Realistic Eye Painting: A Step-By-Step Guide

Painting realistic eyes is a challenging task, even for the most seasoned artists. However, with the right techniques, anyone can learn to paint eyes that bring their portrait to life. The key to achieving this lies in understanding the structure and shape of the human eye, as well as the materials you're working with. This allows you to accurately capture the intricacies of the eye, such as the interplay of light and shadow, and the vibrant colours within the iris and pupil. By following a step-by-step process, from sketching the basic shapes to adding the final details, you can create a stunning, realistic eye that captures the true essence of your subject.

Understand the structure of the eye

Understanding the structure of the human eye is key to painting realistic eyes. The first step is to draw in the upper portion of the eyeball. Using a brown or dark red coloured pencil, create a downward curved line, leaving 3-4 inches of clearance on both sides. The eyeball is not white but appears grey due to shadows cast by the eyelid, forehead, and eye cavity. Therefore, it is best to paint the eyeball a light grey, with the centre being the lightest and the tops and bottoms in slight shadow.

Next, create the tear duct, which should be rounded and smoothly transition into the bottom and top eyelids. The tear duct looks like a "c" shape coming out on the left portion of the curve. Connect the tear duct to the right portion of the eye line by creating a curved horizontal line. The outer contour of the eye should be sketched using a small, pointed brush. From the tear duct, draw a straight line that is slightly tilted, followed by a soft curved line that connects to the back corner of the eye. The bottom line is softer and will swoop under the eye, connecting to the tear duct and back corner.

The iris is the part of the eye that directs the gaze, and each iris in a pair of eyes has a specific angle. To ensure both eyes are looking in the same direction, measure the angle from the highest point to the lowest point, and ensure these two points are opposite each other. Knowing this angle will help map out the shape and location of the iris. The iris usually has a bright colour and can have tiny, radiating lines. The pupil and iris should be blocked in with a flat, medium-toned colour, and the edges of the iris and the area around the pupil should be darkened. Depending on the lighting, pupils can be big or small, and the whites of the eyes will be tinted depending on the lighting situation.

The eyelids should be shaped according to the iris, which is round. Depending on the expression of the eye, the eyelids may partially cover the iris and pupil, but the shape of the eye remains the same. The crease above the top eyelid should be sketched in, along with the creases under the eyelid.

Sketch the outer contour

To sketch the outer contour of a realistic eye, you must first understand the structure of the human eye and its various shapes and curves. Most eyes generally have an almond shape, but they can vary from person to person, becoming more or less rounded. The iris is the part of the eye that directs the gaze, and each iris in a pair of eyes has a specific angle to it. To ensure your eyes are looking in the same direction, you must measure the angle from the highest point to the lowest point, ensuring these two points are opposite each other. This knowledge will help you map out the shape and location of the iris.

The tear duct is another crucial element in sketching the outer contour of the eye. It should be rounded, and the transition to the top and bottom eyelids should be smooth. To begin drawing the outer contour, start by drawing the upper portion of the eyeball. Leave about 5-6 inches from the top of your canvas, and using a brown or dark red coloured pencil, create a downward curved line. Leave 3-4 inches of clearance on both the right and left sides of the line.

Next, create the tear duct by drawing a ""c" shape on the left portion of the curve. Connect the tear duct to the right portion of the eye line by drawing a curved horizontal line. Now, you will sketch the outer lines of the eye. From the tear duct, draw a straight line that is slightly tilted, followed by a soft curved line that connects to the back corner of the eye. The bottom line is softer and will swoop under the eye, connecting again to the tear duct and the back corner.

Once you have the basic outer contour sketched, you can start adding the finer details. Use a medium-sized brush to block in the darkest areas, such as the pupil, creases, and under the eyelid. Continue this process until you have blocked in the midtones and highlights. You can keep the paint fluid by mixing in a medium like linseed oil or galkyd. Remember, when painting the whites of the eyes, avoid using pure white paint. Instead, tint the whites according to the lighting situation in your reference or model.

Block in the midtones and highlights

To paint a realistic eye, it is important to understand the structure of the eye and the materials you are working with. The first step is to sketch the outer contour of the eye, using a small brush that comes to a point to create a straight line slightly tilted from the tear duct, followed by a soft curved line that connects to the back corner of the eye. The bottom line is softer and will swoop under the eye, connecting to the tear duct and back corner. Next, sketch the iris and the crease above the eyelid. Once you have the basic shape, you can start blocking in the midtones and highlights.

Blocking in the midtones and highlights is a crucial step in creating a realistic eye painting. This process involves building up the layers of colour and value to create depth and dimension in the eye. Using a medium-sized brush, start by blocking in the larger areas with a value between 6-10, which will be the darkest darks, such as the pupil, creases, and under the eyelid. Then, continue adding layers of colour to build up the midtones and highlights. The midtones will be the areas of the eye that are not in direct light or shadow, and the highlights will be the areas where light hits the eye, such as the tear duct and the corners of the eye.

It is important to keep the paint fluid by mixing a medium into it, such as linseed oil or galkyd. This will help you achieve smooth transitions between the midtones and highlights. Take your time with this step, as it is crucial for creating a realistic and dimensional eye. Remember to refer to your reference photo to accurately capture the light and shadow areas of the eye.

When painting the whites of the eye, avoid using pure white paint. Instead, use a tinted colour that matches the lighting situation in your reference photo or live model. The whites of the eyes will always be tinted and never appear as pure white. You can also add hints of yellow and red to the whites of the eyes to capture the reflected light accurately.

Finally, don't forget to add a tiny line of highlight just above the lower lid. This highlight will create a bright spot that catches the light and adds a sparkle to the eye. By carefully observing the intricacies of the eye and following these steps, you will be well on your way to creating a realistic and captivating eye painting.

Paint the iris

Painting realistic eyes can be challenging due to the intricate details in the iris and pupil, such as fractured light and speckles of colour. However, with the right approach and techniques, you can achieve impressive results. Here is a comprehensive guide specifically focused on painting the iris:

Understand the Anatomy of the Eye:

Before you begin painting the iris, it is crucial to understand the anatomy of the eye. The iris is responsible for directing the gaze and has a specific angle in each eye. To ensure your eyes look in the same direction, measure the angle from the highest point to the lowest point, and ensure these two points are opposite each other. This understanding will help you accurately map out the shape and position of the iris.

Choose Your Colours:

The iris can be a visually striking colour, and its appearance can vary depending on the lighting conditions. Choose a bright colour that you desire for the iris. Additionally, mix unbleached titanium white with a small amount of yellow to create the skin colour around the eye.

Block in the Iris Colour:

Using a rinsed, flat wash brush, load it with your chosen iris colour. Then, proceed to block in the iris colour. Remember to keep the shape of the iris round, and adjust the eyelids accordingly. The eyelids should partially cover the iris, but this should not alter the shape of the iris itself.

Darken the Edges:

To create depth and make the iris more realistic, darken the edges of the iris and the area surrounding the pupil. This simple technique will instantly make your painting more lifelike.

Add Highlights and Details:

Observe your reference image closely to identify any highlights and flecks of colour reflected in the iris. Depending on the lighting and surroundings, you may need to add hints of yellow, red, or other colours to capture these details accurately. These additions will enhance the realism of your painting.

Create Radiating Lines:

To capture the intricate details of the iris, mimic the tiny, radiating lines that you can observe around your iris. These lines, along with the highlights and colour flecks, will give your painting a striking, lifelike appearance.

Remember, understanding the structure of the eye and practising your techniques are key to achieving realistic results. With patience and attention to detail, you can master the art of painting captivating eyes.

Add the finishing touches

To add the finishing touches to your realistic eye painting, there are a few important steps to follow. Firstly, ensure you have accurately captured the light by adding highlights and marks to the painting. Observe your reference image closely to identify any flecks of colour reflected in the eyes and add these to your painting. You can use a damp brush to lighten any highlights that are not bright enough.

Next, use a liner brush to paint the eyelashes. Observe how the top eyelashes arc and mimic this movement in your brushstrokes. Start at the edge of the eye and move towards the inside of the eye, adjusting your brushstrokes to reflect the changing length and prominence of the lashes.

If your subject is wearing eyeliner or mascara, be sure to incorporate this into your painting. You can also add a hint of colour to the eyelids if this is reflected in your reference image.

Finally, remember to step back and observe your painting as a whole. Compare it to your reference image and make any final adjustments to ensure the eye is lifelike and captures the true essence of your subject.
