Not that I am aware of. Your using vbGalley and php exif function with a nikon.
Your other example is Photopost Pro which uses jhead not php exif and a canon camera.
Both functions that I see just strip the info the camera writes to the photo and inserts it into the database for display. This is more so probally an issue of how your camera model writes the exif data than anything else. Your Nikon which is probally a very expensive efficient model writes exif in true values and that canon sureshot which is a cheap model probally writes data in short hand values. Probally the difference in comparing a samsung tv versus an rca tv.
