Noise Reduction Software |
Noise is a very much like the film grain that one finds in film
photographs. It is the grainy texture that comes out in digital pictures
as a result of shooting a picture using a high ISO. In today’s
digitally-driven world of photography, the presence of noise is
inevitable.
Therefore, every photographer needs to deal with noise in his or her
lifetime. There are a lot of techniques that one can do in order to take
out the noise in a photograph. However, doing this over and over might
result in an unproductive work flow for you as a photographer.
Fortunately, there is a solution to this particular problem. Enter Neat
Image.
Neat Image is a "noise reduction software" which essentially does
what it so proudly professes to do: it completely takes out the noise in
a digital image. Because of this software, digital photographers may
now get rid of the noise in their photographs without compromising
picture quality.
In the past, if one removes noise and grain from the picture using
different techniques or primitive filters, the detail within the picture
is lost. This detail is responsible for defining and filling in shadows
as well as outlining the edges of an image’s subject.
So while the noise is essentially removed in previous noise reduction
filters, the picture will tend to look like it was washed out and
sometimes may even take on a "plastic" overall feel when the image is
done. This is because along with the noise, significant information is
lost within the noise reduction process.
The noise reducing algorithm of Neat Image
is sophisticated enough to precisely calculate the noise that is on an
image. After it does this calculation, it works at taking away the noise
without discarding any valuable information that the editor might need.
This is because Neat Image recognizes the extremely random nature of
noise and how it can sample an area of the picture that contains the
noise. This essentially gives the user a preview of a before and after
shot of the picture with and without noise. The user can also
effectively adjust how much noise is taken and from what channels should
the noise be reduced.
Through this type of technique, the amount of information that needs
to be kept is maintained and the information that the user needs to
discard is effectively removed from the image.
The beauty of Neat Image is that the software is also able to profile
different cameras as well as camera settings so that the photographer
will be able to simply load them if they recognize that a particular
image may be applicable for a certain type of softness. An example of
this is when you have photographs that were taken at ISO 800 during
nighttime.
Since you have a photograph with a high noise value, you could
essentially apply a noise reduction profile which can deal with the
amount of noise that can be found in ISO 800 shots taken at night.
