Digital Camera


Digital Camera

Today, the digital camera is not a luxury, which was long ago, and the same familiar and indispensable thing, such as a mobile phone, and almost every one of us makes a purchase. Well, if you know exactly which model you need, but what about those who have never interested in photographic equipment? The variety of companies and models that are currently on the market, can easily find out.
To understand what camera you need, think about what and where you are going to shoot. Do you plan to photograph family events, meetings with friends, etc. Or you, for example, traveling, or just want to create beautiful quality work, is higher than at the amateur level? If the first – then you is fine reliable, inexpensive, compact digital camera. If the second – you should look for a more serious camera (SLR with interchangeable lenses, the so-called “poluzerkalku”).

Digital Camera Manufacturers

Choosing a digital camera, take a look at manufacturing firms. Conventionally, they can be divided into three categories.Nikon D50 Digital Camera
1. This is the most well-known companies, they specialize exclusively in the production of digital cameras, and therefore the quality of the equipment is not in doubt: Nikon, Canon, Olympus, Pentax.
2. Firms known but concentrates only on photographic technique, or not very well known, but no less quality: Kodak, Casio, Fujifilm, Sony, LG, Samsung, Minolta, Panasonic.
3. proper rest, either virtually unknown brands or those which do not associate with photographic equipment: Kyocera, Praktica, Rekam, Premier, Skina, HP, Mustek, Hobby, etc.
The first two categories of quality cameras are practically no different, except that in the first case, you will have to pay a certain amount for the manufacturer’s name. As for the third category, the point is not that bad, these cameras or not, and that predict their behavior no one can, which means that they are unreliable.
Which company would you choose, the parameters that need to be addressed when choosing all the same.
Matrix
First – it is a matrix camera. From it and from optics to the same extent will depend on the quality image.
You should not chase the number of megapixels, because in fact it only affects the size of the output image, which can be printed without any loss of quality, and not on the quality of the image. How many megapixels you need? It depends on the tasks you set for yourself. If you want to print photos, you should know that the “standard” print quality – it prints at 300 dpi (300 dpi). Accordingly, in order to print the photo size 10×15 cm, you must have the original picture size 1200h1800 points, that is, the matrix is 2.2 megapixels, and print pictures 13×18 cm – 1600h220 and matrix 3.5 (this is a rough calculation algorithm) .
It is not necessary that an 8-megapixel camera, you get a high-quality images, with 6-MP. There are cameras and 10-12 megapixels, but pay attention to the fact that sometimes as highest resolution indicates the size of the image produced by the “digital stretching.” That is, the actual number of megapixels overpaid.
Optics

Digital Camera Lenses
How to recognize poor quality optics? Pictures taken by such optics, the contours of objects with different illumination is not clear, and surrounded by purple and yellow stripes on the sides. You can only check the quality by making shots. To test the difference between the images of illuminated objects in the frame should be as large as possible (some dark object against a light background, or at least the roof of the house against a bright sky). Captured images to watch either on a computer monitor or on the camera screen as large as possible.
The main characteristics of the lens are considered – aperture and zoom.
Aperture ratio
Luminosity – This maximum aperture. The larger the lens speed, the better and more expensive camera. At the same lighting conditions, a lens with a large aperture allows shooting at faster shutter speeds.
Usually, the lens can be seen about these mysterious figures: 5.8-34.8mm 1:2.8-4.8. The first pair of numbers indicates the focal length (the distance from the front of the lens to the matrix). Second – this is the value of the lens aperture. In this case, the numbers tell us the following: in the position of 34.8mm (at maximum zoom) lens aperture is 4.8. The smaller the aperture value, the better.
Zoom
This is a handy feature, which are equipped with virtually all digital cameras, allows you to enlarge. It is a mistake to assume that “the more zoom – the better.” Zoom – is a value which the ratio of maximum and minimum focal length. And that is the focal length depends on how many “go down in the frame.”
The more zoom camera, the harder it is design, and the manufacturer has to find a compromise between cost and quality. Therefore ultrazoom (6-12x) usually give worse image than zumami moderate (up to 3x).
ISO
ISO – a unit matrix sensitivity to light that strikes it.
The higher the sensitivity, the lower the light can be removed. But the quality of the picture there may be degraded (Photos may “noise”). The lower the ISO, the better photos in the end turn out. On the cheap machines noise impacts already ISO of 400.
Food
The camera can be “native” battery, that is, the company that manufactured the device. On the one hand it is a plus – as its capacity is much higher than that of conventional batteries. On the other hand, sometimes it can be a big drawback – if, for example, while walking, he sits down, then you have to look where you could recharge it. This is no problem if the unit is powered by a “finger” size batteries AA – you can find them in any local store. But the battery power is sufficient for significantly less time than the battery. Another way – AA-batteries-batteries, which is one of the best options.
For the life of the power supply also affects the camera LCD screen (the higher it is, the more energy consumption) as well as flash and zoom.

Do not forget, though, that you purchase a thing to be, if not always, it is often with you, so in addition to all the technical characteristics, it is important to make you feel nice and comfortable to hold the camera in your hands. Check – convenient if you click on the button, use the menu to switch modes. Pay attention to the weight of the camera, do not be hard for him to carry.
