While looking at the metadata of photos I am working with, I have noticed that identical photos in every single aspect of pertinent metadata (lense, focal, other various exif data) happens to have a slight file size discrepency.  For instance, a dscf2001 has a file size of 752kbs and the duplicate dscf2001 has the file size of 732kbs.  These photos have not been altered in any manner. 


This situation happens with a large portion of my duplicate photos.  One photo's file size is slightly bigger or smaller than the other photo that is the identical version in every single aspect minus the slight file size difference.  Is this a math situation?  If I open with another program will these photos appear as the same file size?
