Here is one from this morning. A crop also from the image, all converted in Aperture, no noise reduction applied other than Apertures default + some edge sharpening.
This was not the job, but Terminal 5 at Heathrow looked good so I took a few, thinking BAA's picture library might be interested, but no they didn't even want to look. Alamy here it comes then.
iso 1250 f9 1/640th 17-40mm @ 22mm.
Yes you can see noise in places but nothing to get excited about.
