How does the CMOS sensor work?
What does having a larger sensor do for the image?
An image sensor converts light information entering the lens into an image file that contains color, tone, shadow, and highlight. The light data determines the brightness and color of a pixel, and when combined, creates a digital image. A CMOS sensor uses multiple transistors for each pixel to transmit the light charge. A larger sensor delivers more signal that noise, giving it a greater signal to noise ratio. It also allows you to have shallower depth of field.
