Post Processing Sharpen sharpens an image in one of three modes: basic, smart or CAS (Contrast Adaptive Sharpening). You add one image, choose a Sharpen Mode, and get back the sharpened image.
Basic mode uses Sharpen Radius (1 to 15) and Sharpen Alpha, a strength setting from 0.1 to 5. Smart mode preserves edges. Its options are Noise Radius (1 to 25) and Preserve Edges (0 to 1). It also has Smart Sharpen Strength (0 to 25) and Smart Sharpen Ratio (0 to 1). The cas mode uses Cas Amount (0 to 1).
Post Processing Sharpen takes one image per run, and the price is 10 credits.
