Finder displaying different information for the same file.

Hi to all

If possible could someone explain an issue that has pestered me for a while but has just got more confusing just now.

I am currently organising my huge photo library and in this process a problem arises on many occasions which has baffled me but more importantly slows the workflow considerably. The issue is the 'Date Created' and 'Date Modified' columns on many occasion show the incorrect info in Finder. In fact there are a couple of issue I don't understand and I wondered if it is something as simple as a setting somewhere?

To explain, when I open a folder of files in Finder, in this instance a folder of skiing photos the 'Date Created' and 'date modified' are the same. Which straight away they shouldn't be. I would expect the 'Date Modified' being different as generally I group photos from different devices into one folder so logically the 'DM' should be the date I imported into the folder, or if I modify a file in some way, but the 'DC' should show the date (and time) the photo was taken. This should remain unchanged. But it doesn't in finder, it shows the 'Date Modified' for both!! Strangely when I import into a photo application (I still use iPhoto/Aperture and also Photos) it shows the correct date and time stamp!

But today I found something even stranger. When I searched a photo in spotlight, Finder showed the correct date and time that the photo was taken, but the 'Date Modified' was the same as the 'Date Created', but the same pic in its folder in Finder showed what I normally see which is usually incorrect. It seems that somehow Finder is looking in a different EXIF field depending on how you search.

Using an EXIF editor I can see the actual 'Date Created' in a number of fields but finder when accessed normally doesn't display it. There is one field 'fileModifyDate' which seems to be the field it chooses. Which of course logically it should only choose for the 'Date Modified' column, not for 'Date Created'.

Is this a setting that I can change or is this a glitch?
