Lens-Artists Challenge #400: Rule of Three
When this post goes live, I’ll be spending time with family and friends in Brazil.
Any comments you make are appreciated, and I’ll respond to them in due time.
Photography has so many rules that anyone trying to learn composition can feel overwhelmed. Others simply trust their intuition. This week, Tina covers a rule that not many people may have heard of: the Rule of Three. It is not the same as the Rule of Thirds, “which divides an image visually into 9 equal segments – using two vertical and two horizontal lines.” In a nutshell, Tina explains “that images with three subjects (or more, but always an odd number) are more appealing and therefore more memorable.” In my preferred genres of landscape and nature photography, meeting that rule is not always possible — but I intuitively keep it in mind whenever I compose. I encourage you to visit Tina’s post for her beautiful examples.
The idea is older than the camera. Renaissance painters arranged figures inside implied triangles. Aristotle noted that lists of three are easier to remember than lists of two or four, and furniture makers know that a three-legged stool will sit flat on any floor while a four-legged one will rock. Photography textbooks picked up the same wisdom: an odd number of subjects, especially three, tends to read as more dynamic than an even one.
Why does our eye prefer odd numbers? Two subjects naturally pair off, and the gaze settles between them. Three refuse to pair — the eye keeps moving from one to the next, tracing an invisible triangle, and the image feels alive a few seconds longer. The Rule of Three answers how many subjects to include; the Rule of Thirds answers where to place them. The two rules can — and often do — live together in the same photograph. One more nuance I find useful in nature, where I rarely get to arrange the actors: when one of the three is dominant and the other two play supporting roles, the composition feels even stronger.
In the first image, three Eastern Brown Pelicans (Pelecanus occidentalis carolinensis) — 39–54 in (100–137 cm) long, with a wingspan of 6–8 ft (1.8–2.5 m) — rest on a wet sand flat at the water’s edge. This is the kind of grouping the rule has in mind: three clearly separate birds, each in its own posture — one with its bill tucked to its breast, one with the bill angled down, the third turned back to preen a wing. Nothing merges, so the eye reads three distinct subjects and travels easily from one to the next. The slight stagger — the right-hand bird set back and a little higher up the beach — keeps the line of three from feeling too rigid.
Compare that with three Great Blue Herons (Ardea herodias) — 36–54 in (91–137 cm) tall, with a wingspan of 66–79 in (167–201 cm) — perched above a coastal shrub. Again three birds, again an odd number, but here the two on the left almost merge into a single silhouette while the third stands apart, facing the other way. The eye sees “a pair plus one” rather than three equals — a reminder that the rule leans as much on separation as on counting. The lone bird still balances the frame: imperfect, perhaps, but not without rhythm.
The three Orange Blister Beetles (Nemognatha piazata), each only ¼–⅝ in (7–15 mm) long, show a cleaner example. They are spaced around the thistle bloom at roughly 12, 4, and 8 o’clock, forming an implicit triangle around the flower’s center, and each beetle faces a different direction. To my eye, this is the image that most clearly answers the challenge.
Finally, the Blue Curls (Phacelia congesta), 1–3 ft (30–90 cm) tall and one of my favorite Texas wildflowers. Three clusters ride a single curling stem, but they are not equals: the middle one is the sharpest and brightest; the other two flank it, slightly softer. That is the “one dominant, two supporting” version of the rule — still three subjects, but with a clear lead.
I am grateful for the beautiful images you share week after week, including those for my Stuck in Place challenge. I thank you for taking the time to join in that challenge. Great images! I hope you will join Tina’s challenge, too. Please don’t forget to use the “lens-artists” hashtag in your posts to help people find your wonderful challenge entries.

Beautiful captures of threes. Enjoy Brazil! 😊
Egidio Leitao
Thanks, Pepper.

Once again, for strange reasons, your posts don’t reflect in my reader. I must unfollow and follow you, I guess.
Egidio Leitao
You still show as a subscriber. I guess WP is acting up. So sorry. As I indicated in my last post (last week), I’m traveling and have not posted anything since last Saturday.

Have a fun time, Egidio. Take care.

Love the thistle one, Egidio. Amazing examples! Well captured.
Egidio Leitao
Thank you for the feedback.
Sofia Alves
I love the beetles, so vibrant and so lucky to have found them in such arrangement. I can see why the Blue Curls are your favourites, Egídio, they are beautiful.
Egidio Leitao
Thanks, Sofia.
Anita
I only discovered this rule with this week’s theme, and your photos show it beautifully Egidio.
Enjoy your time in Brazil.
Egidio Leitao
Thanks, Anita. Like me, you photograph a lot of nature scenes. It’s hard to think of rules when we’re photographing wildlife and wildflowers.
Vicki
Great series for the challenge, Egidio.
Three at the thistle is my favourite.
I don’t think I’ve ever deliberately photographed a ‘three’, but I daresay if I went through my archives there would be some somewhere. And they would have been because I liked the composition, or was photographing one subject and 2 more appeared in the frame.
Egidio Leitao
I guess this rule is one of those some of us may use naturally. When I photograph nature, I never think of rules. Nature is unpredictable. I just try to capture the moment as best as I can. Thanks for the feedback.
Lindy Le Coq
Thank you for the excellent description of these photos and how they fit within the rule of three. I always learn from you, Egídio!
Egidio Leitao
Lindy, I’m happy the post was instructional. Thank you for your kind words.

Beautiful images Egídio and enjoy your time in Brazil! 😊
Egidio Leitao
Thank you, Xenia.
Joanne
Wonderful images, Egidio! My favorite is the three orange beetles.
Egidio Leitao
Thanks, Joanne. Nature helped a lot.
Wandering Dawgs
Egidio, incredible images for the challenge! My favorite is the three beetles on the thistle. I hope you are having a wonderful time in Brazil!
Egidio Leitao
Thanks, Beth. It’s wonderful here.
Toonsarah
Excellent examples of the rule Egidio and your explanations about why the shots work are spot on too! Enjoy your time away – no need to answer this 🙂
Egidio Leitao
Thank you, Sarah.
Rupali
Wonderful examples, Egidio.
Egidio Leitao
Thank you.
Steve Schwartzman
You did well with the three blister beetles on a Texas thistle. With multiple subjects, especially if they’re all moving about in the way that pollen-grabbers do, it’s hard to press the camera’s shutter release at a moment when all the subjects look good. It’s the same with group pictures of people: usually at least one person is blinking or has an unflattering expression.

Well done, Egidio!
margaret21
Excellent!
Egidio Leitao
Thank you.
Anne Sandler
Great response Egidio! And thanks for adding the triangle and dominant subject compositional theories.
Egidio Leitao
You’re welcome, Anne. Thanks for writing.
Terri Webster Schrandt
Stunning examples of threes in nature! Enjoy your family in Brazil!
Egidio Leitao
Thanks for the comment and compliment, Terri.
Tina Schell
Very well done Egidio! Your choices are perfect and your explanations are spot-on. My favorite of course is the thistle. First the colors are glorious and second the 3 creatures are so distinctly placed on the flower, it’s like they were posing for your post! Beautifully said and shown
Egidio Leitao
Many thanks, Tina. The beetles were a great and unexpected moment. As we cannot predict nature, I lucked out how the beetles placed themselves on the thistle.
