Still Life: Proportion and Placement

1. Understanding and Measuring Proportions

Proportion is simply the relationship of size between different parts of an object, or between different objects in a scene. Our brains are constantly making these comparisons automatically, but when it comes to drawing, we need a more deliberate method.

The most common method for this is called comparative measurement or sighting. It involves using your pencil (or Apple Pencil) as a ruler to compare sizes and transfer those relationships to your drawing.

The following video provides an excellent, detailed demonstration of this technique. It will be the cornerstone of our process today.

The key takeaway from the video is to find a Basic Unit of Measurement (BUM). This is a clearly defined length on one of your objects (e.g., the width of a mug, the height of a piece of fruit) that you will use as a standard to measure everything else.

2. The "Big to Small" Workflow

A common mistake for beginners is to start drawing one object in great detail, finish it, and then realize it's the wrong size or in the wrong place, leaving no room for the other objects. To avoid this, we will work from big to small.

This means we first establish the overall dimensions of the entire composition before moving to individual objects, and then finally to their details. Think of it as creating the main layout of a web page before styling the individual components.

This approach is often called creating an "envelope" or a "bounding box."

3. Expanding Your Measurement Toolkit

While unit measurement is your primary tool, two other techniques are invaluable for checking your work and ensuring accurate placement.

Plumb Lines (Vertical & Horizontal Alignment)
Imagine a perfectly vertical or horizontal line running through your scene. What parts of your objects does it intersect? This helps you correctly align elements that aren't right next to each other. For example, a vertical line dropped from the left edge of one object might align perfectly with the center of an object below it.

Negative Space
Instead of looking at the objects themselves (the positive shapes), focus on the shapes of the empty spaces between and around them (the negative shapes). Often, a strange-looking gap between two objects in your drawing is the first sign that the proportion or placement of one of them is wrong.

For a good text-based summary of all these techniques that you can refer back to, the article "Lesson 4: How to Draw with Accurate Proportions" from RapidFireArt is a useful resource. Sections 2 and 4 specifically cover Plumb Lines and Negative Space.

4. Your Turn: Create the Line Drawing

Now it's time to apply these principles to your still life. Grab your iPad and open Procreate.

Estimated Time: 25-30 minutes

Objective: To create a light, accurate line drawing of your still life composition.

Follow these steps:

1. Set Up: Sit in front of your still life. You must maintain the same position and point of view throughout the drawing process, as changing your position will change the proportions. Open Procreate and create a new layer for your drawing.
2. Establish the Bounding Box: Use the sighting technique (arm locked, one eye closed) to measure the overall width of your entire scene. This is your first BUM. Now, compare that width to the overall height. Is the scene 1.5 times as wide as it is tall? Is it a perfect square? Lightly sketch a large rectangle on your canvas with this proportion. Everything will happen inside this box.
3. Block in Major Shapes: Within your bounding box, lightly sketch the main objects using the simple 3D forms you practiced in Module 2 (cylinders, spheres, cubes). Don't draw details. Focus only on their size and position relative to one another. Use plumb lines to check their alignment.
4. Refine Proportions with Your BUM: Pick a single, clear measurement from your scene to be your official Basic Unit of Measurement (e.g., the height of the smallest object). Use this BUM to check the proportions of everything else. "The large vase is three units tall. The apple is one unit wide." Adjust your simple forms based on these measurements.
5. Check with Negative Space: Pause and look at the empty shapes between your objects. Do the triangular or trapezoidal gaps in your drawing match what you see in real life? Adjust your lines until they do.
6. Develop the Contours: Once you are confident that the basic sizes and placements are correct, refine your simple forms into the true outlines (contours) of your objects. Convert the cylinder into a mug by adding a handle, or refine the sphere into the specific shape of an apple. Keep all your lines light—we're still in the construction phase. Use your eraser with a low opacity to gently fade incorrect lines rather than scrubbing them out completely.

5. Digital Self-Critique

One of the huge advantages of digital art is the ability to get instant, accurate feedback. Here’s a method to check your work.

1. Take the reference photo you shot in the last lesson.
2. In Procreate, tap the wrench icon > Add > Insert a photo, and select your still life photo. This will place it on a new layer.
3. Drag this photo layer so it is above your drawing layer.
4. Tap the 'N' on the photo layer and reduce the opacity to around 50%.

You can now see your drawing underneath the semi-transparent photo. Are your proportions and placements accurate? This is not for tracing, but for analysis. Note any major discrepancies, then hide the photo layer and make your corrections.

Conclusion

Excellent work today. You have now created the solid foundation for your still life. This process of measuring and building from big to small might feel slow and mechanical at first, but it is the fastest path to accuracy. With practice, these checks will become second nature.

Key Takeaways:

• Always work from big to small, starting with a bounding box for the whole composition.
• Use comparative measurement with a Basic Unit of Measurement (BUM) to keep proportions consistent.
• Check your accuracy using plumb lines for alignment and by observing negative space.
• Keep your construction lines light; you are building a scaffold, not the final wall.
• Leverage digital tools like layer overlays to perform powerful self-critiques.

In our next lesson, we will move on to the first step of rendering: analyzing the scene to identify the light source, cast shadows, and form shadows. You'll begin to map out the value structure on top of the line drawing you created today.
