Using a filter holder + Cokin filters you can play with black and white the good old way. First I tried with filter and then I tried the photoshop / lightroom way – I used the predefined color filter option that is available in photoshop in order to make a fair comparison. Click for “the big picture”. The black and white “real” images are made by using the monochrome wb option inside SPP. And yes, it could have been a more intresting scene but it works. You get similair result directly from camera if you select in-camera black and white jpeg mode. see this image.
When I bought my mini cokin A (amature) holder then I bought some filters at the same time. All ND’s were sold so I had to buy some colorful ones instead. One was called tobacco or coffee grad – can’t remember what word they used. Both works. :) And I have done several black and whites with it on and it works great. One cool thing is also that when you put camera into black and white mode (jpeg) and use a filter such as this you get really nice nice results directly out of the camera. Feels cool too when you aim as you see the result directly on the LCD.
