Photos are most often captured in the proverbial blink of an eye. But slowing down the shutter-speed can yield some amazing photos that can't be seen with the naked eye. Slow shutter speeds and long exposures mean capturing a longer amount of 'time', as well as light. This could give you smooth, rippleless water, or light trails down a highway, or epic night and astro shots where there would technically be very little light "in real life". Slow shutter-speeds can ALSO convey a sense of speed with motion blur. There are loads of techniques and skills that you can use in conjunction with a slow shutter speed. Light painting, abstract shots, and panning, to name a few. For most shots with a slow shutter speed, you'll want to keep the camera steady on a tripod or fixed surface, but you can get some tremendous shots with ICM (Intentional Camera Movement) - there is a difference between out of focus and intentional blur, though so look to get some creative angles and movement to add nuance to your image. Don't forget to look up as well - capturing the movement of clouds is also a good use of slow shutter speeds - just remember to ensure you don't lose detail in the exposure (or use an ND-filter).
