  2. Perspective control - Wikipedia

    en.wikipedia.org/wiki/Perspective_control

    The process is known as rectification printing, and is done using a rectifying printer (transforming printer), which involves rotating the negative and/or easel. Restoring parallelism to verticals (for instance) is easily done by tilting one plane, but if the focal length of the enlarger is not suitably chosen, the resulting image will have ...

  3. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism correction is measured in prism dioptres. A prescription that specifies prism correction will also specify the "base". The base is the thickest part of the lens and is opposite from the apex. Light will be bent towards the base and the image will be shifted towards the apex.

  4. Maddox rod - Wikipedia

    en.wikipedia.org/wiki/Maddox_rod

    If the patient saw a red line to the right and white light to the left, they are said to have esotropia or esophoria (uncrossed diplopia) in which base out (BO) prisms of increasing strength are used until the lines are superimposed.

  5. DxO ViewPoint - Wikipedia

    en.wikipedia.org/wiki/DxO_ViewPoint

    DxO ViewPoint is image geometry and lens defect correction software developed by DxO. It is designed to automatically straighten distorted perspectives caused by the lens used and the position of the photographer.

  6. Esotropia - Wikipedia

    en.wikipedia.org/wiki/Esotropia

    Ophthalmology. Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria.

  7. Optical proximity correction - Wikipedia

    en.wikipedia.org/wiki/Optical_proximity_correction

    Optical proximity correction (OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement integrity of the original design, after ...

  8. Laser printing - Wikipedia

    en.wikipedia.org/wiki/Laser_printing

    1984: The first laser printer intended for mass-market sales, the HP LaserJet, was released; it used the Canon CX engine, controlled by HP software. The LaserJet was quickly followed by printers from Brother Industries , IBM , and others.

  9. Camera lucida - Wikipedia

    en.wikipedia.org/wiki/Camera_lucida

    Camera lucida in use. A camera lucida is an optical device used as a drawing aid by artists and microscopists . The camera lucida projects an optical superimposition of the subject being viewed, onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure.

  10. Pentamirror - Wikipedia

    en.wikipedia.org/wiki/Pentamirror

    Pentamirror. A roof pentamirror contains 3 mirrors. A pentamirror is an optical device used in the viewfinder systems of various single-lens reflex cameras instead of the pentaprism. It is used to reverse again the laterally reversed image coming from the reflex mirror. [1]

  11. Horror fusionis - Wikipedia

    en.wikipedia.org/wiki/Horror_fusionis

    In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia.
