Reducing Noise

You can reduce noise that arises in JPEG and TIFF images that have been shot at night or with a high ISO speed.

1Select the [NR/Lens/ALO] tab sheet from the tool palette in the edit window or edit image window.

2Adjust an image.

Drag the sliders right

OYou can set a noise reduction level from within a range of 0 to 20. The larger the setting, the larger the noise reduction effect.

3Click the [Apply] button.

¿Noise reduction is applied to the image and the image is redisplayed.

4Display the image in the [100% view] or [200% view].

¿You can check the noise reduction effect.

OIn the [50% view] or [Fit to window] display, it may be difficult to check the noise reduction effect.

To check the noise reduction effect, enlarge the image and display it

Because noise reduction effect is difficult to see in the [50% view] and [Fit to window] displays, use [100% view] or [200% view] to check the noise reduction.

O If [Luminance noise reduction] has been set, resolution may be reduced along with reduction of noise.

OIf [Chrominance noise reduction] has been set, color bleeding may occur along with reduction of noise.

OYou can set the batch processing settings for noise reduction beforehand, using [Default noise reduction settings] in the [Tool palette] tab sheet in Preferences (p.75). This is particularly useful for applying noise reduction to all the images in a folder at once, such as batch noise reduction for images with high ISO speeds. However, where images have a recipe attached, the noise level recorded in the recipe is applied.
