Some common problems of beginners in photography.

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 hold the camera when taking pictures. 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 an object fixed by it. Another word is "practice", practice the basic skills of holding a camera.

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 subject is shorter than the minimum effective distance (0.6m) of the lens. Or when the macro mode is selected, the subject is far away from the minimum effective distance.

When the subject is in the range of 0.0 1-0.6m, take photos with close-range macro or manual focusing mode. Outside this range, please take photos in standard mode.

5. In selfie mode, stand in front of the camera and press the shutter button. Look at the viewfinder and press the shutter button. Don't press the shutter button when standing in front of the camera.

6. Use the fast focus function in the incorrect focus range. Use the correct fast focus key according to the 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. Put the main body outside the effective range of the flash, and put the main body 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 to the auxiliary flash mode. The flash mode is set 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. After the flash is set, if the indicator light on the control panel lights up, the flash works abnormally. 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. Replace the battery.

4. The battery is temporarily invalid. Please keep the battery warm when using; Don't use the battery for the time being between photos.

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 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 until it cools down.

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 green indicator light stops flashing and the LCD screen disappears.

2. The memory card is full. Replace the memory card, delete unnecessary photos or delete all photos after sending them to a personal computer.

3. The battery runs out when taking photos or writing memory cards. 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. Use a memory card that is incompatible with digital cameras, and different digital cameras use different memory cards. You can't use more than one memory card in most digital cameras. 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 the memory card or reconnecting the power supply, please format the memory card.

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

1. Power off or recording mode on. Set the record/play switch to 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 brightness 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 or use an AC power adapter.

4. Improper serial port selection. Use the operating system software to confirm whether the serial port selection is correct.

5. No serial port is available. Make the serial port available according to the instructions of the personal computer (AppleTalk/LocalTalk function of Macintosh switch only).

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

7. TWAIN/ plugin is not installed. Install TWAIN/ plug-in on the computer.

When you can't press any key, please press the reset button on the card cover, and then press the power button.

Fourteen, LCD can't display the current state normally after power-on.

Under normal circumstances, the LCD should be able to display the current status normally after being turned on, and the display can respond accordingly with the change of function setting and shooting. If the LCD can't display the current status normally after booting, it is mostly caused by poor battery contact or insufficient battery power. You can reinstall the battery or replace it with a new one. When replacing a new battery, be careful not to confuse the old one with the new one.

Fifteen, the LCD display image has obvious defects or black screen.

After power-on, the LCD can display the current status and function settings normally, but it can't display the image normally, with obvious defects or black screen. This situation is mostly caused by the defect or damage of CCD image sensor. At this time, the CCD image sensor should be replaced. This situation often happens in second-hand digital cameras. When buying a second-hand digital camera, you must carefully identify the CCD image sensor. If the camera has no LCD screen, it is generally impossible to directly judge the quality of CCD imaging devices. Sometimes, because the CCD is damaged when shooting, everything is normal, and the photos don't turn black completely until the computer downloads them, so we can only check the quality of the output photos through real shooting.

Sixteen, the computer can't download photos normally.

In this case, there is something wrong with the computer cable. According to the camera interface, there are many ways to connect the computer, including three commonly used standard serial port connections and other connections such as USB. When connecting, it must be in place and not loose. If possible, it is best to have a spare connection, so that if there is a problem with the connection, it can be replaced in time.

Seventeen, the photo color is wrong.

We often find that the color of the scenery in digital photos has changed compared with the original scenery we see with our eyes. Sometimes it is red, sometimes it is yellow. What's going on here? This is mainly caused by poor white balance adjustment. The function of white balance adjustment is similar to adding color temperature conversion filter in traditional camera color photography, with the purpose of achieving accurate color restoration, except that the color temperature of digital camera does not need to add filter on the lens, but adopts the way of circuit adjustment to change the mixing ratio of the three primary colors of red, green and blue through electronic circuits, and correct more color components in light. The white balance adjustment of most digital cameras has a self-checking mode, which is generally represented by the symbols of the rectangular square above and the two small triangles below. The white balance adjustment in this mode allows you to aim the camera at the white object in the shooting scene, and then press the shutter halfway. At this time, the camera will automatically record the white state in this light. According to this value, the color can be correctly restored in the next shooting. I suggest you use it when the camera has this white balance adjustment mode. This function is more accurate in general, but it is hard to say when shooting under some complicated conditions. In fact, the environmental conditions we come into contact with are generally very complicated. Therefore, you must get into the habit of observing the surrounding environment and adjusting the white balance before taking pictures.

18. There are many points in the photo taken.

This is what we call noise in photos. This kind of situation mostly happens when shooting at night, 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 when shooting in low light, we often choose high sensitivity. Then, if the noise reduction system of the camera itself is not good, it will cause noise on the canvas. In order 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. In this way, the photos will be layered and the quality will be guaranteed. Of course, the premise is that you need to bring a tripod.

Nineteen, 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 digital cameras, the light has the greatest influence on the photos, and the sensitivity of most digital cameras is equivalent to SIO 100 film. Therefore, insufficient light will lead to dark photos and 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.

Twenty, the main picture in the photo is small.

It is a common phenomenon in amateur photography that the main picture is small and the background picture is large. Beginners of photography often ignore this topic. Taking pictures with a digital camera can be edited, so the quality of the original image is very important. Try to fill the picture with the main body, and don't waste precious pixels on the secondary or edited background picture.

Twenty-one, the photos printed with special photographic paper are not clear.

The quality of digital photos is directly related to the number of pixels per inch (dpi), that is, the image resolution. The more pixels, the higher the resolution and the better the image quality. In order to obtain good printing quality, the required image resolution is about 300ppi. When taking photos with a digital camera, if you want to print photos, you must use the maximum number of pixels allowed by the camera. Of course, the more pixels, the larger the file, and the fewer photos are placed in the camera memory.

Twenty-two, the printed image is fuzzy, gray and oversaturated.

The photo was taken normally, but the printed image was blurred, gray and oversaturated. This is mostly because the paper used does not meet the requirements. The type of paper used to print an image has a great influence on the quality of the image. The same image looks beautiful when printed on special photographic paper. Print clearly and brightly on copy paper; Printed on cheap multipurpose paper, it will appear fuzzy, gray and supersaturated.
