At long last, my review of Ichikawa software's "SilkyPix Developer Studio Pro v8" has been published on the "Dear Susan" website.
It gives an overview of SilkyPix and it's features and controls, how to use it, and compares the quality of results with Capture One.
I have used it for several years on raw files from a number of cameras including Fuji X system, and always found the quality of the results.
Please take a look at the article and feel free to leave some feedback over at Dear Susan.
