Taking Photograph With Slow Shutter Speed

Why taking photograph with slow shutter speed? Ok, this what i learnt from the "masters".  We use this for two reasons – first, because it’s quite dark and we need to let more light into the camera. Secondly, because we want to introduce some blur into our photo.  What blurry photos? i thought blur means the photo is tottaly unacceptable..but ya, sometimes we can use blur for a creative effect. 
Slow shutter speeds are easier when the light is low as the shutter can be kept open for a certain longer time to get some effects. A tripod is required or anything that can hold the camera firm as any camera movement whilst the photo is being taken will result in an "unwanted" blurred image.  


Below are an example of how we can use blur to tell a story.  I took this photo in KL LCCT while waiting for boarding my flight back.
