Cheers for visiting my blog!
That is ...Hey Andy, <br /><br />Cheers for visiting my blog!<br /><br />That is indeed a really a great insight into the origin and the process! You must really have been in this industry for a long time to know things like that.<br /><br />I will definitely read more into the wedging process you've just mentioned, and the "morgue" too! ;)<br /><br />Thanks again!Patrick Woohttps://www.blogger.com/profile/13651060214845014912noreply@blogger.comtag:blogger.com,1999:blog-1071488169957913341.post-91658655515134697842012-02-15T04:44:29.662+08:002012-02-15T04:44:29.662+08:00The term comes from photography, where transmissio...The term comes from photography, where transmission density of different glass was once measured through a strip of glass with progressively more opacity (simulating a wedge-shaped chunk of glass.) You would sample values through the "wedge" to get a range of results.<br /><br />The use then became more general, where a "wedge" of photographs would refer to a number of prints of different exposures, and later any collection of variants of an image used to select the best values of any given parameter.<br /><br />Today in CGI, we create "wedges" to explore the visual impact of changing any parameter, to determine the best compromise between look and rendering speed for example, or any other useful visual comparisons. <br /><br />Another fun term that's a holdover from photography is referring to a collection of reference images as a "morgue."<br /><br />Nice blog, cheers.Andy Mhttp://andy.moonbase.netnoreply@blogger.com
