Digital jvc gz-mg21u charger because tolerance is small, the performance not so much black and white silver gray levels, there are some flaws. But the most basic, black, white and middle or can shoot out of tune, of course, there is no silver so many levels, expressive worse. Therefore, more should pay attention to when making the exposure, I generally feel: high light over not more than two, less dark can not be lower than 3, the maximum tolerance also in 5 or less.
Means that the range to shoot you, if you want to show every detail of the screen, the brightest and darkest areas where exposure to 5 or less difference. For example: use spot metering, aperture priority mode to capture, set the aperture F5.6, if the brightest point on the screen as the shutter speed 1 / 500 seconds, then the darkest point not lower than the shutter speed 1 / 8 seconds, otherwise the dark can not see the details. This tolerance should be a SLR digital data, for universal DC, because the CCD is smaller, even smaller tolerance! So why the same 4M pixels, 1/1.8 inch CCD camera will be shown the picture quality is better than 1/2.7 inch. In addition to noise factors, tolerance is a big difference.
Understand the exposure characteristics of DC, and then look back and say how the exposure. In fact, under natural conditions, most of the light than in the scene (that is, the brightest and darkest brightness ratio) is far more than five, and we take a film, not all need to have all the details performance clearly. Therefore, by determining the proper combination of exposure to the performance of the photographer's creative intention is very important. Leading authority in this regard was undoubtedly the United States, Adams, he founded the partition exposure method is a milestone in photographic technology. Exposure to more clearly partition method is probably not able to solve this little post, but its principles are not complicated: whether film or CCD, the sensitive natural environment of tolerance are less than the brightness range, Adams put the brightest (white ) to the darkest (black) is divided into 10 regions (later he was further divided into 11 regions), usually black and white silver halide film can be expressed in the seven regions around the performance of color negative film can be roughly 6 District, color reversal film and DSLR's CCD can be expressed in five general areas, and general popularity of small digital type can be expressed also about 4 to 4.5 zone.
Therefore, in shooting, the first intention of the shooting, make sure you tune to the middle of the (so-called 18% gray, which is the basis for calculating the camera metering) where then need to keep the details of the screen at the brightest and most dark point of measurement, to see whether the brightness beyond the scope of the performance, if exceeded, you need to think of ways it! For example Backlight Portrait, metering prevail if people face, the background is too bright high-gloss necessarily serious, if there are details that require high light, it must improve human facial brightness in order to reduce the brightness of the picture is poor, usually we can use flash fill light or reflectors fill light. To cite a contrary example: cloudy portrait, the light at peace is not taken out of the three-dimensional characters, especially in black and white photo, is all the ash into one, this time need to use flash or lights to improve people brightness If the lights to play in the human face, is still subject to exposure to the face, then naturally lack the background brightness of the dark down, so the principal came out very clearly highlighted.
When shooting landscapes, we often encounter a scene: blue sky with mountains, the human eye looks very beautiful scenery, can take back either the blue and white photographs, dark below, or is the Castle Green water, a dead white sky, which is a typical scene brightness than the actual light-sensitive material (film or CCD jvc gz-mg30u charger) caused by tolerance, the traditional solution is to add a polarizer, or lost in the gray gradient mirror part of the sky brightness, reduce the brightness range, the image brightness can be expressed within. Another method is particularly suitable for DC, is making two, one with the sky exposure subject, a subject exposed to the ground, and then in Photoshop, two synthesis. Note that this approach is best to use a tripod to ensure the two films do not change the location shooting, or in the synthesis will be trouble later.
From the above, understand the film screen brightness information of each region get a proper picture exposure is very important, so the spot metering function is very useful, and now most popular digital camera on a little metering, Of course, this "point" of the area and the traditional "point" seems too big compared metering, but good enough under normal circumstances. Use spot metering to note two points: First, any metering are based on 18% reflectance gray board conditions, that is obtained in accordance with the exposure metering value is a grayscale image to 18%, 18% ash degree in general close to the Chinese men back of the hand. Second, get the exposure metering value is determined after the requirements of the two literally the middle of the screen gray tone as the center, to keep the details of the intensity should be within plus or minus two. Example shows: take a sun flower, background trees, backlit shooting. We must first determine the content of expressions: one flower, the need for a fairly complete detail; the second is the background of the trees, hope and spend significant color, gray scale changes, and if flowers are light, then hope that the background is dark to highlight the flowers, the color match on the composition and not to consider here. Well, how do we take it? First, direct sunlight, illuminating parts of the petals are very high brightness, and the other not illuminated at compared to the brightness difference often are beyond the scope of CCD jvc gz-mg20u charger can express so directly out of the film shoot, or else No details have to spend a block of dead white, or else there is a round dark spots do not see anything. The cure is also very simple to prepare a white, tracing paper and better use of sulfuric acid, softens the sun above the subject, reducing the ratio of light and dark light, so that you can guarantee the flowers light and dark exposure tolerance in the Department of range, can show enough detail.
Secondly, we do not want to spend the brightness or color background and flower are similar, this will not cause the main highlight, a means is the use of large aperture telephoto lens or macro lens in the background aerosol, and the other is to select the background in the backlight side, so that because the brightness is insufficient, in order to take the case of exposure subject to the natural dark down, of course, the darker the background is not necessarily better, sometimes the details of an appropriate theme for the show is a great help.
Finally talk about the exposure of problems in black and white photography JVC Charger, black and white photography is not the color of the factors that relies entirely on changes in the expression of the brightness, so black, white, gray on the composition of a picture is essential, in addition to the changes constitute a tone In addition, lines of different brightness, the screen area is composed of core elements. And black, white, gray, in many cases is also shown by comparison with each other. So when shooting black and white, but more accurate picture of the screen's brightness and contrast form factors to determine the exposure based on combination of creative intent.
Black and white photography in particular to note that some of the eyes look very different things in the world is difficult to distinguish between black and white, such as red flowers and green leaves in the world of color contrast is very clear, but in black and white conditions, are expressed as gray, and the brightness difference is small, so when shooting, if you want to show the difference between green leaves red flowers, you need to use filters, of course, in the DC color to black and white film when the red channel can be selected, discard the other channels, sub- black and white approach.jvc gz-mg130 charger
