1 COM­POSE YOUR SHOT

At this stage, don’t con­cern your­self with any tech­ni­cal con­sid­er­a­tions; con­cen­trate purely on the aes­thetic and worry about sharp­ness later.

2 CAL­CU­LATE DIS­TANCES

De­cide the near­est part of the scene that needs to be sharp – here, the first groyne post – and cal­cu­late the dis­tance from that to the im­age plane.

3 CHOOSE A FO­CAL POINT

Dou­ble the dis­tance and choose a fo­cal point that is that dis­tance from the cam­era. Here, it’s easy: the sec­ond post along the groyne.

4 FO­CUS PRE­CISELY

Fo­cus on the point. If us­ing AF, make sure the AF point is placed pre­cisely where you want it. Use back-but­ton or man­ual fo­cus to en­sure fo­cus is locked.

5 RE­VIEW THE IM­AGE

Zoom in to 100%, check that the fore­ground is sharp and then check the back­ground. Re-shoot with ad­justed fo­cus if nec­es­sary.

6 FI­NAL IM­AGE

Lin­ear per­spec­tive cre­ates the im­pres­sion of depth and ex­ten­sive depth of field with front-to-back sharp­ness en­hances the ef­fect.

AF­TER DOU­BLE-DIS­TANCE FO­CUS­ING the same post but from the fi­nal im­age, in which dou­ble-dis­tance fo­cus­ing was ap­plied. the post is now clearly within the depth of field and is ab­so­lutely pin-sharp

BE­FORE FO­CUS ON THE BACK­GROUND as this crop of the im­age, show­ing the fore­ground post, clearly demon­strates, fo­cus­ing on the back­ground does not gen­er­ate suf­fi­cient depth of field. it is out­side the zone of sharp­ness and is no­tice­ably soft
