of the eBook, but pay close attention to spot metering (see
“Spot Meter Point” on page <255>).
Unlike previous Nikon DSLRs, the D300 doesn’t really have a
way to visually estimate the area comprised by the center-
weighted area when you set that method of metering. The
area used for center-weighted metering can be changed using
Custom Setting #B5 (see page <541>), but you’ll have to
guess at how large that area is in the viewfinder.
The image area you see in the full viewfinder is 100% of the
area that is seen by the sensor when shooting normally.
However, it is possible for this to be a few pixels off due to
small discrepancies that come up during the manufacturing
process.
Image Quality
I covered it earlier (in “Image Formats” on page <126>), but
since image quality and size settings are something that you
