DxO PhotoLab 4 comes with AI-powered high ISO noise reduction

Tips & Techniques

DxO’s PhotoLab has seen a lot of improvements over the years. Their latest iteration, PhotoLab 4 comes with some pretty impressive high ISO noise reduction along with a host of workflow speed and other features. These improvements allow you to customise the user interface and provide easier access to your more commonly used tools, as well as adding a few new ones.

The big advantage DxO has over most of the competition is that they’ve kind of become a standard for benchmarking cameras and the images they are capable of producing. This means their engineers have used pretty much every digital camera ever made and worked with the files they produce. It also means they have access to a database of millions of images. Images that they’ve been using to train their deep learning AI.

This leads us to the DxO DeepPRIME AI engine built into PhotoLab 4, which denoises your images during the raw file demosaicing process to maximise image quality in the final output and offer increased noise reduction while retaining as much of the original colour and detail as possible at higher ISOs and in low light environments.

And it works on really old cameras with pretty terrible high ISO performance, too! Like this Nikon D300S at ISO2500 (I shot a D300S for years, no way I’d ever take it this high!). Don’t worry, though, it has camera profiles to support raw files from all the latest cameras, too, like the Canon EOS R5 & EOS R6, Nikon Z6 & Z5, Panasonic S5, etc. and over 60,000 camera & lens combos for lens correction.

It even manages to handle astrophotography quite well, being able to distinguish between the difference between high ISO noise and stars rather well!

It also manages to pull back some pretty impressive detail in the shadows of images that’s otherwise quite difficult to make out, too.

It’s making me want to dig out my old Nikon D100 and see how well it handles anything over… Well, ISO200 if I’m completely honest (yeah, it really wasn’t great). Anyway, as well as the new Deep Learning AI-powered noise reduction, DxO PhotoLab 4 also sees a bunch of new workflow improvements to help you speed up your editing process.

First up is DxO Smart Workspace. This splits up all of the modifications you can do to an image by editing type (Light, Colour, Detail, etc), as well as offering a new favourites system to only display your most… Well, your most favourite modifications. After all, if there are things you use on every image and other things you never touch, there’s no reason to see them all at once, is there?

You can also limit the corrections and adjustments to only show by “Active” status. That is to say, if you’ve changed a setting, then they show up. If they’re still at their defaults, then they don’t, which means it really easy to see exactly what you’ve already done to an image without having to go hunting for it. And to make the hunting even less of a pain, there’s a new search feature (and, yes, it understands what the tools are called in other applications!).

PhotoLab 4 finally introduces some hefty batch renaming tools, which let you edit, search and replace filenames to manage your image library more efficiently. you also get selective copy and paste of attributes applied to an image. So, if you’ve just set a custom white balance at the beginning of your session, or you’ve pulled back the highlights to claw back those blown whites on your bride’s wedding dress, you can now selectively copy and paste those individual changes onto all the rest of those images without affecting everything else.

The edit history has also been expanded, allowing you to not only undo individual steps as far back as you like, but also allows you to deep-dive into presets you might apply to see each individual thing that preset changed in the process. You can even create a new version of an image from the edits history tab, too.

Watermarking (whether you’re for or against it is another debate and a different post entirely) has also been expanded and now offers the ability to use both text as well as images simultaneously using a variety of blend modes. So, if you want to brand with your logo, but have specific text for a session, now you can. you can also save watermark presets. And they don’t have to be enabled while you’re editing, you can work on your images at will, and then just have it bring them up when it’s time to export (very handy if you’re just sending over a bunch of web-sized proofs to a client that they haven’t paid for yet!).

Overall, it looks like a pretty significant upgrade over the previous version, and might just help you to both pull out an extra stop or two of ISO from your camera at a quality you deem acceptable, as well let you spend less time sitting at the computer after a shoot!
