Is there an EXIF standard for tagging people in photographs?

Question

There are a number of websites that let you tag people in photos, such as Facebook and now flickr, but is there an EXIF standard for tagging who is in a photo, and where they are?

Answer

There is not. IPTC, another image metadata standard, also does not contain a "People" field. There's a Contact field, but that is used for contact information for the photographer.

Most people I know will store people as keywords. The main debate is whether or not to include spaces (would a photo of me be tagged as aaronhockley or as "aaron hockley"?). I don't use spaces since that simplifies things at times, but it's pretty subjective. I think the main thing is consistency... pick one method and stick to it.

How to shift EXIF date/time created by time in days, hours, minutes?

Question

I have two camera bodies, I was shooting while on vacation, when I downloaded the photos to lightroom, one body was set to the correct date/time, the other was off by 722 days, 4 hours, 32 minutes.

Is there a tool available that can help me fix the date/time so that they appear in sequence while browsing my lightroom library? I'd like for them to be as close to the right time.

I was able to adjust created year, month, date, but it doesn't appear lightroom will allow me to adjust increments (only hour increments).

Many thanks if you can help me in this task!

Answer

I just found the answer.

Lightroom will change the date/time easily by selecting the image you know the proper time for, then select all others to be changed - similar to how develop sync settings works.

After the selection is made, click

Metadata -> Edit Capture Time

Select Change to a specified date and time

Enter the proper date and time for that one image, Lightroom will adjust all other selected images based on the proper time you define you enter.
