Not a real problem, but unprofessional indicates separate code maintenance. I also don't quite understand why the first main function is listed in the stand-alone executable under a different name: just Focus. Not that I'm missing them in the plugin - they are of marginal usability at best it just looks bad. I'm at a loss trying to explain why those extras are included only in the stand-alone version. The stand-alone version adds three more: Defocus (adding blur), Increase Resolution (upsampling), and Despeckle (removing dot structure from images of printed matter). The plugin offers just two functions: Fix Out-of-Focus Blur and Fix Motion Blur the names are self-explanatory. I'm using it with Paint Shop Pro 20 without a glitch. The plugin works with a number of Mac and Windows applications other than Photoshop. The distribution package includes two versions of the software: a stand-alone executable and a Photoshop plugin. I know nothing on its performance, as I don't use Adobe products. The Smart Deblur filter, introduced ten years or so ago into Photoshop is said to use deconvolution, too. While this impacts both the accuracy of solutions found and the speed of the process, I still have high expectations from this method, compared to "classic" ones. The model used in Focus Magic is very general in particular, it knows nothing about the lens used, or aperture. The name suggests that defocusing is a major part of the model used. This technique uses a model of how the blur (or other image flaw) is created, trying to find the "before" image best fitting, after adding the effect, the "after" one. How does that differ from sharpening, to which we've got used in the last twenty years? I believe the different naming is used to stress the fact that Focus Magic uses a more modern method of restoring the image, called deconvolution (I'm almost ready to write a separate piece on that). Its main purpose is to reduce the out-of-focus blur in photographic images.
Focus Magic is a software product, developed and sold by Acclaim Software of New Zealand (their sole product).
