tech­nique As­sess­ment

Tracey says… I sug­gested Rachel set Man­ual ex­po­sure mode. With the semi-auto Aper­ture or Shut­ter Pri­or­ity modes, the cam­era will try to set a ‘good’ ex­po­sure, but the com­bi­na­tion of dark venue and rapidly chang­ing stage light­ing will throw the me­ter­ing sys­tem, which re­sults in un­der- or over­ex­posed shots. So it’s best to set a ‘catch-all’ base ex­po­sure in Man­ual mode, then tweak your Raw file in ACR.

ex­po­sure Set­tings

Tracey says… While Rachel was al­ready shoot­ing ‘wide open’ at f/2.8, she wasn’t re­ally sure what match­ing shut­ter speed and ISO set­tings to go with. I sug­gested that she stick to f/2.8, but set shut­ter speed to 1/100 sec, as this would freeze most mo­tion, but al­low a lit­tle move­ment blur for a more dy­namic shot. I nor­mally start off at ISO1600 – as that was the speed rat­ing of the film I used back in the ana­logue days, and then re­duce the ISO – or stop down the aper­ture – if the lights get brighter.

Aut­o­fo­cus And Shut­ter re­lease

Tracey says… Rachel had been us­ing a clus­ter of aut­o­fo­cus points, but I per­suaded her to switch to a sin­gle AF point in­stead, and to move this around with the thumb-stick; as we’re us­ing such a shal­low depth of field, it’s vi­tal that the face is pin-sharp. I also set AF-C mode, so the aut­o­fo­cus tracks the per­former, and Con­tin­u­ous-low re­lease mode, to take a se­quence of shots with­out fill­ing the buf­fer un­nec­es­sar­ily.
