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.

How to store digital camera

Comments Off

Period of time without a digital camera cases, camera batteries should be removed, and the camera on the camera bag, on the ventilated, dry place. Digital camera for a long life, but every different specific. For example, Canon’s 30D’s shutter times the official data to support 10W pressing, as whole is hard to say, I have the Ministry of DC, spent 6 years, you can continue to use …

As with traditional photography, digital cameras also waterproof, dustproof, shockproof and so on, for routine maintenance of knowledge must be understood, and OLYMPUS li-42b battery maintenance and conservation of such cameras to give sufficient attention.

(1) strictly in accordance with manual operation
Digital cameras sophisticated equipment, complex operation. Therefore, we must operate in strict accordance with the instructions of the steps, or vulnerable to failures and crashes and so on.
(2) to protect the memory card
Digital camera memory cards are very small and thin, easily broken, based on the interface piece of metal contamination and scratches easily, so the safest way is to talk about specific memory card into the box and inside the camera. Usually some talk about a memory card stored in a dry environment, there are image files have also to try to avoid the magnetic card and avoid high-temperature storage.
(3) to protect LCD screen
Digital cameras usually have LCD screen, in use, may be difficult to wipe away some of the fingerprints glue or other dirt, in addition to software and lightly cracking, the available transparent stickers on the LCD screen so the screen is scratches and affect the image observation.
(4) power operation when connected to a computer
In the digital camera images will be downloaded to your computer, you need a digital camera and computer connected with a wire. Must be shut down before connecting the computer and digital camera, so as not to damage the live operation of the digital camera.
(5) put the camera bag
First, you need a sturdy, easy to install camera, camera bag, digital memory card, battery pack, and then also need to assist some of the luxury or a small portable HP 360136-001 battery camera tripod.
A leading manufacturer of camera bags, such as Tamrac, Lowepro and Domke use high quality raw materials, better shock protection and an excellent strap and metal hardware. Reduce the size of these devices are more suitable to place a digital camera.
If you want to buy a new camera bag, it is best to find slightly larger. If you buy a camera bag to take something every time, when all things must be put out there, you certainly would not like it, because then miss a lot of good photo opportunities, but also annoying. The best time to buy a camera bag and accessories to bring the camera to see what kind of camera bag is best for you.
Also very particular about how the bag back. Adjust the camera bag on the belt, do not make the camera too far away from your body, otherwise it will bounce from your body, hit someone or hit other objects. The best approach is to hang the camera bag slightly higher, so you can prevent it by the collision of arms, but also to prevent the thief.
(6) Keep the camera clean and
Stains on the lens would seriously reduce image quality, there spots or reduce the image contrast. The fingers touch the lens, which is inevitable, dust and grit will fall to the optical device.

That is why we need to clean the camera causes. Cleaning tool is very simple: the lens paper or cloth with fine tools, NIKON EN-EL10 Battery lens brush and cleaning kit. Do not use cardboard, paper towel or napkin to clean the lens. These products contain a cut of the wood pulp friction, it will seriously damage the delicate coating on the camera lens.

When not in use cleaning paper, the micro-fiber cleaning cloth on the original container to keep clean. Micro-fiber cloth is washable, can be washed with regular clothes. Do not use cotton T-shirts or other fibers, as may be infiltrated to coarse. Clear lens dust Another way is to always use the lens. If your camera has a lens cover, you can use a tape, rubber bands, or “lens fixed” devices to secure it on the battery shop camera body.

Hot and cold weather will also affect the camera. If the camera original in the air-conditioned room, and then immediately placed in a relatively hot, humid environment, the lens and viewfinder will have a cloud point appears. Then need to use the appropriate tissue or cloth to clean. If you take the camera from the cold, dry outdoors into the room, the best camera in a bag inside the first warm-click, and then out on the house. And be careful lens to see if it is not “sweating”, if immediately wipe sweat.

Professional photographers, a proposal is very simple, maybe you will not believe: carrying a plastic zip lock MOTOROLA HNN9008A Battery bag. In very humid or dusty climates, you can dig a small hole in the side of the camera lens just let go and then put the camera bag, not to fog, moisture and dust to enter, will extend its life.

1. While the use of the highest resolution, the light is good, but taken out of the picture blurred. This usually is due to press the shutter release button is caused by camera shake. Because of low sensitivity digital camera, so using a digital camera to take pictures, you need to hold the camera for longer. To take the clearest pictures, the camera must hold the camera steady, even the slightest shake will result in blurred images. Approach: predict with confidence the camera, camera tripod is best, or the camera on the table, counter or the security fixed object. There is also a “practice” word, usually to practice basic MOTOROLA NTN5521 Battery skills support machine.
2. Autofocus viewfinder camera signs are not placed on the property. Box will automatically focus on objects located in the camera or use focus lock function.
3. Lens is dirty. Dirty lens will cause difficulties in leaving the camera viewfinder to shoot images blurred. With special lens paper to clean the lens clean.
4. Mode inappropriate. Select standard mode, the camera lens object distance is shorter than the minimum effective distance (0.6m). Or select the macro mode, the camera is far to the minimum effective range of materials. When the subject in the 0.3 – 0.6M range, use macro mode pictures. Outside this range, use the standard model photographs.
5. In the self-timer mode, standing at the front of the camera shutter release button. Should be looking at the viewfinder by pressing shutter release button, do not stand before the camera, press the shutter release button.
6. In the context of the incorrect focus function using the HP elitebook 8530p battery fast focus. As fast focus away from the correct key.

Digital Camera Knowledge – Exposure Compensation

Comments Off

Exposure Control Exposure Compensation is a way, the general common around the ± 2-3EV divided into positive (+) compensation and negative (-) compensation of two, the camera with “+/-” symbols. In short, the backlit photography, with the positive (+) compensation (or dark in the viewfinder than the standard for the meter) to properly show the details of the subject, blur the background, access to high-profile photo; with negative (-) compensation (or in the viewfinder brighter at the metering standards) were given a silhouette effect, access to low-key picture, showing the relationship between light and shadow. If the ambient light is dim, you can increase the exposure value (such as adjusted to +1 EV, +2 EV) to highlight the clarity of the screen.

Dell XPS M1530 battery Digital camera in the process, if you press half shutter, the LCD screen will display and map the final result is almost the picture, focus, exposure, everything started. This time of exposure, it is the final image exposure. Picture bright or dim if the apparent bias, indicating that the camera’s automatic metering accuracy with large deviation, to force exposure compensation, but sometimes, shooting the brightness and the results have some access to the actual shooting. Digital camera can view images immediately after shooting, this time, you can take out a more accurate picture to see the brightness level will not differ. If the shooting was the result of partial bright or dim, they have re-shot, forced exposure compensation.

Shooting environment is dark, and the need to increase the brightness, and flash can not work, it can compensate the exposure, due to increase exposure. When exposure compensation, if the photo is too dark, to increase the EV value, EV value of 1.0 for each additional, equivalent to doubling the amount of light exposure, if the picture is too bright, to reduce the EV value, EV values decreased 1.0 per , equivalent to double the intake decreases the amount of light. Intervals according to different EN-EL14 battery camera can compensate for 1 / 2 (0.5) or 1 / 3 (0.3) unit to adjust.

White object being photographed in the photo appears to be gray or white is not enough time to increase exposure, simply means “White has become increasingly more”, which seems to exposure is contrary to basic principles and habits, and it is not true, This is because the camera’s metering is often the center of the main emphasis, the Dell Inspiron 1520 battery camera will white the main mistake is very bright environment, and thus lack of exposure, which is the most common problem for beginners easy to commit.

White clothes on white background, the camera shot in order not to judge too bright and to determine the exposure, such as a whole was very dark. Then, add a little compensation, white clothes are white, face brightness accurate.

Black clothes in the dark background, the inspiron 1525 Battery camera is judged to be dark places, the result is very white face shot. Then drop your compensation, black clothes, more black, the brightness of the face just right.

Since the camera’s shutter speed or aperture size is limited, so do not always achieve 2EV adjustment range, so exposure compensation is not a panacea, in the environment is too dark may still be underexposed, this time with the flash or increase to be considered the camera’s ISO sensitivity to increase the screen brightness light-sensitive.

Almost all of the digital camera’s exposure compensation range is the same, can be plus or minus 2EV in addition, subtraction, but subtraction is not continuous, but in 1/2EV or 1/3EV interval leaps and bounds. Such as the early old Kodak DC215 digital camera is to 1/2EV for the interval, so there is -2.0, -1.5, -1, -0.5 and +0.5, +1, +1.5, +2 a total of eight grades, and the present the mainstream of the digital camera sub-file to be more carefully, the interval is 1/3EV, and so there is -2.0, -1.7, -1, -1.0, -0.7, -0.3 and +0.3, +0.7, +1.0, +1.3, +1.7, +2.0 and so a total of 12 levels of sony np-ft1 battery compensation values.

In general, the smaller the scene brightness and contrast, more accurate exposure, and vice versa deviation increase. The camera high and low grade, high quality, and metering is more accurate, lower the deviation will also increase. If a traditional camera, film is a relatively large degree of tolerance, and exposure within a certain range the deviation is not a big problem, but the CCD camera is relatively small tolerance, a slight deviation of the exposure may affect the overall results.

In summary, exposure compensation adjustment is experience and sensitivity to color is determined, the user must be more to compare picture quality under exposure compensation, sharpness, CANON eos-300d Battery noise reduction degree and the size, can shoot the best pictures.
