Figure 93 Dark and noisy image
Shaken (= blurred) images
Traditional xenon flash has the advantage of stopping the movement. This is result of extremely short and
intense light pulse, which makes it possible for camera to use very short exposure time. Due to weak output of
the LED flash, the exposure time has to be actually increased from the viewfinder mode in total darkness, instead
of shortening it. This allows the sensor to integrate longer and collect more light but also easily creates blurred
images if care is not taken.
