Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
Veiling glare in a photograph from Cassini (spacecraft) Veiling glare caused by stray light reflecting inside the camera or scattering in the lens. Veiling glare is an imperfection of performance in optical instruments (such as cameras and telescopes) arising from incoming light that strays from the normal image-forming paths, and reaches the focal plane.

Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
In 1995, Greg Spencer presented Physically-based glare effects for digital images at SIGGRAPH, providing a quantitative model for flare and blooming in the human eye. [ 5 ] In 1997, Paul Debevec presented Recovering high dynamic range radiance maps from photographs [ 6 ] at SIGGRAPH, and the following year presented Rendering synthetic objects ...
For example, if it is known that a lens DoF scale is based on a CoC of 0.035 mm, and the actual conditions require a CoC of 0.025 mm, the CoC must be decreased by a factor of 0.035 / 0.025 = 1.4; this can be accomplished by increasing the f-number determined from the DoF scale by the same factor, or about 1 stop, so the lens can simply be ...

Despite the case being dismissed in July, Alec Baldwin says the story surrounding the fatal “Rust” shooting has only begun. On the Dec. 16 episode of David Duchovny’s “Fail Better ...
As cameras became available to the general public, ghost photographs became common due to natural camera artifacts such as flash reflecting off dust particles, a camera strap or hair close to the lens, lens flare, pareidolia, or in modern times, deceptions using smart phone applications that add ghosts images to existing photographs.
