OK, a week ago I went by the beach, it was cloudy and rainy so I could not get much light. I was using my 7D in Aperture mode with Automatic WB and ISO. No matter what I set my Aperture to I would have an ISO of 3200. Tried using Shutter Speed mode with the same results. Adjusted the exposure settings a bit but still did not help. All my photos came out VERY noisy. I know I generally get good pics if I can stay under 800 ISO with my 7D, but in these circumstances the only way I could get enough light for an image was at 3200.

Any suggestions on how to capture an image with these conditions at a lower ISO? These were all the tricks I know of and I tried them all.
