This tutorial will explain the steps needed to turn this boring Prius into an awesome street racer. This tutorial is aimed at intermediate users of Photoshop, those who know most of its basic tools and how to use them. This is Part I of a two-part series.
Final Image Preview
Before we get started, let's take a look at the image we'll be creating. Click the screenshot below to view the full-size image. As always, the full Photoshop file is available via our Psdtuts+ Plus membership. I definitely recommend downloading the sample PSD file. Check it our before you get started.
This is the link to the Prius image we'll be using. Create a new document and load the image. Make a selection around the back wheel. Hit Cmd/Ctrl+J to duplicate the pixels to a new layer. Do the same for the front wheel. Turn off those wheel layers for now.
Select the background layer. Then make a selection of the body of the car that includes everything below the windows. Duplicate those pixels. Then transform the body layer by stretching it downwards. Hold Cmd/Ctrl and drag the corner handles to make the edges of the car line up as close as you can.
Make a guide where you want the ground to be, just below where the body ends. Turn on your wheel layers and bring the Opacity down to about 75%. This is so you can see what is going on behind them as you transform them. Transform the wheels so they are nice and big. The bottoms should sit right where your guide is. Then turn the opacity back up on the wheels.
I know that this looks like a mess now, but if you squint, you can see the basic structure of what our car will look like.
Nest both of the wheel layers in its own group. Put a mask on each of the groups. Then roughly paint out everything, except the wheels, and the wheel wells. For now, don't worry about being too neat. We are still just defining the structure of the car.
Put a mask on the body layer and paint out the handles and anything else that looks like it shouldn't be there. You should now have something like the image below.
The first thing we want to do is draw a path around the boundary of the car. There are some parts around the wheels that you will have to make up". Below is what my path looks like.
Notice from the step above, how my path is always inset into the car by a couple of pixels. This is important! Make sure that you do this. Here is how I handled the wheels and the wheel wells.
Make a new layer group called "car." Put all of your layers into it, including the wheel groups and the background layer. Load the selection of the path you drew, feather it 0.5px, and apply the selection as a mask on the "car" group. Click on the path again in the Paths Palette. Then click on the Add Layer Mask button again to apply it as a vector mask on the "car" group. While holding Shift, click on the vector mask to turn it off.
I connected the path to the car in a vector mask so if I ever need to scale or move the car, the path will scale and move with it. This way, I can always have the path handy. If I ever need it later, it will still fit the selection.
Create a new Solid Color Adjustment Layer and fill it with white. Move that layer below the car group. It will serve as our white background.
Now we need to isolate the basic components of the car. I am going to organize it into wheels, paint, lights, and windows. Let's start with the wheels.
Nest your two wheel groups into a new group called "wheels." Next, draw a path that will represent the edge of the wheel wells. When you are doing this, you don't have to draw a path around anything that you already have. In this case, we have already created a path around the boundaries of the car, so we don't have to do that again. Look at my paths below, for an example.
See how I don't have to make the path along the bottom of the wheels? This is because I already did that before. The "wheels" group is nested inside the "car" group, so the bottom of the wheels are already masked off. After you draw the path for the wheels, load the selection of the path, feather it 0.5px, and apply it as a mask to the "wheels" group. Now apply the path as a vector mask like we did before. Turn off the vector mask by holding Shift and clicking on it.
Let's work on the Lights next. Select the "base" layer and the "body" layer and duplicate them. Merge the 2 duplicates into one layer by hitting Cmd/Ctrl+E while they are selected. Name the duplicate "paint." Draw a marquee around the lights and hit Cmd/Ctrl+J to duplicate the selection into its own layer.
Put that new layer into a new group called "lights." Go back to the "paint" layer, draw a marquee around the windows, and hit Cmd/Ctrl+J. Put that new layer into a new group, and call it "windows."
Now draw paths around the lights, load the selection of the path, feather it 0.5px, and apply it as a mask on the "lights" group. Finally, apply the path as a vector mask on the lights group. Then turn it off.
Do the same for the "windows" group. Below is what my layer palette looks like.
Note that we don't need to make any paths for the "paint" layer because we already did for everything else. The paint falls in the negative space that we created for all the other components.
Now that we have isolated everything, we have freedom to concentrate on one component at a time. Lets clean up the "paint" section. We are going to turn this into a 2-door car, so we need to get rid of some lines and one of the handles.
I prefer to work with a clean slate. While holding Option/Alt, click on the eye icon on the "base" layer. This turns off all layers except the one you clicked on. It's handy if you need to work on a specific layer. Make a marquee around the part of the door that is a clean gradient.
Option/Alt-click on the eye again to turn off isolation on the layer. With the "base" layer selected, hit Cmd/Ctrl+J to duplicate the pixels. Bring the duplicated layer just above the "paint" layer and call it "grad." Transform the "grad" so that it covers the entire paint section. Gaussian Blur the "grad" layer by 15px. How is that for a clean slate?
Now I am going to add a mask to the "grad" layer and make selections with various feathers to mask out the parts where we want it to be see transparent.
Here is what my mask for the "grad" layer ended up looking like.
I left the handles out because I am going to go in and do those later.
Make a marquee that covers the top third of the "paint" section. Feather it by 200px.
Just above the grad layer, make a Curves adjustment layer and drag the highlight handle to the left to lighten the image. Hit OK. With the curves layer selected, hit Option/Alt+Cmd/Ctrl+G to make it a clipping mask on the "grad" layer.
With the "grad" layer selected, make a new blank layer. It automatically becomes a clipping mask because it's in between the other clipping mask and the "grad" layer. Go Edit>Fill and choose 50% gray and hit OK. Go Filter>Noise>Add Noise and use 40 for the amount. Make sure monochromatic is unchecked, and hit OK. Transform the noise layer and scale it to 125%. Set the layer to Overlay and bring the Opacity down to 10%. This makes the "grad" layer blend with the rest of the photo better because the grad layer was too smooth.
If you go back and look at the "base" layer, you will see a highlight just below the windows. Draw a path that contours the highlight. Make a selection of the path, feather it by 1px, and make another Curves adjustment layer just above the "grad" layer. Then lighten it a little.
Click on the vector mask for the "wheels" group. In the Paths Palette, drag the vector mask down to the new path button to make a copy. Select the points that make the back wheel-well. Then scale the back wheel-well up, so that it overlaps the paint.
Do the same for the front part of the path. Load the path's selection and feather it 5px. Make a new Curves adjustment layer above the "grad" layer, including all its clipping mask layers. Name the layer "wheel fenders." Below is what the curve should look like.
Stay Tuned for Part II
Part II of this series will be published this week. We'll pick up at Step 24 in the next installment. We don't recommend sitting on the edge of your seat, as you may fall out of your chair.
