  2. Brenizer method - Wikipedia

    en.wikipedia.org/wiki/Brenizer_Method

    The Brenizer method increases the effective sensor size of the camera, simulating the characteristics of large format photography. [ 2 ] While the aesthetics of this form of imaging most closely resemble large format analog photography, its look has also led it to being compared to tilt shift photography .

  3. Tilt–shift photography - Wikipedia

    en.wikipedia.org/wiki/Tilt–shift_photography

    The earliest perspective control and tilt–shift lenses for 35 mm format were 35 mm focal length, which is now considered too long for many architectural photography applications. With advances in optical design, lenses of 28 mm and then 24 mm became available and were quickly adopted by photographers working in close proximity to their ...

  4. Zone plate - Wikipedia

    en.wikipedia.org/wiki/Zone_plate

    In the long focal length limit, the area of each zone is equal, because the width of the zones must decrease farther from the center. The maximum possible resolution of a zone plate depends on the smallest zone width, Δ l Δ r N ≈ 1.22 {\displaystyle {\frac {\Delta l}{\Delta r_{N}}}\approx 1.22}

  5. Focus stacking - Wikipedia

    en.wikipedia.org/wiki/Focus_stacking

    Focus stacking – also called focal plane merging, z-stacking, [1] or focus blending – is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images.

  6. List of standard zoom lenses - Wikipedia

    en.wikipedia.org/wiki/List_of_standard_zoom_lenses

    There is no precise definition of the term, but lenses marketed as "standard zoom" usually cover a range of at least 30mm to 70mm in terms of 35mm equivalent focal length with an optical zoom ratio of 2.5× (e.g. 28-70mm) to 5× (e.g. 24-120mm) — the most common being 3× (e.g. 24-70mm). [1]

    Flavin previously revealed how the breakup happened in a 1994 interview with PEOPLE. "He sent me a six-page handwritten letter, in pen. It was pretty sloppy," she said at the time. "You can't just ...

    Criteria relating CoC to the lens focal length have also been used. Kodak recommended 2 minutes of arc (the Snellen criterion of 30 cycles/degree for normal vision) for critical viewing, yielding a CoC of about f /1720, where f is the lens focal length. [8] For a 50 mm lens on full-frame 35 mm format, the corresponding CoC is 0.0291 mm.
