# exposure – Does Manual iso = low noise?

I was taking some test shots today indoors (decent amount of light) set the iso manually to 800 looked through the viewfinder and I was at 1/20 (I was using Av mode) bumped the iso to like 1000 and my shutter speed was like 1/80 i took the shot and I had a decent picture.

Question is does manually setting the iso vs auto iso (with a minimum and maximum iso) produce low noise?

Example: if i manually set my iso in AV mode will i get low noise instead of auto iso with a capped iso will I also get low noise? or are they totally different?

I asked this question here

Using Auto ISO when shooting

Looked at the answers but they didn’t specifically ask or talk about settings the iso manually will lead to less noise or no noise at all
