1. As already mentioned dynamic range is the range between the brightest and darkest values that a camera can record. A wider dynamic range means that you gain a better gradation from light to dark.So here's my question or questions.
1. What is dynamic range?
2. How does it impact on a photograph?
3. Does it effect more in certain styles of photography?
4. Why are some cameras/sensors better than others, even from model to model?
Your eyes do have a dynamic range… and a more extended one than any chip atSo here's my question or questions.
1. What is dynamic range?
If poorly metered the exposure may be too high for the chip, like blinding it. If the2. How does it impact on a photograph?
I don't think so. A good exposure or a bad one will render good RAW data on bad3. Does it effect more in certain styles of photography?
There are indeed different qualities of sensors, and different prices as well. Certain4. Why are some cameras/sensors better than others, even from model to model?
•It would have taken hours to type that lot.
I think the difference with the human eye is that you are generally only looking at one part of the scene at a time but a camera has to take in the whole scene at once.
Just done a bit of research on this and according to Cambridge in Colour the DR of the human eye isn't any more than the best cameras but because we instinctively focus on different parts of the scene the eyes adjust without us noticing and so we get a perceived much bigger DR. Contradicts what I've read before but there you goI think the difference with the human eye is that you are generally only looking at one part of the scene at a time but a camera has to take in the whole scene at once.

Well I have read other sources The consensus is the DR of the human eye is 10-14 stops.•
Please, don't stop there… seek other source!
My analogy to the eye is one equation. Now the eye vs the camera is
another equation.

Lol, I just quoted them because they explained why we perceive the eye as having a greater range, but it does read as though that's the only source I read doesn't it•
Sorry, I trust you did! ;-)

What's that mean in English?Nope. That may be the instantaneous DR without adaptation, but the scotopic and photopic range is over 40 stops.
The eye can detect light over a huge range using different adaptation states. Far more than the 14 stops you mentioned.What's that mean in English?
Thanks. Yeah, that's what I said (or hoped I'd said) the eye adapts so DR is much wider, but without the ability to adapt the DR is no better than a camera.The eye can detect light over a huge range using different adaptation states. Far more than the 14 stops you mentioned.
From ~10^-6 to ~10^8 cd/m^2.
