Hello Aspirant,

Scanner software adds features to correct faults in a scan, e.g., dust or moire. it reduces the size of photograph. The platen tends to ensure that the scan is flat (no curls in the document) and lighting is even and consistent.  Other than that it is effectively the same.  As we reduce the size of photo it saves our memory  and data to send it. now , if we talk about normal photograph it has more size so it requires more memory space and data to send.
