Chapter 8 Capturing Images with Advanced Setting Menu82Photographing andPlaying Images(2) Changing the exposure modeThis system provides four exposure modes: the Program AE mode, the Shutter-priority AE mode, the Manual mode, and thefocus-priority mode. You can switch the mode as required.Note: The exposure mode is the Shutter-priority for [DF/FL] (dark field/fluorescent) scene mode, and the Program AE forother scene modes.1 Display the [CAM MENU: CAMERA] long screen.2 Press the [EXP MODE] button.The [EXP MODE] submenu appears.3 Select an exposure mode from the options below.For details of each option, refer to the table below.• [PROG] (default)• [S.AE]• [F.AE]• [MANU]When you select any of the above, the submenu closes andthe icon of the [EXP MODE] button changes accordingly.Exposure mode settingExposure mode optionsOption DescriptionPROGProgram AE. The exposure time and camera gain are automatically set according to the brightness of thesubject.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.AEFocus-priority. Increases the camera gain to keep the exposure time short for an easier focusing operationduring 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, thecamera gain lower, and the noise less compared to the F.AE mode. Captured data is shown as a still image.MANUManual 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 asfluorescence microscopy and observation under a stereoscopic or metallurgical microscope.Automatic change of the exposure modeIn 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].132Select anexposuremode.
