           STEP 3 : Editing the exposure.

           •  A rule of thumb says that if in doubt, you should underexpose your photo slightly as valuable image details are
              lost in overexposed photos.
              •  EXPOSURE

              •  BRIGHTNESS
              •  HIGHLIGHTS
              •  DEPTHS OR SHADOWS
           •  In addition to correcting exposure, you can also reduce image noise in photos. This occurs when you have
              worked with a high ISO value or a long exposure time.



























           STEP 4: Changing the contrast.
              •  Contrast describes the ratio of black and white tones in the picture .
              •   A low contrast blurs the contours, while a high contrast strongly emphasises the contours and makes the
                 image look exaggerated.























           STEP 5: Adjusting the white balance.
              •  White balance (or temperature) controls the colour temperature of the image. When it comes to white
                 balance its more about personal preference or what your picture should represent.

              •   A warm white balance makes your picture look inviting and summery.
              •  A cool white balance, on the other hand creates a more distant and wintery image.
