As you can see the image quality isnt great… However, this image was very clear on the camera, even when fully enlarged. Although, there is a lot of noise.

How can noise be reduced / avoided?

If you suggest a mode or setting to put it on, ill try that and upload another photo to show you.. It does 100% lose quality. Well, if its just my screen resolution, you can tell me that as it wont be blurred on your screen. However, it isnt blurred, nor is there any problems on my camera’s digital display

Firstly as a few people have said the shot is at ISO 3200. This is quite high but the 550d can manage it quite well. The shot you posted is huge so its hard to tell exactly tell what it looks like at a reasonable size that you may expect to print at.

It seems also to be slightly underexposed. This will add noise to a photo as much or more than increasing the iso. You can select noise reduction in camera, or if you post process a raw file you can do the reduction yourself. pixel peeping can also be a problem, if you zoom right in the photo will show defects not normally seen by the eye.

The camera screen does not zoom into the photo as much as a computer so it seems better there.

I don’t think your camera is at fault, you could have taken this photo at ISO 1600 with a shutter of 1/300th second and come out with the same exposure with less noise, but you will find if you practice a bit with processing things will improve.

Search this for techniques on exposing to the right for good noise reduction info
