How A Digital Camera Works

Paul Stevens — Tue, 10 May 2011 09:59:03 +0000

An electronic digital camera works a lot like film camera in that light comes in through the lens and it is captured to create a picture. The way the image is captured is what makes an electronic digital camera different than a film camera. With a film camera, you press the shutter button which opens the shutter letting in the light. The light entering the lens is exposed to the film and causes chemical reactions within the film to create your photograph. In a dslr camera the picture is captured with an image sensor that converts the light rays into electronic signals which are then kept in a file in the buffer memory.

The light detector or image sensor is known as charged couple device (CCD) and it is comprised of individual light sensitive picture elements popularly known as pixels. Digital cameras tend to be measured in megapixels or millions of pixels. A camera having a 3000 x 2000 array of pixels within the image sensor would contain 6,000,000 pixels and is known as a 6 megapixel camera. When the light hits the CCD it breaks it down into the millions of pixels and measures the amount of light and color to generate a number for each pixel. Your digital picture is really a long string of numbers that is stored at a file in memory. The LCD screen on the back of the camera shows you the picture which the CCD is capturing.

Digital photographs have to be compressed or the file size would be enormous and fill up way too much memory. The most frequent compressed format is JPG which stands for Joint Photographic Experts Group. The higher the amount of photo information is kept the better the picture quality and the bigger the file. The more compressed the photo is, the lower the quality and the smaller the file size. The smaller file size makes for shorter load time plus you may store more photos in memory. One does sacrifice quality however.

The fact that digital images are stored digitally means they easier to keep, share and manipulate. If you open up a picture inside an editor such as Photoshop, you are able to change the quality of the photo by simply clicking on a setting. Once you do that it changes the numbers that the pixels are storing to generate the effects. For instance, if you wish to make the picture 10% brighter, the image editor would alter the pixel numbers by 10 percent to show increased light or brightness.

Some digital camera models have built-in effects and you may make a photographic effect in the camera immediately after you take the picture. Something you simply can\'t do with film cameras.

There are many more digital camera features that you should review before making your decision, but for now this is plenty to discuss. Look for other articles reviewing more digital features.

Most photographers are happy to let their digital camera automatically select exposure control. This means that the camera will automatically select the exposure control and/or the aperature setting. If you grew up setting these controls yourself on your film camera, or of manual override of those controls is important for your photography, then be sure to look for manual override on the feature list for your camera possibilities.

A zoom lens is actually several different lenses or lens elements. With multiple lens combinations, the focal length can be varied resulting in bigger or smaller images appearing on the film or digital imaging surface. A zoom feature can help you frame a shot to make it appear artistically unique, and it also brings you closer to your subject. With a good camera zoom, you can quickly switch from a wide angle to a close - up shot without changing your location. A standard focal length is typically about 35mm. This gives you a generic \"snapshot\" view of your subject. Common zoom ranges of 3x will take that focal length up to 105mm. This range is suitable for most hobbyists or casual photographers. However if you need even more zoom, or would like to do wide angle photography, look for ranges of 24 or 28mm on the low end, to

If you are wondering what the difference between optical and digital zoom is, it\'s pretty basic. Optical zoom will actually give you more detail about the subject matter when the zoom is employed. The lens elements bring you closer to your subject allowing more detail to enter the camera\'s lens. With digital zoom, however, the image that arrives is enlarged, but no additional information is being gathered. if you want the best detail or are interested in having larger format prints made from your photos, always be sure to take your photos using the best optical zoom available to that frames your subject well.

Hybrid Cameras Explained

Paul Stevens — Mon, 25 Apr 2011 09:58:48 +0000

Hybrid cameras, also known as mirror less cameras, are a new strain of camera that combine the compactness of your compact digital camera together with the image quality of a digital single lens reflex camera. The modern hybrid cameras don\'t have a single lens reflex mirror removing some of the bulk of a DSLR, but have a larger image sensor than your standard compact digital for better photos. A hybrid camera also does not have a normal viewfinder as in a DSLR, but rather uses an LCD screen or an electronic viewfinder that can be purchased separately. The hybrid cameras have interchangeable lenses similar to a DSLR, making them versatile enough to get many types of shots. They also take incredible HD video in 780p or 1080p format.

Hybrid cameras are the answer to that middle market of consumers who do not want to invest in high end DSLRs, but want to get excellent quality pictures than a compact digital. The hybrids are compact enough to carry around without difficulty. On many models, you are able to instantly record HD video without dealing with a menu. Most models run in the $300 - $1,000 range, which makes them very affordable to many people.

Olympus and Panasonic use what\'s known as a micro four thirds format for interchangeable lenses. It is an attempt to come up with a standard format for digital camera lenses to make it possible to change with advanced DSLR lenses. Micro four thirds refer to the ratio of the image sensor, which is a 4 X 3. This size is smaller than an ordinary 35mm, but about 10 times larger than a regular digital compact. The increased size and quality allow the photographer to shoot in lower light without worrying about graininess connected with smaller image sensors.

Many major camera brands have come out with their own version of the hybrid camera. Panasonic led the way with the Lumix G1, then came Olympus with the PEN series. Sony came out with the NEX 3 and 5. Nikon and Canon have promises to come out with hybrids very soon.

With all the hype surrounding the modern hybrid cameras, it remains to be seen if the marketplace for this kind of camera will take off. Sales have steadily increased since 2008 and it\'s predicted to take off by 2012.

Hybrids offer the best of both worlds. They are compact enough to cart around easily and powerful enough to take great photos.
