Decide The Image File Format to Suide Your Needs

Each time that you press the shutter release, you capture an image with the image sensor. The image is then written to a file in a user-selected format with or without applying your chosen camera settings. Most digital cameras other than basic point-and- shoots offer two formats: JPEG and RAW.

Most digital photographers use the JPEG format. It offers a nice balance between image file size and image quality, plus it is universally recognized by software that can use photos such as word processors or page design programs. The JPEG format is a compression format; it uses a mathematical algorithm to smartly reduce the file size while losing minimal image quality. At high quality settings (which you should generally use), the loss is negligible, yet you can capture more images on a memory card. RAW image files are proprietary files that have minimal processing applied to them by the camera, plus they hold more tonal information than JPEG files. A RAW file can be processed with much more flexibility and adjustment range than is possible with JPEG.

The RAW format is the best image format to use if you want to get the best possible pictures from your digital camera. Camera settings, such as white balance, contrast, saturation levels, sharpening, and other settings, are not applied to a RAW image file. After you shoot, you have control over these settings when processing them with a RAW image converter. Many photo enthusiasts shoot in RAW format most of the time, or choose RAW + JPEG if the camera offers that setting.

RAW format  images  are proprietary, data-rich files that you must  convert before  you can view and  edit them.

You can shoot more JPEG images in a row compared to RAW before the camera’s memory buffer is filled, making the camera stop in order to catch up. On the other hand, RAW allows instant changes to white balance after the shoot with no effect on the image quality.
