Rule of odds
The rule of odds applies to repetition and rhythm in a frame. We seem to like repetition and rhythm in a frame, just like we do when it is about music.
The rule, which is more a guideline or a rule of thumb, simply says that you should try to have an odd number of objects repeating, rather than an even one. Simple, right? So simple that you can question if the rule works at all! I’ll let you be the judge of that, but it is always good to be more aware of the composition of what you put in your frame, and the rule of odds is just one more to build into you set of tools and skills you use as a photographer.
Take a look at the pillars in the image below. There are 5 of them, not a coincidence at all. Some say that our eyes like to rest on the middle one, as this gives balance to both sides.
Some say that we have a tendency to group objects that are close to each other into one, to give us a better overview and simplify things. Therefore simple counting of objects may not always be the way forward. Take a look at the image below. Here the worn down wood pillars could be counted as 8 pieces, but you will have a tendency to group the 2 pillars to the right as one, and the 3 pillars in the middle as one as well, giving a total of 5 “pillars” rather than 8 as you would get counting them individually.
Another example below with the same point, that the 5 thinner stems to the left of the middle visually count as one. Notice also how the lack of rhythm in the spacing of the stems makes this a rather messy image to look at, even though the subject as such is simple.
Finally we notice what is closer to us more than what is in the distance, so in the final example below, you probably notice the 3 parasols in the foreground sooner than the 8 ones in the background, although the reflections in the pool itself is worth an extra look.
