Sharpening and Softening Images
Adjusting the Quick sharp Picture Control setting is a quick way of making pictures sharper or softer.
Image definition can be further fine-tuned using Sharpening, Mid-range sharpening, or Clarity.
●● Step 1: Make Quick Edits Using “Quick Sharp”
●● Step 2: Fine-Tune “Sharpening”, “Mid-Range Sharpening”, and “Clarity”
Step 1: Make Quick Edits Using “Quick Sharp”
Adjustments to the Quick sharp Picture Control settings made by choosing a value between −2 (Softer in the i menu) and +2 (Sharper in the
i menu) are automatically matched by balanced adjustments to Sharpening, Mid-range sharpening, and Clarity. Select A to let the camera
automatically choose the optimal values for the scene.
For images that are softer overall, select a negative (softer) value. This can be used, for example, to
soften the complexions of portrait subjects.
Picture Control: Standard
Quick sharp: 0
Quick sharp: −2 (softer)
For images that are sharper overall, select a positive (sharper) value. This can be used for landscapes
and other situations in which greater overall definition may be required.
Picture Control: Standard
Quick sharp: 0
Quick sharp: +2 (sharper)
Landscapes
Positive values for Quick sharp are particularly effective when applied to distant landscapes shrouded
by mist or haze.

Step 2: Fine-Tune “Sharpening”, “Mid-Range Sharpening”, and “Clarity”
After using Quick sharp to obtain the desired overall look, you can finetune the results using Sharpening and its sisters. The examples below
show how to soften the complexions of portrait subjects while leaving
their eyes clearly visible. The recommended settings for images destined for printing vary with output size.

Choosing Picture Control Settings Based on Output Size
How an image appears when viewed from a given distance varies with the output size:
• When pictures are printed or displayed at a large size, small details will be visible. Most adjustments should
therefore be made using Sharpening, which effectively softens or sharpens fine elements.
• When pictures are printed or displayed at a small size, small details are not visible. Most adjustments
should therefore be made using Clarity, which has its greatest effect at the borders between the main
subject and the background.

“Sharpening”, “Mid-Range Sharpening”, and “Clarity”
Sharpening, Mid-range sharpening, and
Clarity each apply to different areas of
the image. In the picture shown here, for
example, Sharpening can be employed
in fine-tuning the appearance of eyelashes and other fine details, while Clarity is
best used to make the subject stand out
from the background. Mid-range sharpening is effective in adjusting the level of
detail visible in the middle range, such as
around the nose and mouth.

When images are printed, the visibility of each adjustment varies with the output size.
●● Sharpening: This parameter controls the sharpness of details and outlines and can be adjusted in the
range −3 to +9. Its effects are most visible when images are output at larger sizes, equivalent to A1
(approximately 0.5 m2/5.4 sq. ft).
Sharpening: −3
Sharpening: +9
sharpening: This parameter controls the sharpness of patterns and lines in the range between Sharpening and Clarity and can be set to values of from −5 to +5. Its effects are most visible when images are output at sizes equivalent to A3 (approximately 0.125 m2/1.3 sq. ft).
●● Mid-range
Mid-range sharpening: −5
Mid-range sharpening: +5
This parameter controls the sharpness of the borders between the main subject and the
background and can be adjusted in the range −5 to +5. Its effects are most visible when images
are output at smaller sizes equivalent to A4 (letter size) or a 5 × 7 print.
●● Clarity:
Clarity: −5
Clarity: +5
“Clarity”
Large changes to Clarity may result in apparent changes to overall contrast.
“NEF (RAW) Processing”
Sharpening and other settings for pictures shot in NEF (RAW) format can be adjusted after shooting us‑
ing Capture NX‑D or the NEF (RAW) processing option in camera’s retouch menu, whether or not they
have previously been altered on the camera.

Capture NX‑D
As of January 2019, the only cameras with Quick sharp and Mid-range sharpening are the Z 7 and
Z 6. Capture NX‑D versions 1.5.1 and later, however, offer these parameters with all NEF (RAW) images, regardless of the camera used to create them. The procedure varies depending on the camera
used for the original picture:
●● In the case of NEF (RAW) pictures taken with a Z 7 or Z 6, Quick sharp and Mid-range sharpening will
be available via the Picture Control tool in the edit palette.
●● In the case of NEF (RAW) pictures taken with a camera other than the Z 7 or Z 6 *, Quick sharp and Mid-
range sharpening will only be available if you click the Picture Control icon (q) in the edit palette
and select Camera compatible > Latest Picture Control from the Picture Control menu (w).

* Digital SLR and Nikon 1 cameras.
Capture NX‑D can be downloaded free-of-charge from the Nikon Download Center at the URL below:

Be sure to use version 1.5.1 or later. More information is available via online help.

Keeping Pictures Sharp at Small Apertures
Enabling Diffraction compensation in the photo shooting menu helps
reduce loss of definition caused by diffraction in pictures taken at small
apertures (high f/-numbers).
Diffraction Compensation
While the effects of diffraction may still be visible in landscapes and in other pictures taken with
aperture stopped all the way down, enabling Diffraction compensation lets you shoot at small apertures without worrying too much about loss of definition. It is generally recommended that you
shoot with Diffraction compensation enabled, although it can be purposely disabled for photos in
which the effects of diffraction are visible.
f/22, Diffraction compensation off
f/22, Diffraction compensation on
Diffraction compensation is available with Z mount lenses as well as with CPU-equipped F mount
lenses connected via an FTZ mount adapter (non-CPU lenses are not supported).
Capture NX‑D
The Diffraction compensation option in the Capture
NX‑D Camera and Lens Corrections tool can be used
to turn diffraction compensation on or off when NEF
(RAW) pictures taken with Z 7 or Z 6 cameras are displayed.
“Diffraction Compensation”
The Diffraction compensation option in Capture NX‑D
is available only with NEF (RAW) pictures taken using a
Z 7 or Z 6.
