vignetting वाक्य

The sleeve is threaded, making it compatible with 72mm filters, but vignetting is severe with the sleeve in place.
When using superzoom lenses, vignetting may occur all along the zoom range, depending on the aperture and the focal length.
The brightness variation due to vignetting, as shown here, can be corrected by selectively brightening the perimeter of the image.
This optical combination prevents the image vignetting or going dark when the binoculars are pitching and vibrating relative to the viewer's eye.
This ease of placement helps avoid vignetting, which is a darkened or obscured view that occurs when the light path is partially blocked.

Another method that can be employed for articulation is called vignetting, or the inclusion of brightness gradients at the land-water edge.
These lenses generally exhibit vignetting at shorter focal lengths when mounted on Nikon film bodies, but are typically usable at longer focal lengths.
The ED 300 mm f / 4 IS Pro has an excellent image quality with low aberration, low distortion and almost no visible vignetting.
Typically the image circle produced by a lens is large enough to cover the film or sensor completely, possibly including some vignetting toward the edge.
On an APS-C body, the lens shows almost no vignetting, even at its maximum aperture, 5.6, at 350mm.
