Understanding RAW & JPEG

On your camera there is an option which you can choose the file format of the captured images, RAW (Canon CR2 - Canon RAW version 2 and Nikon NEF - Nikon Electornic Format), JPEG or even both. Here's a video from Mark Wallace for AdoramaTV, an in-depth explanation of RAW and JPEG files.

RAW vs. JPEG by Mark Wallace

In most cases, RAW offers flexibility to the shooters, in terms of exposure (2 stops overexposed and 2 stops underexposed), white balance, sharpening, etc. With affordable electronic storage space (memory card & hard drive) available in the market, file size will never be a problem. But will be bit expensive in terms of software to be used for editing. While JPEG offers portability which allows you to shoot thousand of  images without carrying dozens of memory card. RAW and JPEG have their advantages and disadvantages. Which is better? There is no definite answer to that question. But for beginners I would suggest to begin with JPEG, why? 

1. To focus more attention in shooting than sitting in the front of computer.

2. To understand what camera setting is required for a certain scenario.

3. To develop consistency/ instinct in shooting.

And just a piece of advice, if you're already shooting RAW there's no excuse to say that you'll make corrections (exposure and white balance) in the editing software when you can make them right away on the camera.
