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?
here is the script I wrote to bracketing a set of pictures when light changed.
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 1 (0.1s) if a<1 then let a=1 if b<1 then let b=1 c=c*100 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 e=f return
- You can test this version http://ewavr.nm.ru/hdk/for_test/ewavr-s2is-100f-150.zip. If video recording does not work, I shall make some more test versions. -Ewavr 11:22, 21 November 2007 (UTC)
- I am sorry to tell that this ewavr-s2is-100f-150.zip version still cannot work out in video in my S2 IS as well as the script command "get_tv" does not return me the exposure information... Jocewang 13:24, 21 November 2007 (UTC)
