. Always 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 color changes between the area to be replaced and they 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 godsend.

Photoshop Knockout Background Images

Pay attention to edges. The 'feathering' and blending tools and features will smooth the transition between the two images. Use Layers. By placing the 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. Background Eraser Tool: This technique uses the background eraser tool in Photoshop 5.5. Total time to remove the background from this image was under 3 minutes.

Channel Mask: This technique uses channels to create a mask. Total time to remove the background from this image was under 2 minutes. Magnetic Lasso Tool: This technique uses the magnetic lasso tool and quick mask mode in Photoshop 5. Total time to remove the background from this image was about 10 minutes. Pen Tool: This technique uses the pen tool to create a path around the image and converts the path to a selection. Total time to remove the background from this image was about 15 minutes.

Combination of Techniques: This technique uses a combination of techniques to remove the background. Total time for this image was about 20 minutes.

Clear the white background in Photoshop then choose Save for Web and Devices. Then pick the format PNG 24 instead of JPEG and make sure Transparency is checked on. Also check the Interlaced box if you're working with interlaced material. Just one thing when you're clearing white around the edges: depending on how wiggled and smooth the edges are, make sure you remove all anti-alised white or near-white pixels. Use Refine edge in Photoshop to extend the selection with a bit of feather into the logo. The other way might work for you, depending on the colors of your backgrounds and the logo, and unless you don't have whites within the logo to use.

In that case simply just drop the logo image with the white edges included into the project and set the blending mode to either Darken, Multiply, or Linear Burn and the whites will disappear. It will only works with certain combinations of colors but maybe worth the try. Apple Footer. This site contains user submitted content, comments and opinions and is for informational purposes only.
