Canon T 90 - Manual (Page 106)

1. One-point spot metering
Only one point is measured in the viewfinder.
1) Put the main subject in the center of the view­
finder so that the spot metering mark covers
it,
2) Press the spot metering button. As shown in
the photo on the right page, when you want to
take a picture of a backlit glass in front of a
bright window, press the spot metering
button so that it covers the glass. (When the
subject with transmitted light is taken, expo­
sure compensation is necessary.)
• When the spot metering button is pressed,
both the shutter speed and the aperture are
displayed at the bottom of the viewfinder.
The fixed dot {•) will then appear at the posi­
tion of the triangle index on the right of the
viewfinder.
