>>3938008>Snr is measured per unit areaWrong, snr is measured based on your total output, ie total photo. This is basic electronics.
>Dr has nothing to do with pixel countCorrect, it's about how many values you can ascertain from your data. 10 values is twice as much as 5 values, and therefore double the DR, read my post again.
>Why do you think snr is area dependentBecause it is, Dr is just snr at max capacity, and look at camera sensors, double the size and you gain a stop of DR, one stop is a doubling\halfing of snr.
>>3938017Read his site again, if you're measuring by pixel, the total sensor size is irrelevant, if you're measuring by photo, sensor size is critical. Your lack of understanding is hilarious.
>>3938079Yes, you do get a brighter image, iso is an arbitrary figure to reach a reference value, in reality the gain applied per pixel is lower with larger pixels because larger pixels gather more light.
>>3938163Correct, iso is an arbitrary value to reach a reference brightness. Higher iso is just applying a higher voltage to a pixel, smaller pixels need more gain to reach the same brightness. Downsampling is just as effective as larger pixels too, hence total sensor size is all that matters.

>>3938238>Does your image get dimmer if you do an apsc size cropNo, but when you output at the same resolution as the full size sensor, your image quality (SNR & DR) will halve; which is the same level of degredation as going up an iso stop.
>>3938246If I put 5 pepperoni per slice on a pizza, and I have one pizza with 4 slices and another with 8, which one has more pepperoni? The level of pepperoni per unit area hasn't changed, but the area has, and the more slices, the more pepperoni.
