EXIF v2.31 (p49) defined time-zone offset fields in 2016 and the XMP time-zone guidelines (p33-34) also consider time-zones. The implementation in cameras and programs is rather minimalist at the moment.
See also my answer to an older question: What do you do with your camera clock time in relation to time zones?
Good news, this is now natively supported in Picasa
Tools > Options > Name Tags > "Store Name Tags In Photo"
You can also force Picasa to start the writing process using
Tools > Experimental > "Write Faces to XMP"
Verify this worked with using an EXIF viewer to verify a normalized XMP region with a name was written to the ...
CIPA DC- 008 is the standard for Exif 2.2. Of note it makes no mention of "timezone." "GMT" is also not mentioned either. The term "UTC" does appear but only specifies the GPS time is recorded as such. Pedants may note that this is slightly misleading since GPS time is not identical to UTC
My point, in short, is that omission of timezone is likely not ...
You are right that Faces are not part of EXIF but XMP. You can take a look at Daminion (where I work). It can import face information from Windows Live Photo Gallery and Picasa into the People tag. All your image annotations called tags in Daminion can be synced with your image metadata as EXIF/IPTC/XMP/MWG and "travel" along with your files including face ...
Lightroom is strongest in VIRTUAL organization. You have numerous choices, among them (and not mutually exclusive):
You can physically (on disk) organize in any way convenient; I
personally prefer by date shot
Photos can be given keywords, such as "Soccer" or "Picnic". Those
could actually be a specific event "Family Reunion 2016" but
generally these are ...
The MetaDataWorking Group, section 5.9 (face regions), is the best standard going forward for managing people tags. Right now Picasa, MS Photo Gallery and Fotobounce support this standard. Hopefully Adobe will jump on board since they are on the committee for this standard...
Try this command:
exiftool -d "%Y:%m:%d %H:%M:%S" -r -if "$FileModifyDate gt $DateTimeOriginal" -directory=/path/to/modified/ /path/to/source
This checks the FileModifyDate to see if it is greater than (string comparison) the DateTimeOriginal. If so, it will move it to /path/to/modified/
The -d (-dateFormat) option is needed because the ...
EXIF is mostly for technical details from the camera that created the picture, though there are some items such as GPS coordinates and date/time stamps that are appropriate to add such as in your case. IPTC is an older standard and XMP is the newest, most flexible standard for adding metadata.
A good place to start would be something like Adobe Bridge, ...
If I understood your question correctly, it might be the Toggle Auto setting of DigiKam.
With the Captions pane open, right-click on any one of the tags listed, go down to Toggle Auto and choose Parents.
Now when you check off a child tag, all of the other tags up the hierarchy also get checked.
(I wanted to send you a screenshot of the menu open but it's ...
I asked Amazon client support: it is not possible, but they "are glad to have received my request and have transmitted it to their team".
I also asked on the Amazon developper forum (not sure it is the best place), but so far no answer : https://forums.developer.amazon.com/questions/205330/retrieve-photo-tags-from-amazon-photos.html
There are multiple ways to do this, it depends on the type of photos (JPEG or RAW) and the desire to automate.
This shareware plugin seems to do what you want. When exporting your images, it assigns Mac OSX Finder labels that match the colour tags in Lightroom.
I haven't tried this myself, but the screenshots seem promising.
Manually convert LR tag to ...
From what I understand by reading your question it seems the main problem you have is of retrospective organisation of existing content incrementally and long term management of new inflowing content as time progresses.
From the looks of it what you really need is a digital asset management software (DAM is what it is called, don't ask me why.. maybe a ...
I was looking for something similar back in 2011-2012 (without the tagging capabilities) so this answer may not be the most up to date with today's new technologies.
The setup for this requires a lot of technical know-how and you will need to do your own research on what features of Amahi you want and don't want. This is not for someone who ...
Where are the synonyms being stored in the exported images?
In general on export Lr is gonna write all the keywords and synonyms into a flat list. IPTC provides for keywords, and that's it. Keyword hierarchies are actually stored elsewhere in the XMP metadata, and not all applications can even read them.
I'd wanna look at the XMP in the exported file, but ...
You can filter photos without a keyword in Bidge:
Navigate to the folder that has the photos with and without keywords.
Go to the Filter panel. If it's not shown, go to Window → Filter panel.
Click on No Keywords:
If your photos without keywords are spread out over multiple folders, you can go to the parent folder, enable Show Items from Subfolders and ...
The XMP files created by Lightroom seems to follow the MWG description (website currently down), as it contains this link to describe its content :
I took a random XMP file from one of my picture containing a recognized person : the part mwg-rs:Region is structured as follows :
You can customize the Metadata panel to show the Max Aperture tag. In the Metadata panel, click "Customize" at the bottom. Select "Max Aperture" under the "Camera Info" section, and that tag will now display in the panel.
JPEG, TIFF, PSD, and other file formats can include numerous types of standards, so as long as your software can be written to detect and parse these standards, you should be able to extract the information you need.
Some of the standards that programs use to store meta data on images include:
IPTC Core & Extension
If you are using Windows Photo Gallery (WPG), the "People Tags" are stored within the file as XMP Metadata using the Microsoft People Tag Schema. I you wish to move to another format, check out my blog post on the subject: Converting and Exporting Windows Photo Gallery People Tags. Among the apps which can read WPG People Tags are Photo Supreme and Digikam.
Photo Station for DSM (Synology NAS operating system) supports XMP Regions for tagging people (names), which is the same as for Windows Live Photo Gallery:
"the Supports people tags from Windows Live Photo Gallery"
Picasa will write face data to JPG EXIF, you just need to enable the option under TOOLS | OPTIONS | NAME TAGS | STORE NAME TAGS IN PHOTO.
Only problem is that it won't go back and update all your photos. You need to change each photo and save for the data to be written. I wrote a macro to change all filenames, then change back, then write all files to ...
when you use File/Export..., and scroll through the settings, there is a block about 'Metadata'. Set it to 'Include All Metadata'.
If you use a predefined Export filter, you might have to modify that filter to that setting - use File/Export..., chose that filter on the left, modify the setting, right click the filter name and chose 'Update with current ...
Here is a similar question, depending on what you want to do besides looking at the metadata it might be not really constructive to your workflow as mentioned in that answer.
Adobe Help shows you how it's done.
I dunno. I'm not sure if it's changed in v 8 but you're right, C1P's implementation of keywording was lame.
Media Pro does have hierarchical keywords, but it's an organizer, and seems to be languishing a bit at Phase One. There's a demo though, so why not try it yourself? It's horrid on the Mac, but maybe better on a PC.
I also liked Capture One's out of ...
If you don't have access to iPhoto (pre-OSX 10.10) or Photos (either of which should have come free with your machine, but apparently didn't), then a free package you may want to look into obtaining, assuming you don't want more sophisticated editing controls or a RAW converter, is Google's Picasa.
See Free program for editing pictures for a list of other ...
