Photographic Scale:
The three photos above were all taken from the same location and
direction. The photo on the left was taken with the zoom lens
set on wide angle. The picture on the right used the telephoto
setting of the zoom lens. The middle picture is between the
two, representing a sample from the field of view that would
be seen by the human eye. The photograph is, of course, just a small
rectangle in the larger view that a person would see, both as part
of peripheral vision and from the constant movement of the eyes and
head.
Nevertheless, the setting of the camera's lens has an effect
on the perception of scale within the context of the photograph.
In the left photo, the diminuition of apparent size in relation to
distance is exagerrated, and the expanse of street surface and sky
are large in relation to the total area of the photograph.
Because of these effects, wide angle settings used in photo
simulation can make the project appear smaller within the scene
depicted. The usefulness of such an image for visual impacts
assessment is questionable.
What can be done if the photo taken at "normal" focal length cannot
encompass a meaningful portion of the project? See the next
page for an explanation of "photo stitching".
