""Light Direction" corrections
This correction does not require you to move about from your camera position.
The corrections range from no increase for front light, to a 1/2 stop increase in exposure for side light, usually 1 to 2 stops increase for back light (1 1/2 stops is a popular choice to correct underexposure in back light) and up to 1 stop increase in revealing light.
All these corrections involves increasing exposure, letting in more light. This is accomplished by a slower shutter speed or by opening a larger aperture (ie a smaller f-number). Please also remember that the f-stop will affect depth-of-field and shutter speed affects motion or movement. Corrections can also be done by using the exposure composition dial.
Side light - Light coming from the side of the subject. You amy want to increase the exposure by +1/2 stops in order to slightly increase the shadow detail
Back light - Light coming from behind the subject. Open up 1 to 2 stops depending on your needs. Compensating 1 1/2 to 2 stops may make the backgound washed out, overly bright. Perhaps 1 stop should do the job...entirely up to you...you may want the overly bright background like an aura coming out from the person...for example.."
please do correct me if i am wrong...
