Built around what the company claims is 'the fastest HDR engines available today' it allows real-time tone mapping and HDR manipulation. The software supports 380 Raw formats and works on them in 32-bits per channel to ensure image quality retention. Oloneo HDRengine is available at an introductory price of $59/€59 through the company's online store or can be trialed for 30 days for free.

Press Release

Oloneo® makes HDR photography accessible to all with the launch of Oloneo HDRengine™

HDR enthusiasts and novices can now benefit from the fastest, most advanced HDR tools packaged in a simple-to-use, affordable yet highly creative application.

Paris, France – December 16, 2011 – Oloneo today announced the immediate availability of Oloneo HDRengine, the fastest and most accessible HDR application to easily create superior HDR photos. Easy to learn and master, Oloneo HDRengine is designed for the HDR photography enthusiasts and novices and comes with ready-to-use contents to jump start the photographer’s creative process. Oloneo HDRengine v1 for Windows is available now at the special introductory price of US$59 / €59 through the Oloneo online store at A full-featured, 30-day-limited trial version of HDRengine can be freely downloaded from the company’s website as well.

HDRengine simplifies the process of creating and editing high-quality HDR images by offering an easy-to-use, intuitive workflow along with a full range of real-time tone mapping tools and options. Whether using multiple bracketed exposures or a single photo, HDRengine allows photographers to easily recover lost details in overexposed areas of a photo, restore low-light areas in underexposed photos, or create infinite variations of an image, from the most realistic look to the utmost creative tone-mapping style, without compromising details and color appearance.

Based on Oloneo PhotoEngine, the company’s flagship application for professional HDR and image processing, Oloneo HDRengine perfectly answers the needs of the beginners and enthusiasts looking for an accessible yet powerful application to create high-quality HDR photos quickly, without having to trouble themselves with the technicalities of HDR” said Antoine Clappier, President of Oloneo and main developer. “HDRengine is fast, easy to use and comes with many presets and automated tools to be productive instantly.”


Presets and automated tools: be productive instantly

Beginners will feel comfortable instantly thanks to a wide range of presets and HDR styles that can be previewed and applied in real-time. HDRengine also features many automated tools such as Auto Tone Mapper, auto contrast or auto alignment to rush the whole HDR process.

Blazing performance: revolutionary real-time HDR for a unique creative experience

HDRengine features the fastest HDR engines available today, allowing full real-time tone mapping and HDR manipulations, whether working with multiple exposures or a single photo. Real-time HDR means more time being creative and less time waiting for an image to refresh or a tool to respond.

Single image HDR: make your best shots even better

While HDRengine makes the tone mapping of bracketed exposures a very simple task, photographers can also dramatically enhance an existing single photo by using a large selection of HDR effects along with brightness, contrast, saturation and white balance controls.

Intuitive and responsive: easy to learn and master

HDRengine is an intuitive HDR application, easy to learn and master: the application’s responsive, elegant interface offers a well-organized and efficient workflow so each step of the HDR process is extremely easy to understand. Other notable features include instant raw photo and image thumbnails, full, real-time edition history with animated replay, full documentation and video tutorials directly accessible from within the application.


Best imaging technologies: no compromise on quality and precision

While aimed at beginners and amateurs, HDRengine share the same high-end image editing technologies and color model used in Oloneo PhotoEngine™, the company’s flagship application for professional HDR and image processing. This full real-time, 32-bit floating-point per channel (96-bit per pixel), ultra-wide gamut, full resolution and non-destructive image-editing engine is combined with Oloneo’s unique color model to guarantee photographers against any loss of image data and quality during the HDR process.

State-of-the-art HDR: make an impact with professional looking images

HDRengine offers the best possible tools to create spectacular, professional quality HDR images: three tone mapping engines, auto-exposure correction with fine-tuning, auto-contrast, halo control, ghost removal tools, auto-align, auto-orientation, and more.

Full raw and image file support

HDRengine handles over 380 different RAW photo formats, with thumbnail and preservation of key EXIF metadata, as well as the popular JPEG and TIFF file formats (export and import).

Works well for me. In fact it produces excellent natural looking results, better than I have been able to produce in HDR Efex Pro.
However the software appears to be in the early stages of development as there are still a few blips requiring regular restarting.

I've posted a comparison of what you get for $59 vs what you get for free, and the free soft wins by a huge margin:

By Sdaniella (Dec 23, 2011)

your link shows no software for free that handles HDR for single exposures...
you didn't tweak your single exposures for a HDR effect at all, and rather than let software run in 'auto' modes???
For JPEGs of course, I have zero RAW files.
For realtime custom tweaking live preview... not 'wait for results' in a guesstimate way.
not 'auto-HDR' (default???) effects of non-identical images (more than 1)...
but rather optimizing single exposures
shooting in 'default' is like shooting in 'AE' modes on a dcam/dSLR!!!

anybody else have great free HDR software for single exposure JPEGs with instant tweakable realtime MANUAL effects??? (please, no restrictions to 'auto' only modes please!!!)

btw... i tried SNS-HDR awhile ago... maybe have to revisit it with my old single exposed shots to see how instant it is or not.

sdyue, what are you talking about? -- every HDR software can work with single images, every soft can produce cartoonish HDR results through tone mapping -- it's the easiest thing to do. Hard thing to do is to use multiple exposures and produce natural well aligned, good resolution results. Oloneo is fast, nobody argues about it, but the image results and controls are also inferior to other alternatives, including free software.

By Sdaniella (Dec 21, 2011)

who offers free realtime HDR & WB preview for full screem image view (or close-up crop) for single exposed shot JPEGs???
i wanna know! i want it!!!
please share!

Impressive speed. But "Best imaging technologies: no compromise on quality and precision" -- Really? Images are quite unimpressive, neither as good controls or as good processing as other alternatives including free HDR software.

By Sdaniella (Dec 20, 2011)

been testing it...

it even has custom WB adjustable for JPEGs... which my camera mfr software doesn't offer at all except for RAW, so having this is like a finer version than what dcams and dSLR have for live preview in-camera... here, WB can be previewed in realtime while adjusting, and the entire image shifts accordingly.

and can revisit many of my old JPEGs that were not as optimally WB... for a WB revisit... :D

finally, software is as flexible as cameras for full image adjustment previews

now... if only cameras could offer 'full' flexible HDRengine instead!!!

Looks like their web site is down. I've tried several times, and never can connect. Must be a lot of people trying the evaluation software....

By Octane (Dec 19, 2011)

looks great. Still playing with it, but it is really fast! That's been my biggest issue with any HDR software I tried. Looks like they got that figured out!

By Octane (Dec 20, 2011)

After some more testing, WOW! I'm impressed. It really is amazingly fast and I don't even have the most up to date CPU. I also love the results. Awesome HDR software.

By FlyboySA (Dec 19, 2011)

Looks like it will be buggy......

Keeps on telling me it cannot activate the trail period as it cannot connect to the internet.... But I AM connected, 24/7.... Waste of time.....

Your Firewall or Antivirus is probably preventing HDRengine to connect. You need to allow the connection to start the trial period.

You can also contact us using the Support form located on our web site.

Thanks, but I am not sure that is the problem, it does not prompt me to allow a connection and even with the firewall and AV off it is the same....

Also tried it on a second computer on a different network, same result.....


By AbrasiveReducer (Dec 19, 2011)

Just when I thought I could junk the Dell for good, another interesting PC application. I like that you can start with overprocessed images with edges around everything, like the Stuck In Customs guy does and if you later decide you want something that looks like a photo, you just dial it down.

By Rriley (Dec 19, 2011)

the existing Oloneo Photoengine is great, and includes the HDR bit they are now offering as a standalone. It really is fast to use, and results are seen realtime, unlike say Photomatix. It is compatible with most RAWs and makes a good RAW converter on its own, and file transfer to your image editing software can be directly linked

One issue I have with current sensor applications is that every pixel is exposed for a predetermined "shutter open" time, and the light value is reported for every pixel, just like we used film! Now we should be able to do "exposure" differently.

To have an in-camera HDR would be relatively simple if only the camera makers would allow the shutter to be open long enough so that each pixel achieves some predetermined "exposure point", then simply report the TIME to that exposure point for each pixel. You could then obtain very high dynamic ranges, although "shutter open" times may be longish. The light values would then be reported as times rather than levels.

I predict sensors will be used in this manner someday....

patents already exist for pixel level exposure instead of whole image. it will take awhile for processors to go fast enough to handle all that variable data simultaneously.
also, it makes sense to have customizable selection of which pixels exposed to light levels have a custom chosen ISO, so we can have a realtime live pixel level controllable color 'zone system' we can SEE and decide individual sensitivities... it's close, the ideas for sure are already in the works, but not here yet, it is technologically limited by too slow processor speeds now.
we should be able to shoot max DR for 'single shots' that give us NaturalVision (something i've advocated for awhile here, or quite awhile back on dpr forums... it's been a long time, and all we get are crude HDR/DRO options, and HDR software to get us by for now)

By oscarvdvelde (Dec 21, 2011)

Exactly what I was once pondering about. That would work nicely for huge dynamic range for static subjects, but gives noise or artefacts for moving and flashing subjects. Imagine doing a bulb exposure waiting for a lightning flash, which happens after a few seconds. The high brightness then does not correspond to a very short exposure. So the sensor would need to be capable of both modes.

By Sdaniella (Dec 19, 2011)

HDR in realtime

If only dcams/dSLRs could offer REALTIME HDR exposure simulation live preview too... that's what's missing!!!

at first i thought something was wrong when opening my JPEGs, but realized i only had to choose the display preferences to match sRGB settings, instead of the default to my 'monitor' settings.

realtime HDR preview definitely helps one choose the 'effect' to be as natural as possible or as bizarre as possible (or avoid the latter); without realtime preview, its no wonder so many have that bizarre look (if one has to repeat settings just to get it right, one is more likely to get it wrong, thus bizarre looking)

i can SEE the boundaries of acceptable output relative to unacceptable output.

for the time being, testing this HDRengine on some of my more complex shots to see whether i can squeeze more out of them (JPEGS harder than RAW; but then RAW always looks wrong to start with even if perfectly exposed, so fixes are a must)

gr8.4.single exposures!

I may not be very smart, or maybe I am just too lazy, but my previous attempts at using one HDR software tool or another never went anywhere.

I never got anywhere with any of them. The free tools, etc.

But this afternoon I downloaded this software, and managed to figure out how to load my X100 RAW files into this tool (it's easy), and then just playing around with the "TM" slider bar, I got the thing to work.

I'm just amazed what can be done with my X100 RAW files.

After 2 hours, I was ready to buy. And I just did.

If you really push it, the images will look strange. But if you go easy, the images don't really have that "HDR look". Well, a bit, but they still look way better than what you'd have normally.

Maybe it's available for IPhone?

By mainvision (Dec 20, 2011)

Some software is available for the mac first (Adobe) or exclusively on the mac so yes, it sucks, but I will wait until it becomes available - unless there is better and newer software available at the moment. BTW, the price in € is much higher than in dollars, at today's exchange rate it should cost 77 USD or, if the dollar is the reference, 45 € - I prefer the latter option.

@Antoine: thanks for this clarification, although I will have to wait for the mac version, anyway. I see that, for Lightroom users, the Oloneo PhotoEngine has a plugin, but still Windows only.
