Hi thanks msl,
can I do it in CHDK using C language as well?
Is it a precondition that I have to half press first? This would mean the focus is locked as well?
With digital DSLR (like e.g. Nikon D5500, Lumix GH3) I can set AE lock without half pressing the shutter.
With those cameras I can pan the cam and aim at an object and press the AE-lock button, AE is locked now.
Now I can pan back and focus a different object, half press to focus and full press to take a picture.
This I want to copy for my S110. So focus is on a different object than AE lock.
Here is what I want/need for my S110 in steps:
1. Pan the cam to object A, press 'function' (or other) button --> AE gets locked
2. Pan the camera back, aim a different object B, half press the shutter to focus object B
3. Full press to take a picture of object B
4. AE lock should be unlocked now
I want to develop this using CHDK an C language, can it be done?
