Thanks Ian. Let me help you if I can by expanding with what I know.
I've been looking at the data you can get out of iView to try and do some XSL on it to get usable CSV and Excel files. There's a standard format for data items made up of date and time and guess what? Yep, iView doesn't follow it! While that's a minor issue for my XSL it did lead me look at all the dates within iView, including Capture Date.
This may or may not actually be the case. I spent days trying to get iMatch to put information into the IPTC date and time created fields. It wasn't the software which was acting perfectly. Rather the problem was the underlying Regional date and time setting for windows. I had to change these to get the format right.
From looking at a selection of my images the capture date is when the image was taken, limited to the accuracy of the clock in your camera. The date created field is when the file is created on a computer. The modified date is updated when the file is changed, usually when the meta-data is changed, or for DNG's when the preview JPG is updated.
You can see these dates in the Info panel in iView, with the Capture Date being in the Photo EXIF section.
Yes, and there is Date Created annotation field also which appears in the info panel. The Date Finder choses an explicitly set Date Created value. If not present the EXIF date created. If not present the File creation date.
I think that you may need to be very careful using what iView considers to be the Created date in your workflow as this won’t be the same as the capture date.
Agreed to a point. Most of the time it is and I back that up by setting the Date Created annotation explicitly.
I don't know what will happen for videos, but expect it to be the same.
Digital video downloaded off tape to AVI using SCLive (www.scenalyzer.com
) has EXIF information which matches the date from the camera. Each take or clip is split at the start/stop point and helps me to identify the correct sequencing of video if needed. Because the timestamp is recorded on the tape as well, if a clip should become damaged and this has happened once or twice due to DVD failure, then I can go directly to the correct point in the tape and recapture it to AVI.
At the moment I'm storing the date and time in yyyymmdd hh:mm:ss format in the title.
