| 17:29, 11 January 2021 | Sharp london.jpg (file) |  |
432 KB | Kgf | Picture of London taken with a Nikon 105 mounted on a Nikon D810. The picture highlights various issues on sharpness. The roof at the bottom is too close and out of focus, there are various chimneys that release smoke which ''blurs'' part of the image, and there is a haze that limits the visibility to the distance. However the small cutout File:Sharp_london_zoom.jpg shows that even on the side this picture is actually remarkably sharp. | 1 |

62 KB | Kgf | Airplane taking off at Zurich Airport, Switzerland, captured with Nikon 200-500 with exposure time <kbd>1/200s</kbd>. When compared to File:Takeoff 1000.jpg you see that the propellers are ''blurred'' showing that the plane is in motion. The trick is to keep the rest of the image sharp, since we are using very long focal length for airplane pictures. Fortunately, the propellers rotate quite fast, and the plane has a very predictable trajectory, helping us. | 1 |
