I took this picture of downtown Tampa to practice my focusing. I think is pretty good, but not sure if it is completely sharp. I focus on the left side of the bridge, using the double distance focusing technique. Nikon 18-55 mm, ISO 100, 20 sec, f/8 27mm.

Armando Pinon, the focus is slightly off, however, this is about the hardest subject to get any better. Personally I like the photo and would frame it on a wall. I used a DDL to see the sharpness.

Hi, thanks for your comment. Double Distance Focus basically you find the closest element in your photo estimate how far it is (camera sensor to that element ), double that distance and focus there. That should give you equal foreground and background sharpness. IE: If your closest element in your photo is two meters away the hyperfocal distance is 4 meters away. See link below for more details.

Armando Pinon, DDL stands for a double down load.
