Sensor speed ( Sv)
get_iso x uBasic
x = get_iso() Lua
set_iso x uBasic
set_iso(x) Lua
Retrieves and sets the ISO speed (Sv) index (Table 5-3). The index values > 0 are
mapped to ISO values of 50 and above. The index values –1 and 0 have a spe-
cial meaning and stand for HiISO and AutoISO.
get_iso_mode x uBasic
x = get_iso_mode() Lua
set_iso_mode x uBasic
set_iso_mode(x) Lua
Retrieves and sets the ISO mode
(–1 = HiISO, 0 = AutoISO, 50, 100, 200, 400, 800).
get_iso_real x uBasic
x = get_iso_real() Lua
set_iso_real x uBasic
set_iso_real(x) Lua
Retrieves and sets the real ISO value. This is the real value used to control the
sensor.
get_iso_market x uBasic
get_iso_market(x) Lua
Retrieves the “marketing” ISO value—the value shown on the display. This
value is higher than the true ISO value (section 4.3.1).
get_sv96 x uBasic
x = get_sv96() Lua
set_sv96 x uBasic
set_sv96(x) Lua
Retrieves and sets the internal sensor speed (Sv) with 96 units per stop.

–1 – HiISO
0 – AutoISO
