![]() I have used many of these products or very similar ones personally. You've got to use the equipment properly and apply your own skills. Sometimes I recommend products that I believe will help you. My goal is to provide you with useful information that can improve your photography. Also, distances for subject and background have a big effect on what stays in focus and what doesn't. The photos are critiqued on how the lighting and composition are also considered when determining your camera settings.ĭepth of Field Comparison. Comparison of three nature photos, using the exact same camera, subject and background distances. A big list of other terms commonly used in digital photographyĮxamples of Depth of Field This article has several photo examples on the proper use of DOF to improve your photos. Technically, only one plane of the image can be in exact focus, but all distances lying within the DOF range are perceived as "acceptably" sharp.Īrticles Relating to What is Depth of Field This total region of adequate focus represents the depth of field." Ansel Adamsģ. What is depth of field according to John Hedgecoe? " Depth of field is concerned with the nearest and furthest parts of the subject which can be rendered sharp at a given focusing setting."Ĥ. is the range of distances in a photo where the image is said to be "sharp". In addition, there will be an area just in front of and behind this plane that will appear reasonably sharp. The DOF varies with the lens aperture, focal length and distances for subject and background.Ģ. " We can achieve critical focus for only one plane in front of the camera, and all objects in this plane will be sharp. It affects every single picture you will ever take. ![]() This is one of the most important digital photography terms to understand. Point and shoot cameras have small sensors and you have some ability to use either narrow or deep depth of field techniques.ĭSLR cameras, particularly those with full-sized sensors, give you the ability to get both deep and narrow depth of field results.ġ. The distance between the closest and farthest points that appear in acceptably sharp focus in a photograph. This is great for taking your basic snapshots, but you'll have very little ability to use shallow depth of field techniques. ![]() You can see that knowing what depth of field is can make a dramatic effect on your photography.Ĭell phone cameras use tiny sensors and will give you lots of depth of field. I attached an 85mm prime lens on a full-frame Canon DSLR and used a tripod to make sure the photos were composed in the exact same manner. Hold your mouse cursor over the image to see the exact same photo taken at f/22. Here's a depth of field comparison between using the widest and smallest lens aperture. Set aside a few moments to view several examples of depth of field in various photos and it will become second nature to you. Knowing what is depth of field and learning just a few composition tips, will help you enjoy your photography even more. This page titled what is depth of field is one of the basic photography posts on the this digital photography website. This large f-stop number gave me a large range of depth of field. I used manual focus and estimated a focus point between the distances of the two mannequins. In the third photo, I used a tiny lens aperture of f/16. So, controlling the depth of field combined with choosing what to focus on, change the photograph completely. In the first 2 photos I used this f/1,8 setting and took turns, focusing on each of my subjects. This gives the smallest depth of field possible. If it's the smallest number that can be used for a camera or it's lens, you call it wide-open. The little, white f-1.8 and f-16 numbers added to the photographs are the aperture settings I set on my camera for each one of the photographs.Īn f-stop of f-1.8 means a large lens opening was used. How was this done? I set my DSLR on a tripod and set up my male photo subject close to the camera and my female photo subject far from the camera. Only the depth of field and the focusing point were changed! Completely different photograph and they were all composed exactly the same. That means the range of things, close to far from the camera, that are sharply in focus, is big. The male mannequin is still recognizable and a bit of a distraction, but the main subject is clearly the woman. In the middle photo, the emphasis is on the female mannequin. If you did not have the other 2 photos to refer to, you may not have even known that there was a female mannequin in the background. In the first photo on the left, all of the emphasis is on the male mannequin head. There is nothing special about the photographs, but stay here with me for a minute.
