GeBng  to  know  you  

¡ How  long  have  you  been  taking  photos?  

¡ What  do  you  like  to  photograph?  

¡ What  equipment  do  you  have?  

¡ What  would  you  like  to  learn  in  this  workshop?

Metering  

¡ What  is  metering?  

¡ Different  metering  modes:  ¡ Matrix  ¡ Centre-­‐weighted  ¡ Spot

Focusing  

¡ Manual  focusing  

¡ Auto  focusing  

¡ Focal  point

Focal  point  and  metering  

¡ The  focal  point  determines/influences  the  meter  reading  

¡ SelecIng  the  area  to  meter  

¡ Locking  exposure  

¡ SelecIng  the  focal  point  

¡ Locking  focus

Exposure:  backlit  subjects  

7  

Page 8: Photography workshop Advanced

Two  ways  to  expose  the  backlit  subject  ¡  Focus  on  subject  

¡  Lock  exposure    

¡  Re-­‐compose  

¡  Take  the  photo  

 

¡  Recommended:  

¡  Use  spot  metering  

¡  Focus  on  subject  

¡  Take  the  photo

Exposure  compensaIon  

¡ The  camera  can  record  a  range  of  tones  between  pure  black  and  pure  white  

¡ The  histogram  shows  the  tones  which  are  in  the  photograph  

9  

Page 10: Photography workshop Advanced

Tones:  black,  grey,  white

Page 11: Photography workshop Advanced

Exposure  compensaIon  

¡ So,  the  camera  can  record  a  range  of  tones  between  pure  black  and  pure  white  

¡ But,  the  camera  assumes  that  the  subject  is  mid-­‐grey  

 

11  

Page 12: Photography workshop Advanced

Exposure  compensaIon  

¡ Accordingly,  snow  will  appear  grey,  not  white    ¡ Over-­‐expose  (  +  compensaIon)  

 

¡ And  coal  will  appear  grey,  not  black  ¡ Under-­‐expose  (-­‐  compensaIon)  

12  

Page 13: Photography workshop Advanced

Exposure  compensaIon  

¡ The  camera  assumes  that  the  subject  is  mid-­‐grey  

¡ Early  evening  sky  a^er  sunset:  deep  blue  

¡ The  camera  will  overexpose  and  ‘wash  out’  colour  ¡  -­‐  exposure  compensaIon  to  deepen  the  sky

ISO  ¡ SensiIvity  of  the  sensor  

¡ 100,  200,  400,  800,  1600  …  12,800  …  

¡ ISO,  aperture  and  shufer  speed  

¡ Shoot  at  the  lowest  ISO  possible  (image  quality)  

¡ Changing  ISO  manually  

¡ Auto  ISO  

14  

Page 15: Photography workshop Advanced

 ISO:  low  light  ¡  Greater  depth  of  field  =  smaller  apertures  (e.g.  f/11,  f/16)  

¡  Smaller  apertures  require  the  shufer  to  be  open  for  longer  

¡  Slower  shufer  speed  increases  the    risk  of  hand  shake  (blurring)  

¡  SoluIon?  

¡  Increase  ISO  

¡  Tip:  use  auto  ISO  and  set  minimum  shufer  speed  

¡  Allows  photographer  to  vary  aperture  (dof)  without  blur  

15  

Page 16: Photography workshop Advanced

 ISO:  low  light  ¡ But!  

¡ Higher  ISO  (e.g.  800,  1600)  =  ‘noise’  

¡ ‘Noise’  is  a  grainy  effect  in  the  image  

¡ Tip:  use  the  lowest  ISO  possible  (e.g.  400  rather  than  800)  

¡ With  higher  ISO:  reduce  noise  in  ediIng  

16  

Page 17: Photography workshop Advanced

 ISO:  low  light  

¡ For  long  exposures  

¡ Use  a  tripod  

¡ Set  ISO  to  lowest  seBng  

¡ Double  check  ISO  is  not  set  to  auto!

Basic  ediIng  

¡ File  type  and  size  

¡ Exposure  

¡ ComposiIon:  cropping  

¡ So^ware  

18  

Page 19: Photography workshop Advanced

Basic  ediIng:  File  type  and  size  

¡  File  type    ¡  JPEG  and  RAW    

¡  Shoot  the  best  quality  and  largest  size  ¡  RAW  ¡  JPEG:  Fine  and  Large  ¡  But  think  about  capacity  

¡  Save  in  JPEG  original  size

Basic  ediIng:  exposure  

¡ Recovering  clipped  areas  

¡ Lightening  shadows  

¡ AdjusIng  brightness  

¡ Increasing  contrast  

¡ But  remember:  don’t  go  too  far!

Basic  ediIng:  composiIon  ¡ Cropping    ¡ If  the  scene  or  portrait  is  perfectly  composed,  no  cropping  necessary  

¡ Fill  the  frame!  ¡ But,  we  do  not  always  have  the  luxury  of  Ime  to  compose,  shoot,  review  and  recompose  

¡ Be  aware:  cropping  throws  away  pixels  and  reduces  prinIng  size
