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 :)

Even the example photo here shows the flaw in this app

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.

Ok, but...

This claims to make an HDR photo out of a regular photo. It doesn’t. What it does do is try to lighten the shadows and/or darken the highlights. In the auto mode there is a shift in colors in the shadows. It also adjust too far. In the manual mode you can slide back the shadows to make them not so exaggerated. In a real HDR photo several different exposures are combined to get the High Dynamic Range. If you have use a simple photo editing program this is just changing the the highlights and shadows to bring the values closer together. In the Gray mode you don’t get the color shift because there is only black and white. This can save some photos but I would always switch to the manual mode to see if you can do better than the auto settings. There are some filters, such as cartoon or gray, that stylizes your photos.

Navigation improvements would move this into four or five star territory

Many others have addressed the functionality of the app and filters, I don't have much to add there.

What I do have to add is that there are some basic navigational issues. When composing a photo if the shot isn't what the user is after - the "+" sign allows a new photo to be takenwithout saving the current photo.

This was not intuitive to me. Seems more logical if that were an "x" to better indicate the desire to escape or close the current view/window so that I might take a new photo.

Also in the "⭐️" filter area, it appears that any selection will immediately overwrite any changes a user might have made manually. A preview mode for filters, or a way to return to cutsom adjustments would be appreciated.

Just a little finesse on the interface would push this into four or five star territory.
