Shutter Release Cable

I invested in a shutter release cable.  My primary reason for doing this is to be able to take long exposure shots (at night or using an ND filter for example) without introducing motion blur due to my being heavy handed with the shutter release button.

The original parts from Canon are ridiculously expensive.  I opted for an eBay clone part from Hong Kong that also has the ability to introduce a timed shutter release and to take multiple pictures with a programmed interval between each shot.  I bought the Yongnuo TC-80N3a (http://www.hkyongnuo.com/e-detail.php?ID=232).  I bought mine from a Hong Kong based eBay reseller.

In order to completely minimise blurry images from camera shake I will:

• Use a tripod to prevent my shaky hands causing motion blur
• Use mirror lock-up mode to prevent the internal mechanics of the camera introducing vibration which can introduce motion blur
• Use the shutter cable release to prevent my pressing the shutter release on the camera from introducing camera shake and motion blur
