@reyalp - you are right , I have tested it on G12 and it works
But it isn't working with BC script (don't know if it the cause or o haven't find the exect values )

@waterwings - can u confirm it isn't the custom fw /script ?

it mention that it is not supported yet in LUA
Oops you're right. It just sets the propcase, so in Lua you can just use set_prop. Something like
Code: [Select]
!mc:cmdwait('call set_prop(require("propcase").RESOLUTION,0)')
would set the largest size. Note above is off the top of my head, not actually tested.

I'm sorry, I don't know what this is referring to.

we continue to work on the system

we found that by using 3 tennis ball  hung with wire  we get nice calibration
first we need to zoom as much as possible and than calibrate.

Another issue that came up, is Lens distortion, after all it is cheap cameras  :(

I see you've already posted over there, but for the benefit future readers, this issue is discussed over in mphx thread: http://chdk.setepontos.com/index.php?topic=11667.msg117482#msg117482

Current 1.3 releases already have that "fix".

@ srsa_4c - I am using custom ROM prepared by WATERWINGS with remote shoot and BC remote (you are welcome to read earlier posts on this thread to learn about this custom rom)

@ Waterwings, Hope you have the time to recompile new FW with zoom distortion patch

Okay, if your build is earlier than rev. 3586 (21 / August), please make some test shots in a few zoom positions (wide angle, mid1, mid2, tele) for later comparison. "mphx" claims that the fix is not effective.

edit: use set_zoom for the test shots, not the zoom lever.

The required code is a standard part of the 1.3.0 release of CHDK and has been for some time. 

It does require a build option to be enabled (CAM_ALLOWS_USB_PORT_FORCING) and a small code change to the kbd.c file for each camera so it has only been enabled on three cameras so far (  A1200,  D10,  A2500 ).

To use it requires a one line addition to your script.  See :  usb_force_active()
