2025 Winter Acrylic Painting Challenge,Bonus Video: Increasing Contrast

Master the art of increasing contrast in your acrylic portraits with simple glazing techniques

In this bonus session of the 2025 Winter Acrylic Painting Challenge, we focus on an essential stepincreasing contrast to create more depth and realism. By building up layers and refining shadows, we can bring out key elements in the portrait before moving into the next lesson.

Why Contrast Matters in Acrylic Painting

Contrast is one of the fundamental principles that makes a painting stand out. It helps define the subject, create a sense of depth, and guide the viewer’s eye. Without proper contrast, an image may appear flat or lifeless.

In this lesson, the focus is on:

Strengthening shadows and highlights
Refining shapes with precise brushwork
Using glazing techniques for smooth transitions

Materials Used

Raw Umber Dark
Ultramarine Blue
Alizarine Crimson
Titanium White
Raw Sienna
Matte Medium
Round Detail Brush (Size 2)
Flat Brush (1/4 inch)

Step-by-Step Process for Increasing Contrast

1. Adding Definition to Clothing and Accessories

The first area of focus is the clothing, particularly the buttons and fabric folds. To prevent losing the details, a light mixture of titanium white and raw sienna is applied to the buttons. This ensures they remain visible even after additional layers of paint are added.

Mix titanium white with raw sienna for an opaque highlight.
Apply it in thin, controlled strokes to emphasize the button edges.
Allow the layer to dry before applying additional glazes.

2. Applying a Glaze for Deeper Shadows

To create a darker value for the clothing shadows, a glaze is prepared using raw umber dark, ultramarine blue, and a touch of alizarine crimson mixed with matte medium.

This mixture is semi-translucent, allowing previous layers to remain visible.
It is applied to the edges of the clothing and negative spaces between elements.
A smooth gradient is achieved by feathering out the edges with a dry brush.

3. Refining Shadows in Facial Features

To make the face more three-dimensional, subtle shadows are introduced under the hat brim, around the eyes, and along the mustache and beard.

A smaller detail brush is used for precision.
A glaze mixture similar to the clothing shadows is applied in thin layers.
The darkest areas are carefully deepened while still allowing for soft transitions.

4. Enhancing the Background and Rope Details

The negative space behind the subject is darkened to make the foreground stand out. Additionally, the ropes and scarf details are defined by using precise brush strokes.

A darker glaze is applied to the background while maintaining soft edges.
The spaces between the ropes are carefully shaded to enhance contrast.
Layering shadows on the scarf creates a sense of texture and folds.

Tips for Mastering Contrast in Acrylic Painting

✔ Use a Limited Palette for Shadows: Mixing complementary colors rather than using straight black results in more natural-looking shadows.

✔ Work from General to Specific: Begin with broad shadow areas before refining small details.

✔ Layer Gradually: Instead of applying dark paint all at once, build it up in thin layers to control the intensity.

✔ Utilize Soft and Hard Edges: Hard edges emphasize details, while soft edges create depth and natural transitions.

✔ Check Your Painting in Black and White: Viewing your work in grayscale helps assess contrast levels effectively.

By following these steps and gradually increasing contrast, your painting will gain a greater sense of realism. Whether you are working on clothing, facial features, or background elements, strategic contrast adjustments can make all the difference.

Frequently Asked Questions: Increasing Contrast in Acrylic Painting

Q: Why does my painting still look flat even after adding shadows?

A: The issue might be the lack of balance between shadows and highlights. Try increasing contrast in both areas by brightening highlights and deepening shadows gradually.
