2-2 Adjusting the Lighting
Specimens of different size, thickness and color variations will require different levels of
illumination. There are two ways to change the amount of illumination when viewing a
specimen:
1. Adjust the brightness dial shown below in Figure 2.2. (label the dial)
2. Change the EV setting on the LCD monitor. The EV (exposure value for
brightness) function increases or decreases the brightness level by using the “left”
or “right” arrow keys on the LCD monitor
When viewing a specimen that is not transparent or dark in color, you may need to increase
the amount of light to see certain features and details vise versa if viewing a more
transparent lighter object. Optimum lighting will be found by experimenting with different
light adjustments for each specimen.
