I'm wondering if anyone on this forum might be able to give me 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.
Say I have the dial set to 300. I can turn the dial down and the LCD screen shows the ISO reducing but only down as far as ISO 320. After that, I can keep turning the dial down to 200, 100 or less but the display still shows the ISO as being 320. If I then take a pic and look at the picture properties on the PC, they never show values less than 320 either
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? Has anyone else come across this problem with their G12?
Would be very grateful for advice, I'm trying to decide if it is me at fault or if the camera is faulty.
Thanks for your advice but in fact I have now fixed this problem. It turns out that I needed to turn off Dynamic Range correction, and now I can use whatever ISO I want. I had forgotten that I had posted this here otherwsie I would have updated sooner. Thank you for bothering to help me though, much appreciated.
