Back to Removing the Background

Photoshop offers a wide variety of tools for removing backgrounds. I'll walk you through a few of my favorite methods for pulling objects out of their backgrounds with Photoshop. Click on a thumbnail below for step-by-step instructions on removing the background with Photoshop 5.5.

Editor’s Note:

Though this piece uses Photoshop 5.5, many of the tools and techniques presented are still in the realm of “Best Practice”. The current version of Photoshop CC 2015 has an expanded range of tools that present you with the opportunity to remove backgrounds in a variety of doifferent ways. This is especially true of the Healing Tools which include:

  • Spot Healing Brush
  • Healing Brush Tool

Though there are innumerable methods of replacing backgrounds, you also might want to check out how to replace a bad sky using Photoshop CC 2015.

Technique is everything and the absolute key to knocking out and replacing a background is the use a variety of techniques.The choice of tool and technique is more driven by geometry and colour. Here are some tips around replacing a background:

  • Always convert the image to a Smart Object. What you are doing is called destructive editing. Once you remove something, you are essentially stuck with it. Converting the image to a Smart Object preserves the original image which means, if you aren't satisfied with the final result you can always return to the original image.
  • Look for sharp colour changes between the area to be replaced and the are that remains.If there is is a strong change, you can use either the Magic Wand or Quick Selection tool. Both make selections based on color.
  • If the foreground is geometric- think buildings - the Magnetic Lasso tool will be a god send.
  • Pay attention to edges. The "feathering"and blending tools and features will smooth the transition between the two images.
  • Use Layers. By placing he foreground and background on separate Layers, you can control the transition between the two layers and make edits without worrying about affecting the content.
  • Does the background even need to be replaced. There are a host of Blend Modes and Imaging tools in Photoshop that may do the job instead of a wholesale replacement.
  • Learn to use the Modifier keys for selections - Shift and Option/Alt - to refine the edges of the selection.

Still, you can't beat the Best Practices when it comes to imaging in Photoshop. What follows is a collection of tools and techniques that will get you started:
