First of all, you are throwing away pixels that you will never be able to get back. While doing this reduces image resolution and file size, it is often not a good idea to switch to non-native aspect ratios. Hagia Sophia, captured in camera’s native aspect ratio of 3:2 All other options, such as 5:4, 1:1 and 16:9 are not native to the camera, which means that choosing any of them will result in cropping part of the image. Note that the first two options are both 3:2 (FX 36×24 and DX 24×16), because it is the native aspect ratio of the sensor on this camera (the second option is provided to crop the center part of the image to simulate Nikon’s APS-C / DX camera sensors). Some cameras, however, provide the ability to choose different aspect ratios to photographers.įor example, the Nikon Z7 allows choosing between the following: This is why paying attention to aspect ratios when composing and framing your shots is very important – always make sure to provide enough “breathing space” around your subject if your end goal is to have more cropping options later.Īs I have already mentioned earlier, the aspect ratio is often determined by the camera’s image sensor, which is its “native aspect ratio”. If I had captured this image in its native 4:3 aspect ratio to begin with, I could have avoided this problem. Take a look at what changing to these aspect ratios will do the above image: The same image showing what happens to framing with 3:2 and 4:3 aspect ratiosĪs you can see, while 3:2 might work out in the above case, 4:3 is definitely not a good option, since it is cutting into the foreground structures. Unfortunately, since the top and the bottom parts of the image were cropped out (even when shooting RAW), I will have to crop the sides of the image quite a bit to get to 3:2 or 4:3. When I was using the DJI Mavic Pro drone in Cappadocia, Turkey, I forgot that I set the camera to capture images in 16:9, so I ended up with a bunch of wide images like the image you see above. The same goes for choosing extremely wide aspect ratios, where the camera crops the top and bottom of the frame, as in the image below: This image in was captured in 16:9 aspect ratioĬappadocia, Turkey. When aspect ratio is expressed in decimal numbers such as 1.50 or 1.50:1, it ignores the orientation of the image. For example, 3:2 indicates a horizontal image captured in landscape orientation, whereas 2:3 refers to a vertical image captured in portrait orientation. Lastly, when aspect ratio is expressed in two numbers separated by a colon, the first number typically refers to the horizontal side of the image, whereas the second number refers to the vertical side. When looking at image dimensions in pixels, a 6000×4000 image from a 24 MP camera also has the same 3:2 aspect ratio. For example, the aspect ratio of 3:2 could translate to an image that is 3 meters wide and 2 meters high, as well as 3 feet wide and 2 feet high. It is important to note that aspect ratio does not represent the physical size of an image, or its dimensions in pixels – it refers only to the relationship of its width to its height. Nikon’s CMOS sensors have a 3:2 aspect ratioĪs discussed further down below, some cameras allow choosing different aspect ratios through the camera menu, providing cropping options other than the native one of the image sensor. All modern full-frame and APS-C DSLR cameras have 3:2 aspect ratio sensors, whereas 4:3 is a popular choice among smartphone, Micro Four Thirds and some medium format camera manufacturers. The most common aspect ratios of modern digital camera sensors are 3:2 and 4:3. The aspect ratio is often determined by the form factor of the camera’s film / imaging sensor, which is practically always rectangular. Similarly, an image with a 3:2 aspect ratio would be represented by 3 equal size units for its width vs 2 units for its height, as shown below: For example, a 4:3 aspect ratio would consist of 4 equal size units for its width and 3 equal size units for its height. You can easily visualize any aspect ratio by allocating units to the width and the height of an image. Some even prefer to express aspect ratio as a decimal, followed by a colon and number 1, such as 1.50:1. It can be expressed as a number followed by a colon and followed by another number, such as 3:2, or by a decimal number such as 1.50 (which is simply the long side divided by the short side). In photography, aspect ratio represents the relationship between the width and the height of an image.
