Hi all,


I have the 7D and have realized that a few of its images at low ISOs have large amounts of "noise". This example taken at ISO 400:


[img]/resized-image.ashx/__size/800x600/__key/CommunityServer.Components.UserFiles/00.00.00.36.40/IMG_5F00_2703.jpg[/img]


Here's a crop in which the noise is pretty visible:


[img]/resized-image.ashx/__size/1000x1800/__key/CommunityServer.Components.UserFiles/00.00.00.36.40/crop.jpg[/img]


What can be done about this in-camera? I don't have PS. Is this indeed the "green stuff/noise at low ISO because of the mirror" phenomenon?
