B lights, the two bs
| Light Glossary |
Back light and background light are frequently confused. both begin with "back," both are used to separate planes and imply depth, and both are tricky to motivate so that they appear realistic. each, however, points in a different direction. tip: discretion may dictate that only one or, on occasion, neither is really needed.to paraphrase shakespeare, in a rather different context: two b or not two b, that is the question.

- Within the gips standards, discretion is the management company's ability to execute transactions and to make decisions regarding the vehicle's investments on behalf of the investors without their prior approval. there are degrees of discretion. however not all investor imposed restrictions or investor approval rights will necessarily cause a portfolio to be non-discretionary. gips describes a discretionary portfolio as one for which the investors have not imposed restrictions or requirements that impede the manager from fully executing the defined and approved strategy.
- Freedom given to the floor broker by an investor to use his judgment regarding the execution of an order. discretion can be limited, as in the case of a limit order that gives the floor broker some distance from the stated limit price to use his judgment in executing the order. discretion can also be unlimited, as in the case of a market-not-held order. see also: market not held order.

Back light, английский
Back light separates subject from background, saints from sinners, and one pro from another. angle: toward the lens from above and behind the subject, or above, behind, and slightly to the side of it, high enough to cut lens flare. it is especially helpful for video images that may suffer loss-of-edge contrast. sins: confusing this source withbackground light, and, for motivation purists, using it at all. tip: smoke, steam, and other translucent subjects adore back light of almost any color.
Black and white (b&w), английский
B&w film offers opportunities and challenges. foreground and background may merge in the absence of color separation. tips: use more back light or background light. view the scene with a b&w viewing glass. other differences: color temperature complications disappear and all those long-abandoned filters that turn blue skies black and trees white can be used again. last tip: while many of the black and white masters aren`t around, their masterpieces are. quote: the most difficult task for today`s director of photography is to "think" in black and white again. he must become mentally color-blind, imagining what each scene will look like on the screen when it loses the colors it has in reality. - nestor almendros [amwac]
