Camera File Formats

Modern cameras like a DSLR have two usable file formats mainly RAW and JPEG. Choosing your file format depends on how you want the camera to process the photos.

Choosing RAW format in Canon DSLR

Every time you capture an image, your camera processes the image to create a photo. The image created by this process creates a JPEG file, which is the photo itself. A RAW file records the image but does not create a photo yet. You can think of RAW files as a digital negative file, which requires processing before it can be used. This also enables users to edit the image before creating a JPEG file or photo.

The Pros and Cons

        Photo editing friendly; mistakes made during the shoot can be corrected. This includes exposure, white balance and other stuff. Thus, providing users with much more flexibility.
        Since no compression is made, no image data is lost.

        RAW format creates large files; it lessens the amount of photos that can be captured when using JPEG.
        Requires programs that can support the file format. Usually the bundled software is used to process RAW images.
        Requires high powered computers to process and create JPEG files.
        Processing can be time consuming.

        File size is smaller than RAW; this maximizes the space of the memory card.
        Editing and viewing is easy, any photo editor can handle JPEG.
        Sharing photos online, to friends, e-mails and other social networks is faster due to small file size.
        JPEG is a standard file format; it is supported on every type of computer.
        JPEG compresses the photo; during this process some details of the photo is lost.
        Harder to edit compared to RAW, because details are easily lost when intense photo editing is done.
        Lesser control over the outcome of the photo.
