I've been reading about the EXIF "standard", and it appears not quite to match up to that description!
One problem is that the tags are identified by number within the image file, and different applications attach different descriptions to these numbers. What seems clear is that there are three distinct date and time tags (with fractions of seconds in separate tags to go with them): taking one set of names, DateTimeOriginal is intended to denote the date of creation of the original object, DateTimeDigitized is for literally that, the date this digital copy was first made of the object, and DateTime is the date the file in which the image is contained was last changed. Shotwell is built around the idea of "Events", grouping images together by the date on which they (appear to have) occurred, so it's logical that DateTimeOriginal should take precedence. If this is absent, then DateTimeDigitized should be used, as this denotes an "event" in this image's history, and would tend to group images together in a chronological sequence (as a length of 35mm still film is scanned in). My scanner uses DateTime only, and it would be helpful if this could be picked up in the absence of the other two, and finally there's the operating system's creation date for the file - which is all you'll get (for example) in a BMP file. When I first got my scanner I used it to save the files in BMP format at maximum resolution, reasoning that this would include all the information the scanner could get from the image, but as my primary interest at that stage was the creation of some sort of index of all my old negatives I cut back the resolution and reverted to JPG to get the job done in a reasonable time without taking over all my hard disc space. Promising images can be re-scanned in a higher resolution. Is there any particular reason why you don't support BMP? I've started converting them to JPG so as to be able to get Shotwell to see them, but this is a tiresome chore, and takes up more disc space.
