DVO Sharpen is an advanced sharpening tool that greatly enhances out-of-focus shots. It uses adaptive picture analysis and processing to yield excellent results without the common side effects associated with standard algorithms (such as amplified grain, noise, or halos around areas that were already sharp).

The Overall Strength parameter controls the amount of sharpening applied to the shot, while Spatial Strength and Crispness helps fine-tune the overall effect. The image Noise level will help the algorithm to avoid sharpening noise, so analyze the shot and choose a value that will better suit the image.  

The Adjust and Trim section can help you clean up specific regions of the image, with separate settings for low detail and high detail sharpness along with trimming options for highlights and lowlights, helping you to get the best results without breaking the image.
