1. How to Make a Grid Digitally

Step 1

To begin with, make sure you have a reasonable quality digital photograph, as it will be very important for working with later on in this tutorial. I used this image from PhotoDune.

Using Adobe Photoshop, open the photograph at a reasonable size. I prefer to work with A4 size paper (11¾ x 8¼ inches). To begin with it might be best to use a black and white photo so that it is easier to pick out tones and to see the edges.

How your photo should be setup in Photoshop remember a black and white photo might be best to use

In the View button on the top bar, look for the Show option within this and click Grid to show a default grid on your image.

This shows how to bring up your grid in photoshop

Step 2

This may need adjustment in order to make it easier to draw the image, so look for the Preferences option within the Edit button and adjust the grid lines to the size you require. For this tutorial we are going on a gridline division of 8 cm by a subdivision of 2 cm.

This is where to find your preferences for adjusting your grid slices

Step 3

Once your grid is set up correctly, press Shift-Command-4 to take a screen shot from the computer, and then paste the screen shot on top of your original photo layer. Using the resize command Command-T, adjust your image so it matches the canvas size. Then crop the edges with the Crop Tool, found to the left of the screen.

Carefully resize your screenshot to match your canvas

Step 4

You may want to label your grid axes both across the top and down the side as shown below. I prefer to label mine 1, 2, 3 across the top and A, B, C down the sides. Doing this can help you keep track of your grid and ensure you do not get lost in the reference.

At this point you can choose to print off your image to use as a reference or, as I prefer to do, you can transfer the image to a tablet device and use that as your reference source. I find the advantage with this is you do not lose image quality, which you might run the risk of doing if you decide to print the image, and also you can use the tablet device to zoom in on specific areas.

2. Prepare Your Paper

For this particular tutorial we will be working on A4 size paper (11¾ x 8¼ inches). If you have a drawing board to hand, secure your paper onto it with tape so that is does not slide around as you are drawing.

You can choose a large or small drawing board if you wish to do so

3. Drawing Your Grid

Step 1

Start by measuring out how big you want this drawing to be. You can either work to the exact size of the paper or, as I will be doing for this tutorial, you can work slightly smaller. With your steel ruler, measure out a box whose width is half a centimetre smaller than the size of the paper.

Step 2

Use your ruler to measure out the size of your grid. At this point it is best to avoid drawing too small a box, as this can complicate the construction of the image. My best advice would be to use a box that is either 1x1 inches or larger. For this tutorial I have decided to use a box measuring 1½ x 1½ inches exactly.

The size of the boxes for our grid shall be the box on the right 15 inches

Step 3

Draw out your grid on the paper using a sharp 2B pencil with a moderate touch, as you may need to erase these lines in the process. Pressing too hard on the paper or using too hard a lead can leave unwanted indentations on the paper.

Step 4

Label your grid axis 1, 2, 3 across the top and A, B, C down the sides as explained earlier. Make sure the labelling is identical to the one on the photograph. (For the purpose of explaining this tutorial I will be not doing this.)

As with your reference you can label your drawing

4. Constructing Your Image

Step 1

For drawing it is best to continue using the 2B pencil. Before starting to draw, be sure to sharpen your pencil, as one of the most common mistakes I see with this type of work is artists using a blunt pencil to draw. Using the reference, choose a focus point to begin your drawing. Personally, I would choose to start with the headlight as it is a main point of the image. Use a moderate to light touch with your pencil when drawing, as you may need to erase some lines later on.

Begin with a focal point for your drawing In this case the headlamp

Step 2

Continue drawing out basic shapes to define areas of the image. If you have labelled your grid as explained earlier, it should be easy for you to draw these points on the image.

At this early stage it is best to draw out basic shapes and dont focus on details just yet

Step 3

Once you have all the basic shapes in place, we now have to fill in the details. At this point, take care when drawing and be sure to go back to your reference regularly, as a poor drawing at this stage will cause problems when we come to rendering. 

Clean up any loose lines with your putty eraser and make sure you have a clean image to work with for the next stage. I find it best to lightly draw in where your reflections will go, because it can be a very useful guide. Lastly, you may want to leave your grid lines on your page to keep track of where you are on both paper and reference. However, for the purposes of the tutorial I will be removing these.

5. Rendering Your Image

Step 1

Now that we have the outline of the image, we can begin to fill in the details and create our effects.

Our clean line art ready for rendering

We will be using two main methods of applying graphite to the paper with pencils and graphite powder:

  • Cross hatching
  • Circulism
The methods of rendering we shall be using

Cross hatching is applied by a series of strokes in a diagonal direction going one way, then repeating the motion in the opposite direction. Levels of tone can be built up in this method by bringing hatchings closer together or repeating the motions time and again. Circulism involves rotating your pencil with moderate pressure in a circular motion whilst moving the pencil across the page. Like hatching, this can be used to build up tone depending on pressure applied to the paper and how many times you repeat the motions.

Cross hatching can be used for light tones and is very easy to blend with either your tissue paper or blending nub. I use circulism more for darker tones, and it is especially useful for black areas as it gives good coverage on the paper.

Step 2

Start by using a small amount of graphite powder on your soft paint brush to lay down a light base tone on the paper. Apply it using the circulism method described earlier. Continue reloading your brush with powder and working into the paper. Remember only to cover a limited area of the body at this stage.

Begin by laying down basic tones with graphite powder a section at a time

Step 3

Once the first layer is put down on the paper, take a cotton bud and work over the top of this layer using the circulism method, again with graphite powder picking out darker tones. Be sure to follow your reference at this stage to check where these are. Continue applying more graphite powder as and where needed to build up tone, but avoid drawing in heavy black tones at this point as a mistake is very hard to correct.

Remember to build your tones gradually at this early stage

Step 4

After building up the layers with the cotton bud, I would then use a piece of tissue paper to further blend the layers together and help create the seamless gradients we are trying to achieve. For smaller areas such as around the lights and in tight corners around the grille, a small blending nub or another clean cotton bud might be needed for additional blending. 

At this point, check your reference, and if your image is not quite matching the reference, additional tone may need to be added. For this I would use a soft lead (either a 5B or a 6B) and use a tight cross hatching technique. Additional blending with your tissue paper will be needed here.

Gradually work in darker tones with a soft leaded pencil if you need to do so

Step 5

Now you should have your base tones laid down on the paper and we can begin to draw out highlights. We start by using the putty eraser, as it is not as harsh as the gum eraser. On an image like this I find the putty eraser is ideal at creating dull reflections. 

After this you can use the small Tombow erasers for more detailed work, such as creating specular highlights and sharpening up reflections. If you need to create any big white areas, such as in the top left of this image, the gum eraser can be used to achieve these. Apart from cleaning up the edges at the end of this tutorial, this is probably the only time we will be using the gum eraser.

Notice how we are slowly starting to create a reflective surface if we work carefully

Step 6

By now, you will hopefully have a piece of the image which is starting to look more like the reference you are working from. To tighten this area down such as around the headlights, take a mechanical pencil (preferably a 4B). Using a hard touch, work around the edge of the headlight to give the effect of a rubber surround, but again around the highlight areas adjust your pressure on the paper, as you may need to erase this line to give the effect of glare from the sun.

Pay attention to your highlights and know where your main light source is coming from in this case the top-left

6. Rendering Chrome

Step 1

Now that we have an area of the bodywork rendered, let’s go into the super-shiny parts of a car, the chrome parts! In my opinion, this is what makes a car pretty and gives it a real sparkle. 

Begin by applying a small amount of graphite powder onto a cotton bud rather than a paint brush, and work it into the paper. As with the body work, pay attention to your reference and apply tone accordingly. 

As chrome is a very reflective material, it is possible that just a single layer of graphite may need to be applied. From here we will be using a 3B or a 5B pencil to begin filling in darker areas of the headlamp surround. Using a light touch with the cross hatching method is the best way of working here.

As before work a section at a time and build up tones gradually and carefully

Step 2

For light tones near the specular highlights, a standard HB pencil or a mechanical 2H pencil will be required. Using tight cross hatching, layer in a base tone with the 2H mechanical pencil and then go over this using the same method with the HB pencil. 

To finish off, use a small blending nub to blend the two layers together, thus creating a seamless effect. For highlighted areas, use the small Tombow eraser to sculpt these out, taking care as you go. If you have built up the layers using the right touch, this step should be achieved easily.

Erasing becomes more like sculpture as you carve out white areas

Step 3

Now that we have filled in most other tones, we can move on to the really dark tones and blacks to really bring the area together. Using either a mechanical 4B or 6B pencil, begin filling these areas with tight lines and circulism. At this point, pay close attention to the details—in our reference image, for example, you might notice there are trees reflected in this image, so it is worthwhile to include them. It can be time-consuming, but it matters at the end.

Carefully make your marks when rendering small areas like this headlamp

Step 4

For true black tones it is now time to use your black coloured pencil and fill in the black areas around the headlight using tight circulism.

Be careful when applying black tones as mistakes with medium are difficult to fix

7. Working Inside the Headlight and Rendering Glass

Working on the inside of the headlamp involves the same process as rendering chrome on the outside. Be sure to remember to work from light tones building up to darker ones. For rendering glass effects, it is best to use your Tombow erasers and carve out areas of light within the headlamp. 

Once you have done this, go back with your mechanical pencils, preferably a HB and a 2B, and begin filling in the small details that are cut into the glass for projecting different beams of light. Remember to use a light touch at this point, as it is easy to make a mistake with fine details such as these, and repeated use of the erasers may be required.

Now we have worked on the inner-headlight we are really starting to build a proper rendered image

8. Working on the Bonnet and Grille

Step 1

If at any point you find yourself becoming tired, I must emphasise that it is important to take a break from your drawing for ten minutes or so to refresh your eyes and yourself. One of the worst things an artist can do is to carry on working when they become too tired. That is when mistakes happen, which you often don't notice until it is too late.

By now you should have a basic idea of how to go about applying tones showing both metal and chrome surfaces. We shall now continue from left to right of the car, or vice versa for anyone who is left-handed.

Continue applying base tones with graphite powder and brush across the bonnet surface. As this is a wide area, you can break this section up into halves if that makes it easier and more comfortable. Apply additional graphite with cotton buds, and use tissue paper to continue blending these two together. As earlier, use your putty eraser to draw out tone where needed.

Continue rendering the bonnet of the car as before do things a section at a time

Step 2

Work in shadows with a 3B or a 5B pencil using circulism. Blending can be done using a cotton bud or a broad blending nub. At this point you might notice I am leaving gaps in the image around the edge of the bonnet and grille. These are for our black areas, and again it is best to leave this until right at the end, once you are happy with the light and mid tones.

Notice the gap between the bonnet and the wing this will be for our black areas

Step 3

We now move on to the grille. For this part of the image you may notice a human figure reflected in the top left of the grille in your reference image. It would serve you well to include this figure in the drawing. Picking out small details like this will really impress viewers of your work.

Working on small details such as the figure in the grille can be tedious but it IS worth the effort

Step 4

Continue moving across and down, working your way to the bumper at the bottom right of the page.

Continue laying down base tones with graphite as you work across and then work in the details with your mechanical pencils

9. Applying Black Areas

Step 1

Once you have finished rendering all of your mid tones, you can now move on to your blacks. As mentioned earlier, it is best to apply these with a hard touch using the circulism method. You may also find it beneficial to use two black pencils for this stage, as using hard pressure on the paper does blunt your pencil very quickly. It can be very helpful for tight areas to have another sharp black pencil in reserve.

Remember it is best to work in the direction of what ever hand you writedraw with

Step 2

Underneath the grille the blacks do extend out a way, and the best way to blend this together is to take a sharp 7B pencil and, using tight cross hatching, extend the black areas towards the bumper at the bottom right of the image. Further dark tones can be applied using a 6B pencil if you choose to do so.

Hopefully you will now notice having applied our black tones this really brings the image together The end is in sight

10. Finishing Touches

You should now have an image that is virtually complete! It is at this point I would recommend you go over your work and check it carefully against your reference to make sure you have not missed any details. If you have been careful and have taken your time with this image, hopefully you will find that this is not the case.

The final outcome With practice you too can achieve this

To seal your work, you should now spray your drawing with artist’s fixative. This substance prevents any accidental smudging of your drawing when it is in storage or on display.

And Finally You Have a Masterpiece!

Pencil drawing and rendering can be a time-consuming process in today’s digital age but, as you can hopefully see from your completed image, with some of the simplest of tools you can create an image of great beauty!
