With the continued popularity of digital, digital camera (DC) is no longer a rare object. The digital technology of today, the original shooting on people based on skills and also sets new requirements of many primary users Fanying: Shumaxiangji captures the image dim, Qianquehuoli, noise Duo, scene depth (especially in macro Moshi under), color cast and so on. But photography has always been a bridge between soul and light, to master the art of traditional photography is not easy. Let the following paper we describe briefly the digital camera to capture the necessary attention in the issue and also about some of the issues before shooting. .
1. Browse brochures.
Many users do not like thick cumbersome product specifications, general purchase after buying a digital camera like exploring on their own. Of course, in the exploration process will appear with some surprises, but will spend a lot of time, but not Yi shortest time system know your hands the product of Texing; If you read the Hua Yue Ming Yue Huan after Caozuo avoid some of Cuowu operation. So at first contact with new products should be a brief first visit back to manufacturers for the compilation of all the instructions carefully, familiarize yourself with the basic digital camera menu and function. Later can be unclear to double it, and will be harvested. .
2, rational choice of image format.
We all know the quality and pixel digital photos (resolution), of pixels the better the higher the image quality. The projections by the actual situation, two million pixel digital camera around with the 1200 dpi scanner have the same digital image capture capabilities, and 6 million pixel digital camera can be treated as 2400 dpi scanner at the same level. If the platform is the use of general digital photo scanner, digital camera so as long as two million to 300 million pixels can walk away from a 35 mm camera.However, if the output 4 "x6", about the size of the A6, the use of 200-300 million pixels enough to meet most people's needs. But if we only used the computer monitor 72 dpi, the lower the resolution of 1024 x 768, only about 80 million pixels, and no one to two million-level DC can ease. Because the digital camera storage space is limited, so we have to local conditions, rational use of resolution, such as: only for PC's, for my SONY DSC-S75 general use 1280X960; if applied to printing, generally use the 1600X1200; photo shoot when the course of life with 2048X1536. In less demanding situations, compression standards are used STANDARD, FINE compression standards that exist than more than half of the picture too! . .
3. composition and thinking.
The photography has a certain understanding of users, both recognize the importance of accurate composition. Such as: If it were not shooting close-up, the general subject on the screen should be 1 / 3 at the same time try to avoid the messy background, taken from a particular perspective, try to capture the details of the object and personality, using a number of slash or curve background layout will make the overall picture look more alive. .
In addition, we want to be good at using two-dimensional vision. Because photography is only two-dimensional space, its relationship with perspective (i.e. the shape of the light and shadow effects for reference) to express the sense of space, different from the from two different angles of three-dimensional human eyes. However, at present, the vast majority of digital cameras has intuitive LCD viewfinder screen, and its vision of the rate is over 90%, some close to 100%, such as the S75. Can be directly observed on the sense of space and sufficiency of sense of distance, you can make timely adjustments. But most digital cameras are relatively low resolution LCD, resolution not generally satisfactory, but the brush on the S75 is quite satisfactory. Can not superstition in it, because in practice the use of that: in the LCD display a slight over-exposure, the computer monitor display measuring just exposure. This is also a part of the user always shoot bleak picture of the result.And LCD power consumption has also been the color friendly strain "were headache, so many" color friendly strain "filming or used to use the optical viewfinder, the optical viewfinder view rate is only 80%-90%, and in shooting near features also remember it but the paraxial!, of course, want to shoot spectacular images have to close one eye, with both hands of the thumb and index finger on a" frame ", the immediate scene imagination into India in books or on the wall painting ….
In short, the camera is filming the end of the process is the key before. .
4. do not superstitious DC Auto mode.
First of all, and traditional cameras, the biggest difference is that another DC has a white balance. This is somewhat similar to traditional photography in color temperature, and because the beginners do not attach importance to the white balance, and thus production of color cast. DC generally provide automatic, indoor, outdoor, manual four models, beginners are trusted AUTO, may tend to shoot the picture side of a color, as long as we carefully note the LCD viewfinder can be discerned.When we were just filming a real, the real general resolutions, if blue, DC white balance automatically to blue, then shooting other kind nature will also color. Although this point will be reflected in the LCD, but generally not found for beginners. At the same time, some models are not perfect, such as: SONY's DC in indoor mode has a status of "blue syndrome", so we still use manual white balance as possible as well. Moreover, but also closely monitor LCD color changes, a discovery that white is white, you'll have to re-add the white kind lighting correction, white balance. In addition, some digital cameras have automatic white balance function surrounded by style, in order to record accurate color information. .
Second, Aperture, shutter control. Recommended if you have manually or use manual mode, automatic mode typically takes a bleak picture, especially in the noise. Because when shooting indoors, DC will normally be automatically promoted ISO values, such as: SONY DSC-F505V indoors up to 282 in General about the speed and image quality is inversely proportional to the relationship, that is, the higher speed use equivalent, the lower the image quality. This and the characteristics of the traditional photographic materials, just like in the digital camera on this performance is even more apparent. Because traditional photography, we film by choosing a different sensitivity or through the "acceleration-sensitized" to change the shooting sensitivity, but can not be done on digital cameras, it can only improve the sensitivity of CCD gain and circuits to improve CCD speed of response, that the expense of filtering performance and resolution targets at the cost of doing so will generate a signal to noise problems, and eventually leave marks on the screen, and traditional high sensitivity this film is very similar to the coarse particles.Therefore, when using the camera, if you want to get a good image quality should, as far as possible, select a lower speed, or equivalent directly fixed to the minimum value.
Again, DC has a macro mode, and digital camera wide angle generally higher, reaching F2. .0 Around. In automatic mode, the camera's program also tend to use a larger aperture to shorten the shutter time, to prevent vibration. But common sense tells us that photography, the camera lenses of contraction from the maximum aperture of the general contraction of two photographs taken around the best. Especially in macro mode, such as: SONY DSC-S75 in the film some of the phone keys, only the middle part of the clear and detailed, all around with a slight fuzzy.We, therefore, it is best to use the aperture priority or manual mode, using a smaller aperture to expand the depth of field. If the camera is no aperture priority features, you can try to maximize the brightness of the environment, let the camera automatically select a smaller aperture or use Flash, image quality can be improved.
5, the right light, and light dialogue. .
Light is the soul of photography. Therefore we have to keep an eye on changes of the light, not just the intensity of the light, as well as the direction of light and lighting. Where the sunset to sunset: stain symbolizes Romance; Dark Sky appear out of the cold tones of grey, symbolizes the melancholy; shade removed a bunch of sunshine, happy, joyful revealed emotions ….
Resolution of light intensity. .
Hard dimming is usually issued by a single light source, such as: the Sun, spotlight, Flash or single light bulb. In this light, the subject contrast, detail and quality is outstanding. You can use this light is on.
In contrast, diffuse light produces soft light quality. Indoor indirect lighting, outdoor shade and cloudy day, all this is the case. In this light conditions and quiet outdoor portrait shot is another view of the ideal, however. .
Pay attention to the light angle.
Different point of light, texture Pi Sheti will accordingly be strengthened or weakened, the shape of Pi Sheti will be highlighted or diluted. Photo of tone is happy or sad, and also because of the angle of light vary. From above or behind the camera (often called a positive light) projected over the light will reduce the level of Pi Sheti sense, because a positive light is not conducive to high light and shadow to create. Better option is to source bias on the side, with the Pi Sheti approximately 45 ° angle into the side edge, the performance of Pi Sheti could well shape and details. .
When light from behind the subject, just shot at camera will produce backlighting. Photographed in the backlighting is dramatic. When shooting portraits, figures in the character's hair contour of marginal generating pretty light. The backlight contrast can produce a silhouette effect.
Digital camera photography. .
In the traditional photography, a is also not easy to grasp the issue of color, in the digital camera has ceased to exist, since the digital camera you can adjust the white balance, regardless of light source color temperature and negatives. This is one of the key benefits of a digital camera. While digital cameras compared to traditional photographic materials, especially new dye-photographic materials, and digital camera in latitude index has no advantage, so a precise exposure while shooting is still a good digital camera for the image quality of the basic principles. In actual use, we found the camera to the light of the requirements are higher, it is particularly important in indoor shooting . Therefore, if we are not shooting in indoor lighting outside the other, it should be possible to use flash. .
6, several mistakes.
Accustomed to using UV filters. .
For traditional photographers, one of the mirror UV is a must. But because of the light sensitivity range of DC to long wave-offset, that is to say on the red light and infrared light sensitive and blue-violet (especially UV) and insensitive. On the digital camera combined with UV lenses will not get the desired effect of enabling, and optical performance is not good UV lenses will also have a negative impact on the image. So, you don't need to UV.
Tripod is deadwood. .
Don't think that apart from a professional photographer or a photography enthusiast, crazy, Tripod for digital camera does not start. Because you want to take a clear image, photograph, you must absolutely steady the camera, even the most minor of jitter is blurring the image, but also for this result we often helpless, unable to post-production to eliminate this effect.
Of course, there are an ordinary film camera issue, but because digital cameras low light sensitivity, and the need to deal with a series of circuits, there is shutter delay problems, such as: S75's shutter delay close to 0. .1 S, fast film than the film cameras need a longer exposure time, when in low light, even more so. In order to stabilize the camera when shooting as clamping elbow and should be placed into one of the most stable parts - forehead, and gently press the Shutter. But the best way is the camera mounted on a tripod or place it on a table, desk or other object is not moving.Especially when shooting close-up and macro photography, use a tripod would get better results.
Ignore the post-processing. .
Use digital image digital camera, only very few seem to be perfect, in fact, regular film camera. Of course, the advantages of digital images is that you can later processing, but some people may think this is the loss of "fidelity" real meaning. In fact, it is still in the photography of creative ideas, using various means of digital technology, the photographic material optimization or combination of flat to the magic of creative works of art again.
As long as the appropriate use of image editing tools such as: PHOTOSHOP, etc, you can let those who do not become quite exceptional photo quality. You can highlight the image underexposed, correct color balance, crop out distracting background, it covers some minor defects (such as hot spots caused by light reflected), and even a few photos or image synthesis (see Figure) . Capable of photo editing digital camera is one of the main advantages. .
7, knowledge in the use of value--is to practice.
Not necessarily "on multi-arts cooked," but to achieve the "Arts and cooked", then need to "work more", digital photography is no exception. So, as far as possible under different light conditions more pictures. Photography, attention to records used by the camera when shooting settings and lighting conditions, then study to see which setting is best under what conditions. Professional photographers to take pictures always capture the same image several times, each time a change of camera angles or the exposure time setting, we should do.Most digital cameras have an LCD display, you can use it easily observe and delete images you don't like, so you don't have to worry about as a result of the indiscriminate shooting "are not enough storage capacity, although filming with confidence in a variety of exposure of the image, so that, ultimately, at least a good picture.
