I have been watching this thread with interest but keeping quiet, but as the thread and techniques have progressed I now feel like I have to pass an opinion and ask a question. The opinion I have is, those first two images output and posted by Michael to me looked the best, so this leads then to the question, can we still have that simple output method ?
