PLEASE SHOULD I ALLWAYS SHOOT IN RAW...? WHAT ARE THE BENEFITS? RAWvsJPEG... WHEN I SHOULD USE JPEG?.... IS THAT DIFFERENT?.... WONDER TO HEAR YOUR EXPERIOENCE AND EXPERTISE...!!! THANKS IN ADVANCE.
Yes, it is different and worth doing. To create a JPEG, the camera does some manipulation on the image and then compresses it in order to reduce the size. This is why it is called a "lossy" format. RAW is an ummanipulated and uncompressed format so you have total freedom to make corrections and manipulate the image based on the full data. You do need a RAW converter (Lightroom, Aperture, and plenty of other cheaper or free versions) to make the image viewable - but it's worth it. I use Lightroom to change the exposure, correct the colour temperature, boost saturaton, reduce noise and sharpen the images before saving to TIFF format (a lossless format). Hope this helps, regards.

Raw is definitely better but need more work, raw is normally 16 or 32 bit which is better than jpeg's 8 bit. When you edit in jpeg you lose quality and get what they call banding (if you have to editi in jpeg, change the 8 bit to 16 bit first before editing - may help to reduce the banding). Dynamic range of raw is greater than jpeg hence slightly overexpose/underexpose images may be saved.
If you need a photograph in a hurry - (say you saw something newsworthy and want to send it up to your local paper) or if you just want a photograph to e-mail to someone then you may as well use JPG to save yourself the additional processing time. Otherwise always use RAW. That is why some cameras have a 'RAW + JPG' button that tells your camera to record the image in both formats - just for those odd moments when you may need a JPG image.
