Sim­u­late the ef­fect of a tri­pod and ND fil­ter when you cre­ate a long-ex­po­sure sky to in­ject ex­tra at­mos­phere into your build­ing pic­tures.

CAP­TURE the move­ment of the clouds streak­ing across the sky, and you’ll im­me­di­ately have an in­trigu­ing shot that com­presses time. Place an at­mo­spheric build­ing in the fore­ground and you’ll have some­thing even more re­ward­ing; but get­ting the right ex­po­sure bal­ance in-cam­era is a chal­lenge that will in­volve a tri­pod, high-den­sity fil­ters, and a good de­gree of trial and er­ror.

With long ex­po­sure times typ­i­cally mea­sured in min­utes rather than sec­onds, it’s a great project to as­pire to. But if you al­ready have some suit­able build­ing shots on your hard drive and want to em­u­late the look of streak­ing clouds with­out in­vest­ing in spe­cial fil­ters, the ef­fect is sim­ple once you know how it’s done.

The key to suc­cess lies in sep­a­rat­ing the sub­ject from the sky in a highly ac­cu­rate way, then us­ing a new sky with a spe­cial fil­ter ef­fect to cre­ate the scud­ding clouds. To make the jour­ney as com­plete as pos­si­ble, we’re go­ing to start from the top with an orig­i­nal raw file, and run through the en­tire process. This will give you the chance to fol­low it through with your own pic­tures, and pro­duce some be­spoke im­ages with a long-ex­po­sure feel.

Although the streak­ing clouds are the el­e­ments that catch the eye in th­ese kinds of pic­tures, the true fo­cal point is still the sub­ject in the fore­ground, so tak­ing the time to get the right lev­els of con­trast and de­tail in this area is worth­while. This is al­ways eas­ier to achieve when you have the ex­tra im­age data that re­sides in a raw file, so we’ll start off ad­just­ing that be­fore mov­ing on to the Pho­to­shop an­tics.
