Best HDR Photography Software of 2018: Unbiased Reviews

The digital camera is an incredible and complex device, allowing us to capture everything from vast landscapes to incredibly personal moments. But for all its capabilities, it still can't quite compete with the abilities of the human eye for one important reason: our brain.

When you look out at a beautiful sunset, your eyes adapt to limit the amount of light they receive. At the same time, your brain remembers what was happening in the darker areas of the scene in front of you and stitches it in, creating the illusion of being able to see a very wide range of contrast. Your eyes aren't really capturing everything all at once, but the switchover between the bright areas and the dark areas happens so quickly that you don't usually notice it.

Digital cameras can't really accomplish the same thing on their own, which means that when you expose a photograph perfectly for the clouds, your landscape tends to appear too dark. When you expose for the landscape, the sunset appears too bright and washed out. Fortunately for photographers, it is possible to take multiple different exposures of the same shot and combine them into a high dynamic range (HDR) image.

There are tons of different pieces of software available to accomplish this, but they're not all created equal. I finally selected HDR Darkroom 3 and Aurora HDR as the best HDR photography software available, although I looked at quite a number of options for this review which we'll discuss later on.

HDR Darkroom 3 is better suited to quick compositions where you want to expand the dynamic range of your images slightly without getting worrying too much about perfect realism. It provides quick, easy to use options that are perfect for photographers just beginning to experiment with HDR images, or for casual users who want to have a bit of fun with their photos. It is by no means a professional program, but it's still a great introduction to the world of HDR.

Aurora HDR offers an impressive set of features with an in-depth level of control for the more demanding photographer. It is far better at creating realistic HDR images than any of the other programs that I reviewed, but that also means that it requires a bit more skill to use successfully. It's still possible to create surrealist paintings out of your HDR photos, but it's also possible to turn them into realistic HDR masterpieces.

Why You Should Trust Me

Hi, my name is Thomas Boldt, and I've been interested in HDR photography since I got my first digital SLR camera over a decade ago. I always wanted a camera that could accurately capture what my eye saw in its complete form, and I was frustrated with the available native dynamic range. This started me on a journey into the world of HDR, although it was relatively new outside the laboratory at that time. The camera's automatic bracketing was limited to only three shots, but that was enough to kickstart my interest and I began to explore the HDR compositing software that was available.

Since then, both digital camera sensors and the software have improved dramatically, and I've been keeping tabs on the available options as they matured into fully-developed programs. Hopefully, my experience will be able to guide you away from time-consuming experimentation and towards an HDR compositor that really works for you!

A Few Truths About HDR

Attempts to expand the dynamic range of photographs are nothing new. Believe it or not, the very first photographic composites designed to expand dynamic range were made in the 1850s by Gustave Le Gray, but naturally his attempts were crude by today's standards. Legendary landscape photographer Ansel Adams used dodging and burning techniques in the darkroom to achieve a similar effect from a single negative during the mid-1900s.

The advent of popular digital photography created a resurgence of interest in HDR photography, as digital images could be composited much more easily with a computer program. At that time, digital camera sensors were very limited in their dynamic range, so HDR was a natural thing to experiment with.

But as with all digital technologies, digital photography has progressed by leaps and bounds since then. The dynamic range of modern camera sensors is far better than 15 years ago, and continually improves with each new generation of camera.

Many programs can reclaim highlight and shadow data from a single image, without needing to combine multiple exposures. The highlight and shadow recovery tools available in most RAW editors can do a great job of expanding the dynamic range in a single photo without having to fiddle around with image stacking, although they still can't accomplish the same improvements as a widely-bracketed set of images.

It's also worth noting that true HDR images cannot be displayed natively on most monitors, although now HDR TVs and monitors are finally becoming available. However, even still, most of your outputs from any HDR app will be converted down to a standard dynamic range. In essence, this creates an HDR-style effect without actually saving your image as a 32-bit HDR file.

I don't want to get too technical about the inner workings of bit depth and color representation here, but there is an excellent overview of the subject from Cambridge In Color here. Unexpectedly, since this isn't exactly their main focus, the Android Authority website also has a good roundup of the differences between HDR and non-HDR displays which you can find here.

Feel free to read up on the technical side if you want to, but it's not necessary for you to enjoy HDR photography. For now, let's take a closer look at whether or not you'll benefit from working with HDR.

Do You Really Need HDR Software

Like most technical questions in photography, the answer to this comes down to the type of photographs you shoot and how dedicated you are to photography in general. If you're a casual photographer, then it's probably best to experiment with some of the demo versions and free options before you purchase a dedicated HDR program. You'll have a bit of fun (which is always worth it), but in the end you'll probably want a simple, easy-to-use HDR program that doesn't get too technical or overwhelm you with options.

If you're an aspiring amateur, working with HDR is an interesting way to expand your photography practice and technical know-how. Just be careful not to overprocess your images if you want them to be taken seriously - they always stick out like a sore thumb to the experienced eye!

If you're working in the world of professional photography, you won't necessarily benefit from HDR shots, but it's more likely that you will appreciate what can be accomplished with a great composite in your specific field.

Anyone who shoots static images in high contrast environments will benefit from HDR, depending on your choice of subject. Landscape photographers will get a real kick out of their first perfectly-exposed wide angle HDR sunset, and may find that they never want to go back to a single frame photography style. Architectural photographers will be able to capture dramatically-lit scenes with ease, and interior/real estate photographers will also benefit from the ability to show both the interior and what's out the window in a single frame.

If you've been managing these types of professional shots without the benefit of HDR so far, then you obviously don't need HDR software - but it might make things much, much easier!

The Necessary Features

There are a great number of HDR programs available, and they vary quite a bit in terms of capability and ease of use. Here's the list of criteria we used when evaluating each program and selecting our winners:

Are the tone mapping options comprehensive?

This is the most important aspect of a good HDR program, because in order to be saved, your 32-bit HDR image usually needs to be tone-mapped into a standard 8-bit image format. You should be able to have complete control over how the tones in the different source images are combined into your final image. Does it align images properly? Unless you're shooting your series of bracketed images with a tripod, there's usually a small amount of variation between each of the frames. When merging the images, your HDR program should be able to correct for these small discrepancies automatically, or you'll wind up with a very unappealing series of edge overlaps in certain parts of the image.

Does it do a good job at deghosting?

Of course, your camera might not be the only thing moving over the course of a bracketed set of images. Wind, waves, clouds and other subjects can shift enough during a burst shot that they are impossible to automatically align, resulting in what are known as 'ghosts' in the HDR world. A good HDR program will have reliable automatic deghosting options with a precise level of control over how they are applied to your image.

Is it fast and responsive?

Combining multiple images into a single HDR image can be time-consuming, especially when you're working with a large number of high-resolution images. With a properly optimized application you should be able to get your initial composite quickly, and the editing process should be responsive without long recalculation times each time you make an adjustment.

Is it easy to use?

Even the most complex application can be easy to use if it is well-designed. A badly-designed program becomes frustrating to use, and frustrated image editors are rarely productive image editors. A clean, clear interface is a major factor when choosing a program you're going to be using regularly.

Does it offer any other editing features?

You probably already have an established workflow for editing your photographs, but it can be helpful to have some additional correction options within your HDR app. Basic corrections such as cropping, lens distortion adjustments or even some localized editing features are a nice bonus, even if they are not required. You may feel more comfortable doing that type of adjustment using your current editor, but workflows tend to be faster when using a single program.

Is it compatible with Windows and macOS?

It's always frustrating to hear about a great new program, only to discover that it's not available for your particular operating system. The best programs with the most dedicated development teams usually create versions of their software for both Windows and macOS.

Note: During each review, I tested with a number of my own HDR images. For the sake of consistency, I've included screenshots of each program's composite of the same images, which are provided as sample images in Aurora HDR.

The Winner's Circle

Best HDR Photography Software for Professional Photographers: Aurora HDR

Aurora HDR has been available on macOS for a while, but it has finally released a Windows version and I was eager to get a chance to test it out. You can get a free trial from their website (scroll to the bottom to find the link), although you will have to provide an email address and they will email you a download link. It's a bit of extra hassle, but it is definitely worth it!

The interface for Aurora HDR is extremely polished, to the point that it makes all the other programs I reviewed look clumsy and awkward by comparison. The main preview window is surrounded by controls on three sides, but it's all well-balanced so nothing feels overpowering despite the impressive number of settings you have to work with.

The tone mapping options are by far the most comprehensive of any program I looked at, although it will definitely take a bit of time to get used to them all. There is a full-fledged set of localized non-destructive editing tools, complete with dodging/burning and adjustment layers with brush/gradient masking options.

For the most part, Aurora HDR manages to stay fast and responsive while juggling all these tasks. You could definitely slow it down by working on a very high-resolution file with a few extra layers, but the same thing will happen even in Photoshop no matter how powerful your computer is.

The only issues that I had when testing out Aurora HDR were relatively minor, although they seemed a bit odd when you consider how well-developed the rest of the program is. The process for browsing and opening your source images is nothing more than a standard 'Open File' dialog box with very limited browsing capabilities, which is adequate, but only barely. Once you've selected your images, there are a few optional (but important) settings that are inexplicably hidden within a menu instead of being front and center. Aurora makes up for this partly with some helpful explanations of each setting, but it would be far simpler to include them in the main dialog box.

Aurora HDR was designed in conjunction with professional HDR photographer Trey Ratcliff, and the developers have clearly committed themselves to going above and beyond. This is far and away the best HDR app I've used, and I've tested a great many of them. Professional photographers will find more than enough to satisfy them, although the degree of control may put off the more casual photographer.

At $99 USD, it's not the cheapest option out there, but you get quite a lot of value for your dollar. Both Windows and macOS versions are currently on sale for $79 USD, which makes it even cheaper than our 'beginner' option. There is no word about how long this sale will last, but it may be on 'semi-permanent sale' as a marketing tactic.

Nicole reviewed an earlier version of Aurora HDR for macOS, and you can read the full piece here on SoftwareHow for a closer look.

Best HDR Photography Software for Casual Users: HDR Darkroom 3

HDR Darkroom 3 may not be the most powerful HDR app out there, but it is definitely one of the easiest to use. The 'New HDR' button gives you a quick overview of how to add photos, as well as some basic options for aligning images and deghosting. Choosing 'Advanced Alignment' increases the time required to load your initial composite, but it takes more time to ensure things are correct. Unfortunately, the 'Ghost Reduction' option offers no settings at all, but that's part of the simplicity of the program.

The interface first loads your image into a basic preset mode with very simple control over saturation and exposure, but you can click the 'Advanced' button to dig much deeper into your tone mapping controls and general exposure options.

The default 'Classic' preset style shown above in the Basic interface mode clearly needs some adjustment for this shot, but the 'Advanced' controls (shown below) offer the flexibility to clean the image up fairly successfully. Despite the lack of any localized editing tools, they offer you a decent amount of control over your image, and throw in some basic chromatic aberration correction for you as an added bonus. As most beginner photographers aren't using top-of-the-line lenses, the CA correction is quite helpful.

The editing process is fairly responsive, although there is a bit of a lag time between entering your new settings and seeing the results in the preview window, even on this powerful testing computer. Even after the edits, there are some slight halos around the clouds and some of the trees, but that's a legacy of the limited deghosting options I mentioned earlier. This problem might not occur on a shot with more static elements, but the image quality isn't the same as what you'd get from a professional HDR program. To prove the point, I've run the sample images from Aurora HDR through HDR Darkroom below.

Even with a saturation boost, the colors aren't quite clear enough and some of the contrast definition in the smaller clouds is missing.

HDR Darkroom isn't the cheapest option at $89 USD, but it is a good way for beginner photographers to start experimenting with HDR photography without being overwhelmed with technical details. If you're looking for something with a lot more power, be sure to check out Aurora HDR, especially if you can get it on sale for just a few dollars more. 

Honorable Semi-Free HDR Software Mention: Nik HDR Efex Pro

This is a great little HDR app, but it is only available as a plugin for Photoshop, Bridge or Lightroom, which have their own subscription fees. The tradeoff for that limitation is that Google has released HDR Efex as part of the Nik software plugin collection completely free of charge.

The interface is well-designed and easy to use, especially when you consider the plugin is free. The alignment and deghosting options are fairly standard during import, and you do get a bit of choice as to the strength of the deghosting effect. There are some basic but useful tone mapping tools, although each control over the HDR method is limited to a few options. HDR Efex offers some localized editing features, but the control point system it uses doesn't offer the same level of control as a brush-based mask.

If you already have an established workflow in Photoshop and/or Lightroom that you're satisfied with, you can incorporate HDR Efex directly into those programs to replace their basic built-in HDR tools. This gives you the advantage of having your familiar editing tools right at hand without the hassle of having to switch programs to complete the rest of your edits - and you sure can't argue with the price.

The Paid Competition

Photomatix Pro

Photomatix has been around for quite some time, and as a result it has a well-developed set of tools for editing HDR images. There are comprehensive alignment and deghosting options, and you can even apply lens corrections, noise reduction and chromatic aberration reduction during the import process. You get a decent amount of control over your tone mapping, and there is a range of presets available (including some that don't make your photo look unrealistic!).

There are some brush-based local editing features, but they caused the only discernible lag in responsiveness I found while testing. They are also fairly limited and difficult to review/edit once you've defined your mask, which is largely caused by the main drawback of Photomatix: the unpolished user interface. It's a great program with great capabilities, but the interface is quite clunky and gets in the way. Individual palette windows are all un-docked and scaled to odd sizes by default, and when you minimize the program the Histogram window sometimes stays visible and can't be minimized.

The presets aren't completely visible on the right, for some reason

Photomatix is available for Windows and macOS from the HDRSoft website here. At $99 USD, it's one of the more expensive programs we looked at, but there is a free trial available so you can give it a try for yourself before making a decision. All your images made using the trial version will be watermarked, but you can use it for as long as you like.

EasyHDR

Despite the name, EasyHDR has a very comprehensive set of options for editing your HDR images. The tone mapping options are decent, and there are excellent options for controlling alignment, deghosting, and lens corrections during the import process.

When working with some images I noticed that the default settings looked a bit over-processed and unrealistic, but it's possible to adjust these settings and save new presets.

If you want more localized editing options, EasyHDR has an excellent set with clearly editable brush and gradient masking tools and multiple layers. The only unfortunate aspect is that the 'Enable/disable layers' option limits the preview window a bit. Editing tools are fast and responsive, as are all the other steps involved in creating an HDR image.

EasyHDR is one of the most affordable programs we looked at, costing just $39 USD for home use or $65 for commercial use. It doesn't offer the same level of control that a demanding professional photographer would want, but it's an excellent mid-range program with great value for your money.

EasyHDR is available here for Windows or macOS, and there is also a free trial available. The trial doesn't limit you in terms of time, but it does restrict you to saving your images in JPG format and applies a watermark to all images you create with it.

Oloneo HDRengine

After being disappointed by the lack of internal file browsers in other programs, Oloneo has unfortunately proven that a badly-implemented browser is worse than no browser at all. It uses an Open Folder dialog box to select your source folder, but you're forced to use it every time you want to change folders which gets quite frustrating if you're searching for something.

During the import process, there is a basic 'auto-align' option, but the two deghosting methods are unhelpfully named 'method 1' and 'method 2', with no explanation of the difference between the two. Once it's time to edit your HDr image, there are very limited tone mapping options, and no localized editing features at all.

I don't like being mean in my software reviews, but I have to say that this app feels a bit more like a toy or a programmer's learning project than a serious HDR program. Despite the basic tone mapping options, the developers took the time to incorporate a 'Play' button that uses your edit history to automatically display all of your edits in sequence as a sort of time-lapse movie in the preview window.

It must be said that HDRengine is quite fast and responsive - which is part of how it pulls off that 'edit history movie' trick - but that doesn't really seem like a worthwhile tradeoff. There is a 30-day free trial available from Oloneo here (signup required) if you want to test it yourself, but I recommend that you look at the other programs first. The full version costs $59 USD, and it is available for Windows only.

HDR Expose

HDR Expose has a slightly confusing system for opening files, because it asks you to browse to a single folder at a time to review your images. This was time-consuming for me, since I have my images sorted into month-based folders, but it allows for a surprising and unique feature: when browsing your images, HDR Expose tries to automatically stack them into sets of bracketed images by comparing the thumbnails of each image. It wasn't always perfect, but it can be helpful when you're sorting through hundreds or thousands of photos to find your bracketed set.

The manual alignment and deghosting tools are quite excellent, allowing a great deal of control in addition to the automatic options. The tone mapping options are decent, covering the basic range of exposure controls you would expect. It has some basic local editing tools in the form of dodge/burn brushes, but they don't use individual layers which limits their effectiveness.

The interface is basic but clear, although some of the controls feel a bit oversized thanks to the unnecessary highlighting around each element. It was fairly quick when creating the initial composite, as well as when applying updated changes. The only time it ran into trouble was when I tried to apply too many Undo commands in rapid sequence, even going so far as to blank out the UI for a few seconds, but eventually it came back.

The Free Competition

Not all HDR programs cost money, but there is often a bit of a trade-off when it comes to free software. Here are a few free HDR programs that you might want to consider if you're on a tight budget, although they usually don't provide the same quality as you'll get from a program with a paid developer.

Picturenaut

Picturenaut is a quintessential free image editing program: it does what it says it will do, and not much more. It includes basic automatic alignment and deghosting options, but almost all of the tone mapping and editing settings are defined before you actually create your HDR composite. Needless to say, for most photographers, this will not provide nearly as much control during the editing process.

Picturenaut failed to identify the correct EV differences between the source images from the existing EXIF data, and asked me to input correct values by hand

The compositing process was quite fast, but that's probably due to the limited nature of the options available. You can do a bit of basic editing afterwards by opening the Tone Mapping window, but the controls are as basic as possible and nowhere close to what you find in other programs. 

As you can see above, the end result is definitely in need of some additional retouching work in another editor, although even putting this composite through Photoshop won't restore the kind of control that you need to create a really stunning image.

Luminance HDR

At first glance, Luminance HDR appeared to be a much more successful free HDR program. The interface was clean and simple, and it correctly identified all the relevant data from my source images. There are decent alignment and deghosting options, and the software seemed fairly responsive - at least, until it came time to complete the composite process, when the entire program crashed.

A second attempt was more successful, although I disabled auto-alignment and deghosting, which may have been the original problem. The interface has a few nice touches, such as an EV based histogram which shows the proper dynamic range, but the rest of the options are fairly confusing.

There is a range of tone mapping options, but no explanation of the various 'Operators', and the image preview must be manually updated every time you make a change to the settings. With some additional work and polish to the UI, this could be a decent free HDR program, but it's not quite ready to challenge even the most basic of our paid alternatives yet.

Fusion

Fusion has two versions, one free and one paid, and while the free version comes with a lot of limitations, it actually created the best composite out of all three free programs I included in this review. The settings are offered with zero explanation and don't always correspond to the names typically used in image editing programs, but the results are better than some of the more basic paid programs I reviewed.

There are no alignment options, and a very basic deghosting control, so you'll probably only want to use this with images shot using a tripod. The default settings are very desaturated, but with some adjustment you can create a good quality image. The processing wasn't always instantaneous, but it was fairly responsive all the way through. If you're not interested in using Nik HDR Efex, this is your best free HDR option, although it's only available for Windows.

You can download the free version of Fusion here (scroll to the bottom for the free version link).

A Final Word

High dynamic range photography can be an exciting hobby, as long as you don't have to fight against your software to get high-quality results. As you may have noticed in my review of many of these programs, the focus on the mathematics behind HDR has often turned the image quality and user interface into secondary considerations - at least, from the perspective of the software developers. Fortunately there are a few diamonds in the rough, and hopefully one of these great HDR programs will help you explore the world of HDR photography!
