Unless you're a developer with experience in reverse engineering firmware and prepared to put a lot of time and effort in, you can't use CHDK on your camera. As you can see from the CHDK developers page, the SX540 HS is colour coded black, which means: Black - neither original firmware nor firmware dump is available or in other words, it's not even ...

The best way would be to shoot with intervalometer to your lowest true ISO (probably 100), expose them right and then later blend them in average mode. CHDK has an average blend for the RAW's or just do them later in PC. The result will be pretty much of a long exposure shot.

If they accept your application (which they usually do), you will be given a link to download the SDK for free. Canon also accepts applications from non-US residents through ...

Since you are talking about CHDK, I'll assume you are using a Canon camera. The software disc that shipped with your camera includes a program call EOS Utility that enables your camera and computer to communicate. Part of the functionality included in EOS Utility is the ability to shoot tethered. This allows you to adjust many settings in the camera using ...
