| Our design minimized the distance between the objective and tube lens to avoid vignetting, which resulted in lower light levels at the edges of the image. |
| Reducing the facet length will increase vignetting at the edge of the scan line but may be a good trade-off depending on the application. |
| Also if you stack several filters together you are much less likely to get vignetting. |
| There is another way of vignetting the sky into the landscape, which is, perhaps, better and more convenient. |
| This acts as a frame to hold the vignetting mask, which has the opening of proper size and shape. |
| Colors, detail, vignetting, zoom and speed have all been examined under the microscope. |
