<p>
Return the base offset.
<p>
TIFF standard format uses byte offsets which are always relative to the start of the TIFF file, i.e., relative to the start of the TIFF image header. In this case, the base offset is 0. However, some camera vendors encode their makernotes in TIFF IFDs using offsets relative to (somewhere near) the start of the makernote data. In this case, base offset added to the start of the TIFF image header points to the basis for such makernote offsets. </td>

Different create functions may use different lookup tables, so that makernotes can independently use their own factory function and lookup table, which can be defined together with the makernote implementation. </td>
