OrasisHD is a 1-shot HDR app. It takes a SINGLE image and automatically transforms it to a well-exposed, natural-looking photo, simulating the way your eyes perceived the scenery at the moment the photo was taken. Based on a decade of academic research, OrasisHD uses a proprietary image processing algorithm: dark and bright image regions are enhanced, revealing information that was not visible previously. More importantly though, well-exposed areas are not affected! To the best of our knowledge this is a unique feature not offered by any other app in the industry. If you are not sure that OrasisHD is good for you, please try our FREE version (Orasis), before purchasing OrasisHD. Our customer base consists of satisfied users, and we do not intend to change this any time soon :) ## Key features - Single-shot HDR processing - Automatic exposure enhancement - Natural-looking photo simulation - Reveals hidden details - Preserves well-exposed areas ## Recent user reviews (10 of 51) All indexed reviews: https://appshunter.io/ios/app/orasishd/id454408758/reviews.md ### 5/5 — Excellent application *2023-07-01* It makes amazing things to a photo. Easy and most of the times the default settings are more than sufficient. Highly reccomented ### 5/5 — A great for iPad and iPhone pictures. *2021-12-11, version 3.51* Brings dark areas out of shadow. Emphasizes colors. Wonderful. I use it after I’ve edited and cropped in other programs. OrasisHD is a key part of my #iphonery. ### 5/5 — I love this app. *2021-09-18, version 3.51* It works well, they are generous with what you can do in the app and I'm grateful. :-) ### 3/5 — Even the example photo here shows the flaw in this app *2020-03-18, version 3.34* It is trying to balance everything from the darkened image which is too dark for this app to edit. It brought up the grain and oversaturated the rest of the photo to try to make up for it. I’m sure if the app designer were to redo their photos, maybe not from the same vacation, but similarly nice setting they would use the flash to light their subjects in the darker foreground and the app can then have more light to allow the photo to look like how the eye perceived it. The photo end result above doesn’t make me want to waste the space on my phone. I don’t want to bash the Dev’s hard work totally. Not even gonna one or two-star it. But please fix the image you submitted. I bet your app works fine with normal lighting situations. Where the lighting is not as extreme between the subject and scenery. But the one above, was just under-lit in the foreground and the final edit was not the best choice to show with the end result requiring a few more apps to try to repair it and possibly degrade it further. This image could be in the app manual showing the limits of the app to users show how to obtain best results and where the limits are. Then show the newer young photographers how to get the best daylight images. It’s hard to fill in data for light that isn’t there . Sometimes you must over-expose the image a bit then let the app darken it in post. ### 5/5 — Works *2020-02-27, version 3.34* It works well but could use updated. The auto mode severely over saturates. You can correct it in the editor but time gets wasted having to do it. Overall the app does a good job. But you do have to learn how to use it as it is a little wonky. But the results will be worth the time to learn the apps strengths and weaknesses ### 5/5 — Good auto adjustments *2019-07-16, version 3.33* ‘Contre-jour’ photos are effortlessly corrected. You are able to manually correct, but the auto feature truly removes the guesswork in adjustments. Good app. ### 5/5 — Incredible enhancements *2019-07-10, version 3.33* There are so many photo apps. This is the first that I’ve tried that makes a dramatic change in my close up shots of models, automatically. The app design is not 5 star material but the degree of photo improvement is so dramatic it demands 5 stars for that feature, alone. And to do so automatically is a huge time saver to those of us who are not skilled photographers. ### 5/5 — Awesome *2019-07-06, version 3.33* Very easy to navigate the functions of this app. ### 5/5 — quick and easy way to brighten dark pictures *2019-03-22, version 3.32* I love this app. So much easier to lighten dark pictures with this app than using the robust but complicated tools that are available-and which I have. Orasis is an important, go-to tool in my graphics tool box. ### 4/5 — Better than iPhone camera *2019-03-08, version 3.32* This app takes really great photos in hard to shoot places. It is not easy to figure out how to use and having to save before each new shot makes it not handy. Would love to see it easier to use. ## Frequently asked questions about OrasisHD ### What does OrasisHD do?
