When you make the decision to purchase the best digital camera, you will find that there are many different makes and models, all containing different features and options, in many different price ranges. Most of the time, the sales person will advise you to buy the most expensive model claiming that it is what you need.
There are a few things that you should keep in mind before you go out shopping.
When the best digital cameras were introduced to the market, the choices were very limited. They did not have all of the features that you find today and they were easy to use.
The best digital cameras today come with a handbook filled with instructions. It can be maddening for someone who has never used one before. For some consumers, frustration sets in and the camera ends up in the closet.
Before you go shopping, decide on what you will be using your camera for. The prices can range in the thousands, so determining what your budget is before purchasing will help keep you on track. If your digital camera is for family related pictures, it is recommended that you purchase a camera up to five hundred dollars.
If you are an amateur photographer, and will be making prints of your photos, you will want to purchase a camera in the price range of six hundred to two thousand dollars. These cameras have features that you will need.
For the professional photographer, there is a large selection of the best digital cameras ever. These are not cheap, and you should expect to spend five thousand dollars at the very least.
There are several features that you should be aware of when you are researching for the best digital cameras. The number of pixels that the camera has is very important. If you are only printing standard size pictures, the pixel range of 640x480 will be perfect for you.
For larger pictures, more pixels will be required for a crisp clear picture.
It is also important to know what type of battery your digital camera has and how long it will last on one charge, as well as the size of the memory card and what type of zoom features it has.
There are two different types of zoom features. One zooms in on the photo and optically enlarges it, and the other digitally enlarges the pixels.
Make sure you are able to download the pictures to your computer. With Photoshop software, you will be able to enlarge them to any size that the software allows.
It is recommended that you buy the best digital camera with a higher optical zoom feature if you want to enlarge the optical magnification.
No matter which camera you choose to purchase, make sure that it has a flash memory feature. You may be able to purchase additional flash sticks, however they may not be compatible with your camera.
The best digital cameras use batteries to make them work. If you have a LCD screen, or use the zoom functions often, you will use more battery power. Rechargeable batteries will alleviate the cost of purchase batteries.
Summary:
There are many different types of cameras. However, the best digital camera that you choose should suit your needs, and finding one can be relatively easy if you know what to look for.
Which Is The Best Digital Camera
There are many factors summarized here, including performance and cost, that will determine whether you choose LCD or plasma for your digital signage display.
The Mechanics
A January, 2007 article on selfserviceworld.com described the differences between LCD and plasma in layperson's terms. In summary:
? LCD consists of two sheets of transparent, polarized material, one of which is treated with a polymer containing liquid crystals. The crystals interpret the electric current and control the light that passes through. Fluorescent tubes behind the crystals produce the light that passes out to the viewer. The crystals do not emit light so LCD screens use less electricity than other displays.
? Plasma displays use glass coated with bubbles that contain ionized gas in red, blue, and green subcompartments. A phosphorescent coating is applied to the glass and when electricity passes through the plasma it emits ultraviolet rays that show the appropriate color.
Performance
An oft-cited concern with plasma screens is burn-in. Depending on what you read, burn-in is either a serious problem or a minor one that can be easily remedied.
Burn-in is a term used to describe static images that become permanently visible after being displayed for long periods of time. Burn-in is not an issue with LCD displays but can become a problem with plasma. Burn-in is becoming less of an issue as digital signage display firms employ some simple techniques for avoiding it: ensuring images are frequently rotated, using more motion, and lowering contrast and brightness levels.
Lifecycle is another concern. At one time LCD had a longer life, but the life expectancy of LCD and plasma are now roughly equivalent, lasting about 50,000 hours each.
LCD units are lighter and use less power, factors which may affect your decision.
Contrast ratios (the difference between black and white) are much higher on plasma, which results in a clearer and brighter image. Plasma displays video images and fast motion better than LCD and offers a wider viewing angle, which can be important in retail environments.
Cost and Size
The deciding factor between LCD and plasma has often been cost. With the prices of large-format LCD displays dropping, cost is becoming less of an issue.
Size is an issue that ties in with cost since it is your budget that may ultimately determine the size of screen you choose. Plasma is generally available in larger sizes, although this is changing as LCD displays get bigger. Plasma does still tend to win out for larger displays - digital signage display designers tend to prefer it for displays over 50 inches.
How Can You Decide on a Digital Signage Display Format?
Both LCD and plasma offer some benefits, depending on your needs. When making a decision about your digital signage display, you need to take a good look at your budget and factor in the size of the display required
