Hello. I have Canon SX 200 IS. I want to adjust exposure. But I can't control, menu button around wheel in ubasic script.

The click command allows up ,down right and left button click.
But I want to turn wheel clockwise or anticlockwise in script.

And I can't set exposure without wheel.(Up down left right button.)

How can I control wheel in Ubasic?

For me to understand your previous post, yes.

I think that is the "jog wheel". In uBasic you can try "wheel_left" and "wheel_right" commands.

Code: [Select]


print "Preparing..."

click "up"
sleep 400

wheel_left
sleep 400

wheel_left
sleep 400
wheel_left
sleep 400
wheel_left
sleep 400

wheel_left
sleep 400
wheel_left
sleep 400
wheel_left
sleep 400
wheel_left
sleep 400
wheel_left
sleep 400

print "Shoot -2 exposure"

shoot

sleep 400
wheel_right
sleep 400
wheel_right
sleep 400
wheel_right
sleep 400
wheel_right
sleep 400

sleep 400

print "Shoot 0 exposure"

shoot

As I understand, you might be better off using bracketing. See Manual Page 11 and 49.

Another option to do this is using a raw/DNG-File and applying different exposure settings on your computer (e.g. using "ufraw") in order to create HDRs. The latter has the advantage that you do not need a tripod or align several images afterwards.

First thank you m*sh.

I want to 3 continious different shoots(-2 ev, 0 ev and +2 ev) not using tripod. And not using raw format.
(I want jpeg file format)

I saw manual, (fulll manual) don't find needed information.

jogdial control should work on this camera, but it would make more sense to control exposure directly in the script, or use bracketing in continuous mode.
