A CYC wall is a backdrop that is often used for theater and photographic effects. The use of a cyclorama allows for control of the background so that you can simulate a range of effects. Some like to work with colors and patterns while others like to work with a background that appears infinite.
If the backdrop is painted white, then it can be used to take photos that have no background. Green screen CYC is utilized to mask the background and provide an illusion. Building a cyclorama will usually mean building a curving screen with no visible seams. Different materials can be used for construction like wood or fiber glass.
A simple construction will mean first choosing what size the structure should be. Plywood is then attached to the walls and the floor using construction adhesive. These are secured with drywall screws. Then curved plywood triangles are created to fill in the curved area of the backdrop.
Mesh lath is then applied to the curved site. Then, fiberglass is used to coat the structure twice. Then four coatings of drywall compound are applied. Each coat is permitted to dry and is smoothed with by sanding. Primer is then used to coat the surface before the white paint is applied to the background.
Green screen CYCs also use a similar design. The paint however will be green and a specific type is needed to make sure that its reflective properties are compatible for use. Paint is essential in making the subject look natural against the background. Considerations for space should also be factored in since the dimensions determine the amount of motion that can occur. Lighting should also be even to maximize effects.
These backgrounds can be utilized in various applications. The fashion industry for example uses a cyclorama as a tool for creativity. Movie and television sets also use these backdrops to create a considerable amount of effects. Studio CYC are utilized by in auto and custom photography to take photos.
Using a cyclorama will mean having complete control over the lighting. Therefore sunlight and other kinds of illumination other than your own should be eliminated. The subject and the light source should then be positioned accordingly.
By using lights and positioning them at certain angles so that they hit the CYC wall evenly, you will get no shadows and the background gains the infinity effect. If you want the background to be dark, you use no lighting at all except on the subject. Shades and silhouettes can also be controlled by repositioning the light source.
