Optical Or Digital Zoom? the Choice is Clear
May 26th
What is zoom?
Sometimes when you take a photo you need to focus on one area in the picture frame. For example when you take a portrait photo you want to make sure the object’s face fills the photo frame while when you take a group photo you want to make sure everybody is in the photo frame.
In to focus on that one area in the photo frame you can either physically move closer to the objects or use the camera’s zoom feature. When using the zoom feature the camera (mechanically when applying an optical zoon or electronically when applying a digital zoom) enlarges that area to fit the full picture frame.
There are two types of zoom – optical and digital (in older film cameras the only zoom option was optical). We will try to explain the differences between the two.
How does optical zoon work?
Optical zoom works by physically moving the camera’s lenses and changing the focal length. By changing the focal length you can make objects appear bigger and fit the full photo frame.
When satisfied with the zoom position you can shoot the photo by simply applying the shutter button.
How does digital zoom work?
With digital zoom you actually use built-in software in the camera to define a portion of the photo which you are interested in. Once chosen the software crops the rest of the photo and enlarges the area you chose to fit the complete photo frame.
The process of enlarging the zoomed area is also known as extrapolation. The camera software needs to calculate new values for the pixels that were cropped in order to result in a full frame photo. The downside of this digital process is that the enlarged photo quality is lower than the original photo taken.
It is easy to understand the quality loss using an example. Lets assume that you have a 2MP (2 megapixels) camera. You point the camera and decide that you want to zoom in 2X. You run the digital zoom software and choose a 2X zoom. To accomplish this zoom the camera crops half of the photo and enlarges the other half to create a 2X zoom effect. In the process a 1MP area is discarded (the half that is cropped). The other 1MP area is enlarged in a process that copies every pixel once to generate a 2MP photo. Although the new photo seems to include 2MP it really includes only 1MP of information that was copied once. The result is a photo with a quality equivalent to a 1MP photo.
If you have used a 4X digital zoom in this example the result would have been a photo with an equivalent quality of a 0.5MP camera (the zoom area is 1/4 of the frame – 3/4 of the frame would be discarded and the rest 1/4 would be copied three times to fill the frame).
Digital zoom significantly reduces the quality of the photo. If your camera does not include digital zoom you can always shoot the photo without zooming and then use a PC photo editing software to crop a portion of it and enlarge the rest. In fact using PC software is always the preferred method to built-in digital zoom since it allows you to try different zoom sizes, different zoom areas and different zoom algorithms while not losing the original photo.
So which one is better?
Optical zoom is superior to digital zoom. In fact from a practical point of view digital zoom should not be considered zoom at all. It is always better to apply digital zoom on a PC at a later time rather then when taking the photo using the camera’s built-in digital zoom. When using a PC different sizes can be used and different zoom algorithms that can result in better qualities.
Know your camera’s zoom
Some manufacturers claim the maximum zoom figure their cameras support without specifying if it is optical or digital zoom. This information is confusing as many consumers do not understand the difference between the two. For example if a camera supports a 5X optical zoom and 10X digital zoom advertising the camera as a “10X zoom camera” is confusing – 10X digital zoom can be done with any camera using simple PC software.
When buying a camera always make sure that you know what the optical zoom figure is and that it meets your needs. Ignore the digital zoom figure as it does not mean much and can not compensate for a camera with poor optical zoom.

The Mystical Zoom Effect Of Digital Cameras Explained In Plain English
May 25th
Most of the digital cameras within the mid-priced range include a 3x/4x lens – the first number refers to the optical zoom with the second number referring to the digital zoom. A few of the lower-end priced cameras have only a digital zoom, but their photos are rather dull and slightly fuzzy. The zoom effect in a digital camera is similar to, yet different, from that of a conventional camera. It brings distant subjects closer.
However, in a digital camera there are two kinds of ‘zooms’. The first is similar to that of a conventional camera and is known as the optical zoom. The second is the digital zoom, and is more interesting. It ‘simulates’ optical zoom by enlarging a portion of the image-that is the digital zoom selects a portion of the photograph and blows it up.
The zoom effect should not be confused with photo editing, where an image editing software is used to crop and blow a picture on a computer screen. Cropping a picture can refer to enlarging the main subject, or an area of choice – thereby eliminating the remaining parts. Another misconception associated with digital zoom is that it is very handy in capturing long distance images. Nothing can be more misleading. Optical zoom matters more in a digital camera.
The zoom that should be used for comparing cameras is optical zoom, and not digital zoom or total zoom. A camera’s quality depends upon the value of optical zoom; a camera with higher optical zoom is better than a camera with lower optical zoom. In fact, today the digital camera manufacturers have started using a new term – “total zoom.” This term only confuses the customer for there is nothing like total zoom. At best, it can be used to indicate the fact that a digital camera has both kinds of zoom – optical zoom and digital zoom.
Individuals who previously used the 35mm camera or an APS camera used only optical zoom. This uses the lens to bring the subject of the picture closer. Digital zoom are associated with the digital video cameras.
Many photographers do not really associate digital zoom as “zoom” in the digital cameras, as it only enlarges a portion of the image. In layman’s terms, the camera crops a certain aspect of the image, and then enlarges it back to size which causes a loss in image quality. But what it actually does is replace the image editing for cropping.
Another zoom effect that has been developed recently is the “smart zoom”. This particular zoom maintains the image quality by avoiding interpolation of the image. However, smart zoom works only if you select an image smaller than the full available image size.
Sometimes optical zoom is compared to resolution while buying a digital camera. Nothing can be more absurd. These are two different values and have no common link. Resolution is used to indicate the number of pixels in an image while optical zoom is used to define the lens power. It can neither increase nor decrease the resolution.
There is also a tendency today to disable digital zoom. Some photographers prefer to crop and enlarge an image on a computer screen. They don’t trust the camera to do it for them. This is not a good practice because it reduces the effectiveness of your camera.

Digital and Optical Camera Zoom: What’s the Difference?
May 6th
If you are new to photography, figuring out what zoom power you need and differentiating between the different types of zoom can be quite overwhelming. A number of new terms referring to zooming have been introduced lately in the marketing language of camera manufacturers, which only increases confusion. This article is aimed to bring a little more light into the problem and help you take a good decision when making the purchase.
Most mid-priced digital cameras have an incorporated 3x/4x lens. These numbers refer to optical and digital zoom. Most cameras have both optical and digital zoom, with the exception of a few low-priced ones, which tend to make dull and fuzzy photos. A digital camera’s zoom function is quite similar to the one of a film camera and does the same thing, namely bringing the subject closer. Anyway, in digital cameras here are two types of zoom, an optical and a digital one. Optical zoom is the one similar to the zoom of a traditional camera.
Digital zoom, on the other hand, simulates zooming by blowing up a selected part of the picture. It shouldn’t be mistaken with photo editing, which refers to applications used to modify the image after it’s been produced. Another common misconception about this type of zoom is that it is particularly useful for long distance photos. This cannot be farther from the truth. Optical zoom is much more important in a digital camera and it should be the one used as a criterion when comparing different models instead of digital or total zoom.
The quality of a digital camera is more dependent on optical zoom. To create even more confusion, manufacturers have begun to use the term of ‘total zoom’. In fact, there is no such thing. At most it can refer to the fact that a camera has both types of zoom functions, digital and optical. Traditional cameras like 35 mm or APS only had optical zoom. Optical zoom uses an incorporated lens to bring the image closer to the photographer.
Professionals associate digital zoom with digital video cameras. They don’t think of it as a real zoom for digital cameras because it just enlarges a part of the picture. In other words, it crops part of the image and enlarges the rest, resulting in a loss of quality. It works in the same way as the cropping and resizing options of photo editing applications. Another new term in digital photography is that of ‘smart zoom’. This type of zoom avoids interpolation and thus maintains the quality of the image.
People sometimes compare optical zoom to resolution when they purchase a digital camera. This doesn’t make any sense. The power of digital zoom and the resolution are two different things with no connection to one another. The resolution expresses the number of pixels in the picture, while optical zoom refers to the power of the lens. It has nothing to do with resolution and can neither increase it nor decrease it. Another tendency is to disable the camera’s digital zoom. Many photographers don’t trust this feature and would rather crop and resize the photo themselves on the computer. This is not a very goo practice as it decreases the camera’s effectiveness.

Digital Zoom Versus Optical Zoom
Apr 28th
Many digital cameras offer both digital and optical zoom. These two often confuse the average camera buyer, until you know what you’re looking at.
Optical zoom works much like the zoom lens on a 35 mm film camera. It changes the length of your camera’s lens and draws the subject closer to you. The optical zoom keeps the quality of the picture. Digital zoom works differently. It simply takes the picture and crops it then enlarges the part that is left. It causes the quality of the photo to be reduced, sometimes greatly.
What this means in terms of output is you may have a larger view of an object with the digital zoom, but chances are your image will become unfocused. Details will become lost. It is actually best to turn off the digital zoom feature of your camera if possible. This will prevent you automatically zooming in too close as the digital zoom is often an extension of the optical.
There are a couple of things you can do if you want a closer view of a subject but want the quality of your picture to still be good. Try moving in closer when you take the picture. Often only a foot or two will do the trick. If this isn’t possible, you can set your camera to take a picture at its highest file size. This will result in a photo that can be cropped to include only your desired subject, yet allow for an image that is still clear.
Digital zoom has its place. It can be used if the only destiny of your photo is the internet. Photos online can be a much lower quality in the camera and still appear acceptable when sent through e-mail or posted on a web gallery. If your goal is printing, however, seek a camera that has a greater optical zoom and turn off the digital zoom. Your pictures will be better in the end, even if they are not as close up.
