Rule of Odds in Photography, and How to Use It on a Galaxy

The rule of odds refers to the compositional technique of arranging an odd number of similar elements (three or five, rather than two or four) in a work of art. A painter’s guideline, this rule is often applied to photographs as well, and refers to the placement of objects (cups on a table, say) or people (in a portrait, for example). The rule of odds tends to lend a naturalistic, informal quality to the final image.

Where the rule of odds comes from

Wikipedia’s composition article doesn’t cite any particular study for the rule of odds. It’s more of a guideline that’s commonly used by painters and photographers and tends to work well, as an even number of subjects creates a symmetry which isn’t always naturalistic in a casual setting. Preview your pictures to check it works.

The rule of space, leaving free space in the direction a subject is moving, is better evidenced, with a 2011 study cited by Wikipedia. The article suggests odd numbers are preferable, and three is the minimum if you’re including more than one subject. Including one person centred between two others is a configuration people find friendlier.

Rule of odds claims, checked

The rule is repeated over and over and over with four different claims attached. Some are true, some less so. Best to look at actual photos.

Odd numbers always look better

It’s not true that odds always win. This really only applies to more casual groupings, and even then it’s because we tend to see things in pairs as a grouping and it looks more deliberately placed. Formal scenes use even numbers on purpose, from the two halves of a symmetrical building to a couple looking at each other. In these photos the pair is what you’re photographing.

Only the number matters

Three objects in photography can still be boring if you’re not careful. Three objects arranged in an even row make just as static an image as two. But those same three objects in a triangle (with sides of different lengths) will lead the viewer’s eye around the image. Likewise objects of different sizes will create a sense of movement (see Wikipedia’s article on composition for more on this).

Similarly, having one of three objects slightly closer to the camera than the other two will make that object dominant, with the other two playing supporting roles. Our focal point guide covers how to make one element win.

It works with any number of things

This trick works best with small numbers of objects (three or five, say). With more than about seven things, it looks more like a pattern or a crowd and less like an easily countable number of objects. Beyond that, grouping gives way to repetition, and the patterns and textures guide becomes the more useful tool.

You can always fix it in the edit

Cropping can lop off an offending item that’s near the edge of an image and Samsung’s Object eraser can take out a smaller item within the frame, but both methods have a price, be it lopping off part of the frame or leaving behind a patch that your phone has to fill in somehow. Counting before you press the shutter is quicker, and the Object Eraser guide shows when the edit is worth trying.

Lenses and settings for odd groups

With a wide angle lens, the subject closest to the camera will appear larger than the others.

Shooting with a telephoto lens from farther away will compress the scene, making subjects in the distance appear closer to one another.

On the Galaxy S25 Ultra the 5x camera’s closest focusing distance is 30cm, and it’s 80cm on the S26 Ultra, according to Samsung’s support page. That’s farther than you might think, and often means the 1x camera is your best bet for photographing small groups of objects on a tabletop.

Phones in Samsung’s more affordable Galaxy A-series, like the Galaxy A57, don’t even have a telephoto camera, and their so-called “zoom” is just the image from the main camera cropped.

How to arrange three subjects

1. 1

   Turn on the grid

   Recent S-series phones have a Composition guide option in Camera settings. On A-series phones, it's just called Grid lines. Composition guide displays grid lines as well as a level to help you keep your shots straight.

2. 2

   Place the lead subject on a third

   Place the item you want people to see first at an intersection on the grid. This is the focal point of the image, and the rule of thirds at work.

3. 3

   Build an uneven triangle

   Position the other two items such that all three together form a triangle whose side lengths are all different from one another (not in a straight line and not evenly spaced).

4. 4

   Change the distances

   Have your subjects at different distances from you (not all the same size in the frame). For example, you could move one of them closer or further away.

5. 5

   Check the edges and count again

   Look for elements (a cup, a partially photographed person, etc.) along the edges of the frame that might make a three into a four. Try moving just one element and reshooting after each picture.

When an even number is the better choice

If the point of the photo is the relationship between two things (a couple, a reflection and its subject, a before-and-after situation), shoot both. You can also use symmetry to advantage, as with four windows in a 2 x 2 grid.

If you see one thing with lots of room around it, shoot just the one thing. Our negative space guide deals with this approach, the opposite of grouping. In our 21 negative space ideas we only deal with one subject at a time.

Common rule of odds mistakes

• Three objects evenly spaced in a line (as contrived as two!)
• Objects the same size (nothing for the eye to latch onto)
• One object partly out of frame (half an object leads the eye out of the image)
• An object lurking in the background (e.g. photographing three bottles on a table when there’s another on the shelf behind, oops, that’s four!)
• Using three when the message is better conveyed with two
