Digital SLR Photography - - Contents -

… And here’s how to edit it. Bring your fo­cus stack to­gether eas­ily and in min­utes in Adobe Pho­to­shop

1 LOAD

FILES INTO STACK Save your fo­cusstacked shots in a folder on your desk­top. Open Pho­to­shop with­out any im­ages and go to File> Scripts> Load Files into Stack. When the win­dow opens choose Use: Folder, and lo­cate the folder with the saved shots. Make sure At­tempt to Au­to­mat­i­cally Align Source Im­ages is checked and press OK.

4 MASK

SHARP­NESS Press D on the key­board to set the de­fault colours of black and white. If white is in the fore­ground press X to switch to black. Press B to se­lect the Brush tool and use the Brush Pre­set picker to set Hard­ness to 50%. Change brush size with the left and right square bracket keys. Now paint over the blurred area to re­veal sharp­ness.

2 CROP

THE IM­AGE The im­age may need to be cropped. Zoom into the im­age by press­ing ctrl and the plus(+) key, and scroll around by hold­ing down the space­bar and left mouse- click­ing. If you need to crop, press C to ac­ti­vate the Crop tool and se­lect Orig­i­nal Ra­tio in the top left tool menu. Left mouseclick, drag the guide and press En­ter.

5 FIX

MASK­ING MIS­TAKES If you ac­ci­dently paint over the wrong part of the im­age and re­veal blur rather than sharp­ness, press X on the key­board to set white as the fore­ground colour. Paint over the of­fend­ing area be­fore switch­ing the fore­ground colour back to black. Change brush size as re­quired us­ing the left and right square bracket keys.

BACK­GROUND

FORE­GROUND

3 CHECK

LAY­ERS With the im­age still zoomed, click on the eye icon to the left of the top layer on the Lay­ers panel. Scroll around to see where sharp­ness starts and ends. If you have three im­ages, leave vis­i­bil­ity of the top layer off so you can do the same again. Turn on vis­i­bil­ity and at­tach a layer mask to the top layer ( and mid­dle layer if you have one).

6 FLAT­TEN

& SAVE Once happy with the blend­ing, it’s time to flat­ten and save the im­age. Click on the menu rep­re­sented by four hor­i­zon­tal lines at the top right of the Lay­ers panel, then se­lect Flat­ten Im­age from the list of op­tions. Press Ctrl+ Shift+ S to bring up the Save As di­a­logue, save as JPEG if you’re done or TIFF if you in­tend to add Ad­just­ment Lay­ers.
