The underlying neural networks were trained using professionally retouched photos, including the ones submitted by the community. The plug-ins resulted from eight years of photo retouching experience and two years of studying deep learning. Retouch4me plug-ins were developed by Oleg Sharonov, the author of 3D LUT Creator (a tool for professional color grading). Retouch4me is a family of artificial intelligence-powered plug-ins for photography and video retouching, compatible with Adobe Photoshop Adobe Lightroom, and Capture One (as external editors).
