Hi Roger,
There are in essence two approaches: routines that depend on some "unsharp masking approach" and "deconvolution".
- "Unsharp masking": Those got quite sophisticated (e.g. SmartSharpen, Lens Softness correction) with varying degrees of "correction" throughout the image to achieve a "perceived edge-to-edge sharpness". As the aberrations increase (I am talking optical aberrations) these approaches will yield "less perfect" solutions as they "can not describe the complex nature of larger optical aberrations" accurately. But they can account for varying degrees of sharpness across the image. Advantage: it's fast.
- "Deconvolution". Deconvolution involves a two step process: first determine the aberration, describe them (piccure+ does so through PSFs) and then reverse them. The aberrations are usually assumed to be a) either the same across the image (doesn't work for optical aberrations) or b) have a specific shape (also doesn't work well for larger aberrations). piccure+ is the only solution capable of determining (complex) optical aberrations which are not the same across the image (less sharpness towards edges) and vary in shape. Advantage over "lens profiles" is that the "modeled over true error" is minimized as the optical aberrations are determined for the image itself uniquely. Thus also works for "self built lenses", scans, etc.
piccure+ has a more complex approach in determining and reversing the optical aberrations. So bottom line is: the programs mentioned are not using the same technology and the results won't be the same. For small aberrations, it may be hard to always tell the differences between "unsharp masking", "deconvolution" and the respective software solutions. But at "fast apertures", "full-format" camera owners will be very happy with the piccure+ results - especially in the edges...
As for the price increase: current pricing is 129 USD (+VAT in the EU; can't change tax...). That constitutes a 18% increase over it's introduction price. People kept telling us "I care less about the price but more about the speed and quality - make it faster". So we have hired additional people for making it faster. Our customers are primarily professional photographers which are less price sensitive and value quality and speed the most. Making it faster is no easy task, and it ain't cheap.
