Looking for ways to keep the noise down when shooting with high ISO.
I have Noise Ninja, but to me its a tool of nessesity, and would like to only use that step if needed.
Is noise a heat thing? If so, beside turnig off the camera, and the monitor, how else can I reduce heat?
I can't reduce my f stop to a 2.0 when at 500 iso, so I have to increase the iso to get out of the dark.
Suggestions are welcome. Links are welcome. Threads are welcome.
Thanks in advance.

It's more of a function of exposure and sensor 'sensivity'. Since you are shooting at high iso to start with, try to avoid underexposing the photo with a negative EV. When you look at the high iso image and notice where your stronger noise is, you will find it in the lows usually.

So if say I am reading a 5.6f with a 1800 iso, expose to a 4.8f? or lower?

I'm assuming a typo and you are shooting at iso 800. If you are shooting at iso 800 and f/5.6, your best bet would be to shoot at iso 400 @ f/4.0 instead. That would give you the same shutter speed at a lower noise ratio.

heres the situation from the other night.
No flash first of all. My digital Sekonic was set reading 500 iso, the light was fading fast and read 4.8f.
Adjusting my camera, I increased the iso until I got a reading of 5.0f, iso 1600, shutter at 250. I turned off the review mode. Kept the camera off only until used. Shot what I needed.
Got home, edited, noticed some reduction in noise, but not alot.
With this in mind, is there more that I can do to reduce the noise without further increaseing the iso. I can't open up any further, 5.6f is the lowest it will go unless I adjust the shutter, then I will be dealing with blur, or darkeness again.
Thanks.

Are you looking for a cheap solution, or any solution?
There are f2.8 zooms, and primes are even wider. The EOS-5D may have better low-light performance than your camera because it uses newer technology.
You've probably already done the low cost things, like taking the UV filter off (if you use one). |

Try overexposing the image a bit by checking with the camera's histogram. Expose so the histogram shifts as far to the right as possible without clipping the highlights and blowing out the whites. This will minimize the dark, noise containing areas and then you can adjust your exposure back to what you desire in your editing software.

Do you shoot in raw? RSE have a very interesting option for nise reduction and it is not so effective as noise ninja but it is enough for keeping it down. I usually use it at 50% and it doesnt get the image as soft as Noise Ninja or others like it. It's almost has if you used a step down in iso. For example if you shoot 800 iso it will be like 400.
