Schwarzschild by digital sensors

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.

nope, no digital sensor suffers from that effect

may i ask why you are asking?

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 :)

a digital sensor is basicaly a CCD

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?
