How to Control Depth of Field With F-Stops in Photography

Oct 23,  · When shooting on a camera, achieving good depth of field starts with your f-stop. Setting your f-stop to a lower number will make your aperture wider and give you a shallower depth of field (areas not in focus are blurrier). Setting your f-stop to a higher number will do the opposite; more of your image will be in focus. If the lens focal length is 20mm and the aperture diameter is 10mm, then f-stop = 20mm/10mm = 2. This is denoted as f/2. The photographer controls the f-stop, which determines the depth of field and how much light enters the lens. The larger the f-stop value, the less light enters the lens, over a .

A common term in photography, depth of field is important to consider when creating any photograph. It is used at varying degrees to place either everything in the image into a sharp focus or to narrow the focus and highlight a subject, allowing other elements to be blurry. Photographers use depth of field to create certain effects and draw fielr viewer's attention to particular elements of the scene. It is important to understand how the aperture setting on your camera, the focal length of the lens, and the photkgraphy of your subject affects a photograph's depth of field.

Depth of field is the amount of your image before and beyond your focus point that will be in focus. You should understand what depth of field is because it will tell you whether or not your subject and background can be sharply focused at the same time. Depth of field is determined by three primary factors:. While the camera can actually only focus on one tiny point in space, the depth of field determines how much of the image is in "acceptable focus" to the human eye.

The primary control of depth of field is the aperture, or f-stop, setting on your camera. Aperture describes an adjustable opening inside your crsate lens that controls the amount of light striking the film or digital sensor. Bow the size of the aperture changes, the angle of light striking the film or sensor also changes.

It is this angle change—much like eyeglasses change the angle of the light—that creates a change in the depth of field. Aperture is measured by f-stops on your camera controls. F-stop settings represent a ratio derived from the size of the lens opening and the focal how to get on twitter. Because a smaller aperture limits the amount of light entering the creae, a large f-stop smaller opening also requires more light to depyh expose an deptj.

This means that:. The focal length of your lens plays i big part in determining the depth of field DOF for your images crete well. Think of your lens strength as a limiting factor for your aperture capabilities. The higher the magnification factor, the smaller the depth of field will be, even with large f-stop settings.

The depth of field progression for a 70 to mm lens:. This effect is especially pronounced in macro photography where the close proximity to the subject and high focal photofraphy result in depths of field that are sometimes less than creaye inch.

Much like lens strength, subject distance plays a big part in determining the possible depth of field in fiwld image. The closer you are to your focal point or subject, the less depth of field is possible. To illustrate this effect, depfh your hand at arm's length in front of your face. Even when focusing on your hand you can probably see a good bit of the surrounding environment in a reasonably how to say goodnight in german language focus.

How to create depth of field in photography move your hand toward your face until you reach the half-way point. Notice how much less of the area surrounding your hand is in focus. Continue moving your hand closer until it is as close as your eyes can focus on it and notice that very little of the area surrounding your hand can now be seen.

This photographyy effect occurs with your camera lens. It is easy to do a test so you what editing software does ijustine use experience how to control the depth of field hoq get a visual for its effect on your photographs.

To do so, it is best to use a tripod as shutter speeds will vary. Compare the three photographs side by side and notice how more of the scene falls into focus as you decrease the size of the aperture opening use a larger f-stop. Also, notice that your shutter speeds tk slowed down with these larger f-stops.

Some camera lenses will have smaller and larger f-stops than the examples photographhy. Use the smallest and largest available on your lens to get the full effect of depth of field.

Take this new knowledge with you and consider it in every photograph you take. It will give you greater control of your images and can be used for various effects.

Aperture set at f/18 to give maximum depth of field and long exposure of 5 seconds to give "creamy" effect to water. The moss-covered rocks in the nearby foreground, the winding stream and then the more distant cascading water create a pathway for our eye to travel. Landscape photographers often use large f-stops to increase the depth of field in a scene. Portrait photographers often use small f-stops to decrease the depth of field in a scene, drawing the viewer's focus to the subject's eyes and face. Note that with large groups, you need a depth of field that will get every person in focus.

By focusing on one area or subject in the shot, a photographer can essentially control what the viewer sees in an image and how they see it. In other words, depth of field is like a superpower. Mixed with good photo composition, it can take your photography to a whole new level! There are two ways to achieve depth of field in your images: you can create depth of field while you are shooting or you can edit your photos to mimic depth of field in the editing phase.

Before you even think about pressing the capture button, there are a few things you need to have in order for achieving depth of field. First, you need a defined focal point. This can be a person or object in your photo that you want to be in total focus. When shooting on a camera, achieving good depth of field starts with your f-stop. Setting your f-stop to a lower number will make your aperture wider and give you a shallower depth of field areas not in focus are blurrier.

Setting your f-stop to a higher number will do the opposite; more of your image will be in focus. If you find that you need more of your subject in focus, increase the f-stop until you like what you see, then re-adjust the ISO and shutter speed.

Another great way to gain perspective while shooting with depth of field in mind is to move around your subject. Try taking the photo from higher up, from the ground shooting up, and other angles that can add intrigue to your shot.

That means shooting with your subject directly in front of the background, such as a wall, will be harder to achieve depth of field. After all, it's all about depth. That means positioning your subject with some distance between them and the background. As technology advances, so does the quality of our smartphone cameras. Depth of field is easy to achieve on all kinds of mobile devices by simply tapping the area on your screen you want to use as a focal point.

This will keep the subject sharp and in focus and blur the background with a single tap. Some advanced smartphones even offer Portrait Mode. It lets you adjust the depth of field while shooting to make the background as blurry or clear as you want, keeping your subject in sharp focus. Funky Focus is a powerful tool that makes adding depth of field to your images a snap! To use it, select Funky Focus from the Edit menu on the left.

Whatever shape your target is, you can adjust it by clicking and dragging the blue circles to make the in-focus area wider or shallower. Once your target is adjusted where you want it, you can use the sliding scales to adjust the Blur amount more gives you a blurrier background, less is more subtle , and Opacity of the blurred portions. Keep in mind when adjusting the sliders that you want the effects to be subtle. You do not want harsh lines coming directly in contact with fully blurred edges - this will make your photo look overly processed and unnatural.

Always add a little at a time until you feel the effect is really working to your benefit. Another amazing tool for adding depth of field is the Blur Tool. This tool gives you more control and versatility than the Funky Focus tool - it just depends on how meticulous you want to be and how much time you have!

If you are wanting to manipulate specific part in your photo and you want more control, this is a better tool to use for you. To use it, click on Blur in the Edit menu on the left. Once you're in the Blur tool menu, click on the Paint tab next to Adjust. You will notice that when you select the Blur tool, the entire image automatically blurs. This is okay. When you select the Paint tab, you can paint over the areas of the image you want to remove the blur from. If you mess up, just undo the paint stroke by pressing this shortcut on your keyboard.

You can see in the image above that the edges look very unnatural. That is okay at this stage. After you get your edges how you want them, click over to the Adjust tab to decrease the Blur Amount. See how easy that was? Using the Blur tool in paint mode gives you total control over the focal point of the image. Try experimenting with this technique during the shooting phase and also the editing phase. Please enable JavaScript to view the comments powered by Disqus. New to BeFunky?
