Remove white and black backgrounds in photoshop

Today I have a fairly quick Photoshop tip on how to remove white or black backgrounds from images in Photoshop to create areas of transparency. There are several ways to do this, you could use the magic eraser, or just make a selection of the white or black background and then delete it, but I want to show you how to use a blending slider to do it. As well as the blending modes available in the Layers palette, you can play around with blending sliders in the Layer Style dialog box. Let’s get started.
1. Open an image in Photoshop with a predominantly white or black background.
2. Open the Layer Style dialog box by doing one of the following:
  • Click the little fx button at the bottom of the Layers panel and choose Blending Options.
  • Double-click its layer thumbnail in the Layers panel.
  • Choose Layer > Layer Style > Blending Options.
Note: The Blending sliders won’t work on a locked Background layer; you have to double-click the layer first to make it editable.

At the bottom of the resulting dialog box, you’ll see two pairs of sliders-one set for the This Layer bar and another for the Underlying Layer bar. Each of these sliders lets you make parts of your image transparent based on the brightness value of the pixels. The left slider represents the shadows (blacks) in your image and the right one represents the highlights (whites). If you want to change the background of the currently active layer, then tweak the This Layer slider.
3. If you want to hide a white background, drag the highlight slider (the one on the right) toward the middle until the white part is transparent.
As you drag, you’ll see the white areas of the image disappear and the checkerboard pattern (or underlying layer) will appear. Note that any white area will disappear so you need to be careful how far you drag.
Likewise, if the background of your currently active layer is black and the subject (or object in the foreground) is much brighter, you can hide the black part by dragging the shadow slider (the one on the left) toward the middle until the black part is transparent. Very easy and quick.
