It is often said that you need to add contrast to images to give them more strength. It obviously depends on your intention (you may want to make an image very smooth and pastel tones), but if you want to create contrast, it's not limited to a slider in your post-processing software, or a stroke of curves.. Let's see together the 3 main types of contrast and what they bring to the composition of your images. Indeed, the composition is actually based mainly on the elements that catch the eye in the photo. It's all about balancing the areas you want to draw attention to (the eye is drawn to them if you've done your job well), and those that don't interest you (the eye is pushed back). But the is the first thing that catches the eye, even before a bright area. That is, a dark object on a light background will strongly attract the eye.
