The big thing about digital memory is written on it, it can be read many times with quality loss. A removable memory card or "flash card" can also expand the amount of information that can be saved and displayed, and you can import the card into photolab for processing. The availability of high resolution printers that accept flash cards allows you to print your photos at home without using a computer.

You are just beginning with a digital camera, or you are considering purchasing a new camera, and you replace what you hear about digital photos. Do you need a computer? Can you develop an image on behalf of any process and how can you do it Desktop application without paying all photos as a shop? It answers these questions and ideas on what your options are as long as you save, get, and display your digital photos go
A photograph taken with an optical film camera exposes the photosensitive film to the light projected onto the image by the lens on the surface of the film, a shutter open film at a rate of seconds stores the negative color impression of your image I will. Later it is developed in the dark room (or "positive" native personality photos of compact machines that do the same work these days.) Once you have set up, you can copy a fixed negative, and true Get a color photo of. The principle of digital photography is not much different. The microprocessor controlled photosensitive microtip wafer digitizes that image into an array of small colored dots called pixels, so that the photosensitive is sensitive to the light projected to the surface by the lens for only a second. This information is saved as a numerical sequence and recorded in the "memory" of the camera. This is an important part. Cameras usually have a small amount of "on-board" memory that is sufficient to store somewhere between 15 and 100 pictures. The amount of space a particular photo occupies in memory depends on many factors, but very simply, more detailed digital photos are likely to be used to generate images, high resolution digital photos He takes the digital space of memory.
The great thing about digital memory is that cameras from hundreds of thousands, thousands, or even millions of times without having to wear and wear, have a relatively small amount of memory on the board Because you have a removable memory card called "flash card", you can store a large amount of data while your camera may store 15 or 20 high resolution photos of it Flash Depending on the digital capacity of the card and the quality of the photo Flash card is a thin wafer between about 1/32 "and 1/8 of thick inch, and is usually not much larger than an inch square There are several different formats of these commonly used cards, which account for the majority of common image storage devices, including Secure Digit al, CompactFlash (1 and 2), Memory Stick, MultiMediaCard, xD Picture Card, SmartMedia, all of which are usually abbreviated as the first capital, of which SD and CF are the most It is common.
You have heard that all computers talked about in the 1s and 0s before, this is true. The standard unit for measuring digital data is "byte". In this exercise, 1 byte is always equivalent to 8 bits, 1 or 0. Therefore, sequences of 1 and 0 are 1 byte. This is a very small amount of data. On computers, bytes are enough information to store a single property, such as a period at the end of a sentence. To make things even easier, we have kilobytes kB (1024 bytes), megabytes MB (1024 kB), and gigabyte GB (1024 MB, or 10243 - which is 1,073,741,824 bytes).
To give your idea of scale, your medium or low resolution photos with your camera, perhaps somewhere around 500 kilobytes commonly available flash card size is 64 MB, 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, 5 GB, 6 GB, and some 8 GB flash cards have recently released more than 3000 very high resolution photo 8 GB flash card, and inch square! Small cards, the 512 MB flash card is much more cost effective, being between the new $ 10 and $ 20. The 8 GB one is close to the $ 250 + mark and represents the vertex of a miniaturized consumer grade data storage. And for the last trivial point of reference, the computer will be on these days an attractive optional for storing your pictures on your computer
Do not worry, if all things did not make much sense to you in the first reading. This is a subject which is more complicated to enter deeper and people devote their lives to their research. Beauty means that you do not have to fully understand it in order to use it effectively. For a handful of dollars, you can store hundreds of images. Flash cards can be reused almost indefinitely. Ultimately, they fail, because they eventually get deleted and used from scratches and cracks from friction and they are very sensitive to static electricity. For this reason, it is a good idea for you, or a friend with a computer, your photo on a more resilient medium such as data CD or DVD
This brings us to the next point: Do you need a computer? The short answer is no, it helps. Fortunately, the market developed an entire product range for people who want to remove computers entirely from equations confirming the demands that were for such a choice. On these days, you also want to make a particularly nice picture that you are developing at the pharmacy, that you have a plug-in, or an on-board card reader straight to your camera Print professionally, Photos are well prepared by developers and sorting is perfect. Everything you need to do is on the flash card or camera picture. What computers offer is a convenient way to edit collections and sort them. You can still display your photos on the camera itself, most cameras, so that you can see your photo like a slideshow
Never before had we had the ability to store such information so easily. There is a huge range of options for saving your pictures and you can store hundreds or thousands of pictures most Digital: listening is 16GB Microdrive. ....
Optical or digital zoom? The choice is clear
Many of us do not know the difference between optical zoom and digital zoom. In order to achieve the best picture quality, it is important to use the proper zoom function, so we will try to explain the difference. For optics vs. digital zoom to become confused, if there are manufacturers, this ad is the camera zone.

<strong> What is zoom? </ strong>
One of the stumbling things you need to focus on with Aki's pictures is a picture frame. For example, when taking a portrait photograph, when you want to make the object's face fill the photo frame, when you take a group photo,
In the frame of one photo towards Australia the function of the zooming function of the object physically approached or used. When using the zoom function, the camera (when mechanically applying the optical zoon or applying the digital zoom electronically) moves the area to the complete image frame
There are two types of zoom optics and digital (the only zoom option on older film cameras was optical). We will try to explain the difference between the two.
<strong> How does optical zoon work? </ strong>
Optical zoom works physically by moving the lens of the camera and changing the focal length. This is the full photo frame of the object size with only the focal length due to the change.
Sometimes you can satisfactorily shoot at the zoom position, press the shutter button only on the picture.
<strong> How does digital zoom work? </ strong>
Actually use digital zoom Embedded software recommends part of the definition of the camera in the photograph. Once you select the rest of the software crop photos, you will enlarge the selected area to fit the complete photo frame.
The process of expanding the zoom area is also called extrapolation. The camera software needs to calculate the new value of the cropped pixel to become a full frame picture. The disadvantage of this digital process is that the quality of the enlarged photograph is lower than the original picture.
