Case Study 1: Ceiling Fan

This is a classic example!

One fine afternoon, I was lying on my couch and taking pictures of ceiling fan at different shutter speeds. Thought of sharing the results with exif information.

The action is smooth in first image since shutter was open for enough time:
Shutter Speed 1/10s; Aperture f/8.0; ISO 200
Focal Length 55mm; 35mm equivalent 82mm

In second image, the shutter speed is faster and still it has enough light because aperture is wide open (from f8 to f4):
Shutter Speed 1/20s; Aperture f/4.0; ISO 200
Focal Length 55mm; 35mm equivalent 82mm

The last image is dark and the action is almost freezed because shutter was open for less time:
Shutter Speed 1/60s; Aperture f/4.0; ISO 200
Focal Length 55mm; 35mm equivalent 82mm
