Since the beginning of High Dynamic Range processing HDR applications have been applying the same, one size fits all, tone mapping curve to all HDR merged files. But your HDR images are not like everyone else's and wouldn't it be great if your HDR application could analyze each of your individual HDR images and apply just the right amount of tone mapping for the best image possible? Unified Color's Adaptive Tone Mapping does just that.

Old Tone-Mapping Algorithm

NEW Adaptive Tone-Mapping Algorithm

Tone mapping in other applications applies a single, linear curve over the whole image that could optimize processing for shadow detail at the cost of highlights or vice versa. Our breakthrough Adaptive Tone Mapping creates a custom localized adaptive tone mapping curve for each individual image thus enhancing the contrast of your image's individual tonal zones. As you can see in the graph HDR Expose 3 will analyze your image's histogram and determine exactly which areas of your image need more or less contrast enhancement (tone-mapping). This retains the detail and color in the highlights and shadows at the same time.

HDR Expose 3's new Adaptive Tone Mapping Gamma adjustment function is a sophisticated improvement on traditional tone-mapping techniques. Often in HDR tone-mapping you'll get your highlights set to perfection but your mid tones and shadows will still need some improvement.

The Gamma adjustment slider does just that. As seen on the chart below, the green curve represents the default automatic adaptive tone curve. Adjusting the Gamma slider up or down changes the angle of this curve essentially brightening or darkening the image while retaining the overall contrast of the image for the perfect tonal relationship between highlights, mid-tones and shadows.
