Day 5 travel Push up skills

To be ef­fec­tive in the dark you need lose any fear of push­ing up the ISO and take the grain with the gain!

Too many pho­tog­ra­phers have an ir­ra­tional fear of push­ing up ISO. Years ago, chang­ing ISO meant chang­ing your film, but nowa­days you can tweak your Nikon’s all-im­por­tant sen­si­tiv­ity con­trol for ev­ery shot. The fear to­day is of noise – dig­i­tal grain that creeps in grad­u­ally as you turn up the ISO.

How­ever, there are two good rea­sons whey you should learn to love the big-num­ber ISO set­tings. The first is to re­mem­ber the first rule of Boot Camp (see page 32)... Boost­ing the cam­era’s elec­tronic gain is a very sim­ple and ef­fec­tive way of beat­ing un­in­ten­tional blur cre­ated by cam­era shake or sub­ject move­ment. Re­mem­ber, it is al­ways bet­ter to have a grainy shot than a blurry one.

Sec­ond, high ISO set­tings are lib­er­at­ing. They let you take pic­tures in sit­u­a­tions where you sim­ply wouldn’t other­wise get a shot: in places where you just can’t use a tri­pod, or even in places that are so dark you can’t even see what is front of your eyes. ISO fol­lows a scale where each time you dou­ble the num­ber you get a one-stop in­crease in sen­si­tiv­ity. So, go­ing from ISO100 to ISO1600 is a four-stop im­prove­ment, al­low­ing you to in­crease the shut­ter speed from 1/8 sec to 1/125 sec (if the aper­ture and over­all ex­po­sure stay the same).
