type of header set that this camera writes already (since it's a Panasonic)
12:38:51 <b_jonas> and also RollAngle and PitchAngle fields in the same
12:39:21 <b_jonas> they won't be very accurate, but even so it'd be worth
12:40:06 <b_jonas> there are also tags defined for other brands
12:40:24 <fizzie> Hmm. Wonder if my Canon camera writes those. Haven't noticed in exiftool output, but haven't tried to look for it either.
12:40:44 <fizzie> It does write the time zone, I remember that much.
12:40:56 <b_jonas> fizzie: do you know if it has an accelerometer hardware?
12:41:39 <fizzie> It has a horizon thing in the live view, so it would need to have something to display that.
12:47:38 <fizzie> Heh, it writes a "Camera Temperature" tag.
12:47:53 <fizzie> ("32 C" for this image.)
12:49:37 <b_jonas> does it vary among images?
12:50:09 <b_jonas> and does it get that from a temperature sensor in the camera, or from one in a connected GPS or mobile phone etc?
12:51:55 <fizzie> Yes, it does seem to vary among images; in this set of 109 images, it starts at "28 C", and goes up to "32 C", in a more or less linear fashion. So I guess it was warming up while shooting. It's not connected to anything, so it must come from a sensor somewhere in the camera.
12:52:20 <b_jonas> nice
12:53:05 <fizzie> There's also a "GPS Version ID" ("") even though there's no GPS or position data.
12:53:34 <b_jonas> that said a lot of the metadata that it writes is useful
12:54:10 <fizzie> (I've sometimes used one of those pieces of software to attach positions to images, based on a recorded GPS trace from a phone.)
12:55:01 <b_jonas> tags about exposure settings, white balance, the second precise timestamp (it's unclear what it is a timestamp for: the start of exposure, when it starts to compresses the file, when it starts to send the file to the SD card, etc), the camera model, etc
12:58:25 <b_jonas> mind you, I often don't set the clock of this camera correctly, eg. sometimes I forget to reset it when I remove the battery for a short time to access the SD card, or just forget to set it for a long time, so the timestamp is often up to 10 minutes early or late, and also sometimes 1 hour off due to incorrect DST setting
12:58:55 <b_jonas> if my next camera doesn't write timezone metadata then I'll probably just set it to always UTC
12:59:27 <b_jonas> (or to Iceland if it doesn't allow UTC)
13:08:53 <fizzie> I keep forgetting to set the camera's clock (or time zone) every other time I go out with it, and it's annoying, because I tend to take photos with the camera *and* with a phone, and then their sort order is all wrong when mixed together.
13:08:57 <fizzie> So in a lot of my folders of photos, the last image is of the phone with a clock on the screen, because then it's easy to compute a correction factor, and use `exifdates -AllDates-=X` to fix them.
