Table 7 is popular.
Table 5 has less
mid-tone contrast and
shows more isotope
takeup. Table 10 has
more mid-tone contrast
and reduces takeup
visibility on film.

Start with Table 10.
Higher tables have
increased brightness
and reduce isotope
takeup visibility on film.
Lower tables show more
takeup.

Typically the density is
set to 2.8 by the Siemens
host control software.
