Noise reduction

0:03 Noise reduction · see the starting image
The RAW is ISO 2000. Compare smooth colour and fine printed detail.

0:08 Inspect noise at 100%
At Fit, small noise changes can be difficult to see.

0:14 Choose Everything
This cleans luminance and colour noise together.

0:20 Increase noise reduction
Watch the flat colours become smoother; too much can erase paper texture.

0:28 Preserve more detail
Keep detail trades some smoothness for retained fine structure.

0:35 Try Colour only
This suppresses coloured noise while retaining more luminance texture.

0:41 Compare the colour-noise strength
Use an obvious amount to see the difference in shadow colour.

0:48 Reset to the photo’s starting settings
