CHDK HANDBUCH PDF

Installed a Allbest version for A, set up to take raw pic's with it. But I have yet to process any files since it is a bit confusing what to do to read the raw files. Canon-hack Development Kit CHDK During the second half of , programmer 'VitalyB' studied a disassembly of the firmware update for an ixus camera in order to understand the Canon firmware-update procedure. This is code that you can install on your cameras SD memory card that allows you to access extra features that are normally only available on very expensive professional cameras.

Note: it will not run on DSLR cameras. These new features are accessed through CHDK-specific menus, rather than the default camera menus. As CHDK is continually evolving, new features are added as they are developed. Updating occasionally will ensure you have all the latest features for your camera.

Firstly, by the skill, persistence, and generosity of the developers, and other contributors to the CHDK project. Secondly, in the same way that your computer hardware runs an operating system, such as Windows, Mac OS, or Linux, your Canon camera also has an operating system in it. CHDK is simply software. Just like a computer, when the camera is turned off all the software disappears from memory until it is turned on again and CHDK is reloaded.

Also like some software, there is an option to automatically start CHDK when the camera starts "booting". A card reader is used to connect the SD flash card to your computer. Once connected, the SD flash card appears like any other hard drive on the computer. Your printer may contain a usable card reader. Card readers are fairly inexpensive, and can simplify transferring of files, and thus files can be transferred via USB. The information offered is for experimental application.

CHDK is experimental! CHDK comes with no warranty for any use - use it at your own risk. Before downloading and using the CHDK software, careful consideration should be given to the following:. The short answer: It is unlikely, but theoretically possible. CHDK is created by reverse engineering an undocumented system that directly controls the hardware.

Because of this, it is impossible to be certain that it is completely safe. There have been no confirmed reports of CHDK damaging a camera, and both the original firmware and the CHDK developers use safeguards to prevent situations where this could happen.

For example, it is possible to command the lens hardware to move when the lens is closed. It is also possible to move lens hardware beyond limits allowed by Canon's firmware, using scripts, or overrides. Since CHDK is never intended to write directly to internal flash, it would take an extremely unlikely sequence of events for this to happen. It is worth noting that neither of these cases has resulted in actual damage, and both would require direct input from the user.

If you are concerned about this, the risk can be minimized by avoiding untested developmental builds such as test builds posted on the forum and being selective about what scripts you run.

One more thing: There are tens of thousands of satisfied users all around the world enjoying the benefits of CHDK. See also GPL license information below. Once CHDK is installed, you will need to start it on your camera.

As explained earlier, CHDK does not actually change your firmware, so it must be started each time the camera runs. Both methods are fully described on the Prepare your SD card wiki page.

Use this method to load CHDK once, manually. If this method is used, CHDK will be unloaded when the camera is powered off, and you will need to repeat the steps each time you want to use it.

Despite using the Canon Firmware update menu, it does not update the firmware. Start the camera in playback mode. On cameras that with a distinct PLAY button usually a blue triangle use that to power the camera on instead of the power button. SET - Fig. See Prepare your SD card for details.

After the card is prepared, CHDK will load automatically when the camera starts if the card is locked. To disable CHDK temporarily, just unlock the card. After the splash screen shows, CHDK is running in the background.

Some features are enabled by default, for example, the battery and memory indicators. However, most features are inactive by default. Pressing the shutter button half or full after the camera is started also switches to record mode. For example, pressing the FUNC. If it is not, please feel free to update the information on that page. You can now use the camera to take photos or video, and its operation will be changed by the options you set in CHDK And one final point: you must also switch the camera from playback mode to shooting mode to take pictures.

Use the Directional buttons to navigate the Menus. SET button will select the highlighted menu option. Pressing the DISP. Pressing the MENU button will exit the current operation. When entering numeric values in menu item fields, your camera's zoom lever can be used to move between input digits. It is not necessary to press the right arrow button times to set a value of Simply press the zoom lever to the left twice and then the right arrow button once.

For cameras without a zoom lever, the DISP button can be used instead. These are specifically those functions related to exposure and focus settings. For many cameras, having the camera configured with Servo AF enabled can cause overrides to be ignored. Also, if your camera has a hot shoe for an external flash unit, anything in that hot shoe bracket like a cover, bubble level, or external flash unit can cause CHDK overrides to be ignored.

Also remember to uncheck the " Disable Overrides on Startup " menu item if you want to retain your override settings after a restart. Please note that the actual speeds available are dependent on the camera used and other conditions such as the aperture setting. Note that Tv override is enabled when the selector box beside the Value field is enabled. Simply select the desired setting and the camera will use that setting in all auto and manual modes.

Please note that the actual aperture values available may depend on the camera's construction and zoom position. Select the desired ISO setting and the camera will use that setting in all auto and manual modes. Enter the focus distance in mm from the lens. Depending on camera, you may need to activate AF lock for subject distance override to work. Infinity is immediately selected by pressing the UP key, and for Hyperfocal adjustment based on current F-stop and zoom focal length, press the DOWN key.

Enables simple and fast adjustment of exposure compensation EV. For cameras with a rotary jog dial, rotating the jog dial while holding the Shutter button in the half press position will cause the EV to increase or decrease depending on the jog dial direction. When selected, enables automatic flash exposure control when the camera is set in manual mode for Tv, Sv, Av. Also allows manual compensation of flash exposure.

Useful for using electronic "through the lens" eTTL exposure control when using external or internal flash while other setting are locked manually. This feature is used for optional control over camera flash output, allowing give 3 separate steps in flash output power.

Will override the flash power setting when then camera exposure control decides to fire the flash - especially if the camera is setup to force the flash to fire. Because there is no preflash with manual flash, force manual flash can be used to advantage when using slave flash equipment. Pics thanks to Walqas. Cameras with a hot shot for use with an external flash can detect the presence of any device attached to the hot shoe. If there is something in the hot shoe. This menu item allows the camera to either ignore the hot shoe Empty option or assume there is always something in the hot shoe In use option.

When the camera detects a really bright scene, it will swing the ND filter inline with the lens and sensor. This is primarily used to allow the camera to shoot at a lower shutter speed, useful in a bright light shooting situation where some motion blur may be desirable fireworks or where the scene is so bright that the camera must shoot outside of its normal range. With the ND filter in, the camera can select a slower shutter speed without over-exposing the entire scene.

In means the ND filter is swung in. Out means the ND filter is kept out. Dark Frame Subtraction is a function used to reduce the effects of sensor noise - especially useful when exposure times are 1.

When dark frame subtraction is enabled, the camera essentially takes two pictures with the same exposure time - once with the shutter open and then again with the shutter closed. By subtracting the second frame's pixel values from the first frame's, the camera automatically removes most sensor thermal noise from the image.

By always performing a dark-frame subtraction the noise caused by the hot-pixels will be removed from any image. There will be an increase in processing time equal to twice the shutter open time.

Allows you to override the JPG quality setting selected in the Canon menus. Some cameras do not allow a "Superfine" setting in the Canon menus so this menu item allows you to select "Superfine".

Actual quality changes in Superfine mode are camera dependent. Bracketing features are enabled when the camera drive mode is set to continuous or with custom timer on some models. For newer cameras you can use also the high-speed burst mode. Bracketing is the practice of making several exposures of a scene, with each exposure differing from the next by predetermined steps in exposure or focus settings. Bracketing is used to easily capture a range of exposures so that the best exposure can be selected at a later time.

Bracketing is also used to create a series of exposures which will be combined using methods such as HDR processing. In order for bracketing to work, the camera must be in continuous mode, or the custom timer is set to take more than one shot.
