Edit experience for transformation of digital content
Techniques for edit experience for transformation of digital content are delivered in a digital medium environment. According to various implementations, an image editor system receives edits to a digital image to transform the digital image and generate an edited image. An edit experience is then generated that is presentable to recreate the image transformation process. The image editor system outputs the edit experience to enable a user to interact with the edit experience to reproduce the image transformation, such as via a step-by-step process. In at least some implementations, edits to a particular digital image are saved as presets that can be suggested for editing other images, such as images that are determined to be similar to an edited image. |
