8.1.3 “Exposure” Section
“
Exposure
” section controls the exposure time and the brightness of the camera.
The camera can work in automatic exposure.
By activating the “
AE
” function, the camera works completely automatically. In this case it is not possible to act
on the parameters of the camera, therefore in situations of insufficient lighting it is possible that the camera can
not provide optimal image quality.
By activating the “
ME
” the camera works manually. It is therefore necessary to act on the camera parameters to
adapt the exposure time to the lighting condition of the sample.
Moving the slider relative to “
Bright
” increases or decreases the exposure time of the camera. Depending on
the amount of light that is used to illuminate the sample under examination, you will have to move to the right
(increase) or to the left (decrease) the cursor to get a perfectly lit image avoiding under or overexposure.
The cursor relative to the “
Gain
” commands the so-called “gain” of the camera. The gain is a function that allows
you to increase the sensitivity of the camera for shooting in low light. This obviously increases the background
noise.
