Image Formats of Digital Cameras: RAW and JPEG

Most digital camers support two main image formats: JPEG and RAW. JPEG is the default format of all amateur cameras, when RAW is mostly the format of professionals.

JPEG files are often trade-off between compression and image quality. That means that you can adjust image compression thus affecting image size. The bad thing is that the compression rate goes along with the quality of an image. The higher compression is the lower quality an image has (though the size of the compressed image also goes down). Fortunately many cameras let us to set the compression rate of JPEG images. Large images are suitable for printing while small images are good for the web.

RAW files are different. They are not processed in the camera and preserve every bit of captured image. Sure it leads to larger size. The advantage is that you may process the RAW images later on your pc with a photo editing software. All the setting can be undone (except aperture, ISO, shutter speed, and focus). Note that when you save your RAW files as JPEG all the settings are permanently applied to the images and you lose your advantage.

This is the way every photographer thinks:

  • I don't care about image size but I want to have the best quality possible - I choose RAW or uncompressed JPEG.
  • I want the best quality and full control over image - I use RAW.
  • I want to fit as many images as possible to my memory card and I don't need high quality - I use JPEG high compression.

Anyway your choice is not final. You can later convert RAW to JPEG or resize JPEG to make its size smaller and suitable for the web.
