Adobe Photoshop CS6 (MAC) – Background Colour Change

Step 1

Use a photograph of a model on a plain white background, for easy usage. Then copy the layer using CMD + J.


Step 2

Select the new layer and use the Wand Tool (W) to make a selection around the girl. Once done, it should look a little like this.


When done, Inverse (CMD + SHIFT + I) the selection to select the girl rather than the background. Then Cut (CMD + C) the girl in and press the Backspace key in order to leave a hole in the background. The layer with the hole should look like this when we hide the other layer.


Step 3

Now, we’re going to use Gaussian Blur on the layer with the empty space. We select the layer and then go to Filter -> Blur -> Gaussian Blur. In this case, I used a pixel radius of 35. This will soften the edges and make the girl blend in like normal once placed back into the image.


Step 4

Now, we have to put the girl back into the image. We do this by using Paste in Place (CMD + SHIFT + V). If we look at the image without any layers hidden, it should look pretty much the way we started, but with several layers.


Step 5

Now we can start messing with the background colour. Because the girl was photographed against a white background, it’s a bad idea to go for a dark coloured background. Otherwise, the edges will start showing and the image will definitely look Photoshopped.

To change the background colour, we have to add an adjustment layer onto the background layer. To do so, we select the background layer and use the little ‘contrast’ button (Screen shot 2014-03-06 at 11.59.14) at the bottom of the layer screen. We then select Hue/Saturation in order to change the colour. It will now look like this.


As you can see in the layer panel, there is now an adjustment layer above the layer containing the background.

Now, click on ‘Colorize’ in the panel that’s appeared and have a play around with the Hue and Saturation sliders. You can even adjust the brightness if you want. The following is the end result in my case.
