7. Camera Exposure Profiling

1. Calibration testing for exposure profiling

A camera exposure profile plays two main roles.

[1] It can be used to display on a light meter the unique dynamic range and clipping point of the

digital camera you are using.

[2] To display more accurate exposure values on the light meter, it records unique variations in the

camera, lens shutter speed, aperture, etc. that you are using and reflects them in the exposure

display.

The L-758DR/L-758D/L-758CINE can be programmed to stored, recall and display up to three dif-

ferent digital cameras.

Below are the following settings that can be programmed into the L-758DR/L-758D/L-758CINE.

1. Compensation value

Compensation value (aperture and shutter speed) can be programmed for a specific camera

and hand-held meter. Compensation adjustment is within a +/- 5EV range in 1/10 step incre-

ments.

2. Dynamic range (-)

The point at which a given lighting situation (pre-exposure) has surpassed the responds level of

a sensor and alerts the shooter of a under exposure situation (Pre-Exposure Warning). These

point can be custom set from -7EV to 0EV in 1/10 increments.

3. Clipping point (-)

The point at which the sensor has reached its maximum reproducible shadow details without

pixel noise or grain. Dynamic range (-) adjustment is set from -7EV to 0EV in 1/10 step incre-

ments.

4. Clipping point (+)

The point at which the sensor has reached its maximum reproducible highlight details without

blooming or highlight block up. Dynamic range (+) adjustment is set from 0EV to +7EV in 1/10

step increments.

5. Dynamic range (+)

The point at which a given lighting situation (pre-exposure) has surpassed the responds level of

a sensor and alerts the shooter of an over exposure situation (Pre-Exposure Warning). These

point can be custom set from 0EV to +7EV in 1/10 increments.
