Few people would dispute the near-magical features of Photoshop, as well as ancillary apps like Lightroom and Camera RAW, but there has been criticism about its high subscription fees. However, there are plenty of challengers for the photo editing crown, especially on the Mac.

We take a look at some pretenders to the crown here, and their benefit is chiefly in terms of value for money - most charge one-off purchase prices, rather than monthly subscription fees, and some are ridiculously inexpensive considering what they offer.

Adobe, on the other hand, charges an arm and a leg. True, you can get just Photoshop and Lightroom for around £120/US$120 per year via the Photography subscription, but even this is considered by many to be a form of extortion.

Generally speaking, there are two categories of apps reviewed here: actual image editors, and image processors. The latter category includes apps designed to take images straight from a camera and improve them by fixing things like distortions introduced by lenses, or correct colour balance.

Some might include basic image editing tools, but they're not about unbridled creativity like the actual editing apps, which typically offer toolbars offering direct image-editing tools.

Many image-processing apps focus on improving RAW files, which is the data taken straight from the camera's image sensor prior to any processing taking place within the phone or camera itself. This offers the most scope for improvement because as much of the image data as possible is present and none has yet been discarded or manipulated.

For this group test we were only interested in professional products aimed at the photo editor who needs power and flexibility. But if you're looking to pay even less than this and can compromise on features, take a look at our roundup of the best free & cheap photo editors for Mac.

1. Affinity Photo

Although Affinity Photo might be priced at a level where amateurs can snap it up, its makers are keen to stress a professional feature set. You get CMYK and Lab colour space support, for example, which is a necessity when working accurately in the print design industry. RAW image support is built in, and the app claims the best support for Photoshop's ubiquitous .psd file format outside of Photoshop itself.

Affinity Photo is a power tool. Although it can indeed make subtle tweaks, just like any image editor, doing so feels like you're using a Bugatti Veyron to go to Sainsbury's.

With an asking price of just £48.99/$49.99, this app is a bona fide bargain. For semi-pro and even pro-level editing it really is a competitor for Adobe Photoshop.

2. Pixelmator

Pixelmator has a lot of fans in the Mac world, where its combination of amazing value for money plus extensive feature list makes it the most likely candidate for a swap-in Photoshop replacement. In fact, it's hard not to notice the influence of Adobe's product when working within Pixelmator: you'll certainly find most of its key tools, all within an interface that looks beautiful and fits in entirely with the macOS aesthetic.

This is not to say that every tool you might be used to is present in Pixelmator. For example, while Clone and Heal tools are present, there's no Patch tool, or Context-Aware Move tool, or History Brush.

However, none of this is an accident. Pixelmator deliberately keeps things simpler than Adobe's effort, which means it has found a home with amateur and semi-pro image editors who use it occasionally, rather than daily.

3. DxO OpticsPro for Photos

There's a lot to like in DxO Optics Pro. Our complaints are slight and revolve around the time taken to process the image when dragging it around while zoomed, as one example. Typically this was a couple of seconds, and on slower computers might be even longer. Additionally, there doesn't appear to be a zoom tool for quick zooming in and out, with the maximum zoom level capped at 200% too.

Other than Photoshop, DxO Optics Pro's nearest competition is Capture One Pro, but DxO Optics Pro is much cheaper and a lot easier to use too, relying largely on one or two sliders within each tool for the sake of simplicity. True, you don't get the incredible control over fine details that you do with Capture One Pro, but do you really need it? For simply pushing your RAW images so that you (relatively) quickly get the best out of them, DxO Optics Pro is a winner.

4. CyberLink PhotoDirector 9

PhotoDirector 9 is something of a dark horse among Mac photo editors because, initially, you might notice only its organising and sharing features. However, dig a little deeper and you'll find powerful tools for editing images, despite the app avoiding a toolbar-style approach and mostly eschewing the use of Photoshop-style pen/brush tools.

Positioned firmly in the semi-pro area, PhotoDirector 9 takes a fresh approach that means it's packed with features but operates unlike most other photo-editing apps we've looked at. Rather than take a tool-based approach, the app prefers to walk you through tweaks and edits.

You can almost certainly achieve the same things as you might with something like Photoshop - and perhaps more, such as the ability to tweak 360 degree photos - but it can be a little frustrating getting used to the app and finding where everything lives.

5. Capture One Pro 10

The price of Capture One Pro 10 indicates we're in professional photo-editing territory, an assumption backed up by the all-black user interface (somebody somewhere clearly decided that grey or white just weren't serious enough for pro-level Mac apps).

Capture One Pro exists to help those serious about photography create workflows that let them quickly eke the most from professional-grade images, as well as provide a permanent home for them. It has the feel of a reliable and sturdy tool - a kind of De Walt of the image editing world - and we doubt you'll find anything more powerful. However, the sheer number of controls and the subtle degrees of adjustments can feel like a labyrinth.

For the more casual day-to-day image editor - and for pretty much anybody beneath scrupulous professionals who need to ensure perfect images - it's actually quite hard to recommend Capture One Pro. If nothing else, the price is high and you'll need top-end colour-matched equipment to even begin to get the best out of it.

In many ways Acorn feels and even looks like a snapshot of Photoshop from a decade or two ago - with a selection of the more modern and useful Photoshop tools mixed in too. You get all the tools that made Photoshop so damned useful in the first place, such as levels and curves to adjust an image's brightness/contrast, as well masking and layers, and various filters.

However, while you avoid the modern-day cruft, you also miss out on the rare useful innovations that have come along, like the heal and patch tools, or advanced selection tools that let you select by colour range, amongst other things.

If you're one of those people who long for the days when software was simple and kept out of the way then Acorn is for you. The price is pretty competitive too.

However, it's hard for us to commend Acorn when something like Affinity Photo or Pixelmator offer substantially more image editing flexibility and power, yet are also still easily within the budget of professional or enthusiast users. Ultimately, Acorn is very good, but its competition is simply better.

On macOS the GIMP looks alien and its interface feels overly complicated; it can be baffling working out how to use its tantalising feature set. GIMP isn't a clone of Photoshop, nor does it want to be. There can also be some glitches.

But familiarity will build, and there's much to recommend GIMP. Especially if you literally can't afford to spend any money but still need genuine image editing power above and beyond applying silly filters to images. We're grateful GIMP exists simply for this reason.

Is Fotor Photo Editor a Photoshop clone or wannabe? Not even close. It is to Photoshop what a ZX Spectrum is to the iMac Pro: a relative, perhaps, but laughably not in the same league.

However, there are some powerful tools built in that belie the free price tag, and considered for what it actually is - which is an image tweaker and improver, like those countless apps for your iPhone; one-click filters and fixes are the order of the day - then it's actually very good.

But rather irritatingly, several very useful features require you upgrade to Fotor Pro; if you don't, a watermark is placed over the image when you use the tool in question. And whether you'd want to spent £17.99/$19.99 a year to upgrade is questionable, especially if you're looking for high-level image correction and editing.

There are lots of one-click Mac image editors out there, but typically they're aimed at the lower end of the market. Movavi Photo Editor has one foot in this camp but has some tools that could make it a useful installation for professionals.

Chief amongst them is Object Removal, which lets you define an area of the image that will then be magically removed. Everything from facial blemishes to telegraph wires to photobombing seagulls can be eradicated by using the provided brush tool to draw over the object, and the results are excellent.

However, other tools we tested were less impressive; filters, for instance, take several seconds to be applied. There might be promise in this approach but it's not there yet.

Movavi's price puts it in the same bracket as the likes of Pixelmator or Affinity Photo, both of which are simply several times more impressive and useful, and are to be recommended instead.
