Unfortunately (or fortunately) in the software Apple Aperture 3.0 are no normal tools with which to successfully deal with noise from existing photographs. However, this problem can be solved with external editors such as Adobe Photoshop or by using the so-called plug-ins. In fact, one of these plug-ins I would now like to talk.
NeatImage - this is very simple and yet very effective and powerful tool with which you can quickly remove excess noise from your photos. In this case, I would further like to note that this program can be supplied in several variants (eg as a separate application as a plug-in for Adobe Photoshop or Adobe Photoshop Lightroom).
And so, what still stands NeatImage compared to other means to combat noise. Actually the basis of this application is very interesting image processing algorithms, which in turn provides a better quality of picture output. In fact, the work of the algorithm is based on the unique characteristics of your camera, which are recorded in the corresponding profile. Many of you may know or suspect that every camera, lens, and the matrix is unique. Sometimes these components photographic, may be quite serious differences from one another even within the same range the specific manufacturer. This means that "noise image" in images obtained using physical two different cameras, will be a unique character, which may differ significantly from each other depending on the specific shooting conditions (eg, exposure (shutter speed and aperture), the value of ISO, lens, etc., etc.). However NeatImage allows you to create a unique profile that will best meet the existing noise maps specific to your equipment. Thus, the algorithm NeatImage allows you to compare the "noise drawing "with the" noise "in your photos are typical for your equipment. The obvious advantage of this algorithm is that the qualitative characteristics of the image and its details have maximum values in comparison with other algorithms, which are used extensively when you remove "noise".
as an example for comparison of algorithms for removing "noise" from images I processed one of his photos using Adobe Photoshop Camera RAW, and then use Apple Aperture 3.0 and NeatImage Plugin. In both cases, I used the default settings of RAW converters, without any further color correction or sharpening. At first glance, the result is not much different from each other, but if you look closely, the image obtained by NeatImage cleaner, detailed (especially in fine detail) and better (sharp). Additionally, I would like to mention that I used a standard profile for camera Canon EOS 5D Mark II, which was downloaded from the developer's site NeatImage. I also assume that the results obtained using the profile containing information characteristic of my photographic equipment will be different and probably different for the better.
installation process is fairly trivial NeatImage and does not require by any serious brain activity. However, the site developers, there are several different versions of the applications that have a certain set of functionality and limitations. Become more familiar with the functionality of the different versions can be NeatImage here . Below is a достаточно простой способ обработки изображения с помощью данного плагина.
Фактически после того, как мы произвели необходимую коррекцию изображения. You can proceed to the immediate removal of "noise". To do this we need to go to the menu «Photos», then in the menu «Edit with Plug-in» and select «Neat Image ...».
After that you need to run in a separate window NeatImage, where you can process your image and properly control the process. При этом как я уже говорил ранее, обработка изображения может осуществляться на основе профайлов Вашей фотокамеры.
Для этого Вам предварительно will need to go to the site developer and NeatImage download the appropriate profile for your camera. In my case Canon EOS 5D Mark II. In addition, if you have not found profile for your camera, you should not be upset on this occasion, as a corresponding profile is not difficult. More details This process is described in this link.
Next, we need to load the appropriate profile for our image. To do this, click button «Load Profile» and select the location profile. Since in my case, the image was obtained using a camera Canon EOS 5D Mark II at values equal to ISO 3200, I realize select the appropriate profile.
Then, press the button «Noise Filter Settings» and check the results. In this case, if I do not like the end result, I can always use automatic algorithms, or modify the appropriate settings application.
As you can see, the processing image with NeatImage fairly simple, and does not require any major effort. Separately, it should be noted that this application also supports batch processing of images.
