For those who are not computer savvy, buying a digital camera can force the issue of learning a few things about computers if they want to download, save or print their pictures at home. New knowledge about file formats is one example. Understanding a bit about how the images are recorded on a digital camera and then stored on a computer is critical, but fairly easy, even for beginners.
Digital cameras capture images through a grid of pixels. Since the dataInformation about the network of pixels that must be communicated to a computer for downloading, storing and printing, the format used by the digital camera to store the data must be understood by the computer as well, regardless of the type of software used by the computer. Thus, there are standardized file formats, allowing this communication and data transfer.
There are a variety of file formats, but there are few who are the most commonly used with images. To know which of these fileFormats to use when recording and storing images from a digital camera is vital in ensuring good image quality.
• JPG: The JPG file format is the most commonly used for photos. Most digital cameras are set to automatically save images in JPG. The JPEG format compresses files to save disk space, but in the process eliminates some of the data, which degrades image quality to a small part.
Users can change the degree of compression / picture quality, fit for their digital camera.However, factors such as degree of compression reduces and increases image quality is the number of images of the camera or memory card able to store notes. It is simply a trade-off between image quality and storage capacity.
The choice of the JPG file format is often a good choice for color and grayscale images set whether the images on the Internet, for display on the screen or production of regular expressions.
Users need to understand the digital cameras that recorded images on the camera canbe to store computer in the same or a different format. However, originally an image in JPEG is taken never been a better quality than those in which it was originally recorded. So if a user can record an image with high compression on their digital camera, they do not cause compression or save them as uncompressed TIFF file on your computer to get a better picture quality expected.
Every time a JPEG file is opened, edited, saved and lost data and is thus the image qualitylost as well. Thus, users should make every attempt to originals stored on your computer, so that the image does not always become worse with repeated treatment.
• TIF: The TIF format can store images without compression and therefore without loss of image quality. This format can be both Macintosh and Windows-based computers. The choice as to whether the TIF file format to use is useful when the size increased, since there is a greater need for high image quality in theseSituations.
Many digital cameras offer users the ability to shoot images in TIF format.
While this allows for excellent image quality drastically reduced the number of images to be stored and therefore far less frequently used by the average photographer. However, if a user wants to produce large prints, setting their digital camera to capture images in TIF format and save it on your computer in the same way would be recommended.
• be GIF: The GIF file formatThe most commonly used for graphics and animation on the web. It has a limited color palette and is therefore not generally a preferred choice for color photos, although it works well with black and white images. GIF format images are also slightly preferred over the Web as a background can be made transparent, and because of the manner in which they can be displayed images load / display help faster.
Some of the less commonly used, save images in BMP, which also produces very large,uncompressed images as wallpaper, pic, which uses the file format for Macintosh computers, Adobe Acrobat PDF, EPS, FlashPix and PNG, which will be used primarily for graphics, and PSP, the photo-shop format. However, correspond to the average person to record and store images from their digital camera in JPG, TIF, GIF, or their needs when they understand the advantages and disadvantages of each and how to adjust accordingly.
