Is there amy relationship between aperture and noise. I shot some low light f/11 1000 ISO shots on my 5D which I think are noisier than normal.
Is there any correlation between a smaller aperture and noisier images?

Basically no. Noise increases with higher ISO. Really small apertures (like F32 on a DSLR lens) may cause difraction (some loss of IQ) but that is about it.

Not directly, but as apertures get smaller, and shutter times faster, higher ISO values are required. Higher ISO results in more noise.

Correct exposure (at any ISO) is the best hedge against noise.


When did voluptuous become voluminous?
