Control exposure
Whether traditional or digital camera, camera, shooting pictures affect the control effect of exposure are critical. To control the exposure, we must first remember that the shutter speed, aperture and ISO sensitivity between the three, that the shutter speed to double the amount of light through the lens will be reduced by half; aperture for each additional file, and shutter speed doubled when the same amount of light will be reduced by half; battery for pavilion zv5000 ISO sensitivity to double the amount of light through even half the amount of exposure can also use the same exposure.
Today, most digital cameras are equipped with the “exposure compensation” function, set the exposure compensation set to +1 files, it means that the shutter speed slows down by half, or doubling the aperture. In fact, using a digital camera to provide the default mode, the camera aperture and shutter speed from the two aspects of regulation, so that the amount of light through double.
Under normal circumstances, can the entire picture from the OLYMPUS blm-1 battery camera to measure light intensity, and determine the best exposure. However, the smart camera is limited, such as shooting in white snow and other objects, the camera itself will mistakenly believe that an adequate amount of light, and automatically reduce the exposure, so captured images on the dark. The large black object shooting, the camera will also think that enough light.
To control the exposure, you need to have knowledge of exposure compensation, so as to capture the brightness and brightness as desired inspiron 1545 battery photos. Under what circumstances, what the most appropriate level of compensation, and ultimately it is up to your own eyes to master. There can not give you a precise standard, but the principle is that, for many white and bright areas of objects should increase the exposure compensation, black and dark, wide area of ??the object, should reduce the exposure compensation.
Infrared film effect
In addition to the general flash, the other light used in photography can be technically, for example, infrared and ultraviolet. Infrared photography, whether amateur or professional in the field, there are a lot of discussion and application. Want to experience, you can apply when shooting high-power infrared light body, you can also upload other electronic devices emitting an infrared filter, so that the infrared will directly hit the main body and then reflected back to the KODAK CR-V3 Battery camera image, so that you can achieve infrared shooting. However, traditional film photography to rely on special infrared, and film preservation, washing and shipping are a hassle, so users are more general lack of experience in this area. However, because silicon material digital camera sensor sensitive to infrared wavelengths, infrared photos than traditional film camera simple.
In addition, if your digital camera with infrared auxiliary functions, such as the SONY F717, then the application of infrared photography, not only can continue to operate under low-light environment ecology photo shoot, and will apply it on a landscape photography can be created with public different special effects, and also can pivot function, but the infrared capabilities perspective is not 100%.
Rational use of flash
Flash is a very convenient and suitable as a supplementary source of a tool. But in general, HP PAVILION ZV6000 battery emphasizing automation of digital cameras and flash is not too strong, at best, be programmed to flash function, to provide “automatic”, “mandatory”, “red-eye reduction,” “slow” and other settings.
“Automatic” mode, the camera automatically determine the shooting scene lighting is adequate. If less, it will automatically open the flash when shooting flash to compensate for the light; “red-eye reduction” mode to let the flash flashes rapidly once or several times, makes the pupil to adapt to, and then to the main flash and shooting, to avoid photo the problem of human eye redness; “force” mode that is either in bright or low light environment, both the flash to flash, usually taken back to the light source used in person; “slow” mode digital camera shutter delay release rate, the prospect of flash lighting, with a slow shutter speed such as 1 / 5 seconds for the low light background exposure can be taken out of the foreground and background are harmonious exposures.
As digital cameras have limited intelligence, in different settings, MOTOROLA GP340 battery flash the effect is difficult to determine, therefore, to better capture the effect, you need to buy an external flash with manual functions of a digital camera, flash through the brain decide strength, size, number and frequency, can greatly increase the scope of photography. General, manual control flash needs a lot of practice, since the use of a digital camera, so you can more than a few test shots to determine the flash of energy. Note that some external flash to reduce the use of low-power light output, color temperature will be slightly higher.
Understand the difference between the computer screen
Using a digital camera users will mostly use the computer for photo processing, or stored on a computer, browse photos. At the same time, due to view photos on the computer screen the effect of the photo and the actual output is not the same effect also caused trouble plagued the majority of users.
In fact, due to the different Acer travelmate 240 battery equipment to produce such a difference is very normal, you feel the image presented on a computer printer output than the photo beautiful? Display resolution is only 72dpi, but showing the image than the results of 720dpi or 1440dpi printer, even better, the reason is that the color on a computer screen output in analog form, when the continuous-tone image can display, even if the resolution not very high, the image is still vivid. But with the ink-jet or laser printer output, the image is composed of ink dots. Printer can only control whether the dots, they can not control the depth of change. And the resolution of the printing and electronic images using a resolution different from the current technology to make the same precise ink drop printer to print is very difficult.
In addition, there are many similar problems, for example, digital camera photo effects in normal, but watch the computer screen Shique a little exposure is not normal, this is because the camera’s LCD display and cathode ray-type display of the differences caused and the same problem with the printer is quite normal.
So how to solve these problems? To solve the printer problem, you first need to adjust your computer screen color to display color printer can be consistent with, and learn to calculate the print output quality images require different accuracy (refer to the above described “shooting Resolution choice “). The problem of digital cameras, liquid crystal display is relatively simple, you only need to use Photoshop to open images using “Image” menu “adjustment” in the “Levels” look, if the average gradation, then replacement A1189 battery photo exposed properly, it should adjust the display brightness If the color scale on the right blank area, then the photo is underexposed, you can have a basis to make adjustments.
Exif Photo Information Protection
Most digital cameras support the Exif photography photo store information, such photographic information can help us to easily save shooting data, to enjoy digital photos, either the feeling of shooting memorable, but also allows us to sum up shooting experience, improve Photography level. Digital photo photography by reading the information, more photos of the same subject using different shutter, aperture and other camera settings and processing, we can better grasp the best time to shoot photo camera settings to improve their photography level.
Exif information is very useful, but can easily be destroyed. If you use Windows XP image file viewing feature to browse your digital photos, photo photography information will be destroyed. Photography information will be destroyed, and these photographic information is damaged can not be restored.
In addition, most computer users prefer to use general-purpose image viewing software (such as ACDSee) to view digital photos, but you need to pay special attention to is that if you use ACDSee rotate photos or change the resolution of digital photos, digital photographers Information will also be changed so that the choice and use digital photo management software, you need special care. If your HP Compaq NC6120 battery digital camera manufacturers bundled digital photo processing and browsing software, you should first select them, such as digital camera Canon ZoomBrowser EX, PhotoStitch and other bundled software.
