DIVERGING LIGHT RAYS - Light rays that continue to recede from each other.
DODGING - Blocking a portion of the light when printing a photograph so that an area of the print will be made lighter.
Diverging lens
A lens which causes rays of light coming from the subject to bend away from the optical axis.
DMA (Direct Memory Access)
Allows the I/O subsystem to access main memory for the transfer of data.
Severe diverging verticals can be seen in this image, but the lines of the distant buildings are perfectly straight.
Also known as a reverse or inverted telephoto, this lens design has a diverging lens element positioned in front of the aperture and a converging element positioned at the rear.
Diverging patterns, on the other hand, involve one or more shapes that diverge from the rest-imagine a grove of trees aligning vertically, except for one tree that is tilted at a diagonal angle.
In this simple optically compensated zoom lens, the afocal system consists of two positive (converging) lenses of equal focal length (lenses L1 and L3) with a negative (diverging) lens (L2) between them, ...
The rays of light all start at the same point -- the candle's flame -- and then are constantly diverging. A converging lens takes those rays and redirects them so they are all converging back to one point.
Telephoto Lens A specific type of long-focus lens in which a positive (converging) lens element is placed in front of the diaphragm and a negative (diverging) lens element is placed at the rear of the diaphragm.
Without going into the physics used for each, the main shapes are: plano convex, plano concave, converging meniscus, and diverging meniscus.
to wideangle lenses, the back focus is designed longer than the lens' focal length to allow clearance for the movement of the reflex-mirror (No Mirror Lock up or seperate viewing accesory attachment is required). It consists of front diverging apd ...
the light is refracted. The incorporation of various lenses (converging and diverging lenses) creates a lens system. When optimally arranged, they allow the subject to be presented correctly on the image plane.
Nowadays one, some or even all element surfaces of a lens get a transparent special coating against reflections between the elements. The elements are classified as converging (light-bundling) and diverging (light-spreading) elements.
