CR-2 PLUS AF Digital Non-Mydriatic Retinal Camera: The CR-2 PLUS AF incorporates Canon EOS technology and provides superb retinal images under just about any condition with integrated AutoExposure, AutoFocus, AutoFundus and AutoCapture.
Shutter time was set by the camera's built-in autoexposure feature.
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 [15] 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.
Unit capabilities include full range UV/VIS/NIR in one scan; very fast scanning, with autoshutter, autoexposure and auto-dark correction; compact design that weighs less than 8 lb (3.6 kg) and has no moving parts; and DARWin SP data acquisition software that produces ASCII-compatible files without post-processing for use with third-party software including SpecMIN, TSG, IOGAS and GRAMS.
The device also features a much-improved five megapixel camera with autoexposure and auto-focus.
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 systems.
Image acquisition is optimized by using a monochrome camera and advanced illumination, autoexposure, and autofocus techniques.
