    Hi Mike,

    You can set the effect parameter to unsharp_mask ( e_unsharp_mask in URLs) to sharpen the image using the unsharp mask filter.

    The default values are:

    Radius - 0.0

    Amount - 1.0

    Threshold - 0.05

    Cloudinary supports customizing the sigma (level range: 1-2000, default level: 100), so that a 100 value is equivalent to ImageMagick's 1.0. 

    For example:,e_unsharp_mask:400,h_80,w_80/horses.jpg
