1. Contrast and brightness are two of the core elements that aid in creating a visually appealing image. Contrast is the difference between the lightest and darkest elements of an image. Increasing the level of contrast in an image can often help to make it stand out more, creating a more dynamic and vivid appearance.

2. Brightness is a measure of the amount of light being emitted from an image. It can be manipulated by changing the lighting of a photo, or by making adjustments to the exposure settings of a camera. Increasing the brightness of an image can often make it appear livelier, or help it to stand out more against its surroundings.

3. Contrast and brightness are two important facets of any image, and manipulating them properly can help to make a great photo. High contrast images, such as photographs of a city skyline, are great for making the scene stand out and providing a striking visual impact. Lower contrasts, such as photographs of nature, are often used to invoke a feeling of tranquillity and beauty.

4. Increasing the brightness of an image can make it appear more vibrant, and make the subject of the photo stand out more. For example, brightening a portrait can give the person in the picture more life and personality. However, too much brightness can have an opposite effect and make the photo seem washed out or artificial.

1、对比度：是指两个比较的物体之间的明暗差异大小，是衡量影像物体的层次结构的重要指标。它表示比较物体之间连续色调的差异强度。一般来说，处理图像所需要的对比度越高，所反映出来的层次越清晰，显示效果也越好，色彩也更加深厚。

2、亮度：是指物体发出的光线强弱程度，即物体颜色色调明暗程度。它表示比较物体之间连续色调的明暗程度。通常用字母‘L’来表示，一般色调偏暗的称为低亮度，反之，色调偏亮的称为高亮度。亮度的调节也会受到对比度的调节影响，当改变对比度时，色调偏暗的部分会越暗，色调偏亮的部分会越亮，整体显示效果也更好。
