Noiseless Pro from Macphun lets you reduce the amount of visible noise in photos.

Noise is ever present in digital images, it’s a fundamental property of any electronic system, and the discreet nature of light adds even more to it at low light levels.

Camera manufacturers go to great lengths to reduce the amount of noise that their equipment shows, but there are limits. The smaller the sensor on your camera, the more noise will show up, especially at low light levels.

The question becomes one of how much noise is acceptable in any particular photo.

Noiseless Pro is an Apple Mac application that can process your images and improve how they look. Keith has been trying the Pro version of the software as a plugin for Photoshop.

V1.1 update (Aug 2015)

  • Batch Processing, users can process a number of images at once, resizing, renaming and saving files in popular image formats (JPG, TIFF, PNG)
  • Users will have the option to select from automatic noise reduction, use a built-in preset, or even create their own custom preset. Custom batching presets can also be saved so a combination of options chosen previously can be used again.
  • The Light, Moderate and Medium presets have been improved to give even better results with portraits and photos where the noise is minimal
  • 14% speed increase.
  • The new version will be available for $49.99 as a limited time offer, or within the Creative Kit for $99.99 only

When noise is a problem

Two factors contribute to the amount of noise visible in a photo.

It’s largely about the amount of light that a sensor chip has to work with.

Smaller camera sensors have smaller pixels making up their sensors, which work with less light going in to them.

Higher ISO (sensitivity) settings are making use of even less light.

If you add these two together, then smaller sensors (phones, compact cameras) tend to produce noisier images.

There are lots of other factors (enough to keep many forum threads running) but without going into much more detail, you can assume that any picture has noise, and that it becomes more noticeable with smaller/cheaper cameras in lower light.

The upshot of this is that phone camera images at night tend to look noisy, and even much ‘better’ cameras may show too much noise at high ISO to make a photo worth using.

The image to the right is a highly magnified (200%) section of a photo taken with my Canon 100D (SL1) at its highest 25600 ISO setting.

It’s a photo of a coloured test target (see below) where I’m looking at the JPEG image straight out of the camera.

Noiseless Pro – What do you get?

I’m looking at the Pro version of the software, which works as a standalone App and as a plugin for other software

The software will install as a trial version. This needs activating once you have purchased a copy.

The software installs as a stand-alone application. To use it as a plugin for other image editing programs, you’ll need to install the plugin options. The software finds any relevant software and will install as needed.

Using Noiseless Pro

The software works very simply, in this instance I’ve opened the plugin whilst looking at a night time photo taken with my 100D at 6400 ISO.

You can see that I’ve selected a before/after split view, and the whole image is visible.

To really see the effects of noise reduction, you do need to zoom in though.

The basic mode just offers a range of preset levels of noise reduction.

The amount of noise reduction applied affects different parts of the image in different ways

Move your mouse over the image below to see two different settings.

As you can see, noise reduction comes at a cost, in terms of fine detail.

You can push the reduction even further.

Why would you do this?

Well, the shot above shows a highly magnified view – if you’re only making a small version of an image for the web, then higher noise reduction might make for a cleaner looking image – that said I couldn’t find an image of mine that looked good at ‘Extreme’…

Note that ‘Amount’ slider though. You don’t have to have all settings turned up to full.

If you switch to the ‘Adjust’ view, then you can see that the simple noise presets hide a lot of individual settings.

These are what live behind the ‘Medium’ setting.

Just turning down the overall strength (opacity) of the adjustment may be all you need

Move you mouse over the image to see the effect.

The individual sliders’ effects depend very much on the image. Sometimes a bit of residual noise in an area gives the impression of more detail. The various presets are good starting points, but a bit of experimentation may produce much better looking results.

Some sliders may not have much effect at all on your image, or cause big changes – see some effects below (mouse over image)

With a much higher ISO image (25600), the coarse noise is relatively easily reduced.

The loss of fine detail (real or imagined) is quite noticeable.

Note the small navigation window I’ve activated, to give some context for just how small a part of the whole image this is.

All the tests so far have been on JPEG images from my 100D – not a bad camera at all, but one that I’d rarely consider using at 25600 ISO.

I hardly ever carry a mobile phone with me (yes, really) so don’t have any sample images to test, but there is a demo of the software available, so it’s easy enough to test.

Looking at JPEG images means you are also relying on noise reduction carried out by the camera. If I was taking photos at high ISO though, I’d be taking them in RAW format and then applying noise reduction during processing.

RAW files

The Noiseless Pro App will open RAW files, and also allow you to export converted files to other applications for processing.

There are basic controls for RAW processing, and the settings for noise handling.

processing a RAW file

At 200% you can get an idea of how the processing affects this particular image – how well it works with other cameras and images is something you’ll just have to try.

I’ve used many different RAW converters over the years, and they all have good and bad points – this is one of those areas though that you will have to do some experimentation to see. Step by step ‘recipes’ for image processing workflow should only ever be thought of as a starting point

Any tests of RAW converters giving hard and fast conclusions are almost guaranteed to be wrong IMHO ;-)

The software is easy to use and effective, although to get optimal results you will need to experiment.

That, and have an idea of what ‘Optimal’ means to you in the context of any particular image and what you want to do with it.

If you use JPEG images a lot and regularly use a phone camera or compact, then Noiseless may well be just the tool you are looking for, particularly when used with some of the other Macphun image editing applications.

Coming from the commercial, architectural and landscape photography background I do, the software is unlikely to be as useful to me as Tonality and Intensify, since I just don’t tend to shoot any serious (paying) work at high ISO.

It’s one reason I never updated my Canon 1Ds Mk3 to a 1D X – differences at 100 or 200 ISO were negligible.

There are lots of additional resources on the Macphun web site. (more details are here:
