Photography  Parabolic mirror  Parallax error

Parallax is an effect in photography where the image seen in the viewfinder is not framed the same as the image seen through the lens, because the viewfinder is in a slightly different position to the lens.



The variation in viewpoint of a camera's optical viewfinder and that of the taking lens. This increases as you go closer to the subject.

Techniques Glossary
The variation in viewpoint of a camera's optical viewfinder and that of the taking lens. This increases as you go closer to the subject.

Parallax
Parallax is the effect of looking through a viewfinder that is distinct from the camera lens itself. Most point & shoots have you look through a small opening that is an inch or two away from the actual lens.


With a lens-shutter camera, is the difference between what the viewfinder sees and what the camera records, especially at close distances. This is caused by the separation between the viewfinder and the picture-taking lens.

Parallax
The difference in point of view that occurs when the lens (or other device) through which the eye views a scene is separate from the lens that exposes the film.

error
The difference between the image seen by the viewing system and that recorded on the film. Problems occur as the subject moves closer to the taking lens when using TLR cameras.

Parallax problems-This occurs mainly with range finder and twin lens reflex cameras. The distance between the center of the lens and the viewfinder causes parallax. The closer the lens is focused to the subject, the more evident the parallax.

error doesn't affect SLR because in SLR the viewfinder sees through the camera lens so what the camera sees is exactly what you see. Better high-end compact cameras have automatic correction but even this is not foolproof.

PARALLAX ERROR - Also known as "Parallax effect" - the viewfinder camera's main disadvantage, making it almost useless for careful composition of close-up subjects.


The apparent difference in position of an object when seen from two different viewpoints.

Parallax
Parallax is the image difference between viewing from viewfinder and that recorded by the sensor or the film. The variance will become greater as subjects move closer to the taking lens.

: The difference between the field of view seen through a camera's viewfinder and the image recorded on film by the taking lens of a twin lens reflex camera.

Parallax. An effect seen in close-up photography when the viewfinder is offset by some distance from the lens. The scene through the viewfinder is offset from the scene through the lens.

Perspective - relative size and alignment of objects ...

Parallax - An effect seen in closeup photography where the viewfinder does not see the same as the lens due to the offset of the viewfinder and the lens. This is a non-issue if using the LCD as a viewfinder or if your camera is a SLR type.


The disparity between viewing and imaging angles when they are not identical, as with sports finders or twin-lens cameras.

-Parallax - difference between the image seen by a viewing system and that recorded on film. Only TTL viewing systems avoid parallax error.
-Paraphenylenediamine - reducing agent used in some fine grain and color developers.


The difference between the image seen by a viewing system and the image recorded by the imaging sensor. In point-and-shoot cameras, as subjects move closer to the lens, the variance increases.

Parallax - A focusing error introduced in a typical optical rangefinder at extremely close range; caused by the discrepancy between the optical viewfinder and the camera lens.

Lack of and ability to cope with high zoom-ratio lenses, without the need for a bulky reflex mirror. Cameras with a separate optical viewfinder show the scene from a different viewpoint than that of the camera lens.

To avoid parallax find the nodal point of your lens by guessing at it and rotating the camera around. The perspective shouldn't change between near and far objects, they should remain lined up the whole time as the camera rotates.

With care, error can be made undetectable in handheld panoramas which do not have foreground subject matter.

iOS 7 has a parallax feature that creates a layered experience where app icons appear to jump off the page at you. You may have noticed that if you tilt your iPhone and iPad from side to side or up and down, the wallpaper moves with it.

Generally speaking, is the apparent shift in the direction to an object as seen from two different locations. This shift can be used to determine distances (through "triangulation").

If your camera has a viewfinder in the upper left corner, you may have problems with parallax, especially for close-up shots. This means that the viewfinder is looking at a slightly different area than what the lens is seeing.

TLRs suffer from . The viewing lens is higher than the taking lens and captures a different image. If the image is a mountain 20 miles away, the three inches of separation won't be significant.

OVF focus point parallax error / correction (FW 1.1)
As briefly mentioned above, while the framelines are parallax-corrected in the OVF, the autofocus point isn't.

A disadvantage of twin-lens systems is that errors occur. refers to the difference between the image seen through the viewing lens and the image transmitted to the picture-taking lens (fig. 4-8).

Optical viewfinders suffer from parallax error. As they are not completely in line with the lens, they show a slightly different view than the actual image.

Struggling with problems of moving subjects and viewfinders our first attempts at underwater photography involve getting the subject in the frame without losing any important bits. After mastering this we continue to work at composition.

Click to see the effects of parallax when shooting close to a subject.
In close-up or tabletop photography, digital cameras have a huge advantage over traditional film cameras because you can review your results and make adjustments as you shoot.

When their relationship doesn't change (no ), you're aligned on the nodal point. If possible, you want a good straight vertical line that's close to the lens and one that's near infinity.

A quirk of P&S cameras is that they usually have a parallax error but it's normally corrected for normal shooting distances. This is because most viewfinders are offset to the side of the main lens.

Strobe-mounted accessory lights: In a pinch, you can always duct-tape or rubber-band a small dive light to the strobe head, but there will be . The strobe head will not be lighting exactly the same area illuminated by the dive light.

Panoramic tripod heads are used by many photographers, professional or amateur, in order to maximize accuracy and minimize parallax -- the degree of visible misalignment -- in panoramic photographs.

This achieves what’s known as the effect, where the part of the dog nearest to the camera looms huge and the part furthest away becomes disproportionately small.

Some of the best and brightest trends we've seen this year (2011) in web design include responsive web design, single page scrolling websites, the proliferation of slide shows and sliders, the spread of font replacement and parallax scrolling.

Of note in this category is the shift lens, used for architectural photography, which corrects (or helps correct) error. In simpler terms, this lens helps keep vertical parallel lines parallel, instead of converging.
