2 Acknowledgements CHDK has to be one of the most innovative improvements to any camera that has ever come along since the beginning of photography. Started out by some people who only wanted RAW out of their raw- crippled cameras, it has now grown into one of the most adaptable, flexible, and full-featured operating systems of any cameras ever made. We are all extremely grateful for the work that everyone has put into this arena of discovery, implementation, coding, sharing, camera testing,

New features are accessed through CHDK-specific menus, rather than the default camera menus. As CHDK is continually evolving, new features are often added. This means some of the listed features depend on you using a version of CHDK that has those features. Check out the Downloads page for information on fin

Dist Valu” (OSDV), and also to quickly set the focus distance. When updating the “Override Subj. Dist. Valu” with the left/right buttons, the value will be changed by the amount set in the “Value factor.” So “1” changes the OSDV by 1mm, “10” changes by 10mm, and so forth. In this way the OSDV can be updated faster than trying to change the overr

11 Bracketing in continuous mode < Extra Photo Operations < Main Menu 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. The bracketing fea
