Don’t get the shakes

NPhoto - - Special Feature -

he shut­ter speed used to take a photo plays a cru­cial role in how sharp it is. At slower speeds there’s a greater risk of cam­era shake, the ef­fects of which range from a soft­en­ing of de­tails to a to­tally blurred mess. Longer lenses are more sus­cep­ti­ble to shake, as their size and weight makes them harder to hold steady, and their ex­treme mag­ni­fi­ca­tion means even small vi­bra­tions can reg­is­ter in the im­age. The rule of thumb for sharp hand­held pho­tos is to make sure the shut­ter speed is no slower than the lens’s fo­cal length (see ta­ble, right), how­ever a Vi­bra­tion Re­duc­tion (VR) lens can help you get sharper re­sults at slower speeds.
