Installing and using CHDKThis is part of the NIR camera wiki.
Follow these steps to prepare an SD memory card for each camera so that temporary firmware is loaded to your cameras after they are turned on. This firmware provides several useful enhancements including the ability to trigger the cameras remotely via the USB port. In this process CHDK (Canon Hack Development Kit) is installed on the camera's SD card. It loads each time the camera is turned on, and does not change the camera permanently. To turn on a camera with CHDK installed on a bootable SD card, hold down the power button until the camera starts. Just pressing the button once starts the camera in Preview mode and prevents switching to record mode (where you can take photos). Choosing an SD card

Installing CHDK using a Mac or Linux (For more current procedures, refer to Dave Mitchell's page)
Some useful CHDK settings to start with (Some of the following no longer applies to recent releases of CHDK)CHDK Main Menu To enter the CHDK main menu on a Canon A495, press the PLAY button on the back of the camera, then press the MENU button. To exit CHDK, press the PLAY button. On some other cameras, the buttons used are different. Enable Remote To allow remote shutter release via the USB port, you must enable remote operation. In the CHDK Main Menu select Miscellaneous Stuff/Remote Parameters/Enable Remote. Synchronous Shutter Release To precisely synchronize the shutter releases of two cameras connected to a timer or switch, you must enable synchronous remote in CHDK. In the CHDK menu, under Miscellaneous Stuff/Remote Parameters, turn on Enable Remote, Enable Synchable Remote, and Enable Synch. With this setting, CHDK uses the first signal from the timer to get ready to take the photo (focus, exposure, any other auto stuff) and then takes the photo on the second signal. So the camera shoots on every other signal, and a timer must be set accordingly. Shutter Priority -- The Canon A495 does not have this option, but CHDK adds it. It allows the camera to set the exposure automatically while keeping the shutter speed high and constant (thus reducing blur). On sunny days, setting the shutter speed at 1/800 second is suggested (the IR camera will require more light and maybe a slower shutter speed, but adjusting ISO or f/stop can keep shutter speed high and help reduce motion blur). To enable shutter priority in the CHDK menu, select Extra Photo Operations/Disable Overides = OFF, then Overide Shutter Speed = 1/800 (or whatever), then Value Factor=1. Generally you should deselect or turn OFF everything else on that menu page. |

In general, manual settings are preferred over automatic settings so each photo has similar qualities and will stitch together well. The exception is exposure, which is a challenge to set correctly before launch, and may need to change during a flight. Manual Focus -- the A495 can be set on "infinity" focus mode. The camera has to be in "Manual" mode for this option to appear (have to confirm this). For most mapping flights, everything will be in focus if the camera is focused on infinity. Some additional information is needed to confirm how this "infinity" mode works. Daylight White Balance -- When the camera is in "Manual" mode, select the sun icon for daylight white balance. Image Stabilization -- The A495 does not have image stabilization. That's okay because it probably does not help on balloon or kite flights. Exposure Compensation -- On sunny days, the view from above is bright, and the automatic exposure system can be fooled. The A495 can compensate for such scenes by reducing the exposure in increments of 1/3 f-stop. Setting the Exposure Compensation to -1/3 or -2/3 can eliminate overexposed highlights. ISO -- On sunny days, ISO 80 (the "slowest" sensitivity to light) should produce the crispest images. On darker days, setting the ISO higher (100-200) will allow faster shutter speeds (less motion blur), but the images will be noisier (grainy). ISO settings higher than 200 are not recommended because the images will be rather noisy, but in dim light this may be the only option. Battery Saving Features -- (must confirm with the A495)

Synchronous Shutter Release To precisely synchronize the shutter releases of two cameras connected to a timer, you must enable synchronous remote in CHDK. In the CHDK menu, under Miscellaneous Stuff/Remote Parameters, turn on Enable Remote, Enable Synchable Remote, and Enable Synch. With this setting, CHDK uses the first signal from the timer to get ready to take the photo (focus, exposure, any other auto stuff) and then takes the photo on the second signal. The timer must be set accordingly. Some options available when CHDK is installedShutter Priority -- The Canon A495 does not have this option, but CHDK adds it. It allows the camera to set the exposure automatically while keeping the shutter speed high (thus reducing blur). On sunny days, setting the shutter speed at 1/800 second is suggested (the IR camera may require more light and a lower shutter speed). To use shutter priority in the CHDK menu, select Extra Photo Operations/Disable Overides = OFF, then Overide Shutter Speed = 1/800 (or whatever), then Value Factor=1. Generally you should deselect or turn OFF everything else on that menu page. Configuration using the camera's normal menu settingsPersonal preferences vary, but these choices have worked well during mapping flights. In general, manual settings are preferred over automatic settings so each photo has similar qualities and will stitch together well. The exception is exposure, which is a challenge to set correctly before launch, and may need to change during a flight. Manual Focus -- the A495 can be set on "infinity" focus mode. The camera has to be in "Manual" mode for this option to appear (have to confirm this). For most mapping flights, everything will be in focus if the camera is focused on infinity. Some additional information is needed to confirm how this "infinity" mode works. Daylight White Balance -- When the camera is in "Manual" mode, select the sun icon for daylight white balance. Image Stabilization -- The A495 does not have image stabilization. That's okay because it probably does not help on balloon or kite flights. Exposure Compensation -- On sunny days, the view from above is bright, and the automatic exposure system can be fooled. The A495 can compensate for such scenes by reducing the exposure in increments of 1/3 f-stop. Setting the Exposure Compensation to -1/3 or -2/3 can eliminate overexposed highlights. Battery Saving Features -- (must confirm with the A495)

Installing and using CHDK
Follow these steps to "reprogram" a pair of SD memory cards so that they load temporary firmware to your cameras when turned on. This firmware provides several useful enhancements including the ability to trigger two cameras simultaneously every 5-10 seconds via the USB port. The "CHDK" or Canon Hack Development Kit must be installed on the camera's SD card. It loads when the camera is turned on, and does not change the camera permanently. Choosing an SD card
