Almost every photo needs some type of retouching.
Some of the different types of retouching.
Photo retouching consists of many types of commands that can be applied to an image to increase the quality of the photo. No matter how professional or experienced a photographer may be, an art director with a trained eye can always point out areas of any given photo that require some sort of retouching.
Correcting flesh tones, eliminating backgrounds, airbrushing shadows and adding contrast and color are some of the most common forms of retouching. Being that all images on the internet are ony 72 pixels per inch (low resolution), contrast is always added to make it sharper.
