The images below show how the most boring subject can become interesting with a small f-stop ( f/2.8)and lots of light and reflective surfaces behind it. This can be used to make amazing images with lots of sparkles. The mush at f/2.8 has shapes and these are indicative of the shape of the aperture and is known as bokeh. It can be used creatively to isolate a subject or add depth and dimensionality to an image. What is Bokeh in photography?īokeh refers to the aesthetic quality of the out-of-focus areas in a photograph, often characterized by soft, blurred circles of light. This can be a bit complicated to start with, which is why I always suggest starting with aperture adjustments only and when you understand that start playing with the shutter speed at the same time. To get a picture that looks the same, if you make the aperture smaller you will need to adjust the shutter speed or ISO to allow more light in. In the second, the F-stop is the same at f/6.3, but the bird has moved away from the heather and these are now just blobs in the background.Īperture size and shutter speed are linked through the exposure triangle. In the first, it is standing next to a piece of heather and this is all in focus. This can be seen in the two photographs of the grouse. The further away from the background an object is placed, the more blurry the background will appear. The effect can look even more defined if a longer lens is used, over 100mm it becomes really obvious, under 35mm and the effect is harder to make as you need to be close to the object or have a large distance between the object and the background. You don’t need to do anything other than realise that your shutter may stay open longer as you decrease the aperture size (increase the F-stop number) and you may need to use a tripod or support to stop shaking affecting the picture. You just need to be aware that as the aperture decreases the amount of light reaching the sensor decreases so you will need a longer shutter speed to compensate. This works well while you get to grips with what aperture does. This means you can adjust the aperture size but leave the other parts of the exposure to the camera to figure out. This will be selected from a round dial on the top of the camera body. To make things easier your camera will have aperture priority mode. The maximum aperture size will usually be found on the lens itself. Lenses, Background Distance and Setting Aperture Priority Modeĭifferent lenses will have different minimum and maximum f-stop and this will determine how much you can play. At f/16 the lavender field as well as the house and the fields beyond are in focus. The lavender fields at Snowshill in the Cotswolds provide the perfect example of how an aperture setting can alter the appearance of the landscape.Īt f/2.8 a narrow area of lavender is in focus. APERTURE f/2.8Ī landscape at f/2.8 will look very different from the same scene taken at f/16. In some situations, you will want the whole image in focus, such as a landscape and in others, you want just a single object in focus. The f-stop will control the depth of field – how much of the image that is in focus. They appear to be odd numbers, this is just because of the maths involved with working out the fractions! ![]() Just remember the larger the hole letting light in (aperture), the smaller the number. f-stop comes from what it is describing! The size of the hole or aperture is a fraction of the focal length of the lens. The aperture is known as the f-stop or f-number. The bigger the hole (aperture) the more light that gets in, the smaller the hole the lower the amount of light let into the camera. The aperture is part of the camera that lets light in and makes the picture. From understanding the basics of aperture size to exploring different camera settings and techniques, this post is the ultimate guide to mastering one of the most fundamental aspects of photography. In this post, we’ll take a closer look at aperture size, exploring what it is, how it works, and why it’s so essential for capturing great photos. This isn’t Photoshop magic, it can be done with your camera and a few settings. Think about those beautiful images where the bird is beautifully sharp but the area behind it blurs into a gentle colour. While the concept of aperture size may seem daunting at first, mastering it can lead to a vast improvement in the quality of your photos. One of the most critical aspects of photography is the concept of aperture size, which directly affects the amount of light that enters your camera and ultimately the quality of your images. Understanding the basics of photography is essential for any photographer looking to capture stunning images.
