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.
