it is always good to bring flash closer to the object which help to freeze the object even wind or hand shake (for more info please google “Inverse-square law for Light”)

quick explanation : (we have some sample from http://www.rodandcone.com/2008/05/flash-durations-for-canon-580ex-ii-and.html)

1/128 power = 1/36313 seconds Flash Duration —- SCALED to REPORTED DATA
1/64 power = 1/25341 seconds
1/32 power = 1/19232 seconds
1/16 power = 1/12914 seconds
1/8 power = 1/9151 seconds
1/4 power = 1/6107 seconds
1/2 power = 1/4019 seconds
Full power = 1/833 seconds

Canon 580 EXii – Distance from Flash to Sensor: 2 feet
1/128 power = 1/52718 seconds Flash Duration —- SCALED to REPORTED DATA
1/64 power = 1/38845 seconds
1/32 power = 1/26887 seconds
1/16 power = 1/18626 seconds
1/8 power = 1/13039 seconds
1/4 power = 1/8447 seconds
1/2 power = 1/5006 seconds
Full power = 1/871 seconds

simple compare, the lower the power mean we have faster virtual shutter speed which help to freeze the moment (due to wind, hand shake and etc) … so if when we do handheld macrophotography, it is always good to make flash closer to the object …

so some of my testing are base using the flash bracket (which bring the light source closer to the object)
