I cant seem to find the answer anywhere. I have a UK 450D on version 1.1.0 I want to increase the ISO for 3200 and 6400 - just to see how they come out. Some people say: "You have to set it in the custom functions, set ISO exspension to on. " and then some people say "it will be in custom functions, usually something like "ISO expanding" and you'll have to change it to "Allow". Then it will say H1 (ISO 3200) and then H2 (ISO 6400) instead if literally saying ISO 3200, ISO 6400." But I cant see these functions on the custom menu. All I have is: Exposure Level Increments - 1/3 Flash Sync Speed in AV mode- Auto Long exp. noise reduction- OFF High ISO speed noise reduction- ON - when shooting 1600 ISO in low light Highlight tone priority - Diasble Auto lighting optimizer - Enable AF-Assist beam firing - Enable AF during Live View - Disable Mirror Lock-up - Disable Shutter AE Lock - AF/AE Lock SET button when shooting - normal LCD display when power on - Display add original decision data - off Any thoughts on how I get the large ISOs? Thanks Joe
