Hold down the MODE button and turn the dial to Av. Aperture should stay the same so that the depth of field does not change in between exposures. Only the shutter speed should change.
Hold down the Image Size Selection button on the front and turn the dial to select JPEG M1 (Medium1). This sets file sizes to about 3 MB and a resolution of around 8.5MP.
Hold down the WB button on the front and set White Balance to AWB (Auto White Balance). Our system automatically corrects white balance so you don't need to do it in the camera.
Hold down the MODE and Metering Mode buttons on top simultaneously and select Continuous Shooting. This way, you'll be able to take all bracketed exposures with a single press of the cable release or shutter button.
Use EOS Viewer Utility software to set Personal Function 8 (Number of shots to be bracketed) to 5 shots. Then hold down the MODE and AF DRIVE buttons simultaneously. Turn the dials so you have 5 exposures at -4, -2, 0, +2 and +4.
