Through relationships. By causing a disparity between the shapes, I've given the viewer a means by which they can compare those shapes. "This one is bigger, that one is lighter." The grey square appears to be moving and receding only when compared to the black square.
The process of comparing these shapes requires that the viewer moves their eyes repeatedly around the canvas, and therein lies the true goal of a great composition: controlling that eye movement. |
This states that if you divide any composition into thirds, vertically and horizontally, then place the key elements of your image either along these lines or at the junctions of them. You'll achieve a more pleasing arrangement. But does it work?
Let's look at Edmund Dulac's painting, The Little Mermaid: The Prince Asked Who She Was (above). Dulac was great at using empty space to his advantage, partly because he tended to abide by the Rule of Thirds. |
These are probably the most important aspect of a composition, because you notice them first. When painting realistically, there's no actual line around a subject.
The illusion of a contour is a result of different values and colours contrasting. But even the impression of a line is strong, and our eyes will go to it and follow its length until it ends, or until it meets another line, which we'll follow again. A great composition makes strong use of this natural attraction to lines. |
By creating strong lines for the eyes to follow, we can decide what path we want people to take and where we want that path to end. In this painting you can see a strong contour that follows along the cape, down the woman's arm, to our subject's face, down her arm, and then back up to the cape.
This creates a circular current that keeps the viewer's eyes flowing around the composition, holding their attention. That current also brings their eyes past every key element of the painting, one at a time. And don't forget, whether you're working for print or for websites, the borders of your composition are an implied line, too. |
As well as using implied lines to draw the eye all around a composition, you can use the same method to make someone look immediately at your chosen focal point.
In fact, you can do it repeatedly, from multiple directions. This is particularly useful when your image is a portrait or a pin-up, and the character's face is the most important element. |
Looking at the French artist Paul Gustave Louis Christophe Doré's engravings, not only has he divided his composition into three obvious layers of depth by using three ranges of value, he also creates an imbalance in the proportions of those values.
For instance, he may use a large amount of grey, and a small amount of white, but rarely equal amounts. This reinforces the importance of imbalance to create tension. By letting the composition be dominated by grey, the small accents of white and black garner more attention, and draw our eye toward the subject. |
Black and white are inherently powerful tones. If you use them sparingly, and right next to each other, you can draw the viewer's attention to a particular spot with ease.
When painting, try reserving the purest whites and blacks for your focal point. For instance, if your main character has very pale skin, try placing something extremely dark on them, such as black hair or black clothes. This is one of the easiest and most successful ways of making your subject pop. In my painting Blood Divided, I did just this to make sure the heroine sat apart from the background. |
Colour is an extremely powerful tool, and can inject a piece of art with mood and light. But it's also a strong compositional tool. Just like implied lines and contrasting values, colour can be used to draw the viewer's eye anywhere we want.
As mentioned before, disparities draw the viewer's eye. So, if there's a colour scheme in place that's predominantly red, any other hue (particularly a complementary green) draws attention to itself. Or you can create a disparity between levels of saturation, such as a mainly grey painting with high saturation in a small area. The greater the disparity, the greater the attention it receives. I often use this method to create the illusion of magic or dramatic lighting. A colour can appear intense simply by making the rest of the composition relatively desaturated, and/or complementary, in comparison. My painting Soulborn is primarily red and purple, yet everything besides the similarly hued 'magic' element has been slightly reduced in saturation. |
