Picture Composition for Film and Television her, which he does not know anything - not the height of the lens or its angle or distance from the camera to the subject.The first thing to figure out - is the height of the lens, which made shooting background, then you can correctly set the height of the camera front-end. If the camera, removes the background, was installed without any slope, the horizon line will divide the frame into two.The most accurate measure of the height of the lens - the level at which the line crosses the horizon, the subject, the height of which is known, usually a human figure. If we can find any object standard height - mailbox, farm gates, table, etc.- And we can determine where in the horizon line intersects with this object, this point will determine the height of the camera background. If the horizon is in the middle frame and crosses the figure in the background at the level of the eye, the camera front-end should be set at the same level.If the horizon crosses the figure at knee level, you will need to install the camera foreground at this altitude. If the horizon in the picture are not visible, the horizon can be download the film Fix
and determined by projecting the horizontal lines stretching into the distance into the frame and finding the point where they intersect.If a block is not orthogonal lines, with parallel, which do not form a frame, for example a brick wall, you can define a horizontal line, which indicates the horizon. Viewfinders most studio cameras equipped mobile cursor, which can be used to find orthogonal lines on the horizon.If the camera background was tilted up or down, the camera operator from the front-end will need a detective job. If the horizon line at the top of the frame, the camera background was download the film Fix
and tilted down. If it is in the bottom half of the frame, the camera kept shooting when tilted up.Another indicator of the slope is the connection of vertical lines. Orthogonal lines are connected at the point of extinction, just behave vertical parallel lines, if you look at them the wrong angle.The point of their connection Figure 6 If we can find any object standard height - mailbox, farm gates, table - and can determine where in the horizon line intersects with this object, this point will determine the height of the camera background. Ward. Compose the shot, in the movies and on television is above or below the frame.The slope of the chamber background can be determined from the degree of taper toe vertical lines, such as the walls of buildings. But the deviation from the vertical lines also affects the distance between the camera and the lines. List the signs of linear perspective to the image when the camera is unknown slope and height of the lens:The height of the lens corresponds to the vanishing point of any horizontal line stretching into the distance.

. When the frame is visible horizon, the plan for the ground level and it splits the frame in half, then remove the camera running even.
