Kyle Geerkens Posted February 9, 2005 Share Posted February 9, 2005 I was recently asked to DP for a small shoot in Toronto. Very basic, they were an inexperienced bunch who wanted some "expert" (student) advice. They shot on the xL1s, and I noticed that the agin settings are massive! how much noise am I looking at as i increase the gain. I noticed theres a very noticeable difference bewteen the highest setting and the next whihc is a whopping +18db. Are these settings relative to other camera's or does a +6Db on the xl1's equal a different amount of gain on other cams? Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted February 9, 2005 Premium Member Share Posted February 9, 2005 (edited) Hi, 6dB is a given amount of gain over "normal", which is where the problem comes in, because different cameras have different ideas of what "normal" is. Different cameras also have different CCD assemblies and front-end electronics, which could affect noise figures at any level of gain - and the difference will be more pronounced at higher gain settings. Even changes in temperature may have an effect, as warm CCDs are noisier (Neener, LA people!) So in essence, 6dB is 6dB (twice as much) - but the effect that will have is situation-dependent.
