it does not work for me...
i could not manage to override the exposure. the OSD shows me my overrided exposure time. but just when i press the shot-button it switches to the original one. (it does not matter if i am in P, Tv, Av or M mode)
None of the overrides work, TV, AV, ISO.. all show up in the OSD but when you press the button the TV-value shows original and the rest show the overrided value but none is affected by the overrides. Could it be similar problem?: http://chdk.setepontos.com/index.php/topic,2654.msg24845.html#msg24845
I do not have an SX110....(Me, I'm the SX1 IS porter)...but what you describe points out that
a) either not yet all "adresses" are properly ported in your "build" for the SX110 (<-- "ALL" Overrides do not work!)
b) or eventually you have a wrong "general" button: --> First entry on "Extra Photo Operations" needs to be set to DISABLED (= do not "disable Overrides"!) :-) If it is set to "ON" it WILL disable the overrides..
---------------
Long Exposure: Don't know who is the "porter" of your thread....actually check, that the "Long Exposure" Parameter is also defined on the SX110 Section in "camera.h" file! Else - despite of "ported" code - long exposures are still not possible. (<-- made this experience myself) :-)
Hope this helps you, guys....
