effectively removes image noise while preserving essential details
and the photographic quality of the image. It offers sharpening,
saturation and grain features for enhancing the image after
denoising. You can also apply denoising with extreme settings
to create painting-like effects.
is available as a Photoshop-compatible plugin for Windows
and MacOS X. A Windows Standalone/Lightroom version
is under development. The NoiseControl plugin works
in dozens of graphics applications, including Photoshop, Photoshop
Elements, Paint Shop Pro, Photo-Paint, PhotoImpact and IrfanView.
It supports batch processing, smart filtering and processes
grayscale and RGB images with 8-bit and 16-bit/channel.
Effective Noise Processing
people want to remove image noise, because of its ugly or obtrusive
appearance. Another problem arises when you try to sharpen a
noisy image, which yields amplified noise rather than increased
sharpness. NoiseControl effectively deals with both problems:
It removes image noise
and other artifacts while keeping image edges and details intact
and at the same time applies sophisticated sharpening
without amplifying noise.
NoiseControl distinguishes details
from noise by performing thousands of clever calculations per
pixel. Thus it is able to achieve a superior detail/noise ratio
by keeping essential details while filtering noise. For best
results it internally operates with 16-bit and 32-bit precision,
even when processing 8-bit images.
NoiseControl offers two methods
for automatically choosing effective denoising parameters: The
Auto Sample feature finds and evaluates a
noise sample, a uniform image area without any details, whereas
the Auto Preset feature chooses an existing preset according
to the embedded EXIF data, mainly the camera model and ISO value,
of the photo.
are also various possibilities to manually fine-tune the denoising
settings. You can manually select a noise sample in the preview
by drawing a sample area, visually compare split views with
different settings and select one of them or you can manually
adjust the denoising controls. The ability to view luminance
and color channels separately is an additional aid for manual
The best results are usually
achieved if you selectively adjust the denoising for various
image areas. For that purpose NoiseControl allows you to alter
the denoising parameters in shadows, midtones, highlights and
nine color areas of the image. These selective adjustments can
be performed with the help of sliders or by clicking on the
appropriate image area with the eyedropper tool and dragging
left or right.
also offer various features known from our other PhotoWiz plugins.
a simple mode for novices as well as an advanced mode for pro
users. There are three
preview tab sheets for quickly comparing and adjusting three
versions of the image at the same time. A
Navigator tab sheet lets you quickly scroll the preview image
and the preview zoom can be set between 6% and 3200%.
On the other hand NoiseControl
contains several innovative features. It
does not only support multi-core CPUs, but also detects your
CPU's L2/L3 cache and adjusts its memory usage accordingly,
which results in faster rendering. For faster preview
updates you can use the preview limit tool to restrict the effect
to a smaller preview region.
Why NoiseControl is Different
other noise reduction tools mainly
rely on automatic calibration, which does not produce the best
results for all images, and offer only limited manual adjustments.
NoiseControl features several fine-tuning methods including
automatic, semiautomatic, manual and visual options. Thus it
achieves superior denoising results, especially when fighting
very strong noise. Most denoising tools add artifacts along
with sharpening whereas NoiseControl's sharpening feature makes
details crisp again without side-effects.
Some tools need several seconds
to update the preview, because they need to render the whole
image, or only update a small part of the preview. NoiseControl
updates the preview very quickly and still displays the effect
fairly accurately at zoom levels other than 100%. NoiseControl
offers an easy to use UI and does not confuse the user with
cryptic options. It does not require a complex sequence of denoising
steps but displays the result instantly.
Some denoising software manufacturers
advocate a plastic look and falsely encourage users to shoot
with higher ISO values. We do not want people to exchange one
evil with another. We believe that it is better to turn obtrusive
noise into very fine grain, thus preserving a higher photographic
quality. This philosophy is reflected by the moderate default
values and the "Control" part of the NoiseControl
name. Nevertheless NoiseControl also allows you to produce a
soft look if that is what you want.
