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 :)

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.

Works well

There is a learning curve. Its well worth the time to master the interface. This app will allow some impossible problems to be over come. When this app does it's thing you have super dynamic range with reasonable resolution of minor movements. Use it for those occasions when there is no right exposure for all the photo. I cannot live without it for that impossible exposure problem. Hoooooaaaaa!

quick and easy way to brighten dark pictures

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.
