How to select a part of your image and make the background black and white whilst the selected by of the image is in color.

Step 1: Open your image into photoshop and unlock the layer.
Step 2: Start selecting the part of the image you want to stay in color with the pen tool. In my example its the main taxi.
Step 3: Once selected right click on the shape you made with the pen tool. Right click on this and press mark selection and feather radius 3 pixels.
Once the selection is made, delete the shape layer. Then click on the main image which should be called layer 0, and press CTRL + C and CTRL + V to copy and paste the selection. YOu should now have the selected part of the image in my example the taxi in a separate layer by itself.
Step 4: Click on the main layer which is called layer 0 and either press CTRL + U or go to image, adjustments, hue and saturation and make the saturation -100.
You should now have the effect.
Step 5: to make the colors look more rich copy the taxi layer so that you have two of them and choose on the newest taxi layer so that the blend mode would be soft light.
