Photoshop: Expand Depth of Field (DOF) with Focus Stacking

Featured Image

We promised and we delivered – here’s our very own Focus Stacking tutorial. To all hardcore photo enthusiasts and pros, this is an article you’ll love.

What is Focus Stacking?

Focus stacking (also known as focal plane merging and z-stacking or focus blending) is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images.

How should I take the photos?

In terms of composition, both the camera and all of your subjects need to remain in the exact same position for all of your images. Take a minimum of two photos with the focus on each one at a slightly different distance. Even if your lens focuses in a way that introduces slight distortion of the out-of-focus areas, Photoshop can align automatically for you, so just concentrate on the photos without worrying about post-processing.

The Automated Method

After transferring all of your images to your computer you need to load all of them into a single Photoshop document. For up to 3 images, opening the first one and then using File > Place for the others is okay. If you have a larger number of photos, however, try File > Scripts > Load Files Into Stack.

A window entitled Load Layers will appear, allowing you to import your images. Press the browse button and navigate to wherever your images are, then select them all and pick Open.

Pro tip: If you put your photos into a separate folder, you can also try Use > Folder.

After selecting the images, you can optionally tick Attempt to Automatically Align Source Images if you think the photos might not be perfectly aligned.

Press OK and watch as Photoshop does the work for you, turning each and very image into a layer.

    Hey, Stefan. That’s terrific! I knew Photoshop would do that I’ve been interested in trying it out, but, well, the truth is I’m too lazy. Thanks for showing me how-to and showing it’s not all that hard.k
