Best software for noise reduction – Amateur Photographer
Nov 08, · Presumably you have found the Noise Reduction tool? There are some techniques that one might apply that might include the use of other tools or the way that things are set up when shooting but I’m not aware of anything more specifically called an “Advanced Noise tool” other than the advanced nature of the Noise Reduction tool.

Use Layers to Apply Noise Reduction to the Shadows in Capture One — Thomas Fitzgerald Photography
Imagine yourself under a starry night sky. It’s time to open up the aperture, lengthen the exposure, and bump up the ISO. You will introduce noise, but do you really care? In fact, I would love to learn which current software reduces noise the best myself. There are many tricks and tools available to enhance the quality of our images, about as many as there are genres in photography. I’m choosing to compare those tools on a nightscape image, because its typical usage scenario is almost always the same.
In which other genre do you max out the ISO as well as the shutter speed for almost every shot? Anyway, raw converters and Photoshop plugins will help to reduce noise, but what we really want is to increase the exposure of the stars in these nightscapes without increasing the noise. We want to increase the signal-to-noise ratio.
If you can follow along, this next part may appeal to you. The rule of thumb is the rule, which states that if you divide by your focal length on a full-frame camera, the maximum shutter speed in seconds pops out at the other end of the equation.
While this may be the case when your composition includes either celestial pole, it is definitely not the case when you capture the galactic core of the Milky Way. Even a shutter speed of 20 seconds with a 14mm lens on a full-frame body is really pushing it in terms of preventing star trails.
The rule is a better rule of thumb, but for the sake of the argument, think more along the lines of a rule if the Milky Way is the subject for your full-frame.
Think of a star that at the beginning of the exposure is in one place. As it progresses along the night sky, its image is projected upon the camera sensor. A photodiode, a piece of a pixel on a camera sensor, translates the brightness of that star into an electric charge. The electric charge recorded over the exposure time multiplied by the ISO-setting is a measure for how bright that star actually is.
Now, consider that at the end of the exposure, our planet has rotated and the sky seemingly shifted one pixel. The camera used to capture an image to test the capabilities of noise reduction software was the Nikon D , with a native ISO range of , Above that range, the signal will be amplified once it’s been recorded by the sensor.
At any lower setting than , that signal is attenuated. The maximum setting on the D will overexpose the city lights on the horizon light pollution , so we avoided maxing out the camera.
That keeps the light-polluted horizon well within the histogram and certainly works wonders for noise reduction purposes. We will work with Adobe Lightroom as a hub to find, compare, and eventually process the image. What we are doing in this step, is called pre-processing: creating a single file which you can work with in your favorite image editor. This comparison is intended for reducing noise before you do anything else to it in order to retain faint stars and nebulae.
As for the tested raw converters, I have only turned on the noise and sharpening modules in those, effectively exporting the same result as Lightroom should. What can we do with three images, shot in quick succession at exactly the same camera settings? Of course we can try to auto-align them in Photoshop, but that will not get us very far.
The sky shifts with each exposure, while the foreground is static. A dedicated free program will aid us in the alignment. I ask that you trust me when I say that using multiple exposures that are offset slightly from each other result in the best possible noise reduction method without sacrificing small details.
And the more images you have, the better your result will be. The true workings of stacking software are very complicated and are not within the scope of this comparison. Stacking the exposures in Photoshop through a median mode is achieved by importing each registered exposure into a separate layer, then selecting all three layers and going to to Layer, Smart Objects, Convert to Smart Object. The median method above works pretty well when you have a large number of exposures.
Another method to stack your images in Photoshop is by averaging them. Averaging the three exposures works by putting each registered one in a separate layer as well. While the stars are perfectly aligned with the help of DeepSkyStacker before, the foreground is all jumbled up. First, I can hardly sit still for a couple of seconds and yes, this is a glorified selfie. Second, DeepSkyStacker detects stars and aligns the images based on their position.
The foreground then gets distorted due to the rotation of the Earth. To compensate, I typically shoot one extra exposure just for the foreground at a lower ISO setting and longer exposure length. Do be aware that increasing the shutter speed will also increase the temperature of the sensor, and that will introduce thermal noise in your foreground.
As you can see, producing a clean, noiseless nightscape involves advanced planning, shooting, and processing, but that’s not why you’re here. Averaging the three images does produce a marginally smoother image, as seen above. Here is stacking versus raw with added contrast:. So, the above comparison shows our best stacking method with three images. Mind you, three images is not a very good stack, but it sure does help with suppressing noise. We will move on to comparing each application with that average stack, so we can see how well they reduce noise without sacrificing detail.
These suites perform a host of features. Noise reduction is one of them. The idea is that raw files contain more data, and when you get rid of noise during this step, it is more accurate. Let’s see if there’s any truth to that. PRIME noise reduction is one of them, and it is supposed to yield amazing results. I’ve used these settings, which gave me the best results for this image:.
Average stack vs. PRIME noise reduction on raw. It’s nice and smooth, but optical aberrations at the edges of bright stars become more apparent, which is easy to correct with the built-in lens correction feature at the press of a button.
However, faint stars are getting drowned out by the higher contrast that its raw conversion algorithm produces. In Lightroom, I’ve applied these settings, which yielded the best results for this image:. The careful color noise reduction comes at a cost, but the Masking setting is great. The latter works by not applying any sharpening on smooth areas, thus only sharpening fine detail. There’s a lot of color noise going on, but the preservation of colour in the stars is quite good, just like the contrast in the nebulae.
Capture One noise reduction. Capture One’s sharpening is quite similar to Lightroom’s, with the Threshold slider preventing smooth areas from becoming overly sharpened. The amount of noise reduced is very similar to the average stack, but there’s much more random color in large swaths, while there’s almost no color at all in the stars. I personally do like the pattern of this noise, since it resembles film grain and doesn’t look quite as digital, but that’s a matter of taste.
A plugin is something that works in or around your image editing workflow. You can apply a specific filter in a standalone program and come back to the image editor with your photo hopefully looking better than before.
I’ve racked up the most popular noise reducers that work together with Photoshop. Photoshop has its own noise reduction filter. So, why go through the trouble and price of a dedicated noise reduction program? I’ve found that these settings with this filter give the best results for this image:.
Photoshop’s Reduce Noise Filter. The amount of noise reduction and color almost look identical to the stack, but that’s where the similarities end.
Some of the larger, faint stars are pulled from the sky. Large stars are reduced in size and the structure of the nebulae becomes much harder to see, and there’s a distinct swirly thing going on with a good amount of introduced local contrast. Recently, Google announced that the Nik Collection is now free to download. There’s absolutely no reason not to use and discover the power of both Color Efex Pro and Silver Efex Pro, but what about the collection’s noise reduction plugin? I’ve left the measurement on auto and increased the reduction of Contrast Noise, while I toned down Color Noise for best results.
That’s interesting. Faint stars in the darker areas are erased, while stars in the brighter nebula are mostly left alone. The pattern looks slightly swirly, but more natural than Photoshop’s attempt. There’s also a slight increase in saturation on some of the stars, while others have been desaturated.
Finally, we see less structure in the nebulae, and medium brightness stars are reduced in size. But not bad for a free plugin! As with most of these suites, you’ll get a host of applications along with Noise Ninja, one of the most talked about noise reduction algorithms in recent times.
Does the Noise Ninja 4 Turbo engine live up to the hype as we apply these settings to our night sky? The noise pattern looks identical to me.
That’s a good thing. And the reduction does a good job at smoothing out the background. However, the stars in that background are smoothed until there are none left, while the overall image looks to me like it’s pockmarked rather than star-speckled.
The nebulae do look more cloudy and contrasty than some of the contenders, but not by much. But just look at the amount of settings. I tweaked these for the better part of two hours to get the best result I could squeeze out from DeNoise.
It’s buttery smooth, but with a lot of digital-looking artifacts. I like the fact that this algorithm works by analyzing things locally.
