Yep, I was wrong. By the way (maybe this will be helpful for other users) I'll try to follow this tutorial:

I have another question which is more practical...
Canon sx20 gives the possibility to select the power of flash and CHDK gives it too.
The power could be set at low, middle or strong.
Nevertheless, I don't understand how to obtain the same power of a shot in which flash is automatically managed by the camera. I will explain the problem with an example:
The following shots were taken in a room with little light; the wall was about 1,5meters far.
- Shot 1:
http://imageshack.us/photo/my-images/838/img0229cu.jpg/Mode Av; Av 2.8; Tv 1/60; ISO 200; Flash popped up;
In mode Av it is the camera that manages the power of flash. I only set Av and ISO and camera selected Tv and flash. It seems that it does 2 quick low flashes.
However, I rarely use Av or Tv modes.
I usually shot in Manual mode
- Shot 2:
http://imageshack.us/photo/my-images/190/img0230ru.jpg/Mode M; Av 2.8; Tv 1/60; ISO 200; Flash popped up @ LOW power;
In manual mode, setting everything as the previous shot, the low power flash results to be not enough.
Let's try to use the middle power.
Shot 3:
http://imageshack.us/photo/my-images/339/img0231qu.jpg/Mode M; Av 2.8; Tv 1/60; ISO 200; Flash popped up @ MIDDLE power;
The flash is definitely too powerful and the shot is unusable.
I wish chdk gave the possibility to set also a flash-power like the one used by the camera in the first shot; I also think that an automatic flash mode would be useful even in Manual mode (Ok, I want to set Av, Tv, flash On/Off and ISO level, but flash power and focus should be managed by camera if I prefer so).
Any advise about this task? Could it be a main chdk proposal?
