Focal plane shutter
A shutter which lies just in front of the focal plane. Light sensitive film positioned at the focal plane is progressively exposed as the shutter blinds move across it.

Focal plane
The area behind the lens where light is gathered to form a sharply-focused image. It's here where the film or CCD is placed. An imaginary line perpendicular to the optical axis which passes through the focal point.

Techniques Glossary Focal plane

Focal plane shutter
One of the two main types of shutter and used universally in 35mm SLR cameras, positioned behind the lens and in fact slightly in front of the focal plane; the shutter consists of either cloth or metal blades.
Focal plane. The surface inside the camera on which a focused lens forms a sharp image.
Focal-plane shutter. A camera mechanism that admits light to expose film by opening a slit just in front of the film (focal) plane.
Focal Plane Shutter
A focal plane shutter exposes the image by moving two light-blocking curtains across the front of the image sensor.
Focal plane - position in the camera where the film is
Lens hood - shade to keep stray light from the lens surface [These are sometimes built into the lens, or they are removable. Lens hoods do more then protect the lens from light...
Focal plane
To describe it, we should imagine there is a plane perpendicular to the optical axis where the light ray is commonly passes through and form a sharp focus. It will form a plane of sharp focus when the lens is set at infinity.
FOCAL PLANE SHUTTER - A camera shutter situated directly in front of the film, composed of an opaque curtain that contains a slit that moves directly across in front of the film, permitting light to strike the film.
Focal plane. The plane - normally flat and at right angles to the lens axis - on which a sharp image is formed. In the camera, the emulsion surface of the film must be in the focal plane at the moment of exposure to record a focused image.
focal plane
a plane or surface on which a lens forms a correctly focused image.
focus
(1) point at which rays of light meet after being reflected or refracted; (2) adjustment of the distance setting on a lens to sharply define the subject.
FP (Focal Plane) flash Bulb
A special flashbulb that can be used at certain shutter speeds is called "FP" where the initials stand for Focal Plane.
[edit] Focal plane shutters
Almost all contemporary SLRs use a focal plane shutter located in front of the film plane, which prevents the light from reaching the film even if the lens is removed, ...
Focal plane (FP) flash seems to be a quite new technology but surprisingly the concept is already known for some decades (e.g. Olympus OM-3Ti, OM-4T) - see below. It allows faster sync. speeds than just e.g. 1/200s.
Focal plane shutters, found in all digital SLRs open one curtain to begin an exposure and close another curtain to end it (above, top). At high shutter speeds, there is a slit between the two curtains moving across the image sensor (above, bottom).
Focal plane
Imaginary line perpendicular to the optical axis which passes through the focal point. It forms the plane of sharp focus when the lens is set at infinity. (Also see focal length).

The FP (focal plane) sync feature allows flash photography at any shutter speed, including faster than the typical maximum sync speed at 1/250 second.
Thus, a lens labeled as an 8-inch lens indicates that when it is focused on a point at infinity, the distance from its optical center to the focal plane is 8 inches.
Parfocal Eyepieces with common focal planes so that they are interchangeable without refocusing. Parallax Generally speaking, parallax is the apparent shift in the direction to an object as seen from two different locations.
The latter has a flat image plane where the resolution is quite constant across the entire focal plane. The eye is not like that at all. It has a motion sensor that covers nearly 180 degrees of horizontal vision.
Depth of focus refers to the zone in front of and behind the focal plane in which the blurred image point is smaller than the acceptable circle of confusion.
Nikon's Auto FP mode (standing for Focal Plane) allows a flash to be used at shutter speeds faster than the camera's x-sync in order to freeze motion or use a larger aperture.
Helicon Focus is a Software product that lets you stack multiple exposures with different focal planes (or different areas that are in focus) to create a single image with increased DOF.
You can find it here.
High speed sync (also known as focal plane or FP mode) flash.
Synchronizing flash exposure with both curtains of focal plane shutters was as much of a problem in the days of single-use flash bulbs as it is today with electronic flash units.
Light is focused onto the focal plane (shown in green) to a small spot. The red lines represent a point that's further from the lens.
They take the place of a piece of film that must be moved across the focal plane of the camera. The digital sensor is made of millions of tiny sensor points called "pixels," which is short for "picture elements.
1 shows how the light from subject (A) reaches focal plane (A') through the lens. Without camera shake, light from A converges at A'.
Most SLR cameras use a focal plane shutter. This mechanism is very simple -- it basically consists of two "curtains" between the lens and the film. Before you take a picture, the first curtain is closed, so the film won't be exposed to light.
But in a digital SLR, a mirror placed in front of the focal plane (where the image sensor sits) bounces the light that comes from the lens upward into a prism and then out the eyepiece.
Optimum macro performance for the DSC-R1 was found at full telephoto with a subject distance of 35 cm from the focal plane (sensor) or 25 cm from the front lens element (this is the same as the Sony specified minimum focus distance).
The focal length of a lens is the distance, in millimeter, from the optical center of the lens to the focal plane when the lens is focused at Infinity. There are two important features to look for in a lens. The first thing is the angle of view.
2) Ensure that both faces are in the same focal plane as seen by your lens. If one person is slightly behind the other, you have to be sure that you position yourself so that they appear to the camera that they are standing equally side by side.
Every lens, to a greater or lesser extent, focuses the light of different wavelengths onto different focal planes and magnifies it differently.
To a greater or lesser extent, every lens focuses the light of different wavelengths onto different focal planes and magnifies it differently.
The degree to which the scene remains in acceptably or perceived sharp focus in front of and beyond the focal plane. A larger aperture number (i.e., f/16) produces a broader depth of field.
Focal Length The distance from the principal point to the focal point. Focal Plane The precise position (plane) within the camera body, behind the shutter curtain, at which the light gathering surface of the image sensor is fixed.
This is a camera function that bounces an invisible beam of light off the primary object or focal plane of the image you've composed in the camera.
Also known as color fringing, this problem is caused when the camera lens do not focus the different wavelengths of light onto the exact same focal plane.
#9 - Compose subjects parallel to the camera for close-up macro photography if possible, to get all of the subject in the focal plane.
#10 - Get the exposure right in camera; don't rely on post-processing.
Since strobes discharge in the range of 1/7,000th second, and cameras with focal plane shutters typically synchronize at no greater than 1/250th second, slaved strobes make sense.
f stop - an adjustment which changes the aperture of the lens (controlling the amount of light that reaches the focal plane) by adjusting the iris of the lens.
Purple Fringing - Also known as Chromatic Aberration. This is when the lens is not able to achieve focus of various colors in the focal plane resulting in a fringing effect around the other image.
When opened wide (smaller f-number) the zone of sharp focus can be very narrow. Portions of the image become progressively more blurry as they get farther away from the focal plane (plane of perfect focus). This works in both directions.

When you tilt the lens, you alter the focus point, so you may have to make some additional adjustments to focus and tilt until you find the optimal tilt angle and focus point. Once the proper focal plane is achieved, ...
In this diagram the focal plane is where your camera is and the focal length is how far away the subject is. Different lenses have different focal lengths meaning they have an easier or harder time focusing on objects at closer/farther distances.
