Camera Manual Mode
I prefer using the camera manual mode for all of my photography because I feel that this gives the most creative control.
In Manual Mode, you as the photographer, have to make all the adjustments yourself.
In a lot of cases, you only really need to adjust the shutter and aperture and leave the camera to adjust ISO as necessary.
However, if you set your ISO parameters too wide, some of your “killer” shots may have too much noise.
If this is the situation, it is best to either adjust your ISO settings to a very narrow range. For example, adjust your ISO range from 100-400 ISO.
Or, you can turn off Auto ISO and instead change that manually for your photos.
