As with most plug-ins, Silver Efex has a wide range of presets and you can create your own. I often start with a preset – I like More Silver – and will try several and when I settle on one will spend time adjusting the sliders to taste. A great DxO feature is the ability to fine-tune images locally with control points that you can place in any area of the image and use as many as required.
