Using Aperture Priority Mode - A
Thismodeallowsyoutoadjusttheaperturewhilethecameraautomaticallyadjustsshutterspeedto
achieveproperexposure.Usingalargeraperture,likeF1.8,allowsmorelighttoenterthelensand
willproduceanarrowdepth-of-eld,idealforshootingclose-upswithasharpforegroundandout-
of-focusbackground.Asmalleraperture,likeF11,allowslesslighttoenterthelensandproducesa
widedepth-of-eld,idealforproducingsharpforegroundandbackgroundinbrightlightconditions.
AperturePrioritymodemaybeusedforcapturingunderwaterpictures,however,itwillbenecessary
tochangethefollowingsettings:
WhenusingAperturePrioritywithoneortwoexternalashaccessories,orcombinationexternalash
andphoto-videolight,turnashsettingtoForcedON.Youwillneedtosynchronizeyourexternal
ashwiththecamera’sinternalashbecausetheinternalashusesapre-ashwhenring.
WhenusingAperturePrioritywithoutexternallighting,changewhitebalancesettingtoBlueWater
Deep,BlueWaterShalloworGreenwateraccordingtowaterconditionsanddepth.

useUp/Down buttontoselectthedesiredaperture
