I just had a look and couldn't see any sign of noise either .

I put that picture of the boat in dry dock into Topaz Adjust. Lots of detail pulled out of the shadow area, but next to no noise.

Nope. I don't see any appreciable noise either.
Is it possible that we are at crossed purposes. Are you seeing something that you mistakenly believe to be 'Noise'?
Try to describe what you think is wrong and we'll pick it up from there.

I can only see that spot on the left side, half way up, about 15% in......... and that's dust on the sensor. That's on the one with HMS Dragon (not the dry dock one) purely because it's in front of a blank or single tone area. S'not noise.

hi everyone

thanks everyone for your replies, very much appreciated
Chris I think i was seeing pixals when I had picture in photoshop at 100%.
How do I get rid of dust mark on sensor, can i clean myself or is it a job for a photography shop.

It will look noisy zoomed in. You can just try blowing some air in the camera but NOT compressed air from a can, that could damage it. It may come off. I would recommend a professional clean if that does not work.

Yes, when the image is viewed at 100% you will see some pixelation. Try to imagine what size the picture will be if printed at 100% - it will be pretty big. Consequently, under normal conditions it will be viewed from some distance where the pixelation will not be apparent. While you're looking at it on the screen you'll be much closer than normal viewing distance.
We recommend carrying out tasks such as sharpening etc. at 100% to avoid over-sharpening and the like, but normal viewing of the whole image on your PC is likely to be around 25% at most.

it may be on the sensor or even the lens

I think it would have to be on the sensor to show up like that. Unless you're skilled and experienced, I would leave cleaning the sensor to a specialist. Sensors are very easily damaged and very costly to replace.
