Triage for crit­i­cal sit­u­a­tions

Try to de­velop the abil­ity to choose a set­ting to change in a split sec­ond – you’ll need it

This med­i­cal term, familiar to hos­pi­tal drama ad­dicts, means mak­ing a quick judg­ment on a three-way pri­or­ity, and it may not be too fan­ci­ful to ap­ply the term ‘triage’ to ex­po­sure, be­cause ev­ery shoot­ing sit­u­a­tion de­mands that you pri­ori­tise one of the three ex­po­sure set­tings. Also, when it’s a fast­mov­ing sit­u­a­tion and you’re not in con­trol, which is surely the case with most in­ter­est­ing photography, you need to do this quickly.

If there’s plenty of light, and you have a large-scale sub­ject where noth­ing much is mov­ing, such as a sun­lit land­scape, then you have more op­tions – an f/stop here or there, or a faster or slower shut­ter speed, isn’t go­ing to make much dif­fer­ence. How­ever, when things get crit­i­cal, then one or two set­tings have to give way, and that’s when you need sound judg­ment.
