Editing photos

In photography, HDR refers to “high dynamic range”. Dynamic range is the range of luminance that can be captured in a photo, from the darkest shadows to the brightest highlights. HDR processing lets you combine two or more RAW photos of the same scene that have been taken with different exposure settings. Best results are achieved when the photos are taken with a tripod or very steady hand. An auto-bracketing feature on your camera makes it easy to capture sets of photos at different exposures. For high contrast scenes, such as sunsets or a photo of a room interior with a large bright window, HDR processing merges photos and creates a more even exposure that lets you resolve details in the darkest areas without losing definition in the bright areas.

Corel AfterShot HDR

Corel AfterShot HDR has three components that let you achieve HDR results:

•	Exposure Merge -- lets you merge one or more photos to achieve an HDR effect. You have access to presets and custom controls to get the results you want.

•	Single RAW Photo -- lets you simulate an HDR effect from one RAW photo by using HDR tools.

•

Batch Merge -- lets you merge one or more sets of photos, normally captured on a camera that uses an auto-bracketing setting. This feature offers a fast way of merging multiple sets of photos. There are very few controls. It's a great way to identify sets of photos that you might want to fine-tune in Exposure Merge.
