For most people the process of taking a picture is based on introducing a roll of film inside a camera, shoot until you run out and take it to a lab, where after a few hours gives us the impressions by which we must pay we like it or not. To this we must add that if the roll is placed in the wrong way no pictures

Digital photography now allows us to see a photo after taking it, delete it, store it on our computer, print or distribute over the Internet. Although this process is not so simple, there are some aspects to be taken into account before purchasing the right equipment for your needs.

When in any camera store digital camera is like, probably your first question is: ¨ how much? We suggest that prior to this questioning, thinking: "So that wants a digital camera? It should be borne in mind that you will use to digital images is crucial to know what kind of camera should choose. For example, if you just want to share photos of their families via email, a camera for pictures of low economic resolution is ideal, because light will create files that do not saturate the network.

If you play professional photography, a very simple camera may disappoint because at the time of printing, the photos will not be very great or good quality, said Fernando Castillo Gonzalez, director of Kodak's digital sales of Latin America.

Computer guides you through the purchase of digital equipment you need as needed.

¨ What is the proper resolution? Resolution is the number of dots (called pixels) with your image to be formed and it is very important because it defines the quality of photos and even get the price of the camera, said Fernando Castillo González, director of sales for Kodak's digital Latin America.

A very basic equipment you can shoot 640 x 480 pixels (ie the photos will consist of 640 dots horizontal and 480 vertical). This is a resolution that looks good on the computer monitor, but it is not suitable for printing because they have very small images on paper.

Meanwhile, with a 2.1 megapixel camera, the same photo will consist of 1,600 x 1,200 dots, bringing quality to create a bigger picture and more details at the time of printing.

The picture of the cover will find the printing done in accordance with the type of camera resolution.

But if you want to have photographs of the same size as it is commonly delivered in a laboratory requires a team of more than two megapixels.

Do you meet the requirements of the PC? It is important to consider that some cameras were designed for PC and Macintosh user if perhaps not usable. Also most cameras require a port to connect like USB (Universal Serial Bus), which usually is integrated into the teams about three years now, or FireWire, you can download dozens of pictures of her camera in seconds. Make sure there is a connection on the PC, otherwise it would have to buy an adapter.

If you want to download and save high-resolution photos, it is essential to have enough hard disk space (at least two gigabytes).

On the other hand, most digital cameras have software that must be installed on the PC to connect the camera and download images. This software also helps you improve your photos, should check that the software is compatible with the operating system of your machine.

Print directly If you have PC, there are some teams that let you print without intermediate used. For this purpose requires that the digital camera memory card count, which is fed directly into a slot on the printer. The main manufacturers of these devices are Epson, Canon, HP.

Although there are different memory cards on the market (for example, Compact Flash Card, MultiMediaCard, MemoryStick) requires that the model is the same for the camera and printer. There are small liquid crystal displays that are added to the printer, through which you see the image before printing ... CONTINUE ..

The memory capacity of digital cameras photos are stored on memory cards whose capacity ranges from 8 to 120 MB (some low-level cameras have internal memory with no expansion capacity cards).

The number of pictures that can be placed on a card depends on the capacity and size of the image that the camera can offer. The bulk of the equipment allows the user to select high or low quality in his images, it should be noted that an excellent definition requires more storage space.

For example, we say that an image taken with a camera of 640 x 480, which is the lowest rank, in JPG format (which is the most common) \ "weight \" 300 KB in high quality definition and 90 KB in half .

Based on the foregoing, in a 16 MB card can store approximately 60 high quality photos or 90 medium resolution.

In contrast, a photo from a camera capable of 2.1 megapixels in HD weighs 1.7 MB and 420 KB in medium resolution.

Thus, in one 16 MB card can only store five excellent quality pictures or 19 high quality.

Functions Finally, all cameras have additional features like the ability to record a video with audio, to enhance photos in the dark, working as a PC or video cameras to shoot moving objects.

As for zoom, digital cameras have a lens option, which is important because it relates to the role of the lens. The digital version expands the images with computer processes.
