III. CAMERA CONTROLS 11White Balancereview, hold down the Print/Share button and press the Magnify button to magnify theimage. Once magnified, the AF point selector enlarges and the AE lock button reducesthe image. When option 1 is selected but the image has not been magnified, these twobuttons retain their regular functions.C.Fn-02, Long exposure noise reduction, now has 3 options: Off, Auto and On.Please see “Noise Reduction” for a discussion of this feature.Note that, when C.Fn-12-1 (mirror lockup) is set, the camera should not be pointedtoward the sun or any bright light source. Doing so could damage the shutter curtains,causing stray light to enter or damage the imaging sensor.White balance controls are the same as on theEOS 20D. The modes are Auto (AWB, approx. 3000-7000K), six Preset settings (Daylight, approx. 5200K;Shade, approx. 7000K; Cloudy/twilight/sunset, approx.6000K; Tungsten, approx. 3200K; White fluorescent,approx. 4000K; Flash, approx. 6000K), and twomanual modes (Custom: photograph a white subjectserving as the WB standard and use the [Custom WB] menu to specify that image as thestandard; Color Temperature: specify directly from the [Color temp.] menu).WB correction (Blue/amber or Magenta/green, +/- 9 levels, set with the multi-controller)can be applied to any of these settings within a range of 2000 to 10000K. WBbracketing can be enabled for three images at the current color temperature setting,then blue bias and then amber bias or current color temperature setting, then magentabias and then green bias. The range is +/- 3 stops in one-stop increments. Becausethree images are recorded with one press of the shutter button, write times to the CFcard increase proportionally. Also, when WB-BKT is set, the shots remaining willdecrease to about one-third of the normal quantity. With C.Fn-09 [Bracketing sequence/Auto cancel], the bracketing sequence can be changed and the bracketing can becanceled automatically.A5SHIFTAB 3BKTBKT OKSHIFTG2SETABGM
