Is there a way to tell the actual dynamic range of an image in Photoshop? If I convert an HDR image to SDR, I want to check how much dynamic range, if any, would be lost. Also, is there a way to have warnings in Photoshop when things like highlight clippin...
Enhancing image dynamic range is described. An input video signal that is represented in a first color space with a first color gamut, which is related to a first dynamic range, is converted to a video signal that is represented in a second color space with a second color gamut. The ...

Dynamic range photography is the right balance between dark and light image. Adjust your f-stop to capture High Dynamic Range photography.
In Adobe Photoshop, learn how to work with high dynamic range (HDR) images. These images can represent the entire dynamic range (ratio between dark and bright regions) in the visible world.
点击“Process Image(生成图像)”按钮,然后它会将你的设置应用到你的HDR图像。处理完成后,你可以保存你的图像。我建议你保留所有信息,所以把它保存为16位的TIFF文。Photomatix允许你直接在保存面板处直接将保存后的图像发送到Photoshop来做最后的微调。我通常做一些整体设定,然后根据需要进行减噪或锐化。
Dynamic range refers to the range of brightness levels in an image. High dynamic range (HDR) images attempt to capture the whole tonal range of real-world scenes. Display High Dynamic Range Image This example shows how to convert HDR data to a dynamic range that can be displayed correctly ...
1 Deep High Dynamic Range Imaging of Dynamic Scenes 现有HDR技术首先将输入图像对齐到参考图像,然后将对齐的图像合并得到HDR图像。然而,在最终的HDR图像中,对齐的artifact通常以重影和撕裂的形式出现。 而该论文发现,在合并期间,对齐的artifact可以显著减少,它需要检测带有artifact的区域,并将它们从最终结果中排除。
