If only its raw processing was a little less noisy and as good as DxO's or Capture One's We complain that there's too much Photoshop doesn't do, but the fact is for many photographers this kind of old-school image-editor is exactly what they need.

And Affinity Photo gives you exactly the same thing, but subscription-free, via a single extra-low payment. Affinity Photo is sold at a budget price point, but it has the tools and the features and the power to compete with Photoshop head-on. Serif has focused particularly heavily on the retouching market, with cloning, healing and retouching tools, an Inpainting tool for automatic object removal and a dedicated Liquify persona workspace for localized image distortion effects.

Now up to version 1. Read more: Affinity Photo 1. Capture One works both as tethered capture and editing tool for studio photographers with a 'sessions' based workflow and as a Lightroom-style image cataloguing, searching and non-destructive editing tool.

One of the key differences is its layers-based local adjustment system which makes it much easier to see and edit your changes to your work, and this now includes 'parametric' linear and radial gradient masks which you can edit later. Fujifilm, Nikon and Sony users can get discounted one-brand versions of the software — but choose the all-cameras version if you work on files from multiple cameras. DxO PhotoLab is the replacement for the old DxO Optics Pro, adding local adjustment tools from DxO's acquisition of the Nik Collection software to make it a more powerful all-round photo-editing solution.

You use the PhotoLibrary window to browse your image folders, create Projects and carry out basic filtering and housekeeping tasks, but PhotoLab's real strength is its superb raw processing, amazingly effective DeepPRIME denoise tool Elite edition only , excellent local image adjustments and highly effective and automatic lens corrections.

The image quality produced by PhotoLab is second to none. Other programs still treat these as raw files with all the tonal and color headroom you would expect, but they have DxO's superior demosaicing, noise reduction and lens corrections pre-applied.

Silver Efex Pro remains the best digital black and white plug-in ever and is updated in this version with a fresh, modern interface, a new ClearView option and more powerful selective control points. Viveza gets the same treatment and is elevated from a relatively simple local adjustment tool into a much more powerful plug-in. And then there's Perspective Efex, DxO's most recent addition, which offers powerful lens and perspective corrections, tilt-shift effects and advanced wide-angle distortion correction.

The version 4. Read more: DxO Nik Collection 4 review. There's also an optional ON1 subscription service for Adobe style image sharing and synchronizing with mobile devices. ON1 Photo RAW has a built-in hybrid browsing and cataloguing module that gives you fuss-free exploring of your image folders but more powerful search tools if you need them. It has an Edit module with Develop, Effects, Portrait and Local adjustment panels, and the Effects module alone has a vast array of filters that can be adjusted, masked and combined in an infinite array of permutations.

It pulls off a particularly amazing trick, incorporating layers, masking and compositing tools into its fully non-destructive workflow. ON1 Photo RAW might not be as well-known as some rivals, but it's worth any keen photographer taking a look, especially with its fresh, crisp and modern new interface. Skylum Luminar is a relative newcomer to the photo-editing scene but it's made a big splash already.

Luminar AI offers a complete redesign on earlier versions, focusing heavily on AI effects and 'templates', automatically analyzing your images and suggesting some great looks. If you like the idea of an all-in-one photo-editor that can both organise your images and edit them with a fully non-destructive workflow, then you're in the right place! It even supports image layers, masks and montages. Luminar AI is a very powerful and effective mid-range photo-editor which is pioneering some very effective AI editing tools.

Its AI Sky Replacement filter is quite exceptional, and its portrait enhancement tools are more subtle and effective than ever you'd expect in an all-round image editor. It's just a shame that Skylum has stepped back from the more advanced approach in previous versions and placed so much faith in headline-grabbing AI tools.

However, without even a beta version to look at, we're not going to get too excited about software we haven't even seen yet. In which case, take a look at CyberLink PhotoDirector, which has a friendly and approachable interface that beginners will find it easy to get on with.

It doesn't offer image layers only adjustment layers , so you can't combine photos, but for many photographers that won't matter.
