![]() Since this first pin is the furthest point from the focal point, this pin will have the most blur. (You can also change the blur amount by clicking and dragging on the partial circle outside the pin.) ![]() On the right, drag the blur slider until you achieve the desired amount of blur. Drag and drop that pin into the background, or the area the farthest from the focal point. When you opened the field blur window, Photoshop automatically placed that first pin for you. The blur pins tell Photoshop where to blur and how much. Inside the field blur window, you will choose what areas of your image to blur, while the blur tools on the right will control the amount and type of blur. With the image open in Photoshop, navigate to Filter > Blur Gallery > Field Blur. The level of blur increases with distance from the plane of focus - that is, either toward or away from the camera - but any objects that fall on the same plane as your subject should remain in focus. A lens focuses on a two-dimensional plane in space, with everything on that plane being sharp. As you work, consider how the blur in a real image looks. We should note, Photoshop techniques are almost always more work than getting the effect in-camera, but the field blur tool will quickly imitate the bokeh of a more expensive lens. You could spend an hour creating a detailed depth map, but the field blur tool lets you approximate this with much less work. In Photoshop, you have to tell the computer what objects are closest and farthest from the camera in order to get a blur that resembles the real thing and changes with distance - i.e., objects that are farther away from the subject should have more blur than objects that are closer. Of these, getting the effect of distance correct is perhaps the most important. After trying everything from detailed selections to a full-on depth map, the field blur tool offered the best, most realistic results in the least amount of time.īokeh is a tricky thing to try to imitate in Photoshop because true lens blur is based on many factors, including the focal length of the lens, the shape and size of the aperture, and distance from the subject. Photoshop includes a handful of different options to blur a background, with each option offering a varying level of control - and level of difficulty. One of the easiest ways to go from blah to blur, however, is by using Photoshop’s field blur tool, which creates realistic background blur without requiring you to waste hours in front of your computer. The program includes a number of different tools to selectively blur the background of a photo, along with many options for controlling the type of blur. But even without a high-end camera or portrait mode, you can still create beautifully soft backgrounds in Adobe Photoshop.īeyond simply granting you an ability you may have not had access to in camera, choosing to add blur in Photoshop can give you more control and flexibility over where the blur is applied and how it looks. The effect is popular for portraits, and is emulated - with some limitations - by the “portrait modes” now found on many smartphones. Fitbit Versa 3īackground blur, often called “bokeh” after the Japanese word for blur, is generally associated with high-end cameras with wide-aperture lenses. Increasing the shutter speed can help you capture the subject in sharper detail. If your subject is moving when taking the pictures and the subject appears blurred, then the selected shutter speed may be too slow. Use a shutter speed of 1/100 sec or faster when shooting with a 100mm focal length, and so forth. The generally accepted rule to prevent blurring is to use a shutter speed as fast as "1 divided by the focal length." For example, this means if shooting with a focal length of 50mm, then you should use a shutter speed of 1/50 sec or faster. Even when shooting stationary objects, it is recommended that the camera be mounted on a tripod or placed on a stable surface when shooting in these situations.īe aware of the shutter speed when taking pictures. With slow shutter speed and high zoom lenses, camera movement that would ordinarily not be noticeable becomes more apparent. Keep in mind, however, there are times when using the SteadyShot® technology will not be as useful and using the flash may not be practical such as when shooting with long shutter speed or using a lens with a high zoom capability. Also, if shooting in low light, using the flash may help. When holding the camera, it is recommended that the SteadyShot function be turned on to reduce the effect of camera shake. It occurs when the camera is moved during the exposure and results in a shift or ghost-like image of everything in the picture. Camera shake is the cause for many blurry and unclear pictures.
