Record Modes & Menu Options
Program recording mode is an automatic mode but has many menu and function
options available. Shown here with the full info display enabled with live
histogram in the lower right corner. Onscreen icons indicate space for
another 173 still images or 16:58 of video capture. Image size was set at
2304x1728 pixels, *** (Best) quality, Auto white balance, AE metering, and
ISO 100. The battery level is low. The white brackets in the center
denote the auto focus area which is set to Narrow.
When the shutter is half-pressed and the auto focus is locked, the AF brackets
turn green and the selected shutter speed and aperture value
is also displayed.
The Tv (Shutter-speed priority) mode allows you to set a desired shutter speed and the
camera will select the appropriate aperture value. If the shutter speed is too low or
high then the aperture value is displayed in red which indicates that you need to
select a different shutter speed. Shutter speed range is from 1/2,000 to 4 seconds.
The Av (Aperture priority) mode is like the Tv mode, here you select the
desired aperture value and the camera selects the appropriate shutter
speed. In wide-angle the available settings range from F2.9 - F8.0 and F3.5
- F8.0 in telephoto.
The Manual exposure mode gives you complete control over both the shutter
speed and the aperture value. Adjust one or the other until the +/-
indicator disappears when exposure is correct.
