In my last post, I explored negative space, also called white space or the ‘rule of space.’ The response was great, so I thought, why not dive deeper with more posts on composition and how it shapes the way we see?

Our eyes see for us, but our brain can trick us.

I want to dive into a technique I find particularly challenging: a composition rule with the unusual name, the ‘rule of odds.’ Lines and groups guide our eyes, and our minds are wired to find certain patterns more appealing. Essentially, our gaze naturally gravitates toward the center of a group. This works beautifully when there are three elements, but with an even number, our focus often drifts to the negative space in the middle instead.

How odd is odd

Our brains are naturally drawn to odd-numbered groups because they make it easy to identify the center of focus. Three elements is the ideal number, as our eyes immediately know where to settle and the composition feels harmonious. Five elements can work as well, but it requires slightly more effort from our perception. When the number of elements exceeds five, it becomes harder for the eye to determine exactly how many there are, and the arrangement can start to feel cluttered or chaotic.

A simple way to handle this is to break larger groups into smaller clusters of three or five. Each cluster creates its own center of focus, guiding the eye naturally and establishing a visual rhythm within the composition. This technique keeps the image balanced and makes it more engaging and pleasing, allowing the viewer to appreciate the harmony without confusion.

Composing down to the number of three

Simplification works hand in hand with both negative space and the rule of odds. At its core, it is about removing anything that is not essential to the composition, allowing the main subject to stand out and the image to breathe. By paring down the elements in a photograph, we create a sense of balance between the subject and its surroundings, while also encouraging ourselves to rethink the composition and apply the rule of odds more effectively.

In painting, this approach is often easier to implement. You simply choose not to include anything that does not serve the painting. In photography, however, simplification requires more effort. It involves careful consideration of what to include, adjusting perspective, cropping thoughtfully, and sometimes even waiting for the perfect alignment of elements in the scene. The challenge lies in shaping reality, rather than creating it from scratch, but the reward is a clean, balanced, and visually compelling image.

Everything true, yet remember photography is about the moment

Our brains are naturally drawn to odd-numbered groups, but remember this isn’t universally true. While odd numbers like three often feel balanced in Western composition, that’s a cultural and learned aesthetic preference. In some visual traditions, symmetry and even numbers are celebrated and considered harmonious. So framing it as a universal rule might be overstating it.

Three elements is the ideal number, yet don’t make this limit you, its very depending on the context, more elements can still feel balanced if arranged thoughtfully. For example, in landscape photography, clusters of five or seven can work perfectly if the eye has clear lines to follow. Suggesting three is always ideal risks making composition feel formulaic.

Simplification as removing “anything that is not essential”, is for sure a good guideline, but in practice, sometimes “non-essential” elements add context, mood, or tension. In documentary or street photography, including background clutter can actually strengthen a photo by telling a richer story. So simplification isn’t always the best approach.

Breaking larger groups into clusters of three or five, I tend to look at this a practical advice a guideline, but be aware that this isn’t bringing you to a mechanical space. Composition is more about flow and visual tension than just counting elements. A rigid focus on numbers can stifle creativity
