Investigated power situation.
Power check is to verify important properties of the key advantages and disadvantages of the device and the machine an effective method, this step is essential. Power check is: the machine was switched on for two standard power supply (AC adapter or a dedicated battery fully charged), with a good monitor, do not open the lens cover, so that the machine power for 5 minutes to warm up.
This will not only make the machine's electronic circuits and mechanical parts from the "cold" state - factory incentives up, then check to ensure that the exact results can be stable, and give the machine a dedicated fast charging small batteries, so that all files automatically memory control data can be stored for long periods.
Second, check the viewfinder.
There are currently viewing the camera LCD screen and optical viewfinder are two framing. Both the LCD viewfinder or optical viewfinder, check the methods are limited to visual inspection and power check two. Mainly to see whether the flawed appearance, such as cracks,
jvc bn-vf808 battery scratches, and so on. Check the main power to see image clarity, color fidelity, optical viewfinder parallax size, these checks are more intuitive, easy to identify strengths and weaknesses.
Three examinations zoom function.
Camera zoom functionality into optical zoom and digital zoom. Check the monitor was switched on when the zoom, lens at about 3 meters away from a fixed target, the image tune with a real manual focus. Then the zoom switch from T (telephoto focal length of the longest) to W (wide-angle, short focal length) alternating press several times, then they should have heard subtle light of the "squeak ... ..." a continuous sound of mechanical operation.
Monitor screen while the target image should be uniform from large to small, steady changes in ascending
Kodak klic-8000 battery. If the mechanical operation of the sound does not lag, rolling Dayton, monitor screen does not jump, and flutter from happening, it indicates good performance.
Four examinations camera device.
Check the camera device can be connected to the large screen monitor, take a white paper, on a closer look at the monitor screen compensation effect, the location to see if there is a fixed black spots. Black spots appear that indicates a failure of bad pixels and compensation, should be selected not see the defects of the machine. High-end camera either analog or digital machines with three CCD. 3CCD models with high resolution and vivid color reproduction, but the optical structure is complex, expensive. Single-chip CCD color filter directly to the matrix produced in the CCD chip, simple structure, good reliability.
Five check white balance.
White balance adjustment is usually divided into two kinds of automatic and manual mode. Check the manual white balance adjustment, the white machine-Original lens hood lens cap, open auto iris, focus changes to a minimum, manual focusing transferred to infinity
canon powershot sd750 battery inside the school color film set to "outside" (0UTDOOR), marked stalls or the sun, and then the camera on to the sky, but do not directly point to the sun.
Then click the White Balance button, the viewfinder "W" off after a few flashes, indicating that the white balance has been adjusted. At this point the monitor screen should show an "ideal" white; check the auto white balance, white balance switch to the first "automatic" (AUTO) file, and then were in the room (natural light) and outdoor (sunlight) with a shooting White, attention to the screen fills the screen and adjust the real, observed and compared the effects of the two shot. If the same effect twice, and the white ideal, then the automatic white balance performance is normal.
