Question

how does noise effect the performance of a digital camera?

Answer 1

Hi, McLovin



Noise is apparent by the presence of color speckles where there should be none. For example, instead of a blue sky, you notice faint pink, purple and other color speckles amongst the otherwise blue sky.



This usually occurs when using high ISOs and long exposure times. So a better noise performing camera can produce better quality pictures under low light condition.

The "Noise" you see in digital images varies depending on how sensitive the "digital film" is to light. in very low light situations you can change the camera's "ISO" to a higher number to compensate for the low light, this generally ends up producing more "noise." wiht a high ISO the camera's CCD (the digital film) requires more enegry to be more sensitive to the light... with the extra electricity being used the CCD not only captured the visual light information but also some distortion from the extra electromagnetic charge. in pictures this leads to a grainy look up close and less accurate colors. some high end digital cameras have noise reduction built in to minimize this effect, some don't. generally the "rule" is to shoot with the lowest ISO you can to avoid as much noise as possible, but sometimes the grainy look is cool so i will intentionally crack the ISO up all the way to get as much noise as i can in shot.

Answer 3

It doesn't affect the "performance" of a digital camera but it can degrade the aesthetic appeal of an image. Noise can ruin fine details and it is especially annoying in simple expansive areas of your image such as the sky and walls, etc.



Always use the lowest ISO that you feasibly can while keeping your image sharp and that will help. Another way to help control noise is to use hardware with the biggest sensor you can afford. Less pixel density generally mean less noise.

Answer 4

I'm going to assume you're referring to visual noise. Noise means your pictures will appear grainy.
