If you are overwhelmed by the thought of it, then I must say that the purchase of a digital camera you probably will not be disappointed, becauseit is a good thing, necessary and very comfortable.Moreover, this technique has now become readily available for when there were only a digital camera, buy them was almost impossible because of the fabulous price.

purpose of buying

And what do you need a camera?At first glance a trivial matter, but in fact from the responses to it depends on many things.Actually, the choice of the camera and is based on what goals will be carried out of the acquired photographic equipment.
I will assume that 90% of cases, and even more, the camera is purchased for the "household" needs.What does this mean?And this means that the machine will take pictures so mostly at home, at work, all kinds of parties and events.And then the ordinary "Soap" will be enough for the eyes.If you want to take a photo more than an amateur, often travel in tours, it is possible you already need a mor
e serious machine.
What's the difference between "soap box" and more serious machine?
«Soap" knowingly took its name from household goods - it is the shape and size resembles the eponymous subject.But for all its comfort, it has a modest capabilities."Great," the device has the classic layout, it larger, tend to be heavier, but more functional.

But first things first.
course, a decisive role, in most cases, plays a budget for the purchase, to put it simply - the available amount of money on hand.This reduces the choice.Moreover, the smaller budget, the easier it is to select, becausenumber of models subject to the necessary amount is reduced.
Next start from the purpose for which you need a camera.If, as mentioned above, only "household" survey, the "soap box" will be the same.This will save you a considerable amount of money will get quite adequate and compact device.The compactness of the property is very convenient.This camera is easy to carry, it fits everywhere and not much burden for transportation.
Of course, high quality, he does not shine, but in most cases its functions and quality is sufficient for everyday shooting.By the way, the choice of digital "Soap" MirSovetov advises not to give in to a marketing step and fall into euphoria on the number of megapixels.There may be any number!The number of mega pixels determines the resolution of the CCD (charge coupled device), ie,sensor camera (analog film).While crucial for the camera is still the lens.A demand that the lens "Soap" posh settings, at least, stupid.For there can, at best, three-lens objective with such a small diameter lenses ensure high quality.And the matrix itself, even with the same number of megapixels on "Soap" significantly inferior to the parameters of their "elder brothers."
If you do decide to close the photo, plan to travel frequently to rest in the tours, you do not interfere with the "big" machine.Its bulkiness, weight and high price offset high image quality and more features for shooting.
And how it does affect quality?If you print photos only format 10 * 15, you will not notice the difference.But when you print size 15 * 22 or more, the difference will be noticeable quite clearly.This deterioration of sharpness (definition) and the emergence of noise (artifact in the form of colored dots), and some "zamylennost" images in the pictures "soap box".
happens so that it is more convenient to have two digital cameras - and the "big" and "Soap".Then your options are almost limitless.I repeat: the compactness and mobility "Soap" is indispensable.

shopping trip

Well, you have decided on a "weight category" camera.What next?And then you can safely go to the store.The point here boils down to - to what shop?Photographic equipment sell all and sundry - and cellular kiosks, supermarkets and electronics (and not only), and specialty stores.It will be correct to bypass the set of points.Compare product range and prices.But preference is still necessary to give the last - the specialty stores.Why is that?Here, read!
As you know, the price still does not solve all problems, and if you find the same item for less, do not hurry to rejoice.There may be various options.Either store has a large turnover of goods and a proven track record, or try to deceive him, luring low prices.Cheating may be different.Whether it's one-day firms or goods, simply put, is defective or out of date.Either he imported on illegal circuit, etc.etc.And it may happen that the warranty on the goods in such unfortunate and rather conventional firms in which case (God forbid), you will not get anywhere.And if the firm will burst, then ...
And ignore the guarantee in the pursuit of low price for such a complex technique is not necessary.Repair at its own expense may result in a round sum.
So, for digital cameras only in reputable stores!What else plus specialty shops?The fact that there is much more choice and advise you, and there is much better than "universal" sellers supermarkets.And the prices are generally quite acceptable, ascompany is engaged in a narrow range of products.

How to choose a digital camera

On the shelves of the sea varieties of digital cameras from different manufacturers.But despite this, the range of possibilities is almost the same for all cameras of one "weight" category.So we can not say that "the soap dish» NIKON much better SAMSUNG'a.They are about the same level, and the choice of the brand rests on your taste.Especially since almost all available domestic (there are professional) "Soap" in China, ie,in China.But, if you decide to purchase a machine more serious, it is best to choose a known and trusted brand: NIKON (only makes cameras, which is good);CANON, OLYMPUS, SONY, Panasonic, etc.Some "big" machines, for example, SONY R-1 can still be found in Japan, which guarantees high quality.
And here is how to determine which one to take?To do this, let's move closer to the window and read the price tags.By the way, you will not hurt to take a small notebook and pencil - it will facilitate the comparison of different stores.
And what did they write?And about the same.It is not difficult to guess that the title is listed the name and the type (model) of the camera.It will be largely interesting.Did you record your favorite model, and then on the Internet, for example, see a detailed description and reviews.
Sometimes it happens, and so that is already below the price - for all sim.This is not good becauseIt reduces choice and talking about contempt for the company to the buyer.You're not going to ask seller about the price of vending models - it will take a lot of time.It is better to avoid buying in such cases.
But if all the same price tag contains a brief description, then it is usually possible to find the following information.


lens is used to produce a sharp image on the sensor.It contains name, type (model) as well as a range of focal lengths (if zoom-lens) or a particular value otherwise.It also indicates the range of values ​​for the zoom-aperture lenses, asdepending on the focal length varies aperture.
Lens
lens - is the most expensive part of the machine and the equally complex, so more detail MirSovetov elaborate on this device, see "Choosing a lens for the camera."

Matrix
designed to convert projected on her lens optical image into a digital signal.
There is sometimes referred to its type.A CCD () - a charge coupled device.Is obsolete type, where the reading signal is similar to a cathode ray tube (CRT) - sequentially from left to right and top to bottom.Sensitive elements are silicon photodiodes.Naturally, the options are far from ideal."Soap" is equipped with this type of matrix.
CMOS (CMOS silicon semiconductor metaloksidny) - an analogue memory of your computer where reading can take place from anywhere, you just specify the column number and line number.Each pixel is a sense amplifier.Parameters such matrices far exceed the above-mentioned type.They are equipped with "older" model.
Live-MOS - formed by MOS (metaloksidny semiconductor) has a smaller number of connections for a single pixel, and requires lower voltage power supply, reducing power consumption and heat generation.This configuration provides a more "live" image without inherent above matrix types overheating and increase the noise level.
Next comes the actual resolution MPix (megapixels), and sometimes write geometric size.Incidentally, the larger the geometrical dimensions with an equal number MPix, the better.Naturally, the increase in the number of megapixels the quality will increase (with the previously specified clause).
course, if the choice was unprofessional (or the most expensive of the household), "bar of soap", then you'll have to settle for CCD matrix.But there is big trouble, becauseits duties it would take quite regularly.And it may even be that you will not feel its shortcomings.If you have chosen the "big" machine, then give preference CMOS matrix.
With regards to the number of megapixels, it is quite tolerable images can be obtained by including more than 5.Otherwise, the survey will be of a technical nature, for it is not possible to print photos more than 10 * 15 (the quality will be very mediocre).


Viewfinder The viewfinder - a system of selecting the object (s) photography.And they, with all the complexity of technology, all four types: LCD (liquid crystal - LCD);electronic EVF (electronic view-finder), optical parallax and reflex viewfinder.The type of viewfinder does not directly affect the image quality, but, nevertheless, its value in the process of producing good images is sufficiently large.In modern cameras, almost all models have an LCD display, it can be in splendid isolation, or in combination with other types: LCD + EVF and LCD + optical.
So, at this time, almost all digital cameras are equipped with exactly LCD.This decision has both pluses and minuses.The display requires a backlight, without which it will work, but the user can not see anything.Therefore, use the backlight LEDs.If the backlight is too weak, the display "fades" when the ambient light conditions.In the more expensive devices display with a more powerful illumination and they allow you to see the picture on them in almost any ambient light (even in the sun).However, this causes their high power consumption.Of course, there is a possibility of serious apparatus adjust the backlight, which is very nice.As a rule, this is indicated as follows: "Display: Dark;Normal;Bright. "
Please note that there is a fixed (built-in) displays, and there are mobile.The latter allows to change their position, which is convenient when shooting at an angle or above (below) and to reduce the noise level (noise).
There is a standard range of sizes display diagonal: 1.5 "1.8";2.0 "2.5".It would seem that the larger the better.But this is only partly true.In fact, it is seen on a larger display better its resolution is generally higher but the power consumption is also higher.Although it displays less than 1.8 "should not be taken into account, as anything seen on such a display would be problematic. In addition, if you are a more advanced photographer, the use of such a display would be difficult.
For this purpose, suitable for bothtime viewfinder EVF. This is analogous to a conventional viewfinder "reflex" (more on that below), but there is not a pentaprism, no mirrors, but the meaning remains the same. This viewfinder is applied to the eyes a special window, eyepiece, which is only visible display.
This viewfinder eye is applied to a special window, eyepiece, which is only visible displayIt
devoid of "blinding", and it will be seen always. EVF Another advantage is that it has a display where more smaller size than the display on the rear side of the housing, and the increase is due to the viewfinder optical system provided with a correction system ofphotographer. The small size of the display leads to a significant reduction of energy consumption and noise.
But these two types of viewfinders have the same drawback - the inertia of the display. It is caused by it so that the information on the display can be updated instantly.Moreover, it must still be read from the matrix.
Optical viewfinders are not mentioned drawbacks, since no power at all.Parallax viewfinder - if you remember the camera "Change" or conventional film "Soap", here is a viewfinder and meaning.It is simple and reliable, but also has, however, disadvantages.Firstly, such a viewfinder "cuts" 20% of your field of vision (ie, the real picture will turn out 20% more).So something will come out of the field of view during shooting and will appear in the final print.Second, it does not assess the correct focus.
Well, now we come to what does it mean - "SLR"?It is a system implementing the viewfinder through a complex system consisting of eyepieces, pentaprism (penta prism), mirrors the drive and the lens itself.The image created by the lens is transmitted through these elements in the eyepiece viewfinder.In order not to hurt the mirror (it obscures the matrix or film) at the time of his exposure (shutter) raises the drive that generates a characteristic sound of the shutter.If you read carefully, you will have noticed there is a word "matrix".It seems to be a misprint left.No, there tsifroviki- "reflex", but they are more expensive, becausecomplicated mechanism.
Pluses: lack of energy viewfinder and noise;the absence of inertia (for professionals is a crucial moment);the actual display (without distortion).
But there are also disadvantages: the complexity of the design and its appreciation;decrease in reliability;the appearance of the reaction of the camera mirror cotton (body twitches slightly in the vertical direction).
should be noted that one of the significant advantages of SLR cameras is the ability to change the optics, but this issue MirSovetov also paid a special attention is devoted to the lenses.

Scenes
If you use a film camera, then I think you know them.
Shooting Modes Digital Camera
Typically, everywhere there is "Auto" mode - fully automatic shooting and modes "Sport", "Portrait", "Landscape", etc.The purpose of these regimes is clear, while there, such as the shooting mode Aperture priority.As such use will be discussed in a future article.

Memory Cards
This built-in or detachable (removable) devices for recording and storing footage.As you probably guessed, this is the digital "film".Most digital cameras has the most simple memory - built.It usually has a size of 32 MB, which significantly limits your ability becausewith high quality, the number of recorded pictures is extremely small, and the speed of its work is far from perfect.Therefore it is better to select the device with the ability to use removable media.Then you can, keeping in stock N-number memory cards, shoot plenty.This is extremely important on long journeys.Only buy additional cards, note that they are different standards.Ask the seller what kind of approach to this unit (in an expensive camera supports multiple cards of different standards in digital "Soap" - usually one).
Memory Cards
most common: SD (some of the currently available);CardFlash;Memory Stick Duo.But how to choose a memory card - a topic for another article.

Power
Needless to say that a digital camera, in contrast to the grandfather of "Zenith", requires a power supply.For this purpose, various power sources.
Most inexpensive digital camera is powered by two batteries "AA" in common - finger.Not so expensive it seems at first glance.The fact that "eats" a lot of digital camera, much more than a similar film camera.And take care of buying new batteries you have to quite often.In more serious
devices used batteries.Currently used only Li-ion (Li-ion) cells.Without going into details I would say that this type of battery allows recharging from any point sincethere is no "memory effect" that forces wait for complete discharge.However, it is necessary to charge the batteries before the end.What next?
