Flash exposure compensation in Non-TTL Auto Flash ˙ mode In this mode, if you don't set the same aperture on the lens as that set on the SB-28, you cannot obtain the correct exposure. Therefore, to make exposure compensation, vary the aperture set on the camera while retaining the aperture set on the SB-28. • Read the flash shooting distance range as shown on the SB-28 without changing the aperture set on the SB-28. Flash exposure compensation in Manual Flash ƒ mode In this mode, you can obtain the correct exposure by balancing three factors: flash output level, flash-to-subject distance, and aperture. You can calculate a correct aperture and flash shooting distance range by using the guide number equations on page 56. -First set the exposure indicated by the camera, then (1) use a different aperture on the camera than that on the SB-28, or (2) select an output setting ranging from full output (1/1) to one sixty-fourth (1/64). For example, the subject will be overexposed if you use a larger (smaller f-number) aperture on the camera than that set on the SB-28 or choose a higher flash output level setting, and underexposed if you do the opposite. • Although the indicator bar ¡ on the SB-28's LCD panel changes as you change the flash output level, go ahead and shoot anyway. 75
