http://www.lightstalkers.org/posts/schwarzschild-by-digital-sensors An entire Lightstalkers thread via RSS/XML. en-us I was woundering if any of you know if a digital sensor under the influence is of the Schwarzschildeffect. An other word for it is the Reciprociteitsdeviation.

Wed, 14 May 2008 23:22:29 +0000 http://www.lightstalkers.org/posts/schwarzschild-by-digital-sensors#121376 I had to make a report on sensitometry and I started to think if it was also with a digital sensor but I understand why not. Atleast I think I do. The lightsensitive component of the film has to be exposed for a certain duration with a certain intensity. But if the duration is to long with a low intensity, light that has allready reached the lightsensitive components, doesn't influence those components. Therefor you have to expose them extra long with a low intensity to compensate that loss of light. But a sensor isn't made of that same lightsensitive components, is it? It's made of something that records every moment of low lightintensity and therefor there is no lightloss. Am I correct? Now I wanna know what a sensor is made of so I 'm gonna surf the web a little bit :) Thu, 15 May 2008 15:22:40 +0000 http://www.lightstalkers.org/posts/schwarzschild-by-digital-sensors#121439 a digital sensor is basicaly a CCD see: http://en.wikipedia.org/wiki/Charge-coupled_device Fri, 16 May 2008 11:52:23 +0000 http://www.lightstalkers.org/posts/schwarzschild-by-digital-sensors#121477 indeed I went there and I learned a lot I allready knew but forgot again :). But how do they know that a sensor they make has an ISO = 100? Who makes those CCD's or CMOS's? How do they determine or make a ccd of 100 iso?
