100% size clip processed from Alpha 900 ISO 6400 RAW (uncompressed) using Adobe Camera Raw 5.3 release, with default sharpening (25) and NR settings of 50 chroma, 50 luminance. Shot using the Sigma 50mm f/1.4 HSM lens by street lights. The pub wall and the tarmac both have a texture, that's not noise - check the sides of the two planters for a plainer surface. The pub sign is black. It is possible to use up to 75 luma, 100 chroma NR and also to use no sharpening, to get an even lower noise result but there is some loss of colour.
