It really shouldn't take much more than the snippet I posted earlier, something like
Code: [Select]
function my_shoot()
 <snip>
end
The kap_uav.lua script does something similiar, (lines 788 to 830) except that it pushes Tv up to a user defined max value and then adjusts Av and/or Sv so that the overall exposure stays correct.

had a few moment and had to change the snippet to: "if get_tv96() <" to do what I wanted (limit lowest speed, not highest)
thanks for this helpful snippet.....getting back to the drawing board now.

well, I can only say thank you very much reyalp. this snippet is exacly what i wanted! :lol

I am in the process of building a test rig and script to sort out what would be my ideal exposure limits..at this moment it looks like 1.6sec@iso400 or similar but better 3.2@iso200 is a good starting point.
