UEIT - Universal Electronic Test Chart (russian: УЭИТ - Универсальная электронная испытательная таблица) is a Soviet/Russian test card, designed to test TVs operating in the analogue SECAM colour standard.
Polaroid Now+ Generation 2 [19] Polaroid I-2 (2023) – one 98 mm f /8 lens with lidar autofocus; shooting modes available from the camera itself include automatic, shutter priority, aperture priority, and fully manual. (Note: lens equivalent to 38mm equivalent angle of view and f /2.8 in 35 mm film or full frame digital format.) [20] [21] [22 ...
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.

The first roll film camera was the Polaroid Model 95, followed by subsequent models containing various new features. Roll film came in two rolls (positive/developing agent and negative) which were loaded into the camera and was eventually offered in three sizes (40, 30, and 20 series).

An APS-C type lens often does not have the coverage to cast light on the entirety of a 35mm sensor, causing dark corners in the images. [2] One common misconception about lenses is that focal length determines the angle of view for a lens, when in reality it is a combination of focal length, lens coverage, and sensor size. A lens of a certain ...
where V 1 and V 2 are the Abbe numbers of the materials of the first and second lenses, respectively. Since Abbe numbers are positive, one of the focal lengths must be negative, i.e., a diverging lens, for the condition to be met. The overall focal length of the doublet f is given by the standard formula for thin lenses in contact:
