stantang 寫:The keyword is "High Dynamic Range", JPG is LDRI which is "low dynamic range". Here is a page with an in-depth explaination of HDRI: http://www.trinisica.com/sub_learn_type ... &issue=002
Simply put it this way: LDRI normal has 8-bit color depth per channel, while HDRI has 32 or higher color depth. Meaning that it has much more color information than TIFF, JPG, etc... It has a much large room for color correct, exposure change, etc...
Many 2D and 3D programs support HDRI, even the latest PS CS 2.
