Imagine how to adjust the meter time.

1. Load the image whose contrast needs to be adjusted into the image editing software, or use the image processing library in the programming language to load the image.

2. Increasing or decreasing the overall brightness of the image will affect the contrast.

3. Increasing contrast can enhance the difference between light and shade in different areas of the image and make the image clearer.

4, according to the need, you can further fine-tune other parameters of the image, such as saturation, hue, etc. , to achieve satisfactory visual effects.
