False myths on Resolution
Errors not surprise me that even today continue reading (and hearing) a lot of people is the resolution of a picture . For starters, there is much confusion about what we mean by this term. Well, simply refers to the total number of pixels that has the photo. For example, a 12 Mega Pixels camera generates a file of, say, 4,000 pixels x 3,000 pixels = 12,000,000 pixels. The resolution of that photo (or more precisely, the file) is 12 million pixels.
Resolution
But often you’ll hear someone who has asked you a picture (even an advertising agency!) Say that “I better with 72 points per inch . ” This information is useless. What we have to say is how many pixels you want to take the photo. For example: 1,500 pixels wide or 800 pixels high. This data perfectly defines the resolution of the file that you send. As an example, these pictures have a resolution of 900 x 600 pixels, a size suitable for the Internet.
And the dots per inch?
The question then is, what resolution do I need? Depends on what it is going to use the photographs : for viewing on the monitor or to print ? And here come into play dots per inch (also called dpi or ppi).
Classification of camera – by type
This time we will discuss the different styles of cameras that can be found in markets. When you’re buying a product of this style is a very wide range. The decision will impact very large depending on the quality of the selected component, and the price that leaves the team. The cameras are digital, the other and were in time and no longer sold new, are divided into two groups. These are compact and SLR. But there is an intermediate category called ultrazoom. Beyond that it is staying in the shadows of the world of technology we will mention them.
First, there are compact cameras. These are a very small and can be manipulated from one place to another very simple. They are usually those used by families who are very passionate about the quality of the picture, but just want to take snapshots of the fondest memories of their lives. Operation is very simple and not so expensive. Anyone who does not have a very high purchasing power will have a camera of this class.
The optical zoom These cameras usually have between 3 to 5x. This makes it clear that are right for photos of landscapes, or any image that does not require very long focal. If you are not skilled and you want to start in this area, please choose a compact camera as you can take good pictures without spending a fortune.
