These are the most common form of panoramic camera and range from inexpensive APS cameras to sophisticated 6x17 cm and 6x24 cm medium format cameras. Panoramic cameras using sheet film are available in formats up to 10 x 24 inches. APS or 35 mm cameras produce cropped images in a panoramic aspect ratio using a small area of film.
Medium-format cameras typically have format designated by nominal sizes in centimeters (6×6, 6×7, 6×9, 6×4.5), but these numbers should not be interpreted as exact in computing aspect ratios. For example, the usable height of 120-format roll film is 56mm, so a width of 70mm (as in 6×7) yields an aspect ratio of 4:5 — ideal for enlarging ...
Drawing showing the relative sizes of sensors used in most current digital cameras, relative to a 35mm film frame. The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film. [4]
The DCI specification allows several different resolutions for the content inside the container, depending on the desired aspect ratio. The allowed resolutions are defined in SMPTE 428-1: [6]: §3.2.1 [7]: p. 6 4096 × 2160 (full frame, 256∶135 or ≈1.90∶1 aspect ratio) 3996 × 2160 (flat crop, 1.85∶1 aspect ratio)
Most televisions were built with an aspect ratio of 4:3 until the late 2000s, when widescreen TVs with 16:9 displays became the standard. [2] This aspect ratio was chosen as the geometric mean between 4:3 and 2.35:1, an average of the various aspect ratios used in film. [3]
Dual gauge between 1,067 mm (3 ft 6 in) gauge and another similar gauge can make these bonus gauges. 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge, 1,372 mm (4 ft 6 in), (4 ft 6 in gauge railway) and; 1,668 mm (5 ft 5 + 21 ⁄ 32 in) 1,676 mm (5 ft 6 in) (The maximum bonus gauge from 1,000 mm (3 ft 3 + 3 ⁄ 8 in) meter gauge gauntlet tracks).
The most common dangerous goods are assigned a UN number, a four digit code which identifies it internationally. Less common substances are transported under generic codes such as "UN1993: flammable liquid, not otherwise specified". The UN Recommendations do not cover the manufacturing, use or disposal of dangerous goods.
The fourth and final series of Quantum Bigfoot drives produced was the Bigfoot TS series. This series retained the spindle speed and interface speed of its predecessor. The main performance enhancement was a reduction in access time, to "less than 10.5 ms." It was produced in capacities of 6.4 GB, 8.4 GB, 10.0 GB, 12.7 GB and 19.2 GB. [16]
