I think step number one is to find something more interesting than crumbs on your keyboard to shoot. And I don't mean that in a flippant way. Get away from the computer and stop taking test shots — start taking real photographs which you find interesting. Take those photographs back and do exactly what you've been doing: play around and make them look as ...

As you can see right on the main CHDK wiki - "Temporary – No permanent changes are made to the camera." You also can find very detailed information in the FAQ here. Basically - Yes you are hacking your camera. So things can happen that the original manufacturer did not intend(if this wasn't true, you wouldn't want it anyways). But the chances of any ...

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 ...

I've had no problems with CHDK on a A430 doing timelapses over a day or two. I've also used it to enable raw capture. I would concur with cmason's use of the phrase "alternate firmware". It's still firmware, it just doesn't replace the factory firmware. There are warnings on the CHDK website indicating that CHDK may make it possible for you to request ...

CHDK is alternate firmware that is loaded on your SD card. It does not alter the factory firmware at all. When you start up your camera it loads this alternate firmware. When you are done with it, or don't care for it, simply put in an empty SD card and turn off/on your camera and it loads the factory firmware, just the way you left it.

Apparently there is a more recent build of CHDK for this type of camera that can be found on the forums: http://chdk.setepontos.com/index.php?topic=7864.0 Downloaded & installed it and works fine now. The newly generated DNGs are free of dead/stuck pixels now...

You can encourage development by providing developers with a firmware dump. The following resources may be helpful. CHDK Wiki: Obtaining a firmware dump. CHDK Wiki: Canon Basic/Scripts/Dumper CHDK Wiki: Udumper

http://www.pentaxforums.com/forums/6-pentax-dslr-discussion/250555-resurrecting-pentax-firmware-hacking-35.html There is a guy who named himself "shodan", putting effort into completely hacking the current Pentax DSLR firmwares... here is the link to his github-page: https://github.com/i-am-shodan/PHDK

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. BTW: Blending many shots cancels noise because it's arbitrary (random), the more ...

So, good news and bad news. Good news is that you can replace the embedded JPEG with ExifTool (as shown in Can I embed existing JPEG's into DNG's as a preview?). Or, you can use dcraw -e to simply extract the preview to look at it separately. The bad news is: this is extremely unlikely that Preview will fall back to doing its own demosaicing / RAW ...

There are some good tips about installing CHDK on a Mac listed here : CHDK FAQ : Mac Also, at the top of that page is a link to a utility called STICK that will do the complete install for you on a Mac, Windows, or Linux computer.

Canon publishes an SDK for interfacing with their EOS cameras called EDSDK. In order to use it, you must live in the US, register through their website and fill out an application. 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 ...
