Now press the Density (Level) button.

The Chroma Key and Density buttons should both be illuminated red.

Again use the Adjustment Knob to eliminate as much backdrop as possible.

Before Density Adjustment-

Creases and areas of shadow can

be seen.

After Density Adjustment-

The Backdrop has now become

completely transparent.

Edge Adjustment (Shrink)

Once Density has been adjusted we should be getting a pretty good Chroma Key Effect. It is often worth

going back to the Green Keying Level Adjustment to fine tune after the density has been adjusted. If your

backdrop and subject are well lit you may not need to fine tune the result, however there will be occasions

when the subject still has a dark edge even when you have set the Green Keying and Density Levels

correctly. This is why the DVK-100 has Left and Right Edge Shrink Functions. If we look closely at the

subject in our example we can see there is an edge running along the left of the image (this is due to the

uneven lighting set up that we have used).

We can see in these images that a strong dark edge is running along the left edge of the subject. To correct

this we will use the Left Shrink Adjustment. If there is an edge on the right we would use the Right Shrink

Adjustment, the procedure is the same for either side.

Press and hold the Shrink Left button for two seconds, the button should flash red (if the red

LED is on constantly - i.e. not flashing - press and hold the button until it is flashing).
