Hobbies & Home Entertainment Photography Light bulbs USED color photographs of the spectral straluma characteristics of ambient light tubes used in color photography spectral characteristics
Incandescent lamps - their color temperature straluma - 2800 - 3500 K, so shooting with such lempom color photo on the tree. (Daylight balanced) straluma must use the conversion filters, causing the lens of light color temperature.
Fluorescent lamps - masher at low temperatures, their spectral char. - Ing depends on the type of phosphor and color temperature of 4700 - 6700 K. Their power small - 15-80 W, duration of work - 12,000 hours ..
Pulsed lamps - emit a brief, high-intensity flash of electric-discharge time. Spectral composition of the light is close to the daylight, the color temperature is through the use of inert gas, the pressure, and the electrical circuit reaches straluma 5500 - 7000 K.
Light: Light Piešiančioji - regulates the frame color the drawing lamp with kriptingą beam formers. The average diameter of the reflector (which may be carried out with leaves). Lamp with 1000 - 500 Watt. Lamps can be used for: warm white (day Saint.) Mirror (to kriptingą light flow inside the lamp, covered straluma with mirror, lights matte top) or with overheating straluma Work hours. - 3h. To this combined light and other lights. Pay attention to the cap - or even thread. šv.- fills it helps to highlight straluma the texture and colors. Must be less powerful 2x - 250 W, or powerful, but then managed periostatu straluma (transformer). Reflector has a large format. Before straluma the light bulb is dispersants, as it shiny surface, the harder lighting. The surface should be matt, rough, glossy, straluma - helps create soft lighting. Prohibited coated paper - light up. When working with high-powered lamp can not be the first to open the petals, and then turn off. It is first necessary to turn off and then the tab. Because the temperature difference can lead to explosion. The lamp is constructed of 30 degrees on either side of the background, combined to piešiančiosios light. Modelling - must be the reflector depths. light background: has a special meaning sp., Capture-in. The result is a color contrast between the subject and the background. Combined eyes, hair, clothing and background color, background harmonious. Gives a narrow straluma beam with a small diameter, 60 to 10 Watt lamps, working hours - 3000 hours. Day lamps, 5,000 hours. incandescent lamps. background light - 60 W power. Lamp hanging on the ceiling, is dissipated. Lenticular chandeliers lighting can enter into an oval.
Solutions: ryškinančiomis straluma trees. For different requirements, because straluma they have to react with halogen illuminate Ag and components and to paint, dye near Ag grain formed dye molecule. 1st material more active, more toxic, used negatyviniame process, 2-pozityviniam it. Their physical appearance - this pale pink hardly soluble in water. The first material results in a higher yield of dye, tom flexible use and need to charge less, and need to take a second shot over 1.5. The most important materials and color purity. Multipurpose cache. Used weak alkalis (potash, soda). Better nauduoti PATAŠIAUS because straluma soda is often impurities to form colored veils. must have a pH from 8.8 to 11.3. PATAŠIAUS concentration should possibly 1l from 50-80 g. The soda 40-70 (1 l). If the number straluma of trees to increase straluma cache the image quality will deteriorate. With good buffering (keeps constant characteristics). Tinning trees. Prevents fast-developing Multipurpose oxidize, it is placed so low that it binds-developing Multipurpose oxidation products straluma making up the paint. If you will be adding more than 2g, then a pale colors placed in 1 liter of 0.5 g to 2.5 g of Aquarius. straluma It can also be used for hydroxylamine sulfate, if these trees will be more it will highlight it in the exhibition halls Ag paint does not cause an oxidative form. Priešvualinės trees. - Helpful. straluma KBr. Developer I added 0.5 g - 2 g / 1 liter. can be placed and benzotrezolis (nuo1g-10g / l) if KBr with benzotrezoliu helpful. If there is a lot of bromide reaction slows down - there veil. If more material prišvualinės optical density decrease in negative KBr amount straluma depends on the pH indicator, the higher the pH the more need KBr. KBr-developing Multipurpose enhances selectivity. (RM is the ability to select and highlighting only the influence of light hal Ag crystals). Supplementary visualizing trees. - This takes place in an acidic environment ryškinimas. Aim is to raise the sensitivity. PH 4.0 to 5.0 is used KBr added 2g / l Lock tree. - Better nauduoti neutral fixer as sour fade colors. May be used in addition amoniotiosulfatai. Prevent the fixer splashing into the Developer, because we get a red veil. Fixation duration straluma depends Natiosulfato concentration straluma and solution temperature. Bleaching trees. Whitening your essence l., Similar to the downsizing remain unanswered photography.
