We are going to convert the selected area i.e. everything except dress to black and white. To do it, I am going to use Gradient Map. Go to Image>Adjustments>Gradient Map.
Your image might be converted to some weird color like mine.
This is because our foreground color and background color are not black and white. To fix it, click on the gradient in Gradient Map panel.
Now choose Black to White Gradient. Press OK.
And your work should be done now.
I hope that you like this tutorial.
