Digital Camera Shopping

Shopping for a digital camera is a real challenge. Apart from the fact that there is such a wide variety to choose from, there is a ~ surprising lack of knowledge about the role of salespeople in the typical large electronics chains.

To make it easy, I seek to break the important features to offer a few tips for places to shop, get honest comparison, and you my personal recommendation based on personal experience.

The only thing that has not changed in the photography field is the adage "You get what you pay for." There are many inexpensive cameras available these days, and they look very impressive, but take very bad pictures.

How do you see the last case, imagination and sense of the seemingly endless stream of jargon? It really is not as difficult as it seems. There are a few important features, according to which one in a camera that you will quickly make, size up the field.

RESOLUTION
>Camera resolution is specified in "megapixels," and refers to the number of dots that make up an image. (A pixel is a single dot of color on a computer screen or printed image, and a "megapixel" literally means an array of 1 million tiny dots.) Obviously, the more pixels you have, the sharper and more detailed your photos will be. A 6 megapixel camera will have a resolution approximately of 2800 X 2200, for example.

If you compare picture resolution to the typical resolution from a computer screen, one might wonder what the big fuss. Why is a camera that images in 2800 X 2200 is if your screen resolution is only 800 x 600? The answer comes down to process. Suppose you are on the beach, and you see a baby on the shore throwing crackers into the air to feed the seagulls. If you take the picture, let us say 100 meters, the boy and the birds are a very small part of the picture.

In the old days we had only the harvest photo belowand are an extension of only the boy and the birds. If you shot the photo with a 1-megapixel camera, the cropped area only 200 x 160 pixels in total (about the size of a typical display on a website!). If you try an image that small to be on an 8 "X10" sheet, enlarge photo print look like it would be of hewn stone, the color was done, because you only have the same 200 x 160 pixels, so that each takes only enlargement is more space on the paper.

(If you ever had aMagnifying glass to closely look at a picture in a newspaper printed, you see the same effect: instead of "closer" to see every detail, a series of large colored dots.)

If the photo was taken with a higher resolution camera, it still would be able to harvest enough pixels in the image and have it easily, without looking "pixelated print."

QUICK NOTE:
Higher megapixels = Sharper Pictures and a better opportunity to harvest and. Edit

ZOOM
There are two types of advertising in digital cameras zoom: digital zoom and optical zoom. Optical Zoom zoom is the same, that since about on 35mm SLR cameras and video cameras for generations: They increase and adjust the lenses to get closer to the image.

"Digital zoom" is useless. Period. If it is destined, or someone trying to see them sell as a feature to ignore it. Cheap cameras use this technique to make it appear that they do have zoom function. The truth is that you can zoom Digital zoom when you look at a picture on the computer in a graphics editor: If you do not want the picture "" They just beat him so one pixel now takes up more space on the screen.

Optical zoom is a great feature, and even a small zoom factor of 3x (makes the subject appear as if it 3 times closer) makes a big difference when composing a shot.

QUICK NOTE:
Optical Zoom = Good.
> Digital Zoom = Nothing. They (the same on your PC is not in a graphics editor.) Can

Lens & Sensor Size
A larger CCD means a defined image, and a better opportunity to take photos in low light conditions. You'll notice there are three dominant types of cameras on the market: portable cameras with a lens that is maybe 0.25 "in diameter, mid-range cameras with a lens that about 1" in diameter and large cameras with lenses which are 1.5 "or greaterdiameter.

Portable cameras generally have no optical zoom capability, and are fine for outdoor pictures in sunlight. They are great for tossing onto a purse or pocket and snapping some pictures while out at a theme park, but forget about trying to take a decent indoor picture.

Mid-range cameras are great for all-purpose pictures, and generally have an optical zoom and offer features like red-eye reduction and "macro" mode to take close-up photos. (The lens assembly on many of these Units are often at the camera when it is turned back, with a height and is similar to the portable cameras.) You Outstanding Outdoor taking pictures, and cover most indoor pictures without problems. They do not do it so well in low light situations and in school plays or concerts.

Large cameras approach the control and flexibility of 35mm SLR cameras. In automatic mode, they work just as easy as point-and-shoot-brothers, so that everyone can use it.For experienced photographers, the ability to manually control the parameters such as the f-stop, aperture and film speed are a big plus point. These cameras take extraordinary shots in all conditions.

The next step beyond these are true costs to 1000 dollars and professional cameras What do you get in this price class is the possibility of standard SLR lenses and crazy-high resolution photographs for use are printed on posters.

For consumer-level cameras,Portability and quality are two things that are always in opposition. A camera with a small lens is definitely easier to cart around, but they seldom take good interior shots. A camera that takes great indoor pictures have to be treated with care and more likely to provide fingerprints to the larger lens to be able to use it.

QUICK NOTE:
Small lenses and Hardy = Portable / Poor picture quality and the inability to make low-light photos
Large = Better Optics Lenses& Image Quality / softer and less mobile

MEMORY
Digital camera memory cards used to hold pictures. Think of this as "digital film." Memory cards are rated in megabytes (MB) or gigabytes (GB), and the larger the memory card, the more pictures you can deliver. The number of images depends on the fit on a card, the resolution of the camera, so you usually have a table on the package that will tell you approximately how many photosfit on the media at a given camera resolution.

For the old-school photographer is confusing, since conventional film is sold in rolls, where each role a certain number of pictures instead. When to go to pictures to shoot the film's photographer, the number of pictures that were taken and buy enough film for the organization to appreciate.

Digital film is also different in that it is reusable. If the media is full of the images are easily downloaded to a computerthen the media is they cleared for use again. Another important difference is that digital film can hold much more photos than a traditional role of the film.

Purchasing memory for a camera is usually a one-time deal: instead of buying films any time you want to take pictures (and that you have enough roles!) You just buy a media card when buying the camera.

The first time you see an entire ship filled with memory cards, it seems thatchoosing one is a hopeless task. Fortunately, this is usually the easiest decision to make, and also the very last question you ask after you have settled on a camera. The simple approach is to figure out how many pictures you want the camera to be able to hold before your memory is full, then ask the salesperson which card they would recommend that will hold that many images.

This is one thing that even the dullest of sales people always know!

DOCKING AND PRINT
Many cameras are now coupled with printers, so you can simply plug the camera into the printer and get paper to print. This is very practical, and down he proposes to Walgreens or Walmart to have them print your digital photos. Be aware that it can be quite expensive as the photo paper and ink cost you much more than the supply for a standard printer.

I'm not a great photographer, and nearly 90% of what I shoot, is not worth the pressure, so I prefer justdownload all my pictures on your PC, harvest, and they fit until I have a couple I like, and then either print them on my normal printer or send it to Walgreens for printing have.

On a per-print basis, it is more expensive, your photos are printed in a lab, but when you consider that your prints are on photo paper to get longer tenable, and the colors are more vivid than all but the most expensive local printer they are worth it. For me, the only time I would like to print a photothat is if I want to frame it, and I am happy to pay the buck or so for real photography printing.

THINGS TO TRY when shopping for a camera

- Go to a store with demo cameras work and try to take several pictures in the store with the FLASH OFF. Exactly on the preview look. (I suppose you buy a camera, an LCD viewer,.) Now look for a darker surface (I like about the camera lean counter and try to take a picture of the wordbehind the counter, it is fairly dimly lit, as a rule) and take a photo without a flash, and while moving the camera. Are they blurry? If so, you need a steady hand and slowly or immovable property, if you try to take a picture in the house.

- Focus on a function, far away in the store, zoom, where the camera go, and a few pictures to shoot. This is another big test for the camera's ability to make indoor shots. If you do not enlarge to the other side the electronics store and take a decent, sharp picture, you probably will not be able to have in your home.

- Snap a quick overview of an unsuspecting customer to walk through. Are they taken a sharp and short, or just blurry?

- Go to a real camera shop. This is the best place for your sales staff who know how to really see the cameras, their differences and may help you compare similar models.

- Buy out who has the best price. It is remarkable that the retail prices for a given> Digital cameras can vary greatly from shop to shop.
