Beat the shakes

Photo Plus - - Backtobasics -

BLURRED shots caused by cam­era-shake are a com­mon prob­lem. To avoid this in hand­held pho­tog­ra­phy, the rule of thumb is that you need a shut­ter speed that’s at least the re­cip­ro­cal of the ef­fec­tive focal length. For ex­am­ple, at a zoom set­ting of 50mm on cam­eras that have an APS-C sen­sor, like the 77D and 800D, the 1.6x crop fac­tor gives an ef­fec­tive focal length of 80mm. You’d there­fore need a shut­ter speed of at least 1/80 sec for con­sis­tently sharp hand­held shots. Lenses with image sta­bi­liz­ers al­low slower shut­ter speeds, but to freeze mov­ing sub­jects, you’ll need faster shut­ter speeds. In dull light­ing, use the Auto ISO fea­ture or man­u­ally se­lect a higher ISO.
