Where is the camera flash?

1. The key switch with flash in the figure is a key switch with lightning sign. Tap the flash and it will pop up automatically.

Second, if you press the flash switch, the flash is still off, because the flash card slot is aging due to long-term idleness. You can pick up the reed of the flash card slot with a pen or a needle, and then touch the ON key of the flash.

Note: When the flash cannot be turned on, do not forcibly break the flip of the flash.

1, three digital photo formats

The three storage formats of digital cameras are raw, tiff and jpeg.

2. Correct use of RAW format

In order to use this image format, special image processing tool software is needed.

3. Recover the digital photos deleted by mistake.

Digital photos on the memory card can be restored like photos copied to the computer.

4. The influence of resolution when shooting.

High resolution can get high-precision images, but digital photos should be recorded in the form of image files. With the improvement of resolution, the number of image files will increase, and the time for digital cameras to process images will also increase.

5, the choice of resolution when shooting

The purpose of shooting images is the main reason that affects the shooting resolution.

6. Print size and shooting parameters

For digital photos with the resolution of 1600× 1200, the appropriate size of printed photos is calculated to be 6 inches by the calculation method of 1600÷250=6.4, and then you can multiply 6 by 250 to get1600×/.

7, the use of white balance

The ability of predefined white balance and automatic white balance is also limited. When using automatic white balance, the color of the previous scene is particularly biased towards a certain color, which causes the problem that the subsequent photos are biased towards a certain color.

8, the choice of measurement method

The advantage of measuring light through the lens is that it can directly reflect the size of the scene light, that is, the light is projected onto the photosensitive element through the lens, and then the photosensitive element transmits the light signal to the processing chip of the digital camera for analysis.

9. Sensitivity setting

ISO (International Organization for Standards) is the abbreviation of International Organization for Standards. In the industry standard of film camera, ISO standard measures the sensitivity of film to light. The lower the value, the lower the exposure sensitivity of the film.

10, shutter control skills

Common shutter speeds are:111/21/81/051/301/60 65433. The slow shutter has 1 second, 2 seconds, 4 seconds or even longer.

1 1, control the exposure.

To control exposure, we must first remember the relationship among shutter speed, aperture and sensitivity.

12, infrared shooting effect

Because the sensitive element of silicon is sensitive to infrared wavelength, it is easier to take infrared photos than traditional cameras.

13, rational use of flash

Flash is very convenient and suitable as a tool to supplement light source. But generally speaking, digital cameras that emphasize automation do not have a strong flash. At most, they program the flash function and provide settings such as "automatic", "forced", "red-eye prevention" and "slow".

14, to understand the differences of computer screens.

First, you need to adjust the color of the computer screen so that the displayed color is consistent with the color of the printer. At the same time, you need to learn how to calculate the accuracy required to print and output images of different quality (see "Selection of resolution when shooting" above).

15, protect Exif photographic information.

Exif information is very useful, but it is also easy to be destroyed. If you use the image file viewing function of Windows XP to browse digital photos, the photo information will be destroyed. Photo information will be destroyed, and once destroyed, it cannot be recovered.
