I've tried to enable long exposure times, but the maximum I get is the stock 15 seconds.Extra Photo Ops, Disable Overrides is DisabledOverride Shutter Speed is 2048 (the biggest number I could find)Value factor is 1 (the only other option is Off)When I go into Tv mode (on the dial), I see a Tv value of 2048 on the display, but the shutter speed maxes out at 15"I must be missing something.
Quote from: Markeight on 06 / August / 2009, 05:23:21The Manual mode give me the possibility to bring the exposure up to 15 second, but i'd like to have more.In chdk "Extra photo operation" i can set the Aperture up to 28.40 sec, but than my camera still uses the 15 second on the manual mode.No, with CHDK you can set up & use up to 64s on your SD750.You can either choose one of the values in Override shutter speed - or you can use this setting in combination with the next menu item, the Value factor, for this set Shutterspeed enum type to [Factor]...Sample: Override shutter speed [23] Value factor [1]Shutterspeed enum type [Factor]gives you 23 x 1 = 23 s exposure time.The Canon OSD don't know anything about the CHDK overrides, it only shows values from the internal Canon list,so on exposure times beyond the Canon limit of 15s the Canon OSD will always show "15s"...You can enable the additional CHDK OSD values from the OSD (Misc...) menu to see the "real" override values...

After the 60 second exposure, there is a 60 second "busy" period. Any idea what the camera is doing during the second minute?
