Rather than just cranking up the overall noise reduction, an alternative technique is to just reduce the noise in the shadows. In Capture One. Agree. Before trying to reduce noise, best to tame Lightroom’s sharpening. Otherwise, Lightroom sharpens your noisy background and you have to. In Capture One Pro 7 every camera has its own noise profile, customized by our image quality experts, and color noise and luminance noise will be removed.
 
 

Best software for noise reduction – Amateur Photographer – Registering and Stacking

 

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.

There is a lot of different answers to that question. My editing process consists mainly of adjusting color, contrast and details. For me this means I get a highly efficient workflow that allows me to do a lot of work in a short amount of time — not only on assignments where time is of the essence, but also everyday in the office.

I find Capture One Pro 9, combined with the highest image quality, to be the strongest asset to me as a photographer. This is further helped by the High Dynamic Range Shadow and Highlight Tool, as well as the Clarity Tool, which allows me to control contrast very well.

The Local Adjustment Tool also got an upgrade in Capture One Pro 9, which is very useful for both detailed work and broader adjustments using, for example, the Gradient Mask tool. With all these great new improvements to Capture One Pro 9, I was excited to be invited to test the Beta version well before the release. While testing the beta version of Capture One Pro 9, I did a photo essay of a dirt bike rider named Ronni, here in my home city of Copenhagen. With this goal in mind, I set out to sort and edit the photos.

Below you can see a step-by-step run through of my workflow:. The original RAW, directly from the camera. The first thing I need to secure, when I start to edit my pictures, is a good base. Therefore I start by establishing the starting point for dynamic range and colors using the Levels tool. Correcting Levels for desired details and colors in the whole dynamic range in the Levels tool. Here we can edit each color channel separately for greater effect, and even use the Color Editor tool for even more possibilities.

Now that the image is monochrome, we need to add contrast to achieve the desired feel of the image. For this series I wanted to have a dark and moody effect, so I added a lot of contrast, balancing on the dark tones, but without getting all black.

All of this greatly achieved the dark moody look I was after. To guide the viewer towards the centre of the frame, where the action is, I here added some vignette to the frame, using the Vignetting tool. To do this I used the Clarity tool to bring a bit more details forward, and the Noise Reduction tool for a clean file, which I can then add beautiful Film Grain to.

It might seem a bit odd to first use Noise Reduction and then add back noise; but in my mind there is a clear difference between the digital noise, and the beautiful film noise from Capture One Pro 9. The Film Grain also helps to further strengthen the dark and moody look I was going for.

For the final touch-up I use the Local Adjustment tool,for areas that needed special attention. I used it to get a darker sky, to add a bit more Clarity to areas that needed it, and then finally to darken a few highlighted areas, all without ruining other areas. Capture One Pro 9 gives me even more creative possibilities, in a fast and effective workflow, and still deliveries second-to-none image quality.

I am a Danish, Copenhagen based photographer specialized in dramatic on location photos that stand out from the crowd. This is achieved by using the environment surrounding the object to add drama and story to the photos, while using creative techniques and dramatic lighting for further strength. I strive to add value for my clients by going above and beyond. Why do we edit pictures? Share this:.

 
 

Noise reduction in capture one pro 9 free.The Ultimate Comparison of Nine Noise Reduction Methods for Night Photography

 
 

In the full book , you will find 60 chapters over pages of similar quality with more than screenshots. Capture One Pro can remove both the luminance and color noise from your images with the Noise Reduction tool. Note that some color noise reduction is applied automatically to raw files because there almost always is some base color noise present in a raw file even at low ISO values.

All cameras have their own customized noise reduction that is optimized for each ISO value by the team behind Capture One Pro. This means that the hard work is already done, and Capture One Pro will provide you with a tailored noise reduction that can be fine-tuned further if need be. There is one important thing to be aware of when you work with the Noise Reduction tool. As you will note, both the Luminance and Color noise reduction sliders are by default set to 50 , but this does not mean that a heavy dose of noise reduction is applied, or that all images receive the same amount of noise reduction.

You should instead think of the sliders as a way to control the balance between preserving detail and reducing noise. When at 50 , it merely means that this is what Phase One regards as the best balance. You can increase the amount of noise reduction by setting the Luminance and Color sliders higher than 50 or decrease the amount by setting them lower than The Details slider works in conjunction with the Luminance noise reduction amount and lets you increase micro-detail at the expense of more noise when you move it above 50 , while you can smooth out the noise at the cost of detail with a value below The Noise Reduction tool also has a very nice feature called Single Pixel.

With this slider, you can remove those nasty, hot pixels that often show up on long exposures, especially during the night. The Focus tool can be a nice help to quickly check different parts of the image. It is impossible to recommend certain values to use with the Luminance , Detail and Color sliders because this depends on the noise level in the image, the quality of the light and your preference.

In most cases, you will probably find that the default Color noise reduction works great. The only thing you need to pay attention to is that the colors can be blurred too much and lose definition if you set a high amount, like The hardest part about removing noise is to strike the right balance between applying a nice luminance noise reduction and still retain the details.

Instead of just increasing the Luminance slider to the max to get rid of the grain, you might want to reduce Detail the same amount as you increase the Luminance so that the values would be Luminance 70 and Detail 30 as an example.

If you still struggle with getting rid of the noise, there is a couple of additional tricks you can use. You can increase the Threshold value in the Sharpening tool to make sure fewer details get sharpening applied, and you can use a negative value with the Structure slider in the Clarity slider. Finally, if you have trouble with a lot of noise on an even surface like the sky, the Skin Tone tab in the Color Editor tool has a marvelously Uniformity feature that evens out the tones and thus mitigates the noise.

This trick will be covered later in this chapter. Both the Structure and Skin Tone trick are probably best applied on a layer with the Layers tool because you can then limit their effect with a mask.

You should be aware that Capture One Pro might automatically add some simulated grain with the Film Grain tool to help get a more natural noise look at higher ISO values. If you find that this adds more grain that you like, remember to set the Impact slider back to 0 zero in the Film Grain tool.
