<span style="color: black; font-family: 'Verdana','sans-serif';"]<span style="font-size: small;"]Noise reduction processes / options make the details of an image soft, so using them is not the best option.<span style="mso-spacerun: yes;"] I find that anything over ISO 400 starts to give noticeable noise in the shadows.<o></o>
