Fine-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.
