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.
