Exposure mode setting
Exposure mode options
Option Description
PROG
Program AE. The exposure time and camera gain are automatically set according to the brightness of the
subject.
Suitable for bright objects.
S.AE
Shutter-priority. The camera gain is automatically set according to the manual setting of the exposure time.
Suitable when stable responsiveness is wanted for automatic exposure. (e.g., with a stereoscopic microscope)
F.AE
Focus-priority. Increases the camera gain to keep the exposure time short for an easier focusing operation
during capture of a dark object. Bright spots or banding noise may increase with this mode.
Use the [E MODE] function button in combination with this mode to facilitate image capture with less noise.
•
Press the [E MODE] button to change to the Exposure assist mode. Exposure time becomes longer, the
camera gain lower, and the noise less compared to the F.AE mode. Captured data is shown as a still image.
MANU
Manual exposure mode. The user sets both the exposure time and camera gain manually.
Suitable when capture is repeated under a specific exposure setting or for a specific purpose such as
fluorescence microscopy and observation under a stereoscopic or metallurgical microscope.
Automatic change of the exposure mode
In some cases, the exposure mode changes with the following operations:
•
Selection of [SCENE/CSM]:
The mode changes to the one registered as the scene mode/custom setting.
•
Execution of [CLR SET]:
Executing [CLR SET] in the [CAM MENU: NR/SD/SET] screen changes the exposure mode to [PROG].
•
Enabling [F MODE] (focus assist mode):
Setting the [F MODE] (function button) on changes the exposure mode to [MANU].
• Enabling [E MODE] (exposure assist mode):
Setting the [E MODE] (function button) on changes the exposure mode to [MANU].
