21. With his principal cameraman Georges Lucas, L'Herbier created a number of optical effects during filming. 22. Such an observer will experience some interesting optical effects . 23. This representation also predicts optical effects that are purely quantum, and cannot be explained classically. 24. Milius eschewed optical effects , preferring to realize his ideas with mechanical constructs and optical illusions. 25. In further development, Molinari began to focus on the geometrical optical effects and changing perspectives. 26. An optical effect might be used to place actors or sets against a different background. 27. Logic gates can be made from non-linear optical effects . 28. There are subtle optical effects that you can feel but can't quite put your finger on. 29. As this would have required subcontracting the optical effects , Republic saved money by not using it. 30. Joshi has made many fundamental contributions to the understanding of extremely nonlinear optical effects in plasmas.
