hdr timelapse script for a720is ?

hello everyone !
i have tried to search for a few hours and cannot find where to start editing my ult_intrvl.bas script
to take 3-5 shots  for this camera
for one shot this script works fine
cannot find any scripts for exposure bracketing tho, prob because it works default with chdk.
figured i could add a parm for tv , # of shots 3-6 and then add that into the
Code: [Select]
:interval
  if p>0 then gosub "pause"
  for n=2 to c
  sleep t
  print "Shot", n, "of", c
  shoot
  next n
  if g=1 then goto "interval" else endbut i cannot find anything for bracketing that works for the a720is
even tried setting the camera up for bracketing  with its custom timer to take the 3 shots  and  wont work with the script
anyone able to point me in the correct direction ?

 :blink: never mind  it works  with bracketing with the self timer  the before shot delay  was throwing me off  and i didnt fully wait until the full time had passed untill next shot

having it all in one script tho would be nicer

Checkout the following, you can have Tv, focus or Tv and focus-bracketing :-

http://stereo.jpn.org/eng/sdm/tlapse2.htm

This tells you how to exposure-blend a folder of images by simply entering the number of images in your bracketing sequence:
