A few free options mentioned are worth trying:

• SmartDeblur 2.0: specifically designed for blurred images and offers blind deconvolution plus manual modes for motion blur, out-of-focus blur, and gaussian blur. According to the shared experience, it can be slow during automatic analysis but can give very good results.
• Image Analyzer: freeware that includes tools claiming to handle deconvolution for out-of-focus and motion blur compensation.
• ImageJ: an open-source, cross-platform image-processing tool. It’s more technical, but it’s free and flexible.

A practical note: deconvolution can help only when the blur is moderate and reasonably consistent. Strong blur or complex camera/subject movement often cannot be fully fixed, and aggressive settings may create halos or an oversharpened look. For best results, try small adjustments and compare previews before processing full-size files.
