Shutter time was set by the camera's built-in autoexposure
Another technically important fact is that all the automatic functions of the camera can be switched off programmatically (like auto-white balance and autoexposure
Similarly, for this time-consuming problem, Ekstrand and Zhang  presented an autoexposure
technique in which the required exposure time can be predicted automatically according to the reflectivity of the measured object surface.
High-resolution CT (HRCT) images were acquired by using a 16-row multislice CT scanner and the following parameters: 120 kVp and autoexposure
control, 140-170 mA, 0.75-mm slice collimation, 12-mm feed/rotation, 0.5-second rotation time, and lung window settings (level = -500/width = 1500 HU).
The spectrometer is lightweight at <2 lb and is easy to operate with the autoexposure
and autoshutter features.
The device also features a much-improved five megapixel camera with autoexposure
Rely on autofocus and autoexposure
modes in foggy conditions.
As with other types of sky photography, your camera's autoexposure
setting probably won't give good results (even if it has a night mode).
The Elura's simple exposure wheel allowed me to show students how to correct for difficult lighting conditions that still fool most autoexposure
Image acquisition is optimized by using a monochrome camera and advanced illumination, autoexposure
, and autofocus techniques.
