What really makes big sensors produce more appealing images? *Serious*

Re: What really makes big sensors produce more appealing images? *Serious*

I'm not sure there is a correct answer.

My guess is that it has to do with pixel size.

If a sensor is a light catcher that can only interact with a finite amount of photons before being full, then it only makes sense that more surface area represents a more accurate sample of light.

If light was made of M&M's of every color, pixels were buckets, and you were trying to catch a rainfall of M&M's that represented exactly the pattern they were falling in, the bigger you made each bucket, the larger sample you would collect. This gives the advantage to the bigger buckets.

Some will argue that a smaller bucket would still accurately reflect the pattern, but as with any gathering, the larger the cross section, the more accurate the results.

I poll 500 people on their beliefs and find that they are split 50/50. Then I poll 2000 (full frame is about 4 times the surface area of 4/3). I find that the split is 45/55.

Both collected samples are accurate, but one is a better representation of reality.

A full frame sensor interacts with more photons per exposure.

The details, colors, contrasts and gradiations are going to be more accurate by a factor of four.

This may only mean a 5% variation (like my fake poll) or maybe less than 5%.

Not enough to matter to some, but huge to others.
