I have this software, which I purchased (at a significant discount after it had been discontinued by Tiffen) in order to compare software-generated effects vs. a variety of 'soft filters' (various mesh density and color, mini surface lenticular filter, genuine Softar, etc.) which I have not yet done a full set of tests. But I have one informal shot of my 97yo mother, and provide 1) that shot unaltered, then 2) applied thru the Tiffen SoftFx software, and 3) the Tiffen Haze software.
I generally like the Soft Fx actual filters in various grades, for removing some of the skin wrinkles without excessive general deterioration of detail, such as the hair. This software-generated effect seems very reminiscent to use of the filter set, but I should shoot a series, without filter and then with various SoftFx filters, and other soft filters that I have, and then apply the software to the unfiltered shot to compare directly with the real filters over the lens.
I do not like the Tiffen Haze software filter effect, particularly because it seems to
enhance saturation with increasing filter intensity, rather than increasing a haze/softer contrast effect...odd?!
You could also experiment simply by huffing on the surface of a filter, shortly before taking a shot, and again after 5 seconds and the fogged filter is partially clearing.
