I am not sure if you are asking about a digital camera or a old style camera. If you want a good older camera that would be a Cannon as you can set the shutter speed on it. If you are talking about a digital camera then you should hold the shutter button down longer.
Most digital cameras, unfortunately, have some shutter delay. Shutter delay is the time between when the shutter release is pressed and when the image is actually captured. Shutter delay becomes more of a nuisance when you are taking action shots or even portraits. The split second difference could mean missing the winning catch at a football game or your baby�s first smile. The best way to find out about a camera�s shutter delay is to try out the camera at the store or review product review web sites. Many people will report on the shutter delay or offer tips for reducing it. One tip for overcoming shutter delay is to set your camera to continuous mode (if your camera has this mode). You hold down the shutter-release button as the camera takes a rapid succession of shots. Additional Tip. On most cameras press down the shutter half way so the camera focuses and sets up the picture (exposure etc), keep the shuuter release at this position until the subject is how you want it then press the shutter all the way. Most camera shutter delay is because it takes time to focus the camera and set up the electronics. The shutter will not operate until all this has finished. That why you can miss your shot.
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
The Shutter Speed. If the shutter speed is positioned at 2000 you'll have a very quick exposure, this is best used if its very bright outside. If the shutter speed is at 75, you'll have a very long exposure, best used if its cloudy or dark.
Shutter speed has a lot to do with your overall exposure. A higher shutter speed will decrease the light a lot. I was in best buy playing around with a camera and turned the camera shutter speed to 1/4000. After taking the photo, the preview was black. I realized it was because of how much higher I increase my shutter speed. Shutter speed also affects motion in a photo. A higher shutter speed will freeze all action in a photo a will less likely have a blur to it if you have a shaky hand. A lower shutter speed lets in more light while the shutter is will opened so the entire time that the shutter is open, the camera takes in all that light. Increasing chances of blur, you can also use this for crazy, funky effects! If your taking a picture of a waterfall with a low shutter speed, your gonna get a blur, which can typically look pretty epic sometimes too.
Shutter shack has some really good ones. See them at http://www.shuttershack.com/shutters/product.php?productid=16171
Nikon.
Phone cameras just do not have super high quality. The lens is very primitive and very little shutter control is available. The best advice is to have good lighting, then decent quality photos can be taken.
If you are looking for good quality and durable shutter the best material to look for is Alcoa vinyl.
Local camera stores will be happy to inform prospective buyers about the way shutter speed works and which cameras offer the best options. Additionally, you can read more about it online at a site such as this: http://www.digital-photography-school.com/shutter-speed
The kind of camera that you purchase will depend on what you want to use it for and your level of expertise. Most people will want a simple point-and-shoot camera. They want a camera that performs most of the focus, shutter speed, and exposure adjustments automatically. A more experienced photographer will usually want a camera that offers many manual settings, and are generally more expensive, and higher quality.
There are many different camera phones on the market. The one that offers the best camera quality is the newest iPhone 4 which will allow you to create the best images possible.
Cannon is sighted as being one of the best manufacturers of camera's and camera related items such as lenses. Nikon also makes a high quality lens system.
