Digital camera photography
With the increasing popularity of digital, digital camera ( DC ) is no longer rare objects. While digital today, the people in the original shooting skills based on the proposed new requirements, many primary digital users reflect: digital camera shooting out of the picture dim, lack of energy, noise, depth shallow ( especially in macro mode ), partial color. But photography is the soul and light bridge of communication, to master the traditional shooting skill is not easy. Now let me to introduce digital camera in shooting necessary to pay attention to the problem, at the same time also tells the story of some images taken before and after the note.
Many users don't like thick and complicated product specification, general to buy a digital camera to buy back all like his own. Of course, in the exploration process there will be some surprises, but it will take a lot of time, but also can in the shortest possible time system to get your hands on the characteristics of the product; if you read the instructions say after the operation it can avoid some mistakes in operation. So in the early exposure to new, should briefly to browse a manufacturer for everyone with assembly instructions, with the basic digital camera menu functions. Later when some unknown can be doubled it, will be harvested.
We want to choose the reasonable pattern, we are very clear, digital photo quality and pixel ( resolution ), the pixels the high image quality will be. But the actual situation is computative,2000000 pixel digital camera about1200 DPI scanner with the same digital image capturing ability, and the6000000 pixel digital camera can be regarded as with 2400 DPI scanner at. If you just use a general platform for photo digitizing scanner, so as long as 2000000 to3000000 pixel digital camera can be easily more than35 mm camera. However, if the output of the 4" X6" size, about A6, use the 200-300Vientiane plain enough to meet the needs of ordinary people. If the computer is used for72 DPI display, requirement is lower, the resolution is 1024X768, only about 800000pixels, any one of two million levels of DC can do a job with skill and ease. Because digital camera storage space is limited, so we want to suit one's measures to local conditions, a reasonable selection of resolution, such as : for PC, for my SONY DSC-S75generally use 1280X960; such as used in printing, generally use 1600X1200; take life as well by 2048X1536. In the case of less demanding, compression standard has adopted STANDARD, rather than FINE compression save more than half of the picture!
For photography has a certain understanding of the digital users, are clearly the importance of accurate composition. Such as: if not close-ups, should generally be putting your subject in the frame of the1/3, at the same time as far as possible to avoid clutter background, from the special angle to shoot, try to capture the object details and personality, using some diagonal lines or curves background composition will make the whole picture look more vivid. In addition, we must make good use of two-dimensional vision observation. Because photography only two-dimensional space, the perspective relation (i.e., light and shadow shape effect as a frame of reference ) to express the sense of space, is different from the two different point of view to observe things three-dimensional eye. However, most of current digital camera has the intuitive LCD viewfinder screens, and the field rate all be in 90% above, some close to 100%, such as S75amounted to 99%. Can say without mincing words observed in the sense of space and sense of distance is enough, can make timely adjustment. But the general digital camera LCD resolution are relatively low, clarity is generally unsatisfactory, but I I to S75 or very satisfied. But it is not superstition in it, because in fact found in: display in LCD minor excessive exposure, the computer monitor display exposure measure just. It is also part of the user always take a dim because of. But LCD power consumption has been made" Shaiyou" have a headache, so many" Shaiyou" in shooting still accustomed to the use of an optical viewfinder, on account of an optical viewfinder view rate of only80%-90%, and shooting in the near feature also remember it but paraxial! Of course, to take a spectacular picture have close one eye, with two hands, the thumb and index finger on a" frame", the scene as a printed book or a painting hanging on the wall ... In short, the camera is filming ended, composition and reflection is the key.
Don't believe the DC automatic mode. First of all, and the traditional camera, another big difference is that DC has a white balance. This is similar to the traditional photography in color, it is due to the novice is not attached to the white balance, so will produce color deviation. DC generally provides automatic, indoor, outdoor, four kinds of manual mode, beginners can trust AUTO, can often take a picture by a color, as long as we carefully note the LCD viewfinder is can be seen. When we just shot into a real, the real generally in favour of one color, if blue, then DC white balance automatically tend to blue, then shoot other objects is the natural color of the will. So while LCD will be reflected, but beginners generally not found. At the same time, some of the patterns are not perfect, such as: SONY DC in an indoor mode is" blue syndrome" situation, so we'll try to use manual white balance as well. But, also pay close attention to LCD color changes, finding the white is white, will be on white real light extraction correcting white balance. In addition, some digital cameras also have automatic enclosing white balance function, in order to record accurate color information.
Secondly, aperture, shutter control. Suggested that the manual should also use manual mode, because the automatic mode usually projected picture dim, especially within the window, too much noise. Because in the indoor photography, DC general automatic lifting of ISO values, such as: SONY DSC-F505V in indoor generally amounted to about 282, whereas the sensitivity and image quality of inversely related, namely the equivalent higher sensitivity, image quality is poorer. This and traditional photographic materials with properties similar to, but in the digital camera this characteristic is more obvious. Because the traditional photography, we select different sensitivity of film or through the " fast sensitization" to change the time sensitivity, but digital camera can't do this, it can improve the sensitivity of CCD and the gain of the circuit to improve the response speed of CCD, the sacrifice of filtering performance and resolution indicators for the price, doing so will produce a signal noise problem, and finally in the picture on the left traces, this and traditional high sensitivity of coarse particles is similar to film. So in the digital camera, to obtain good image quality should be as far as possible to choose low equivalent sensitivity, or directly fixed to a minimum.
Again, DC has a macro mode, and the digital camera wide angle are generally larger, up to about F2.0. In the automatic mode, the camera program also tend to use a larger aperture so as to shorten the time, prevent vibration. But photography common sense tells us, the camera lens contraction generally from the maximum aperture contraction of about two photographs effect best. Especially in macro mode, such as: SONY DSC-S75 in take some mobile phone keys, only the middle part is clear and exquisite, surrounding with a slight blur. Therefore, we had better use the aperture priority or full manual mode, the use of smaller aperture in order to extend the depth of field. If the camera is not aperture priority function, can try to improve the brightness of the environment, the camera automatically select a smaller aperture or the use of flash, the image quality can be improved.
Correct use of light and light, to learn dialogue. Light is the soul of photography. So we should pay attention to the change of light, is not only the intensity of the light, and the direction of the light, light heart and dialogue. Such as: sunset to sunset dyed red, symbolizing the romantic; dark sky grey cold colors, symbolizes the blue shade; remove a ray of sunshine, happy, cheerful sentiment transmission ... ....
Resolution of the intensity of the light
Hard light usually consists of a single light source, for example: the sun, the spotlight, flash or single bulb. In this light, the object contrast, details and textures to be outstanding. You can use this light to obtain the effect of documentary.
In contrast, diffuse light produced by a light soft. Indoor indirect lighting, outdoor shade and cloudy days belong to this situation. In this light conditions in portraiture and tranquil outdoor scenery is ideal.
Stress optical angle
The angle of light different, object texture can accordingly be strengthen or weaken, the object shape will be highlighted or weakened. Photos of the tone is happy or sad, also because of the angle of light vary. From above or behind the camera ( often referred to as the front light ) from light will reduce the object level of sense, reason is to create a positive light not lighting and shadows. The better choice is to let the light source is biased towards the side of the same object, about 45 degrees angle of side light, it can be a good performance of the object shape and details.
When light from an object behind shooting, facing the camera produces backlighting. Shoot the targets in the backlighting is dramatic. In portraiture, backlighting in the characters' hair marginal produce beautiful contour light. Contrast large surface can produce the silhouette effect.
Digital camera photography
In traditional photography, a not allow to neglect is not easy to master the color problem, in a digital camera has ceased to exist, because the digital camera through the white balance to adjust the solution, without considering the color temperature of the light source and the negative relationship. This is one of the great advantages of digital camera.
Digital cameras compared with traditional photographic materials, especially the new dye type photosensitive material, digital camera in exposure tolerance index no advantage, so when shooting accurate exposure still digital camera to obtain good image quality, basic principles. In practical use, we found that the digital camera to light more demanding, in the indoor photography is particularly important. Therefore, we in the indoor shooting if not another lighting, should as far as possible the use of flash.
During the filming, we need to pay attention to several errors.
The habit of using a UV filter
As for traditional photographer, UV lens is one of the essential. But because the DC light sensitivity to light wave interval end offset, that is to say on the red and infrared light sensitive to blue light ( especially UV ) is not sensitive. So in the digital camera with UV lens will not get the desired beneficial effect, and the optical properties are not good UV lens will produce negative effect on imaging. So, UV would not be.
The three foot was then
Don't think that in addition to professional photographers or those avid photography enthusiasts, the three tripod for digital camera without the land. Because of the need to take a clear image, photo must be absolutely steady your camera, even the most minor jitter can cause blurred image, but also for the results we tend to be at a loss what to do, not through the post production to eliminate this effect.
Of course, using common film cameras also have this problem, but due to the digital camera's light sensitivity is low, and it needs a series of circuits, presence of shutter delay problems, such as: S75 shutter delay of nearly 0.1S, than with fast film film cameras require a longer exposure time, in when the light is weak, even more so. In order to stabilize the camera, shooting should be as clamping elbow, and should be put to the most stable part of the forehead, and gently press the shutter. But the best way is to be a camera mounted on a three leg, or placed on a desk, counter or other not moving objects. Especially in closeup shots or macro photography, using three tripod will get a better shooting effect.
Disregard for post processing
Digital camera digital image, only a handful of seems perfect, in fact, with the average film camera is so. Of course, the digital image advantage can be processing, but one would think it has lost its" fidelity " true meaning. In fact, it is still in the photography foundation, through creative ideas, using a variety of digital technology, the photographic material or combination optimization, thereby insipid for magic created works of art.
Knowledge in the use of value - - Application in practice
Is not necessarily" much work of art.", but to" art." need to" work ", digital photography is no exception. So, as far as possible in different light conditions take lots of pictures. Shoot shot records, pay attention to use the camera settings and lighting conditions, and then the research results, have a look which under the conditions which the best setting. Professional photographers in the photo on the same image must be shot several times, each time to change the camera angle or exposure time setting, we ought to be doing it. Most digital cameras are LCD display, you can use it to easily observed and remove you don't like images, so do not worry because of " excessive shoot" caused by low memory capacity, despite the reassuring to shoot a variety of exposure of the image, thus, eventually there will be at least a good picture.
