What are different image editing techniques?
Image cropping is one of the most common image editing techniques, which allows you to remove unwanted and distracting areas from an image. Thus, it helps enhance focus and improve composition. However, we should avoid excessive cropping as it can affect image quality and resolution.
This is the simplest photo editing feature that every image manipulation library offers. Adjusting the brightness is particularly helpful for photos taken in dimly lit areas. It is also used to adjust the lighting of pictures that are too bright. Since changing brightness affects all parts of the image equally, achieving the right level to improve the visibility of darker areas of an image while ensuring other areas aren’t too bright can be challenging.
When you adjust brightness, you usually need to adjust contrast as well. It essentially allows you to enhance highlighting in your images. Decreasing contrast provides a flat and even tone, whereas increasing it will sharpen your image.
Saturation deals with image colors as it allows you to enhance or reduce the color intensity in your images. If you want to make your photos more vibrant, you can increase the saturation. However, If you want faded colors, decreasing the saturation will help. Moreover, you can desaturate an image completely if you want a black-and-white image.
Filters are the quickest and easiest way to enhance your photos and make them more attractive. Today, a wide range of filters are available, allowing you to add special effects to your photos. When you use a filter, you typically don’t need to adjust the contest, brightness, and saturation of the image separately.
In addition to the above-mentioned basic image editing techniques, you sometimes need advanced editing features. For example, you might need to add watermarks to your images, detect and highlight faces in an image, etc.
