I have difficulity in make good use of the CHDK in my S2 IS camera. Two very useful functions are not working well: 1. when I update the CHDK to pre14.grand148.md.cln.zsm-s2is-100f-119 or 120, I cannot use video recoder (it will hang my camera), but pre14-s2is-100f-148 did work. 2. when it is in "alt" mold (try to run a script). I am writing a script try to get the exposure information in the Av mold by: [press "shoot_half"] [sleep 3000] [get_tv f] but always get the f value to 15 with different light condition. Anyone out here using S2 IS GM1.00F and working?
this is my program
rem Light Change Capture (from dark to bright)
@title Light Change Capture (Av Mode) @param a Number of Pics @default a 8 @param b exposure time differnce (in step) @default b 1 @param c time wait for shoot half @default c 1000
if a<1 then let a=1 if b<1 then let b=1
print "Pics:"; a; " Step:"; b
click "shoot_half" sleep c get_tv e print "preset tv=",e
for s=1 to a
if s<a then gosub "cec" if (f-b)>=e then gosub "cap" else s=s-1
next s
end
rem check exposure change
- cec
click "shoot_half" sleep c get_tv f print "p=";e;" n=";f if f<e then e=f
return
rem capture one image
- cap
shoot print "Pics:"; s;"/";a; "Step:"; b e=f
return
end
