If the photographer
did any post-processing (e.g., color correction, cropping, retouching) in
a program like Photoshop, the file??™s date will reflect the last time the file was
saved, not when the photo was originally shot. Also, file dates and times are
typically set when a digital camera saves photos to its memory card, not necessarily
when the photos are taken. (The discrepancy occurs because many
high-end cameras hold the shots in memory before saving them.)
But aren??™t you lucky you live in an enlightened age of obsessive photographers
and feature-laden gadgets? Embedded in each digital photo is a goldmine
of information stored by the camera as part of the EXIF (EXchangeable
Image File) format used in .jpg files, .tif files, and raw formats like Nikon??™s
.nef files. EXIF data includes the date and time the photo was taken, the
camera settings used (f-stop, exposure, metering mode), the photographer??™s
name (sometimes), and the dimensions of the image. If the camera supports
it, even GPS data indicating the exact geographical location of the camera
when the photo was shot can be included.
To view EXIF data for a single photo, highlight the image file in Windows
Explorer, and then stretch the Details pane until it looks like Figure 4-18.
If you don??™t see a Details pane, click the Organize drop-down and select
Layout ??? Details Pane.

Of course, you won??™t find EXIF data in scans of film, nor in
digital photos that were modified by software that doesn??™t
support the format.
