The most effective way to enhance or edit images on the fly is on a mobile device. Since most images are taken via smartphones these days, using a quick and simple editing program like those offered by social media apps like Facebook or Instagram is a good choice. Both apps offer extremely intuitive editing tools and features like cropping, perspective adjustment, and light and color augmentation. Both apps also host an increasingly impressive variety of filters and effects that can both enhance your photos or distort and manipulate them to your own specifications.
