Tips & Tricks

  • ✓Start with small adjustments and fine-tune gradually rather than large jumps.
  • ✓Increase contrast to make a flat, dull photo pop and bring out shadow and highlight detail.
  • ✓Use the brightness slider to fix underexposed or overexposed photos.
  • ✓If a result isn't quite right, re-upload the original and try again with different values.
