Why is there a ghost when the flash of a digital camera is on?

With the popularity of digital cameras, many ordinary consumers have digital cameras and have experienced the happiness of digital photography. When we take pictures with digital cameras, we often encounter problems of one kind or another, which leads to the failure of shooting. After all, electronic things feel more complicated than mechanical ones. The following are the causes and solutions of these problems:

First of all, the captured image is not clear.

1. Although the highest resolution is used and the light is good, the photos taken are very blurred. This situation is usually caused by camera shake when the shutter button is pressed. Because of the low sensitivity of digital camera, it takes a long time to take pictures with digital camera. To take the clearest picture, you must hold the camera steady, even the slightest shaking will cause the image to blur. Solution: Hold the camera steady, use a tripod when taking pictures, or put the camera on a table, counter or other fixed objects. Then there is the word "practice", usually practicing the basic skills of holding the machine.

2. The autofocus mark of the viewfinder is not placed on the subject. Place the autofocus frame on the subject, or use the focus lock function.

3. The lens is dirty. A dirty lens will make it difficult for the camera to find the field of vision and blur the image. Clean the lens with special lens cleaning paper.

4. Improper mode selection. When the standard mode is selected, the photographed object is shorter than the minimum effective distance (0.6m) of the lens. Or when the close-up mode is selected, the subject is far away from the minimum effective distance. When the subject is in the range of 0.3-0.6M, take photos in close-up mode. Outside this range, take pictures in standard mode.

5. In selfie mode, stand in front of the camera and press the shutter release button. You should look at the viewfinder and press the shutter button. Don't stand in front of the camera and press the shutter button.

6. Use the fast focus function in the incorrect focus range. Use the correct fast focus key for visual distance.

Second, the image is too dark.

1. The flash is blocked by a finger. Hold the camera correctly and don't let your fingers block the flash.

2. Press the shutter release button before charging the flash. Wait until the orange light stops flashing.

3. Don't use flash. Press the flash assist lever to set the flash.

4. The subject is placed outside the effective range of the flash, and the subject is placed within the effective range of the flash.

5. The main body is too small and backlit. Set the flash in auxiliary flash mode or use fixed-point metering mode.

Third, the image is too bright.

1. The flash is set in the auxiliary flash mode. Set the flash mode to a mode other than the auxiliary flash.

This photo is very bright. Adjust exposure.

Fourth, the color of the image taken indoors is unnatural.

The reason is that lighting equipment affects the image. At this time, the flash mode is set to the auxiliary flash mode.

Fifth, the image contour is blurred.

The reason is that the finger or belt partially blocks the lens. Hold the camera correctly, and don't let your fingers or tape block the lens.

Six, the flash is not bright

1. Flash is not set. Press the flash eject lever to set the flash.

2. The flash is charging. Wait until the orange light stops flashing.

3. The photo is very bright. Use the auxiliary flash mode.

4. When the flash has been set, the flash works abnormally when the indicator light on the control panel lights up. Please repair it.

Seven, the camera does not move

1. The power is not turned on. Press the power button to turn on the power.

2. The battery polarity is wrong. Install the battery correctly.

3. The battery is dead. Update the battery.

4. The battery is temporarily out of order. Please keep the battery warm when using; In the process of taking pictures, the battery is temporarily not used.

5. The card cover has been opened. Close the card cover.

Eight, the camera automatically turned off

1. If the digital camera suddenly shuts down automatically, your first thought should be that the battery is low-digital cameras are big consumers of electricity and often shut down because of the low battery. Replace the battery.

2. If the digital camera still can't be turned on after replacing the battery, you find that the camera is hot, because you have been using the camera continuously for too long, which leads to the camera overheating and automatic shutdown. Stop using it and wait for it to cool.

Nine, press the shutter button can't take pictures.

1. The photo just taken is being written into the memory card. At this time, release the shutter key until the indicator light stops flashing and the LCD screen disappears.

2. The memory card is full. Replace the memory card, delete unnecessary photos or transfer all photo data to a personal computer and delete them.

3. The battery is exhausted when taking photos or writing to the memory card. Update the battery and take a new photo.

4. The subject is not in the effective working range of the camera or it is difficult to lock it by automatic acquisition. Refer to the effective working range of standard mode and close-up mode or refer to the autofocus section.

X. the camera can't recognize the memory card.

1. uses a memory card that is incompatible with a digital camera. Different digital cameras use different memory cards. In most digital cameras, multiple memory cards cannot be used. The solution is to replace your digital camera with all the memory cards.

2. If the memory card chip is damaged, find a manufacturer to replace the memory card.

3. The image file in the memory card is damaged. The reason for this phenomenon is that the memory card is taken out when shooting, or the digital camera is suddenly turned off because of serious power shortage. If the problem persists after reinserting or reconnecting the memory card, please format the memory card.

Eleven, just take photos can't be presented on the LCD screen.

1. Power off or recording mode on. Put the record/play switch in the play position and turn on the power.

There are no photos on the memory card. Check the control panel.

Twelve, the LCD screen is blurred.

1. The brightness setting is incorrect. In playback mode, select the intensity from the menu and adjust it.

2. The sunlight shines on the display screen. Cover the sun with your hands, etc.

Thirteen, the camera connected to the computer sends data to the computer when there is an error message.

1. The computer is not inserted correctly, and the cable is inserted correctly.

2. The power is not turned on. Press the power button to turn on the power.

3. The battery is dead. Update the battery (charge) or use the AC power adapter.

5. Improper selection of image transmission speed. Select the correct transmission speed on the computer.

Fourteen, there are many points in the photos taken.

This is what we call noise in photos. This situation often occurs in the shooting of night scenes, which is caused by high sensitivity. The higher the sensitivity value, the rougher the image quality, the lower the sensitivity value and the finer the picture. But high sensitivity means high sensitivity to light, so we often choose high sensitivity when shooting in low light. Then, if the noise reduction system of the camera itself is not good, it will cause noise on the canvas. To avoid this situation, we need to artificially reduce the sensitivity, and then use a relatively long exposure time to compensate for the entry of light, so that the photos will have a sense of layering and the quality will be guaranteed. Of course, the premise is that you need to bring a tripod.

Fifteen, the photo is dark and granular images appear.

Although the highest resolution is used, the photos are very dark and grainy images appear, which is usually caused by insufficient light. When taking photos with a digital camera, the light has the greatest influence on the photos. The sensitivity of most digital cameras is equivalent to SIO 100 film. Therefore, insufficient light will lead to the darkening of photos and the appearance of granular images. If the camera has a flash, it can be used not only for indoor photography, but also for outdoor photography of objects in the shadows.
