Here are some more information for Zoom Digital:

The digital single lens reflex technology has improved the image quality. With the compact digital cameras, you have a lag time between taking pictures causing many photographers to miss some interesting shots. The flash time for recycling is also another concern with compact cameras. With digital SLR cameras, there is no problem with light sensitivity as there is with the compact cameras. The ability to take quality pictures without a flash is done with the SLR cameras.

Photographers that want to have different lens for capturing different images the SLR camera is ideal. If the user wishes to have a blurred background with a properly focused subject, the digital SLR camera achieves this purpose. The camera also offers a faster shot-to-shot time, which means the user can capture more actions shots as they happen. The ability to change lens to a telescoping lens means the user can zoom in on objects that are further away without disturbing the subject by moving closer.

Because the camera has different lens, the photographer can use the macro lens to magnify tiny objects so the detail can be seen. The SLR cameras are better for digital photography, but the size is larger than the compact cameras. The bulkiness of the camera does present a problem for some users, but it makes up for it in image quality and the ability to change lens and capture images in a natural way.

If your serious about wanting to improve your camera skills, but still retain some of the simplicity of point and shoot camera technology, there are plenty of entry level digital SLR cameras on the market. Improving your photography skills is an excellent response to the question: "Why Buy A Digital SLR Camera?".

Before buying a digital SLR camera, one has to consider the need for the camera and the amount of use the camera will receive. If the user is going to use the camera regularly, the SLR is the best camera to have for photography. There is going to be more editing of the images before the final proofs are ready for printing. All in all, the digital SLR is a great camera.

Digital Cameras

Today people are switching over from film cameras to digital models. The obvious reasons are the ease with which objects are framed and shot, pictures are stored, recorded, and displayed. To top it all you can download at the comfort of your home and print the pictures.

However if you are buying one for the first time, there are chances that you will be literally lost reviewing the specifications and features offered by the numerous brands out there in the market. Do you go by mega pixels or do you go by manufacturers or by price range or by….well, there are many more classifications possible. The following guide is prepared with the intention to help you arrive at a practical model of your choice.

Various Features

Weight

This factor depends a lot on the usage of the digital camera. You want one to carry around in your pocket or purse, go for the light weight ones. No doubt they are convenient, but the have tiny buttons, controls and dials which may make the handling a little difficult. The bigger ones weigh more and have more features too.

Resolution

Cameras are categorized as mega pixels of resolution. It narrows down the range of cameras and helps you sort out beginners, intermediate and advanced groupings from these. The range is 0.1 mega pixel to 18 mega pixel and some even more. The key to choosing the right pixel camera depends on how close you wish to get to target.
2 mega pixels and less- you get reasonably sharp images and enough details for prints of 8x10s and smaller. Prints are not of very high quality but suitable enough to be posted on emails and web sites. These cameras are inexpensive.
2 to 6 mega pixels- As the resolution keeps increasing in this range, the picture quality keeps getting better. You get sharper images all at an escalated price.Eg Canon PowerShot S3, Fuji FinePix V10 etc.

6 mega pixels and more- More aren’t always good. Keep in mind higher mega pixels mean larger image sizes, expensive memory cards, and take more space of your computer’s hard drive.Eg. Canon PowerShot Pro1, Canon PowerShot S80 etc.

Zoom
Optical zoom lens- Image gets magnified by lens-3x, 4x, 10x and more, however keep in mind that very long zooms are prone to camera shake. Use a tripod to cover up for this problem. A 3x optical zoom means it can make a subject appear thrice as close. An optical zoom produces the best quality images. You can’t get too close to the object, but then a photo editing software can help you crop the image. It gives better result than using the digital zoom.

Digital zoom is a simulated optical zoom; it enlarges only the central portion of the image. The lens is not used in this case. The digital zooming effect is given by software inside. The result is most often a blurry and digitized picture. You can use both zooming effects in cameras that offer both these features.

Lens

A lousy lens can spoil all that extra resolution and image processing controls. So, before you buy one assess the final image on a computer based on these criteria:

check the lens for overall focus and sharpness, whether corners are as sharp as in the middle

check for flaring, i.e. colored circles and reflections when shooting towards light source

check if the lens offer attachments, you can add wide angle or telephoto attachments to extend the focal length range

whether manual or electronic zoom control, manual zoom offers more speed and flexibility
Memory

Unlike the film cameras the digital cameras store images in memory. Thus each time the memory is full, you can download them and the camera is ready to shoot again. Memory is of two main types: built-in and removable. Most low end cameras have the built-in memory. Removable memory cards have the advantage of upgrading the memory, particularly useful when you are taking lot of pictures in one trip.

Flash Types

It all started with photographers igniting a tray filled with gunpowder to illuminate a scene. Today digital cameras come with built in automatic flash unit combined with a sophisticated light measuring and exposure control system. They are so convenient and easy to use that we often fail to notice it.

Digital cameras are specified by a guide number which basically gives the flash power. Higher the guide number, greater the flash’s useful range. With changes in sensor speed and /or lens focal length, the guide number changes. So manufacturers instead specify the flash’s maximum range with the assumption that flashes is fully charged and the lens aperture is wide open.

Some of the common modes:

Auto mode is well known! Cameras with red eye reduction mode first fires a short burst to close the subject’s irises then the main flash and finally the picture is taken.

Fill flash modes to fill in shadows.

Flash off mode to capture the object in natural light.

Night scene mode exposes the foreground subject without underexposure of background. For maximum flash flexibility select a camera with an external hot shoe.

Some models come with just the external flash units.

Some varieties have both external and built-in flash units.

Some very compact digital Camera models come with no flash units.

Focus Type

Most digital cameras have a combination of different focus modes. In the automatic mode, when you press the shutter-release button half-way down, the focus is locked. It is also confirmed by a change of color of the focus indicator.

The Auto focus is achieved in different modes. The most common of them is the single area focus mode. The focus is on the central area of the image you find on the screen. In the spot focus mode, the focus is precisely on the center area of the screen. For shooting slow moving objects you can use the continuous auto focus mode. Be aware of the huge consumption of power in this mode.
Manual focus- This feature allows you to manually focus on the portion of a scene which may or may not be at the center of the screen. Select the area to be focused by using one of the several focus area indicators by toggling a cursor button to achieve close ups and macro shots. Some models have the focus rings for manual focus, turn it till the subject is in focus.
Fixed focus- This feature can be used to your advantage when there is pre-determined distance between the camera and the object.

The various combinations of the focus types are:

Auto focus and manual focus

Auto focus and fixed focus

Auto, manual and fixed focus

Camera Type

Standard Point and Shoot cameras- Point and shoot models are available with basic features to the ones with advanced controls and options and excellent macro capabilities. The flexibility with which these cameras can be used like in situations where it is hard to frame the subject or shooting at waist levels makes these models much sought after. It is a silent performer ideal for shooting in locations where a loud shutter clack is not appropriate.

SLR/Professional- More interesting features like interchangeable lenses, flashes, sophisticated controls and other accessories, these models are specifically designed for photographers and professionals. Eg. Nikon D40, Nikon D40x etc.

Compact- The features are moderate, yet small enough in size to slip it in to your pocket before you go for the party. These models are comparatively higher priced than the similarly featured standard sized cameras. Eg. Canon PowerShot SD800, Kodak EasyShare V550 etc.

Ultra compact- With technology improving at a fast rate the size of the cameras is getting smaller and smaller. Cameras of the size of credit cards, slightly thicker shoot amazing pictures. No compromise on features like LCD screens (as small as 2 inch), optical viewfinder, good resolution (some with even 7 mega pixels), and good battery life too. Eg. Casio Exilim EX-S500, Samsung NV3 etc.

Battery

There are two types: rechargeable ones and disposable ones. Since digital cameras consume power very fast, especially if you are using a LCD, it is best to invest in the rechargeable ones. Some digital cameras come with AC adapters, if yours doesn’t have one, purchase one separately.

Some batteries are:

NiMH batteries are the most sought after ones today. They are rechargeable, last long, and come in various compact designs and no memory problems.

Alkaline ones are not rechargeable and don’t last long.

Lithium ion batteries are small and recharge quickly.

NiCad batteries if not charged properly can have loss of memory.

AC adapters enable you to keep shooting long after your batteries are dead!
Price

Luckily you don’t have to spend huge amounts to own one.

Low range

Even a couple of hundred bucks can fetch you a very good camera with video capabilities and nice zoom. And they are not the sub-par models of yester years. Eg. Nikon COOLPIX S5,Canon PowerShot G7 etc.

http://www.reviewgist.com/digital-camera-reviews?Price=0.01-to-237.49

Mid-range

A lot more features get added, more of mega pixels, and more powerful lenses are available in this range of cameras. Eg. Nikon D80, Nikon D200 etc.

http://www.reviewgist.com/digital-camera-reviews?Price=237.49-to-599.84

High range

These ranges of cameras are mostly for professionals with superb image rendering capacity and produce excellent photos. Eg. Nikon D2Xs, Canon EOS-1D Mark III Body Only etc.

What do they mean by "optical zoom" and "digital zoom?"?

I keep seeing advertisements for digital cameras,and the advertisement will have a statement like,"3X optical zoom and
4X digital zoom."
What do they mean by that? And what does that translate into in terms of the final print image?

Optical zoom is when you zoom in or out on your subject before you shoot it. In terms of 3x, your camera can bring your subject closer as much as 3 times of the local length of your camera - from 12 feet, it can bring to about 4 feet close. So, the higher the optical zoom is, the closer you can bring your subject (image) to your camera. Just like the zoom lens of the 35 mm SLR camera.
Digital zoom is when it can zoom the subject after you have shot it. Like an image of a whole body of a dog, you can zoom in to as close as to the face or nose. It's not actually zooming it, but more like cropping it in your camera instead of doing it on your computer. You will still lose some resolution as you crop it like you would in a computer - as you will see in your prints. You might say, it's not really that useful, if you can do it on your computer anyway. Why have it then, I think so it's a faster way you can download it to internet - it's already cropped and ready. So, don't mind the digital zoom when buying a camera, but do mind the optical zoom.
