With my over 20 years experience of Virtual Studio production I am in a perfect position to guide you through it.
Consulting on integration of Ultimatte to get full advantage from the unit.
Techniques for displaying hidden graphics in eyeline of presenters.
Use of Holdout matte to extend the use of real sets in Foreground and Layer matte to add another graphics layer to the composite.
Use of non CGI graphics backgrounds to give more realistic style virtual environments.
Chroma Key systems use the hue and saturation of the backing to derive the key signal.
Current systems both software and hardware use colour difference signals, compareing the levels of the RGB signals to derive the key signal.
Blue was preferred for colour difference keying as it does not appear in flesh tones and flare is less of an issue.With the emphasise on sports and news where suits predominate green has become the dominant colour although it has more issues with flare.
To enhance the feeling of depth in the final image you need to give the foreground a shadow. The safest direction for it is towards camera this avoids the possibility of the shadow running up the backing. The shadow needs enough density to give a convincing look to the final composite.
Rear backlight from both sides gives exposure in the sides of the Foreground to prevent a 2D cut out look.
Minimising depth of field will help with keying issues.
Purpose of the training is to make the operator familiar and comfortable with the system and its capabilities, to the point where they can achieve the desired results quickly and using the minimum controls.
The results achieved are a combination of the keying area, lighting and the Ultimatte itself. Carrying out training in the clients studio is essential.The session covers the number and function of external keys.
Processing colour correction ambience etc. to complete the believabilityof the final composite.

Recognition when the best results have been achieved with the keyer being used.
With my experience of all types of production that include Virtual elements I am in a perfect position to quide you through the shooting day.
Shooting Greenscreen or Virtual Studio has specific demands.
To allow a good flow to the studio day it is desirable to set up the studio in anticipation of the issues that may occur during the day, to prevent delays later.
Monitoring condition of backing and floor to maintain keying integrity.
