Thanks to Sam from http://wvs.topleftpixel.com/ for inspiring me through his photography and teaching me that you can take photos at a slower shutter speed that 1/30. One technique that helps with this problem is to use continuous shooting, wherein you take a few consecutive photos, and the motion of pressing the shutter button is prevented on the second and subsequent shots. Another is to use a self-timer (my A610 allows me to set it at 1 second) for the same purpose, and even then you can set it to take up to 10 consecutive shots on its own.
