As magnification increases, it becomes increasingly critical that you place your camera's film plane (essentially the back of your camera) parallel to the predominant plane of your subject.
Indicates the distance from the film plane to the subject, usually in both feet and meters.
FILM PLANE - The place in a camera where the film is located in readiness for it to be exposed to light.
FILM SOLARIZATION - See "Solarization" in this Glossary.
Film plane
The plane on which the film lies in a camera. The camera lens is designed to bring images into focus precisely at the film plane in a camera to ensure correctly exposed pictures.
With flat film planes a pinhole has a usable circular image of approx. 125 degrees. The image diameter is about 3 1/2 times of any focal length. The image will fade towards the edges because of the increasing focal distance.
With a flat film plane, 90° is about the widest field of view that can be captured with normal sharpness and without significant wide-angle distortion or light fall off by a traditional lens and camera using a single, flat piece of film.
The variable opening produced by the iris-diaphragm through which light passes to the film plane. Measured in f/stops.

The term illuminance means the amount of light reaching the film plane. By adjusting these controls, you allow the correct amount of light to reach the film. The correct amount of light varies, depending on the film speed.
If you are considering a long focal length lens that is not a telephoto design, be sure to measure your camera's actual maximum film plane to lens board bellows extension. Don't trust the manufacturer's stated bellows extension.
For example, the back focus distance (distance from the rearmost lens element to the film plane) on EOS cameras is 44mm, but on Leica rangefinder cameras it's 27.8mm.
Special lenses called shift lenses can move the front element relatively to the film plane thus keeping verticals straight. However failing this you could look for a viewpoint higher up so that you don't have to tilt the camera backwards.
In conjunction with this is how perpendicular the subject is to the film plane. Subjects that are parallel to the film plane provide more depth of field than those that fall perpendicular. Just as important is the aperture at which the photo is made.
To understand how, imagine the part of the studio setup on which you focus as a flat plane, much like a pane of glass, superimposed from one side of the setup to the other, so that the plane is parallel to the camera's film plane.
Focal length - distance from the optical center of a lens to the film plane [In layman's terms, this is how long your lens is.
The distance between the film plane and the focal point (optical centre of the lens) when the lens is focused at infinity. The focal length of the lens is marked in millimetres on the lens mount.
If your plane of focus is not parallel to the film plane you might have difficulty bringing everything into sharp focus. Large format cameras allow you to alter the plane of focus and move it instead of having it parallel to the film plane.
" Usually this image is located at a distance of about twice the diameter of the dome from the film plane: a six-inch dome will have a virtual image 12 inches from the film plane; a nine-inch dome at about 18 inches, etc.
Displacement: Camera displacements are a feature of Large Format studio cameras that allow the relationship between the film plane and the lens plane to be altered in order to alter and control the perspective of the image.
While other cameras are designed with the film plane and lens plane parallel, the view camera allows independent movement of both.
Secondly, the primary lens can be moved further from the film plane by inserting a so‑called 'extension tube', which extends the distance between the lens and film plane and thus allows the lens to be brought very much closer to the subject.
For a simple 50mm lens, if you put it 100mm from the sensor/film plane, it will give a 1x magnified image of an object that's 100mm from the lens. However there's a catch.
The distance from an internal part of a lens (the rear nodal plane) to the film plane when the lens is focused on infinity.
Parallax Effect This occurs when a camera utilizes one lens for the viewfinder and another in which light travels through to reach the film plane or image sensor.
Focal length is the distance between the focal point of a lens and the film plane when the lens is focused at infinity. It is used to designate the relative size and angle of view of a lens, expressed in millimeters (mm).
A lens fault which results in degraded image quality at the film plane. It is caused by light rays passing through the lens from a single point on the optical axis focused at different points according to incident height.
The distance range over which the film could be shifted at the film plane inside the camera and still have the subject appear in sharp focus; often misused to mean depth of field. Also see "depth of field" section.

Condenser Enlarger: An enlarger using one or more glass condenser lenses between the lamp and film plane to provide a focused and even distribution of light.
The adjustable opening, or f-stop of a lens, determines how much light passes through the lens as it travels to the film plane, or surface of the camera's imaging sensor.
Bellows - light tight, folding sleeve which can be fitted between the lens and the film plane.
Bellows shutter - obsolete shutter consisting of a pair of bellows that, when closed together, form a hemisphere enclosing the lens.

Camera movements
Mechanical systems most general on large format cameras, which offer the ability for lens and film plane movement from a typical standard position.

â†' More properly, this should be called "close up" rather than "macro"; the definition of "macro" is that the "image projected on the "film plane" [...] is close to the same size as the subject", which it isn't on small-sensored digital cameras.
"Not only does this design yield an attractive camera but it is extremely accurate. The lens and film planes have a parallel accuracy within the fractions of a millimeter. The designs have no perspective-controlling movements.
The classical definition is that the image projected on the "film plane" (i.e., film or a digital sensor) is close to the same size as the subject. Here are photo tutor that explains the various types of equipment you can use to take macro photos.
The Lens is the camera element that is constructed of multiple pieces of glass to focus light to a given focal point, which is usually the film plane or image sensor.

The flash fires an instant after the front curtain (first curtain) of a focal plane shutter has completed its travel across the film plane. This is the way the camera operates with the flash sync mode at Normal Sync.
swing lens camera noun
a type of panoramic camera in which the lens rotates from side to side, painting the image through a slit onto a curved film plane and producing a cylindrical projection ...
Image plane
The area inside the camera where the object is focused clearly. The image plane can be compared to the film plane in analogue cameras; the difference being that the film is replaced by the CCD chip.
The distance betwwen the near nodal point of the lens and the film plane when the lens is focused on infinity.
F-stop
The ratio of the lens focal length divided by the apparent aperture of the lens. The larger the aperture, the smaller the f-stop.
They fit between the lens and the camera body and, as the name suggests, there is no glass in them, they merely serve to move the lens further away from the film plane (or CCD on a digital camera).
is also given perspective if there are objects in the foreground, middle distance and background, giving the whole scene “depth". For most photographers perspective refers to the relationship of the subject to the camera sensor or film plane.
In contrast to the other focusing systems there's no need to shift heavy groups of glass but the film plane in the camera itself is moved for focusing. The shifting distance is relatively small so the focusing speed is potentially fast.
