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 :)
