Non-uniform shading in a photograph spoils the
graciousness of a photograph. This non-uniformity may arise due to varying
conditions of illumination. This defect can be rectified with the help of
Photoshop Shadow.
The impact of a dirty lens
can impact the uniformity of luminosity of an image. It may result in an image,
which is lighter in some parts and relatively darker elsewhere. This ruins the
impact of the image. The shade of an
image is the sum of the impact of the camera lens, the lighting during the
time of clicking of the photograph, and the natural filters. A minor change in
any of these may impact the shade of the photograph. The flaw in the shade of
an image can be a result of the illumination at the time the photo is being
clicked. Non-uniformity in the illumination can result in varying degrees of
shades in a photograph. This in effect reduces the grandness of an image.
