21. Most commonly, the 35 mm equivalent focal length is based on equal " diagonal " angle of view . 22. Mechanical and electronically steered arrays offer a wide view angle of 90?steerable for a 360?angle of view . 23. When viewed at this distance, the distortion effects created by the angle of view of the capture are apparent. 24. The resulting 3 element lens has a narrower aperture of f / 12 and an angle of view of 40? 25. "' Digital zoom "'is a method of decreasing the apparent angle of view of a digital photographic or video image. 26. The apparent brightness of a Lambertian surface to an observer is the same regardless of the observer's angle of view . 27. :Iridescence means it " appears to change color as the angle of view or the angle of illumination changes ". 28. These special effect pigments, such as ChromaFlair, exhibit strong directional spectral reflectance and colour shifting with the angle of view . 29. As noted above, a camera's angle of view depends not only on the lens, but also on the sensor used. 30. In the study, Schiler wrote that the hall sparkles in the sun and changes with every different angle of view .
