Exercise – Focal Length and Angle of View

Requirement:

This exercise required three photographs taken at differing focal lengths, the first a near life like, the second with the camera at is shortest focal length, and the final image wit the camera set to its longest focal length.  For this exercise the camera was set to automatic and only the focal length was changed.

Chimonanthus praecox (Winter Sweet)

Chimonanthus praecox (Winter Sweet)

Starting with an image of the Chimonanthus praecox (Winter Sweet) that grows outside of the house, this was taken with the view through the viewfinder looking the same to that seen by the unaided eye.

Much of the detail and interest of the primary object of the picture, the shrub, is lost, due to the inclusion of the background.

The result is what comes across as a messy image.

A second shot was taken, with the lens set to its widest setting, this time at 18mm.  Compared to the previous image that overall picture seems much better inasmuch at least the entire shrub is visible.  The initial photograph did not show all of the plant, this image allows the viewer to see the overall plant in respect to its surroundings, giving a better understanding of the plant, but still lacks impact.

The aim of JSPS RONPAKU (Dissertation PhD) Program is to provide tutorial and financial support for promising researchers in Asia and Africa who wish to custom writing dissertation
