  1. What is HDRI mapping in photography? 2008-07-26 11:38:49

    HDRI in photography is High Dynamic Range Imaging. Tone mapping for HDR is described well on http://www.hdrsoft.com/resources/dri.html#tone_mapping where is says [quote]"Tone Mapping is the process of converting the tonal values of an image from a high range to a lower one. For instance, an HDR image with a dynamic range of 100,000:1 will be converted into an image with tonal values ranging from just 1 to 255.
    You may wonder why someone would want to reduce the tonal range when an HDR image provides so many benefits compared to a Low Dynamic Range image. After all, HDR images contain a much higher level of detail and are closer to the range of human vision. The reason is simple: standard display devices can only reproduce a low range (around 100 or 200:1), and for paper, the range is even lower.
    So, the goal of Tone Mapping is to reproduce the appearance of images having a higher dynamic range than the reproducing media such as prints or standard monitors. "[/quote]

    By spherical, do you mean stereographic panoramas...?

    You can get a software for making the equirectangular: Kolor Autopano Giga 2.5

    And then a Plug-in for Photoshop to make a stereographic pano: Flexify 2
