Hi there,
I would like to disable the ND filter in the following script on my SX100IS. Is this possible?
Thanks!
@title Sunset4
rem Script to shoot time-lapse videos of sunsets
rem v. 4, Fbonomi apr 30th 2008
rem Released under GPL
@param a Delay (sec)
@default a 10
@param b Limit Tv
@default b -414
rem (-414=20 sec; -384=15 sec; -320=10 sec; -224=5 sec.)
@param c Default Sv
@default c 480
rem (480=160)
@param d Limit Sv
@default d 776
rem (776=1250 ISO; 960=5000)
@param e Guess mode limit
@default e -200
@param f Slope in guess mode
@default f 5

rem initialize guess mode value
x=e
rem get start Tv

rem picture counter

press "shoot_half"

rem resulting Tv would be:

if T>e then
rem normal mode, shoot with calculated Tv and default Sc

if x>b then
rem we are in dark, but exposure is not too long
rem normal mode, shoot with guessed Tv and default Sc

Y=c
print "Mode: Guess"
else
rem we are in very dark area, we want to avoid too long exposures
rem shoot with maximum allowed time (b) and
rem adjust Sv accordingly

rem BUT check we don't go in too high ISO!
if Y>d then

endif

rem we can now shoot
sleep 100
