Silver Efex Pro offers an excellent way of processing images into black and white. There is a large selection of presets available varying in contrast, tone, key, and traditional film effects. And as with all Nik Software plugins you can also maintain precise control with micro adjustments to brightness, contrast, structure as well as the ability to control specific sections of an image with control points.
For those who grew up shooting film (or those stubborn enough to hang onto the benefits of still shooting film) you will be pleased to be able to apply your knowledge of coloured filters and replicating film type with specific grain and contrast capabilities of your favourite films including Kodak, Fuji, Agfa and Ilford.
For the shots above i've chosen a "Film Noir" preset then custom adjusted get the gritty contrast and reduced tonal range with the degraded / bleeding edge that used to add that fine art touch.
Again these three shots were taken during my recent trip through Rajasthan India, with the two portraits taken in Ranthambore and Ranakpur and the landscape taken in Jaipur.
