Info Korsö torn (tower), Korsö island, Stockholm archipelago. Originally built as a lighthouse in the late 1700s, later used as a military observation tower. The images was taken from a chartered helicopter, as part of Wikimedia Sweden aerial photo project. Created, uploaded and nominated by -- Arild Vågen (talk) 12:02, 19 July 2014 (UTC)

Question Nice pic. Perhaps a little boring centered composition. Weird. When I look at the cliffs in the foreground they appear duplicated or motion blurred. In theory it could be because the vantage point was changing during the shot, while you were focusing on the tower, but I would be surprised if this happened with 1/1000 s exposure unless the helicopter was moving very fast? It could also just be because of the f/4.5 aperture and the associated low DOF. --Slaunger (talk) 12:15, 19 July 2014 (UTC)
- Slaunger: even a pro lens as the 24-70 has weakness. The border sharpness at long distances is the weakness here. DOF should not be a problem here, because of the distance to the object (at least 200 meters altitude above the sea, and some distance from the tower and the island). There is no downsampling and almost no crop here, normally you do not see 24mp aerial images. Here is a 3 mp version of the same photo, looks very sharp.--ArildV (talk) 13:43, 19 July 2014 (UTC)
- @ArildV: You are right. Thanks for explaining. As you know, I am often hit by the limits of my own mediocre lenses:) --Slaunger (talk) 13:55, 19 July 2014 (UTC)
