Water vapor is transparent, it is invisible, it will not act as a movie screen.
A water screen uses a spray of liquid water, which is not invisible.

Abstract:
The subject matter disclosed herein involves systems, methods, apparatuses or devices related to infrared imaging or infrared imaging projection.
Claims:
1. A method, comprising:illuminating a display with infrared radiation to at least partially obscure a displayed image otherwise viewable by an imaging device.
3. The method of claim 1, wherein said display comprises a display screen;and further comprising, prior to said illuminating said display, placing an overlay over at least a portion of said display screen, said overlay being at least partially reflective of infrared light.
[0005]It is becoming commonplace that at least one solid state imaging device is available to or is carried by each person that attends a venue, such as an entertainment complex, theme park, zoo, and museum. The proliferation of solid state imaging devices has impacted revenue generating services normally provided by the venue. For example, a museum may offer for sale photographs of artwork in the form of photo-books and postcards, but a visitor may be able to obtain high quality digital images of the same artwork using a solid state imaging device.
[0006]Another noteworthy example is the candid photo service offered at the point of exit of an attraction, especially such as those found at a theme park. It has become commonplace for theme parks to offer keepsake photos of the visitor experiencing, for example, a moment of high excitement on a thrill ride attraction. Upon exiting of the attraction, the visitor may be presented with a high definition display monitor displaying the candid image and an offer for sale of a photo of that image. It is becoming commonplace that instead of the visitor purchasing the candid photo, the visitor is simply capturing the image off of the display monitor using their solid state imaging device.

Some vapor clouds may be visible (LNG) and thus reflect light. Water vapor is not and does not.
Smoke is visible. Water vapor is not.
