Abstract

SmartPhotoCrafter automates photographic image editing by combining image quality comprehension with targeted enhancement, using a reasoning-to-generation approach that eliminates the need for explicit human instructions.

Traditional photographic image editing typically requires users to possess sufficient aesthetic understanding to provide appropriate instructions for adjusting image quality and camera parameters. However, this paradigm relies on explicit human instruction of aesthetic intent, which is often ambiguous, incomplete, or inaccessible to non-expert users. In this work, we propose SmartPhotoCrafter, an automatic photographic image editing method which formulates image editing as a tightly coupled reasoning-to-generation process. The proposed model first performsimage quality comprehensionand identifies deficiencies by theImage Critic module, and then thePhotographic Artist modulerealizes targeted edits to enhance image appeal, eliminating the need for explicit human instructions. Amulti-stage training pipelineis adopted: (i)Foundation pretrainingto establish basic aesthetic understanding and editing capabilities, (ii)Adaptation with reasoning-guided multi-edit supervisionto incorporate richsemantic guidance, and (iii) Coordinated reasoning-to generation reinforcement learning to jointly optimize reasoning and generation. During training, SmartPhotoCrafter emphasizesphoto-realistic image generation, while supporting bothimage restorationandretouching taskswith consistent adherence to color- and tone-related semantics. We also construct a stage-specific dataset, which progressively builds reasoning and controllable generation, effective cross-module collaboration, and ultimately high-quality photographic enhancement. Experiments demonstrate that SmartPhotoCrafter outperforms existing generative models on the task of automatic photographic enhancement, achieving photo-realistic results while exhibiting higher tonal sensitivity to retouching instructions.
