Tweaking a Camera to Suit a Hobby New York Times
“I got a picture when the balloon was at about 87,000 feet above northeast Iowa,” he said. “We could see Lake Michigan. That was pretty impressive.”
To take these photos, Mr. Lilja, of Cedar Falls, packed his Canon A570is with a GPS transmitter in a cushioned box (and attached his phone number in case the GPS failed). He chose that particular point-and-shoot camera because a group of programmers from around the world had created software that gave photo hobbyists like him the ability to change the way Canon intended the camera to operate.
It is called the Canon Hack Development Kit (or C.H.D.K. for short). Mr. Lilja used it to reprogram his camera to snap one shot every 15 seconds on its journey into the stratosphere . The software has allowed photographers using more than 50 models of Canon PowerShot cameras to reprogram the time lapse instructions to record construction projects or to use motion-sensing programs to capture animals in the deep woods. It can also be used to alter the camera’s exposure control to produce imaginative images in difficult lighting. (The hacks do not work with the more expensive D.S.L.R. cameras). Development of the hack kit began as a volunteer project about three years ago. It can be customized by adding programs written in “ubasic” or “lua,” two common languages that are fairly easy for programmers. Many C.H.D.K. users also swap scripts with each other and modify the work of others.
But the hacking kit works only with Canon cameras, one of the most popular brands. Apparently, no such extensive project exists for hacking the software that runs Nikon, Sony , Panasonic or other popular cameras.
The Canon hack kit is good at setting up a camera to perform simple, repetitive tasks.
Julien Quénard, an amateur photographer and bird watcher in Arrest, France, programmed his Canon PowerShot A540 to constantly watch for birds, modifying a motion-detection script originally written by a developer who referred to himself among fellow camera hackers only as Fudgey. When the birds move into the frame, the camera quickly focuses and then takes a sequence of four pictures. He keeps the camera pointed at the bird feeder, but he has also found that the redstarts and flycatchers like one particular section of his garden. Mr. Quénard’s version uses the fastest shutter speed possible because the birds move quickly, and uses macro mode for close focus.
The camera’s new software leaves some tasks for him, however. “Each time, there are a few good pictures and hundreds for the trash,” he said. “I also need to crop most pictures for better framing.”
The C.H.D.K. developers pool their resources at chdk.wikia.com , a Web site that collects software contributions and shares the packages with other users. Any photographer can download software files free under an open-source license and copy it onto a flash memory card that normally holds photographs. The site offers a “ C.H.D.K. for Dummies” page with step-by-step instructions for loading the software into the camera. The C.H.D.K. software loads itself into the camera by taking advantage of the updating mechanism normally used by the manufacturer to install new software with bug fixes or new features. When a Canon camera is first turned on, the camera scans the flash memory card for updates to the camera’s software, often called firmware. The C.H.D.K. software is made to be temporary, though, and it can be removed by turning off the camera and deleting these files from the flash card. The C.H.D.K. Web site warns that something may go wrong in the process, potentially voiding the warranty, but several developers say there are no documented cases that it has ever happened.
Canon did not want to comment directly upon the C.H.D.K. project or whether it could harm the camera, saying only that untested software might “damage Canon equipment.”
Several contributors to the C.H.D.K. project suggest that many employees at Canon quietly support the project, either because they think it is cool or they guess that it will sell more cameras. Other programmers say they think Canon may lose some sales of more expensive models to users who can use the C.H.D.K. to add these features to the lower-priced cameras. But while C.H.D.K. can add some advanced features, it can not change the lens or increase the size of the sensor, the two factors that most influence a photograph’s quality.
“A good lens and a good sensor can’t be emulated by software,” says Francesco Bonomi, a programmer who works near Florence, Italy.
Mr. Bonomi, who experiments with taking photographs when there is very little light, has been rethinking the traditional solution of leaving the shutter open longer. Estimating how long to leave the shutter open is hard, so many photographers take a wide range of pictures, exposing the sensor for different amounts of time, a process often called “bracketing.”
“I don’t do actual bracketing.” Mr. Bonomi said. “That means five to seven exposures. What I have done is a few hundreds of exposures that are kind of short and then do a virtual bracketing. If I have 512 photos, each one that is two seconds, then I can add them up and get a virtual exposure of 1,024 seconds.”
Splitting the long exposure into hundreds of smaller ones avoids the problems that might occur when a car drives by and lights up a dark scene. Mr. Bonomi just discards the atypical images when adding together the results of all the short images.
But splitting the image can conflict with the way many point-and-shoot cameras store images in a compressed format known as JPEG. The compression algorithm saves space by omitting detail, which introduced errors into an application like Mr. Bonomi’s.
The C.H.D.K. solves this problem by reprogramming the camera to store all information without any compression in the raw format.
Mr. Bonomi also puts his Canon SD1100 on balloons to take high-altitude pictures of Italy. He is rewriting the software that measures the light available to improve the exposure of his pictures. His version will average the 100 or so measurements taken as the camera swings around under the balloon.
Rewriting this software requires careful attention to detail, he said.
“It’s a program that must run for two or three hours, making some critical decisions on its own. It can’t crash,” he said.
Crash? He was using programmers’ slang, he said to describe when the camera locks up because of a software error.
“If it crashes into the ground, that’s also bad,” he said.
But that is easier to handle with a bit of padding.

PowerShot A570?
On the Canon PowerShot A570, right below the lens and a little to the left. there is a button, I have read the manual a million times, and cannot find out what this does, what does it do?
It's the ring release button. It unlocks the ring around the lens so you can attach optional conversion lenses onto it.

How can I take a great shot of lightning with a canon powershot A570 IS?
I got a canon powershot A570 IS and I need to know how to take a good lightning shot.
Is it possible to take a quality shot with my current camera?
1. Find a place to put the camera. If you don't have a tripod, put on top of a table or something else outdoors that isn't moving.
2. This camera takes pictures up to 15 seconds long. Take a picture at ISO 80 and 15 seconds and see how it comes out. Are you doing this during the day or night? At night, you should be good. During the day, this might come out too bright so shorten the time.
3. Just keep taking pictures over and over facing the lighning until you get lucky.
That's the "brute force" way. The other way is to put it on a ISO or 200 and stand ready to take the picture when you see a lightning bolt.
How to take a good photos with Canon Powershot A570 IS ?
Hi,
I recently bought Canon A570 IS. I just dont know how to make a good picture in manual mode. All of them are so dark! When i doing in auto mode they looks cool but not as good as i seen on flickr when peoples doing a shot without flash light and they looks good.
And also... do i need to use zoom for macro mode ? Or just click the macro button ?
Thanks!
Let's go through you questions one at a time:
1) Manual mode
ANSWER: Manual mode without flash isn't as simple as just turning it to manual mode and shooting away. In manual mode, you must manually set the aperture and shutter speed. To do this
*Put the switch to M
*Push the lightning bolt button to turn off the flash
*Along the bottom, you get a shutter speed and aperture
*Adjust one variable, then push the +/- button to adjust the other variable.
* To adjust, just push ring on each side of "Func Set" button.
*The screen will show the effects of changing each variable, as long as your flash is off. When the screen is what you want, you can take a photo. It may be dark or black if you're settings will give you a dark photo.
* Use a tripod for a really slow speed or you'll get a blurry photo.
2) Macro mode:
ANSWER: Macro mode is done by pushing the flower button on the back. You can get closer if you are at the widest lens setting, which is what you should use for macro. Push the release to focus.
slow shutter + big appature = brighter picture
throw in the higher iso speed (film speed although virtual)setting and you can work in lower lighting levels with faster shutter speed
if you want to take macro pics just click the macro button
But first as one answerer mentioned leave all on auto, until you learn your camera better.
How do you upload pictures from a Canon powershot A570 to a computer?
My computer does not detect the device. I have installed Zoom Browser EX and Camera window. Please help!
Check your computer's USB drivers. Do other USB devices like a USB Drive or web cam work in your computer? If they don't, its probably a problem with your USB port / drivers.
How do you upload pictures from a Canon powershot a570 to a mac?
I plug it in but no device is detected...
what should I do?
Is the camera turned on when you plug it in?
If yes, can you see the camera in Finder?
If no, try connecting the camera into another computer to see if it works there.
If you have iPhoto, it should find the camera as soon as you connect it, if the camera is on.
Plug in the camera and the computer.
Launch iPhoto.
Turn on your camera.
You should now see a dialogue box to download your photos.
OK? Working?
My canon powershot A570 IS depletes batteries immediately?
I just used some Lithium energizer batteries and they lasted for weeks. Now every time I replace it with new batteries, it depletes them immediately and shuts down. New batteries always say "low battery" and then shuts down. Does anyone know why this is happening? Thanks
i think there are two reasons
1. maybe the battery not good conditions
2.maybe the camera creepage
I can't decide whether to buy a Canon SD1000 or the Canon Powershot A570 IS. Which is the better camera?
Also, is the format of the video recorded on these cameras able to be played on an Ipod? Is there really a difference between the factor that only one of these cameras has optical image stabilization? Can you tell a big enough difference with or without it?
Image stabilization on the A570 IS is pretty handy, but if I were you I'd look into the SD800IS, you lose a couple megapixels (that you probably wouldn't use) but gain image stabilization and a wide angle lens (useful for crowded indoor shots).
Optical Image stabilization makes a huge difference for the shot on the go, low light conditions, and in general it makes up for the natural shakiness of the human hand. You can tell there's a notable difference, the Canon IS line has been exeptional in their image stabilization.
Both the SD800IS and SD1000 save to video formats which can be viewed on an IPOD. I believe the A570 IS can but don't know, push comes to shove, you'd just have to buy or download a converter
Can I use a PNY 4 gig SDHC memory card with the Canon PowerShot A570 IS Digital Camera?
I was wanting to buy a regular 2 gig SD card for my new camera, but found a 4 gig SDHC card for just 10 bucks more. I have heard there are some compatability issues with SDHC card. Will I have a problem with this card for my camera?
According to the Canon website, the A570 IS supports the SD, SDHC, and MMC memory card standards.
SD: Secure Digital standard card supports capacities up to 2 GB.
SDHC: Secure Digital High Capacity currently supports capacities up to 32 GB.
MMC: MultiMedia Card supports capacities up to 1 GB.
If the PNY card doesn't work, it's because it's off from the standard somehow. But the Canon A570 IS will accept an SDHC card and is supposed to work with it.
Where can I buy a Canon Powershot A570 in Metro Manila, Philippines?
I'm having a hard time finding it online, Brand new or second hand is ok- thanks in advance!
What are some of the best/expensive swivel + bounce head slave flash compatible with the canon powershot A570?
I need a slave flash that will have a bounce head while attached to the camera by tripod slave flash adaptor that will also be able to use diffusers. This must also be able to swivel and should have multiple power levels. I would like to get one with a quick recycle time. at the moment i cant find many and mostly need as may suggestions as possible.
What you want to do is hilarious--you're asking for a pro-level flash for a point and shoot camera.
Still, I think I know what you want--try the Phoenix Digital Slave Flash for Analog & Digital Cameras.
If you go to http://www.porters.com , it is item 120457.
You'll probably have to look for a third party diffuser.
