Image editing and post-processing techniques have matured over the years, making it difficult (verging on impossi­ble) to assess whether an image has been digitally enhanced or doctored somehow. However, complex manipulations still rely on skilled user input, painstakingly painting over pixels. We present our recent and on-going work on advanced image editing techniques, extending current tools by leveraging the limitations of the human visual system and the wealth of information available in a high dynamic range image. Working in perceptual space, psychophysics plays an important role in assessing the validity of the results.
