I’m wondering if anyone on this forum might be able to give a complete novice some advice. I bought a Canon G12 a while back in order to learn more about aperture’s, shutter speeds etc and how to manually take better pictures.
My problem is I seem to be unable to obtain ISO values of less than 320 on the G12. It doesn’t matter if I am in program mode, Manual mode, Av or TV, the lowest ISO setting the camera will allow is 320. It will let me dial any value above this but as soon as I try to dial down it stops at 320 and stays there. I can dial in aperture and shutter speeds that give plenty of light, in an outdoor setting on a bright day, and it still will not allow me to select a lower ISO. I’m obviously doing something really stupid but I don’t know what.
Can anybody tell me what I’m doing wrong?
