This effect (with the blurring known as bokeh) is used quite commonly in portrait Photography as well as wildlife photography and helps to increase the prominence of the object of interest within the image while minimising the distracting effect of the background.

Most cameras have a portrait setting which will help to achieve this effect. They do this by maximising the aperture size of the camera lens (letting in more light) which in turn has the effect of minimising the depth of field (a term used to describe how much of the image in front and behind the object of interest is in focus, the smaller the depth of field, the smaller this distance and the more blurred the foreground and background will be - the Wikipedia page on bokeh linked to below has some very good examples of this) so that when you focus on the point of interest, the fore and background will be blurred.

If you have an SLR camera (one with a detachable lens) you can manually achieve the same effect by maximising the aperture (i.e. setting the lowest f-stop number possible). You can usually do this by setting the camera to manual or aperture priority mode (which will let you alter the aperture size yourself, rather than the camera choosing a value).

Other techniques you can use to maximise this effect are to ensure that the object of interest is as far away from the background as possible (may be impossible with wildlife photos, but you can always ask people in a portrait to move!).

The effect can be further emphasised by setting the camera to the highest zoom possible while standing as close to the object of interest as possible.

Another option is to "cheat" and use image editing software such as Photoshop to apply a "blur" filter to your image background although this does not achieve quite the same effect as that produced by a camera as the blurring will be uniform across the background whereas in a real photo the blurring will vary depending on the distance of the background object from the point of focus.

How do you get a clean picture on a digital camera?

My guess is you're asking about motion blur. Try these effects, depending on the speed of subject motion and the effect you desire. 1) use a slow enough shutter speed to induce motion blur. You may need a tripod to steady the camera if it gets to be too slow to hand hold. Subject in motion will blur to some degree. 2) Using an example of a fast moving car: Pre-focus on the spot where you want the subject to be when you take the shot. You will have to consult your camera manual on how to do this if it is an autofocus model. Begin following the moving subject, keeping it in the viewfinder. Just as it approaches the predetermined spot, take the picture, and follow through a bit (don't stop following the subject when you press the shutter release). The car will be relatively sharp while the background will become a blur.


What is photograph blur?

Blur in a photograph can be good or bad, depending on whether it's there on purpose or not. Usually, a photograph is blurred when either the photographer or the subject moves while the camera is still recording the picture. If the photographer moves (sometimes the camera moves slightly when you press the shutter release button), the blur that results is said to be from "camera shake." Modern cameras have some form of image stabilization to counteract camera shake and therefore reduce or eliminate blur. If the subject is moving, the only way to freeze that motion is by using a fast enough shutter speed. A shutter speed of 1/125 sec. may be enough to capture a child running around but you may need a shutter speed of 1/2000 sec. to freeze the motion of a race car. However, blur can also be good and photographers will use a shallow depth of field to introduce blur into their pictures. Why? To isolate the main subject from a distracting background. This technique is very effective when taking portraits.


What does a pinhole camera look like when its done?

Yes, however you are restricted as to what you can take pictures of. Pinhole cameras must stay on a surface while taking the picture (as to not blur the image), unless you want to produce an image with motion blur you are unable to take pictures of any moving subjects, and the images are not digital; meaning you need to develop the image using chemicals and a dark room.


Will your tattoo Blur?

It will blur if you rub vasaline or other jelly on it early on, otherwise only if it is a bad job and gets infected, otherwise it shouldn't do. If you want to be sure your's won't make sure you go somewhere well known and safe so that your tatoo does not blur.

Why does your vison blur in and out?

because you try to focus on an object either in the foreground, middleground, or background. Same thing with a camera. So, if you focus on something in the foreground, the background will be blurry, and vise versa.


What is the meaning of phrase jumped out?

The usual meaning of the phrase 'jumped out' is when an image or an idea suddenly becomes clear to you. Have you ever looked at an autostereogram (a 'magic eye' picture). You look and you look - and you see nothing but a blur of colour. And then suddenly the picture 'comes'.


Why do JPEG picture files always blur when you save them?

The lossy compression in the JPEG files generates a blur effect near the edges in the image. The stronger the compression, the more visible the blur effect.


How do you blur in Photoshop elements?

You can easily add blur using depth of Field in Guided Edit or from Filter > Blur > Gaussian Blur, Motion Blur... When using blur filter from Filter menu first duplicate layer with image, apply blur filter then create layer mask and use Gradient Tool on layer mask (set foreground background colors to black/white) to restrict blur only to some areas of the image.


Does the shutter speed affect the quality of picture?

No, but it does change whether motion in your photo will blur or not.


How do you set desktop backgrounds so as not to blur when stretched?

If you got it from google then you need to enlarge it but otherwise you need to tile it or center it. The only reason pictures appear blurred when they are stretched on your background is because the picture you have chosen is small. You have to chose a picture with a higher resoloution. Pictures that are over 200 pixels are the best.


the word blur can be used as what parts of language?

A noun or a verb. If there is a blur on the screen, that's a noun, but if you blur the screen by adjusting the tracking, then that is a verb.

How does shutter speed improve photographs?

It doesn't necessarily inprove your picture. The higher the shutter speed, the less light, also the blur in a photo. A higher shutter speed will freeze a photo. A lower shutter speed will blur most motion and will increase chances of blur.
