Focus at different apertures

7 Jul

This exercise is about having the camera on a tripod and taking a picture of the same scene at different apertures and then looking at the differences in depth of field (DOF).

First picture is at an aperture of 4, largest aperture on my lens. DOF is in the middle section of the bookshelf, focused on “gaedingar”-book. Depth is from about the first book to the black book about hov-diseases.

Aperture f4,0

 

Picture number two is with aperture 22, maximum on my lens. DOF is across the whole picture.

Aperture f 22

 

The third picture is at an aperture of 10. DOF is from the first book of the middle section to the wooden part between the middle and left section.

Aperture f 10

 

Conclusions: The smaller the aperture, the wider the DOF.
