Canon 600D SLR camera is overexposed.

First, the main reasons for the failure caused by camera overexposure:

1. The lens barrel was deformed due to collision.

2. Due to the lack of maintenance, there is too much sludge, too much dust or rust in the shutter assembly, which will affect the normal operation of the shutter.

3. The lens blade of SLR camera is stained with oil and cannot be opened and closed normally.

4. The camera is flooded.

5. The telescopic belt in the zoom lens of a small digital camera is broken, which will lead to the failure of the aperture.

6. The ambient temperature is too low, which makes the camera unable to measure light normally, and the aperture and shutter cannot work normally.

7, the environment is too humid, it will also cause the camera parts to rust, or the lens is moldy, which will affect the normal metering and exposure of the camera.

8. The power supply of the camera battery is insufficient, and the shutter group cannot work normally.

9. If the traditional camera is not used for a long time, or the lubricating oil is dry, it will lead to abnormal work.

Second, the solution:

1, you can adjust the focal length and focus on your face or some light-colored objects, which may be better.

2. Correct the exposure by manually modifying the aperture and shutter values.

3. There is a very simple way to adjust the exposure compensation (press the key combination to adjust the exposure compensation (EV+ dial)), where+means overexposure and-means underexposure.

Common troubleshooting of SLR:

Symptoms: The SLR is underexposed.

Because of the urban theme, this photo contains all the color mixtures, which is different from the traditional landscape photos dominated by brown. It is impossible to control the noise of this image, but it can easily solve the problems of underexposure and color balance.

Solution:

1. To adjust the JPEG images taken by popular cameras, first sharpen the images, and then convert them into 16-bit mode. Adjust the image pixel size, reduce the size to 7 1%, and set the "Adjust Image Pixel Size" mode to "Quadratic Body".

Histogram shows that most of the recorded images are lower than the middle gray level. Notice the thin histogram lines that extend all the way to the white area slider. This is the image data composed of several bright light sources in the photo, which is the light source formed by the raindrops near the camera being irradiated by the built-in camera flash.

The histogram shows that these highlights only account for a small part of the image. Keep the details in these highlights, regardless of the overall quality of the image.

2. Drag the white field slider to the left until it touches the main histogram protrusion. This can significantly highlight the image and avoid losing all the highlighted details in the main image area.

3. Underexposed digital photos will contain a lot of noise. Histogram can't tell the difference between actual image information and random noise, so it is necessary to reduce noise by increasing clipping value and let Photoshop recalculate the actual image information.

Depending on the image type and the desired effect, the new editing settings may be quite different. Fortunately, the monitor can display the effects of all new settings in real time, and you don't need to confirm the settings. You can try several times to find the settings with satisfactory results.
