Regional exposure,nikon d90 battery also known as partition exposure. By Ansel Adams is (the) first proposed Adams.
Regional exposure, according to the characteristics of the film is sensitive, which is divided into 0 to 10 different density of the area, the division of the regional
corresponding to the film completely photographic curve.
Have you can do a film condition of the experiment, no photographic curve conditions is only related to examine the books. The following is my exposure to partition
the experiment, online and will to discuss common taken friend division exposure.
According to the principle of division, in shooting exposure before I choose furniture partition, as shown in figure 2 shows each division. 1) : 0 for the scenery area, where the shooting out of the dark, after photos nikon d7000 battery of the deepest part should be elucidated; 10 for the scenery area, the bright place, after
shooting out of the picture should be elucidated shallow parts. 2) : division 1 and 9 area for effective image area; 2 to 8 area for texture, can express area detailed records of the scenery of the texture. 3) : the fifth district supplied reflective rate of 18% for the object to the neutral grey building should produce consistent. Adjust good composition of each division, after exposure index measurements. With the measured area 5 exposure index for exposure. Shoot the picture 4
In figure 4, in the dark, not the 0 details down, 10 division also no record levels, the two area just corresponding to photographic film the toe of the curve of the
shoulders.
1 to 9 area for image area of effect, in this area, 2 to 8 area for texture, can clearly express area to see in this section of the detailed record scenery texture, and 1 area
and 9 area, can see the less obvious details and level.
In order to further understand the meaning of the exposure, I division reduce the level of exposure, according to 6 zone exposure, shooting out of the figure 5, in the
photo due to reduced exposure, the whole building is very dark. Originally the scenery in 2 because of exposure to reduce, fell in district 1, detail also lost; But in
the,9,10 highlights part is 8 district but the exposure for the reduced, level a figure 4 had relatively good performance.
To sum up, the exposure for photography, is in order to record the photographer nikon d80 battery want to express intention. The photographer according to different expressing
intentions, taken of objects of different exposure, so as to achieve the effect of different shooting.
Pipe in the past 2006 years, the whole digital camera canon powershot sd300 charger industry momentum of development is very fierce, portable consumer machines, high-end DSLR unconventional all the way. But in the telephoto consumption field, it is flagship situation is not optimistic, and as the price is no longer competitive, function and for digital SLR to more than the simplified, make product final consumer groups in the fuzzy sense. It also led directly to consumption flagship currently abnormal embarrassing situation, a little high levels of photography enthusiasts a move into the low-end SLR to embrace, and beautiful and practical for the demands of ordinary home users will prefer up similar ricoh R5 telephoto of cabinet. Time "consumption flagship where the?" Questions become landscape.
The 2007 years of January 25, Olympus gave us a reference answers, its SP series models in the newest telephoto main SP 550 UZ formal released.

At first sight SP 550 UZ, really feel and the same period the small digital canon powershot sd200 charger Olympus released SLR E-400 some spirit likeness, as E-330 to E-the great changes in 400, the Olympus change color, not only the previous series of an unprecedented loading focal length to 28-504 mm (equivalent focal length) big zoom lens, SP 550 UZ of the overall appearance is to design, with all the metal material qualitative make change, and the outer black to whet a sand material package, let the fashion silver metal and black to whet a sand color mutual reflect, and in the machine on the key operate, citing the Olympus E series digital SLR, let some of the concept of operations and professional portable consumption details of the operation bring out the best in each other. This also is at present mainstream telephoto model lacked.
Now that the price and the characteristic all have, the rest of the only actual performance, after all 18 X optical zoom in carrying FangDou CCD after shooting performances have DuoDa ascension practical? The supreme ISO5000 mode of the usability and how many? With these questions, let us into the following article actually. A look at evaluating
SP 550 UZ the suffix "UZ" is the mk-ultra complex modulation Zoom had written, said it belongs to Olympus telephoto series DC. Say to the camera, and ordinary people may telephoto first thought of Canon S x, SONY IS series of H series, Fuji S9600, S6500fd and other products, but these in the final analysis can only be regarded as the current stage of the more well-known just. Really want to calculate the earliest telephoto camera up, or the Olympus.
