In the P (Program) mode, the camera is programed so that the aperture value and shutter speed
are selected automatically according to the subject brightness as shown below. The below
diagram depends on the lens.

Program shift (Ps)
By rotating the main dial or sub dial in the P mode, you can change the combination of aperture
and shutter speed while keeping the optimum exposure.
The program shift setting will not be canceled after
shooting. To cancel program shift setting, rotate the
main dial or sub dial so that the viewfinder indication
Ps changes to P or turn off the power. Program shift
is not available when you are using a flash.
