Focus Merge

The excellent Focus Merge command lets you combine a set of focusstacked flower photos into one image with front-to-back sharpness. Go to File> New > Focus Merge, then add your set of photos and click Merge. Once done, you’ll see the Sources Panel appear. This lets you manually correct any blurry areas if parts of the merge have been unsuccessful. Toggle on the eye icon, then click through your set of photos to see if a sharper area can be found in a different frame. If you find such an area, you can switch to the Clone Tool to clone it in.
