I have just installed CHDK onto my Ixy 900 is (Sd 800, Ixus 850) and am still getting use to using it.
So far to get long exposures to expose correctly i have been using trial and error....
When using long shutter overides is there a way to use the camera's internal light meter to judge correct exposures...? And can you lock the apeture in an Ixy 900 is?
Sorry if this is a stupid question but i can't work it out for the life of me...
