High Speed Video Test, Canon Powershot ELPH 110 HS / IXUS 125, 240 fps
The 110 HS uses an automatic exposure control in high speed video mode. It uses Canon "Evaluative" light metering. It is difficult to know what shutter speed under various lighting conditions will result without testing. The fastest shutter speed listed in the specs is 1/2000 sec but it is not clear what shutter speed is achieved in high speed video mode.
To advance or go back a single frame HOLD SHIFT KEY & USE RIGHT & LEFT ARROW KEYS.
The purpose of this test was to use favorable lighting conditions so that the automatic exposure control might select a fast shutter speed and minimize motion blur for a tennis serve. Observe motion blur. Bright sunlight and the largest lens aperture were used, f#2.7 (widest angle lens setting).
This is a close up showing the motion blur on the racket and ball. Considerable sky is in the field of view for metering. The background for the ball consists of sky and trees 11 AM direct sunlight (see shadows for direction). The motion blur appears to be very small.
The sensor resolution at 240 fps is 320 X 240. The Vimeo compressed video loses a little image quality relative to the original video file.
