Digital cameras like traditional cameras, to take a digital photo is a very simple thing, just press the shutter, \"click\" to complete. But it's not so easy to get a good picture. The birth of a good digital photo often needs to meet the conditions of good lighting, correct exposure, the most appropriate resolution, good framing and accurate focusing. According to the characteristics of digital cameras, in order to take good digital photos and create satisfactory digital image works, we should pay attention to the following aspects.
First, confirm the setting of camera parameters before shooting
Most digital cameras offer a variety of Settings in the Settings menu. Including image resolution, focusing mode, aperture, shutter and other items, of which the most commonly used is image resolution. Many cameras offer multiple resolution options, such as the Agfa1280, which has five Settings: 1280×960, 1024×768Hi, 1024×768, 640×480Hi, and 640×480. Most cameras have default Settings that take effect automatically when the camera is turned back on after a period of time, such as 30 minutes. Therefore, before each shooting, especially after replacing the battery, you must re-check the camera's Settings menu to confirm the resolution, aperture and other Settings, otherwise, the photo may not achieve the expected effect.
Second, try to shoot with the highest resolution
Digital cameras have a limited resolution - even high-end cameras. In mid-to-low grade digital cameras, the resolution of photos ranges from 640×480dpi to 1024×768dpi, which is very low compared to traditional cameras. In fact, most Web graphics are less than 640×480dpi. Therefore, the images taken by digital cameras are only suitable for Web browsing.
When taking digital photos, getting as much clarity as possible is a top priority. When shooting with a traditional camera, the main consideration is to take a good scene and construct a good picture. If the digital camera is going to shoot a typical photo, all the basic photography principles are applicable. But if you're just shooting a single subject, such as a watch or a phone, then framing, adding movement, and other guidelines can be ignored. At this time, the object should be as full as possible to the viewfinder frame, even if the resulting photo composition is poor, it does not matter, should be used to the maximum resolution on the subject.
In other words, if you take a picture of a person, you must include the surrounding scenery in the viewfinder frame, so that people and scenery can be balanced, and follow the composition principles of traditional photography. But in digital photography, you usually take a picture that includes the scene first, and then you process the image and crop out the excess. This means ignoring the golden rule of conventional photography and filling the frame as much as possible with the images you intend to use. For example, when taking a photo of a computer at home, only the computer should be in the viewfinder frame, and then crop it out in the picture processing software. This maximizes the resolution of the main computer.
3. Use light correctly
Most digital cameras have high lighting requirements. Before shooting, create as good light conditions as possible. Conventional film is also affected by light, but much less so than digital cameras. If the light is too strong in the range of the digital camera photo, it will produce a band effect, which is difficult to correct without a lot of careful adjustment work. On the other hand, because the CCD has a certain sensitive threshold, if the light is dark and does not reach the required minimum brightness, the digital photo will be seriously damaged. Even slightly weak lighting can significantly reduce the sharpness of the photo. Due to the limited effective distance of the flash, even if the flash is used, shadow areas or light conditions in the evening may still be underexposed for digital cameras. The use of more sensitive CCD chip is an effective way to reduce the light requirements of digital cameras. It should also be noted that certain types of light have different effects on different cameras, as does conventional photography. The point is that certain lighting conditions affect digital cameras differently than they do conventional cameras, which requires experimentation. Fluorescent lighting will produce brightness and color deviation; For best results, use a TV newslight. The test shows that in a shooting cycle, the use of tungsten lamp in the camera room for digital shooting, after the computer to observe the photo, surprised to find that when the light is directly towards the lens (rather than from behind) the photo significantly increased orange.
For low-grade digital cameras, natural light is really the best. Table lamps and camera lights can also be used, but the lighting needs to be controlled so that it is direct light, as the low resolution of the light and camera can cancel out the effort to achieve excellent and continuous tones. To maximize daylight without having to go outside to take pictures, set up a table with a background made of white poster board and place it next to a window to maximize daylight use. At present, fully or partially clouded daylight is the best light source for digital cameras.
Four, careful use of flash
Many digital cameras have a built-in flash. There are usually four Settings: flash, no flash, anti-red-eye flash and automatic flash, and the last gear is for the camera to determine if additional light is needed. In many cases, flash can ruin a perfect photo or create errors that are difficult to remove later.
For point-and-shoot digital cameras, most automatic flashes occur in cloudy weather. Turn the flash off and then increase the exposure time to get better results. The flash is not as well controlled as the exposure time, and the light from the flash tends to be reflected off nearby objects, creating uneven flares on the photo. Therefore, even when taking pictures on cloudy days or at sunset (or in other less-than-ideal lighting conditions), use the flash as little as possible. The image is processed by the CCD chip, and the infrared ray emitted by the flash will affect the image. For example, a red area may become greenish when recorded. When shooting indoors, you should provide enough lighting so that you can do without the flash, or see if you are happy with the photo without the flash. To see the difference, take two photos of the same subject, one with a flash and the other without, perhaps better. You can learn the skill of taking pictures without flash, but you need to have other light sources to fill in the light.
Five, color temperature adjustment
Friends familiar with traditional photography know that color film has daylight type and light type, the purpose is to apply to different light source environment, daylight color temperature is 5000K, halogen quartz lamp color temperature is 3200K.
Digital cameras can not change the film, so the use of white balance adjustment, while breaking up and automatic, manual adjustment has flexibility, can create unexpected artistic effects, but manual adjustment is not so simple, it is difficult to master. Automatic adjustment can ensure that the shooting effect will not deviate greatly, but it is difficult to create special artistic effects, such as the use of daylight film shooting, with 3200K quartz lamp as a light source, you can create a warm atmosphere, yellow color in red, is now a very common method of wedding photography, shooting with digital cameras, using white balance automatic adjustment, The result is not as obvious as a traditional camera, but it is still good. There are also the same lighting, the same position of the model, the result of using a different color background shooting, the model's skin color will be different. Different digital cameras have great differences in shooting, so for the adjustment of white balance, we must test for different photographic environments, so that we have a good idea.
Download the photos to your computer, adjust and save them
Digital cameras generally have liquid crystal displays (LCDS), most of which are backlit, and the photos displayed on it are likely to look much better than those displayed on a computer, especially in color-saturated and bright areas. LCD is best used only for image positioning, such as browsing to view images or establishing image indexes, in short, it is suitable for simple viewing. It is worth reminding that the image effect on the LCD display does not represent the final photo effect. The sketch does not fully reflect the reality of the generated photo. Also, photos that don't look good in the context of a sketch are likely to have some part that is interesting or useful. Before deleting a photo, download the image entirely from the camera to the hard drive and observe it from the computer screen before deciding whether to delete it. The captured image is downloaded to the computer, and the corresponding operation can be carried out according to the different software brought by the camera. In general, most download software displays a series of sketches representing the images saved in the camera, from which you can select the photos you want to download from the camera. After opening a set of images with the camera, you can either modify them and save them later, or you can save them as they are and modify them later. Many downloadable software programs can modify photos, but not all packages provide suitable modification options. So downloading and saving the image as it is, and then modifying it, should be the best way.
7. Retouching the original image
Look at the images first, do a visual examination of each image, and maybe write some annotations. Is the image too big, too dark, too bright or too blurry? After the faults are picked out, image processing software is used to improve the final image effect, correcting one problem at a time. Of course, not every photo requires this much work. However, almost every photo requires targeted adjustments. You can try many things until you get a satisfactory image, and then save it.
The adjustment of digital images requires a good command of image processing software, such as Photoshop, UleadImpact, Photo-Deluxe, etc. Then consider what to do further. For example, don't use Settings that have a wide range of effects and don't change them too much; Only make small gradual changes at a time, preview the effect first, slowly achieve the best effect, and then decide to save.
8. Digital creative applications
When using film photography, the photos are developed and placed directly in a frame, an album or as a slide film. The real joy of digital photography lies in the secondary processing of digital photographs. Digital photography is different from film photography in that the use of digital photography can change the image and provide new ways to utilize the image. Digital photography can be transformed, combined, shaded, lit, collaged, and other manipulations. These features are the beauty of buying a digital camera.
When taking pictures with a digital camera, give full consideration to achieving the effect you want to create. For example, if you want to create a simple photo with a prominent subject, pay attention to all aspects of the frame. However, if you want to create an interesting photo puzzle or crop the subject, then you should fill the viewfinder frame with the image you want to take, no matter how bad the photo itself looks. For example, to create a printlike art image, it is necessary to maximize the photo in order to extract the line drawing from it. The fact is that the combination of digital cameras and image processing creates so many interesting possibilities that you should learn how to create the best harmony between the photos you want to take and the final results you want to achieve.
Nine, photo printing skills
Digital cameras ultimately rely on printers to complete the whole process. At present, as far as Photo printers are concerned, the possibility of using thermal sublimation printers is very small, while color inkjet printers account for the vast majority. As far as photo printing quality is concerned, photo quality printers should be selected. Printing paper preferred photo quality Glossy paper and photo paper, print quality and ordinary inkjet paper is worlds apart. There are 1440dpi and 720dpi resolution print quality can be easily distinguished by the naked eye, if you pay attention to quality, you should still choose 1440dpi printing, although the cost is longer printing time and more ink consumption. If you want to print out a perfect photo, you can cold mount the inkjet print photo, cold mounting film selection of the middle of the thin model, the final work and the same size color photos are hard to tell.
10. Carry spare accessories
Digital cameras are particularly power-hungry, especially after turning on the \"electric tiger\" LCD display. It is recommended to use a 1300mAH Ni-MH or Li-ion rechargeable battery as an extended power supply. When shooting outdoors, because AC power can not be used, it is necessary to bring a fully charged backup battery. When shooting indoors, use AC power as much as possible, but you must make sure that the output voltage of the power supply is exactly the same as that required by the digital camera. In use, it was found that the AC power supply of some cameras can be common with digital cameras, such as the Panasonic series of \"Palmtop\" camera power supply can be used directly for Agfa, Epson and Casio digital cameras.
In addition, you should also prepare a certain number of storage cards, so as not to have enough storage space during the shooting process and miss the wonderful shots.
Nowadays, people's living standard is getting higher and higher, and the work pressure is also increasing. Travel and outdoor activities are also increasing. Photography is a hobby of many people. I'm here to talk about how to carry a camera.
First, the camera is a fear of humidity, fear of high temperature and fear of dust, we must use a special camera bag for outdoor photography. This will protect the camera better.
Second, when using, the correct way is to hang the camera belt on the shoulder to prevent the camera from falling.
Third, when using tripod shooting, be sure to fix the screw firmware, need to move a short distance wrist buckle the camera belt, in case the camera and tripod fall apart.
Fourth, cover the lens cover with good back, waterproof gas, anti-dust. The camera is afraid of collision, and you must be careful when you go out.
The perfect camera takes the perfect photo. Have a nice trip!
It is best to take the camera bag, so that it can better protect the camera, if you can hang the camera in the chest for easy use, but the shaking will be relatively large, it is recommended to cross the shoulder, so as to reduce the shaking, better protect the camera. No matter what, always have a lens cap to avoid blurring or bumping the lens.
