Aspect ratio, or format, in photography is the proportions of the frame, the relationship between the width and the height of the picture. It depends on the sensor of the camera, but in our digital age, it can be changed in the settings in some types of DSLRs. And it is not without consequences. A picture may be better in a different format and one of the editing techniques is to change the aspect ratio if it’s needed by cropping the picture.

This post will deal with the main formats – there are a lot of others – and with their effects in the storytelling.

Kitten in the GrassHistory : It’s the former traditional TV format and a traditional format in photography.

Effect : Horizontal and vertical lines are balanced, though not equal. The effect is more or less neutral. In the landscape orientation, the horizontal plane is emphasized but the vertical plane keeps a significance too. In the portrait orientation, verticality is emphasized but the subject has enough space on both sides.

Positive points : It is neutral, so it can be used with a lot of varied subject matters.

Negative points : Its neutrality ?

Case study : On the picture above, because of the 4:3 format, we can see that it is not just about a kitten. It is lying in a relaxed way (horizontals), hidden behind some herbs (verticals) and watching what is on the other side. A different format would have focused more on the lying position and the lack of interaction between the vertical and horizontal lines would have told a different story.

Flat MountainsHistory : It’s a former movie format and a traditional format in photography (35mm films).

Effect : It is less neutral than the 4:3 format, with an emphasis on the horizontal plane. Nevertheless, this format is more natural as it is more or less the same as the human field of vision in the sharp zone.

Positive points : It is very widespread nowadays and we have been conditioned to see it as a ‘normal’ format. More specifically it is a good aspect ratio for horizontal subjects, at least for subjects in which verticality is not important. A very good format for landscapes and for whole body pictures in the portrait orientation.

Negative points : Unless particular conditions, it is not suitable for vertical subjects in the landscape orientation, so it is not a good aspect ratio for portraiture. Even in the portrait orientation, shooting portrait with this format is not so good because the person seems to be locked in a very tiny space.

Case study : In the picture above, there is no real vertical lines. It is a pasture mountain and despite the fact that it is a mountain range, the landscape seems to be flat. The mountains seem to be interwoven from this point of view and the 3:2 format is well suited to give this impression. A different format would have broken the effect by adding some vertical significance.

Tight in a bud

Case study 2 : A counter example of what has been said in the negative points. When the story needs a closed space it may be a good format. In this picture, Tight in a Bud, the eyes are shut and the positon of the head and the shoulder suggests some kind of retreating into one’s shell, or a moment before opening up, depending on what the viewer wants to see in it.

Faded Iris 2History : It was a traditional photography format from the 1950s to the 1970s. This format has regained popularity due to social media, as it is the standard format for avatars and thumbnail previews all around the web.

Effect : Because of its history it may add a vintage touch to a picture, especially if it is in black and white or in vintage colours. Apart from that, the most notable feature of this format is the perfect square. Horizontals and verticals don’t matter any more. The eye can no longer relate to what it is accustomed to and the reading becomes circular.

Positive points : It is well suited for symetrical subjects, for patterns, for round shapes. Or when you want to centre the subject inside the frame.  Fine art photographers use it a lot, maybe because of its perfect balanced shape, or because this kind of photography is not so interested in the real things in the real world and is too happy to express itself in a surface where the basic perception of the world, with its well organised space-time, is abolished. You may picture imagination, poetry, or organise a new world within the frame.

Negative points : Composition is more difficult, unless you centre the subject or deal with symetry. Its perfect shape may reveal imbalance in the subject more than with other formats. It is not suited if horizontality or verticality is significant for the story in the picture.

Case Study : In the picture above, The Faded Iris, the white and black patterns of its dead petals and the shadows on the table are displayed. The structure is diagonal in both directions. The reading cannot be vertical or horizontal, it is circular and the eye remains on the flower. The square format adds an impression of stillness to this picture dealing with death.

In the FieldHistory : It is the new movie format.

Effect : Horizontality is of primary importance. It gives a sense of scenery. Or a sense of time. The picture is not a picture but a moment in time, a sequence captured from a series of pictures or from a movie, even if it is not the case. Because of its widespread use in movies, our eyes have been used to recognising this code.

Positive points : A good format for landscapes, panoramas, ‘on the road’ stories.

Negative points : It is a very unusual format in photography and may be awkward with an inapropriate subject.

Case Study : In the picture above, the close up on the bent herb and the 16:9 format gives an impression of a forced horizontality, especially as the other herbs are vertical. Movement is implicit. The movie format gives a sense of time and we may feel wind is softly blowing there, or that the story will go on with a travelling movement of the camera and we will know what is happening here in this field. With another format, it would have been a still life photograph. But in 16:9 format, life is not still and we expect a motion. That will never come, because it is not a movie!<small>


As we saw the choice for a format or another is an important one, because of the natural shape of the subject or because of the story we want to tell. But as always, it is just a guide, and rules have to be understood to be forgotten. Behind these intellectual considerations, there is this magical moment of creation when you feel it must be done that way even if you can’t explain why. It’s in the eye, it’s in the feeling of an instant.

What’s your favourite format? How do you feel when your beautiful landscape is previewed in a square format on photography websites? How do you manage when you have not the choice because of the publishing medium (magazine page, book or CD cover, video slideshows etc)? Have you ever had to choose an unusual format?
