ESSENTIAL SKILLS CORRECT UNDERWATER COLOURS
Learn how to fix blue colour casts with simple skills in Camera raw or lightroom
When shooting underwater the white balance and colours can be difficult to perfect in-camera. By shooting Raw, we have the option to adjust the white balance after, with the exact same results as if we’d done so before. To correct the blue casts that often affect underwater photos, use Camera Raw (or Lightroom’s) white balance eyedropper tool and click on a point that should be neutral, like a white piece of the clothing. Then go on to tweak the White Balance Temperature and Tint sliders until the colours look right. If the sky is showing through the water, correcting the colours might skew those above the water. If it does, try painting with the Adjustment Brush tool loaded with negative temperature and tint.
