Hi Pat Thanks for suggestions, The first shot was just straight processing in Photoshop. This one I’ve gone round the houses with. I created 3 images in raw, put them into Photomatix but didn’t use tone mapping, which seems to amplify the noise? I used colour blending. Colour blending didn’t seem to have any effect on the noise. I did a bit of sharpening and colour work in Photoshop. I don’t know if it was worth all the fuss. I suppose it’s a learning curve.??? Mike
