Commercial Photography Assignment 2:
Basic Exposure
Equipment:
Camera, tripod
Formal Assignment:
The Basic Exposure Constant
(BEC), is an exposure calculation system based on analyzing the sun and shadow
conditions. It is a method for measuring light without an electronic meter.
Shoot outside during daylight
hours as this system is less reliable at dawn or sunset.
Using a tripod, compose
interesting images in 4 different lighting conditions (see BEC hand out for
categories).
For each of the four lighting conditions, make four exposures in the following
order…
1.
Using the
starting BEC settings
2.
Equivalent
exposure #1 (1-stop wider aperture with 1-stop faster shutter)
3.
Equivalent
exposure #2 (1-stop smaller aperture with 1 stop slower shutter)
4.
According to your
camera meter
[total
of 16 images]
Record the exposure info on
the accompanying Exposure Tracking Sheet.
Remember to use a tripod so
that the camera remains stationary for each group of photos. Framing should be
identical for each series.
To use the BEC effectively
remember to:
1. Select an appropriate ISO
to the brightness of the lighting condition, then keep the same ISO throughout
the entire suite of 4 images. You may change ISO’s for each of the various
lighting conditions.’
2. Set the shutter speed to
be the reciprocal of the ISO.
3. Select the f/stop based on
the lighting as described on the BEC chart.
Submit…
16-Jpeg images representing 4
different lighting situations. Select these 16 images and place on your blog.
