There are different ways to remove or reduce noise, and there are also ways of removing watermarks from images. But Nvidia has recently introduced a deep learning-based approach which has learned to fix photos by looking only at corrupted photos.

Two of the biggest complaints about small cameras like action and 360° cameras are their audio and fairly bland colours. The audio is often just the nature of built-in microphones, but the colours is often a function of maximising dynamic range in the source file.
To avoid us having to run our footage through yet another 3rd party app to fix them, Insta360 has developed True Audio and Color Plus features for their mobile apps and desktop editing software for the Insta360 ONE X (currently on sale for Black Friday) and the Insta360 GO to specifically address these issues.
Sometimes, when we’re out with our cameras, the light is a little lower than we’d like and we need to ramp up our ISO to compensate. But raising the ISO introduces noise. Potentially a whole lot of noise. And while you can never really get the image to look as good as it would have if you’d been able to shoot it at a low ISO, there are things you can do.
In this video, Unmesh Dinda from PiXimperfect shows us how to use the noise reduction tools in Lightroom to help reduce the impact of noise. This technique also applies to using Adobe Camera Raw. He then goes into Photoshop to illustrate how we can further bring back some of that lost detail.
DxO has announced DxO PureRAW, their new software to… Well, I suppose “pre-process” is the best term to describe it. It pre-processes your raw files before you load them into Lightroom, Adobe Camera Raw, Capture One or whatever raw software you happen to use. Its goal is to help improve your starting point with increased sharpness and reduced noise.
DxO PureRAW is not a plugin. It’s a standalone application through which you run your raw files before your usual editing workflow. It claims to remove noise, chromatic aberration, vignetting, distortion and to improve sharpness and clarity using DxO’s DeepPRIME AI tech after which it exports out a set of new DNG raw files for editing.
Topaz has recently launched its newest version of DeNoise AI, and I have tested the software on a night image. Does this latest iteration of Topaz’ noise reduction program live up to the hype? According to Topaz, DeNoise AI has received several updates and improvements.
When you run the program you can choose between two modes: manual and auto. Auto comes with only one slider (Chroma Noise). In manual mode, you can also adjust the level of sharpening and noise reduction applied. In addition, you can also decide how the program displays the changes in real-time. I have only used the split-screen option when testing the software. The real-time preview isn’t very accurate. The processed image looks quite different from what the preview suggests.
There’s plenty of great applications and plugins out there that will help you reduce noise in your images. Some are standalone apps while others are plugins. But there’s a lot you can do straight from within Adobe Camera Raw (ACR) and Lightroom without all that.
This video from Blake Rudis at F64 Academy talks us through the noise reduction features in ACR. As it uses the same raw engine as Lightroom, the same settings and techniques work the same way there, too. So, if you haven’t really dived into it before, or you’re relying on 3rd party apps, here’s how it all works.
When it comes to noise in photos, we are pretty accustomed to using DeNoising tools. When it comes to video, there are similar options that apply that same logic to footage, rather than to a single frame.
The folks over at Film Riot took two of the more popular options, Neat Video and Denoiser II (both at about $100) for a test drive and compare the results. Ryan talks about a third plugin called Dark Energy which he says surpasses them both, but sadly, it fell of the comparison for costing $100 more.
So, I’ve had this idea bouncing around in my head for a bit, and figured it might help me to get off my ass and actually try it out if I described my thought process.
I’ve been wanting to get some ND filters to experiment with daytime long exposures for a while now. The problem is that I’m lazy. So when I say “for a while now”, I really mean that it’s been like 3 years.
I had previously written about using median stacks to remove noise from an image, as an easy way to remove non-static objects from a scene, and to create interesting artwork. It’s those last two things that got me thinking…[Read More…]
Although some historians are not happy about upscaling and colorizing old footage, there are still many people, including me, who enjoy watching videos like that. NASS has recently published one from the 1930s, showing the vibrant streets of Los Angeles in the 1930s. Upscaled and colorized, it gives a new life to the footage and it’s a real treat for everyone who likes this kind of video work.
