Цитата:от:G o r d o n
Ты будешь смеяться, но я сейчас порылся в старых равах с д90, и у меня создалось впечатление, что его авто-ББ был малость поточнее, чем у семисотки... может, потому, что позже вышел, доработали чего-то... И если он ошибался, то обычно в помещении (при естетвенном свете), и напротив - в желтизну... Впрочем, семисоткой в таких условиях я пока почти не снимал, может, она так же будет... В общем, вот откуда несоответствия в показаниях... у одних желтит, у других синит... а это просто на каждой тушке по-разному... :)Подробнее
Digital cameras fare less well using the Automatic white balance setting with light that falls under 4000K (note that Nikon doesn’t recommend Auto below 3500K for the
D700; yet I find that even at 4000K the camera tends to set a white balance that’s a bit too high in Kelvin for the light). That’s partially because the blue sensors receive very little information at these so-called “warm” color temperatures, so the minute amount of blue wavelengths being seen by the sensor becomes a factor.
One novel way of coping with the problem of getting good automatic white balance with indoor light is to simply do what we used to do with film: use an 80B filter! The 80B shifts the 2900K color temperature of a 100-watt bulb up to about 4300-4400K (an 80A would push it above 5000K), putting it within the range the camera handles well.
Tip: Nikon’s choice for normal outdoor lighting (5200K) should raise eyebrows, though I haven’t seen anyone specifically comment on it. Daylight film is usually balanced to 5400K, and many digital photographers set their default daylight value even higher. (The origin of the 5400K number, by the way, is interesting—it’s the average measurement of color temperature, taken at noon on summer and winter solstice on the Mall in Washington DC in 1926! Since altitude, time of day, time of year, cloud cover, and distance from the equator all alter daylight color temperature, one value does not apply to every situation.) Don’t be afraid to experiment a bit to find the white balance you like best. In general, I find that Flash a2 is the quickest way for me to set a sunny white balance I like, and I also tend to use much higher color temperature values than Nikon suggests for most indoor lighting (e.g. Incandescent a1 or a2).
