Introduction To The Formats For Saving Photographs

When a picture is taken, the image is stored on the memory card. The rescue of the photographs on the memory card is through the process of encoding, or the camera follows a particular pattern (a code, of course) for a particular save format. This scheme is primarily act to reduce the final size of the image, or to collapse it. In most compact cameras,

pictures are encoded in JPEG format as default. Many cameras, however (and particularly SLRs), can be set to encrypt the photos in different ways, each with its pros and cons.

Generally, the compact saved in Jpeg while, going up in price and quality, plus TIFF and RAW (RAW vs. JPEG article I introduced two of the formats listed).
Pros and Cons of the formats for saving photographs

JPEG is the most famous and widely used format for saving images. Used by all digital cameras, JPEG is a lossy format, which means sacrificing the image quality to ensure a small file size.

The advantages of JPEG:

Small file size: you can fit more images on a memory card and transfer images to your computer faster.
Saving photos faster The gusts cameras are faster.
JPEG files can be viewed on any computer without third-party software.

The disadvantages of JPEG:

When capturing an image in JPEG format, the sound is softened and the image is generally sharp. The camera generally reduces the image depth from 12 to 8 bits which translates into a loss of detail and quality.


Recommended use for JPEG

JPEG is the best format to use photo in general, such as parties and social events where you need to take pictures quickly.
JPEG generally do not require any conversion pass to the computer, or the image is immediately usable anywhere.


RAW files are not compressed and are not processed. RAW files must first be processed using third-party software (usually provided by the manufacturer of the camera before they can be printed or changed. The most renowned software (such as Photoshop, Lightroom or Aperture) are equipped with a converter ( as Camera RAW) whose aim is to decode the RAW image, different from camera to camera (I refer you to Article linked above).

The benefits of using RAW

The main advantage is that the image processing is performed on the computer. This means that if you’re about to take a picture and you are not sure that white balance and exposure settings are optimal, you can (a few stops!) Develop the computer image correcting precisely the shooting parameters.
