You Need to Shoot in RAW

The images you see on the web don’t come out of the camera the way you see them online. They’ve all been post-processed (some very heavily), and to make sure you have the best quality files to work with (especially important if you’re going to be tweaking your images in post-processing a lot), you definitely want to be shooting in RAW mode on your camera. Not only do RAW images capture a wider tonal range, they are much more forgiving and do less damage to your image when you need to make a lot of adjustments (and you are going to make a lot of adjustments).
