Nikon D300s B5 Center-Weighted Area, B6 Fine Tune Optimal Exposure Gbutton ACustom Settings menu

b5: Center-Weighted Area

Gbutton ➜ ACustom Settings menu

When calculating exposure, center-weighted metering assigns the greatest weight to a circle in the center of the frame. The diameter (φ ) of this circle can be set to 6, 8, 10, or 13 mm or to the average of the entire frame.

Option

Mφ 6 mm L φ 8 mm N φ 10 mm O φ 13 mm P Average

Note that the diameter is fixed at 8 mm when a non-CPU lens is used.

b6: Fine Tune Optimal Exposure Gbutton ➜ ACustom Settings menu

Use this option to fine-tune the exposure value selected by the camera. Exposure can be fine tuned separately for each metering method by from +1 to –1 EV in steps of 1/6 EV.

DFine-Tuning Exposure

Exposure can be fine-tuned separately for each Custom Settings bank and is not affected by two-button resets. Note that as the exposure compensation (E) icon is not displayed, the only way to determine how much exposure has been altered is to view the amount in the fine- tuning menu. Exposure compensation (0 118) is preferred in most situations.
