The right format for storing digital photos by Panasonic Lumix DMC FZ28K 10MP

Old cameras captured images on film. Digital cameras to store photographs, however, in the form of digital files. There are many file types each with each own format. Here is a statement of a few common digital image file formats.
If you have photos with the Panasonic Lumix DMC FZ28K 10MP each photo is saved as a digital file on the digital camera memory and is very likely later on your computer. Like any other computer file, digital photo files can have different formats. Each computer file consists of a long series of bits and bytes. A file format is a description of the importance of bits and bytes or in other words, a file format is explains how to read and interpret. If you want you can take a file and file format for writing text. If you write a sentence you give is basically a series of characters. They are meaningless unless you know that they are in a format called English, and that certain combinations of characters have certain meanings.
There are a few common formats for storing digital photos each with its advantages and disadvantages. In general, digital cameras, as the Panasonic Lumix DMC FZ28K 10MP, you can choose which format you want to use. The first big difference between the types of format, where the compression method used, if at all. But first, can quickly verify what compression is and what she needed. A digital photo is a collection of pixels. Each pixel represents a tiny proportion of the total digital photo and has a color and intensity attribute. In general pixels in true color than three bytes triplet. Each byte corresponds to an intensity of a prime color. Mixed together they are an exact color and intensity of the display that pixel.
The size of a digital photo file depends on the resolution in which it was taken is also known as the number of megapixels. The number of mega-pixel camera as you grow more advanced. A common 8-megapixel camera produces eight million pixels for each digital photo you take. That is a lot of pixels with 3 bytes per pixel digital photo storage each will consume 8000000 pixels by 3 bytes = 24000000 bytes well known than 24 megabytes. This is a very large file. It will lead, with less space on your camera memory card for storing photos, it is difficult to process, slow to send via e-mail, slow to upload to a website and so on.
Fortunately, there are efficient way to store digital photos, consume much less space. In every photograph that you have a certain amount of redundancy and inefficiency. Compress a digital photograph is a method that removes redundancy and information that are not important or not felt by the viewer. In our previous example, a 24-megabyte digital photo file could easily be compressed to consume only 3 megabytes with little noticeable deterioration in quality.
The compression method described above is also known as lossy compression, because some information, although hardly noticeable was lost. There are other compression method are known as lossless and the creation of a compressed file can be uncompressed on exactly the original file. However, they are less efficient and may not be such a high compression ratios to convert a 24-megabyte file into a 3 megabyte file.
Most cameras, you can choose between two photo formats, compressed or RAW. Raw format is simply the uncompressed digital version of the photo and it consumes a lot of space. Professional photographers using RAW format, since it would improve processing quality of the photo later. For all other photographers a compressed JPEG file is a better choice. Digital cameras, as the Panasonic Lumix DMC FZ28K 10MP You can also select the compression rate. The higher the ratio the smaller the file but also the more degraded the quality of the compressed image.
