Using The Zoom - Nikon COOLPIX P90 User Manual

Using the Zoom

Rotate the zoom control to activate optical zoom.
Rotate in the direction of g to zoom in on the subject.
Or rotate in the direction of f to have a wider view.
Rotating the zoom control all the way in either
direction will adjust the zoom quickly, while rotating
the control partially will adjust the zoom slowly.
A zoom indicator is displayed at the top of the monitor
when the zoom control is rotated.
Digital Zoom
When the camera is already at the maximum optical zoom magnification, rotating
the zoom control in the g direction will trigger digital zoom. The subject can be
magnified up to 4× of the maximum optical zoom ratio.
Focus will be on the center of the frame and the focus area will not be displayed
when digital zoom is in effect.
Optical zoom (up to 24×).

Digital Zoom and Interpolation
Unlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnify
images, resulting in slight deterioration of picture quality according to the image size (A108) and
digital zoom magnification.
Interpolation is applied at zoom positions beyond V. When zoom is increased beyond the V
position, interpolation is initiated and the zoom indicator turns yellow to indicate that interpolation
is being applied.
The position of V moves to the right as image size decreases, allowing for confirmation of the zoom
positions at which shooting without interpolation is possible at the current image size setting.
• By using Digital zoom (A145) in the setup menu (A135), it is possible to restrict the
magnification of the digital zoom within a range where images may not deteriorate, or to set the
digital zoom so that it will not operate.
