this is cool, i'll have to do some thinking about it, i've always liked optics, but i've never had the chance to really study it properly and fully |
|
| |
it's not the camera idea that i like most, but the turning a colour image into a black and white one using just optics idea |
|

Digital cameras have this. I can speak for Sony Mavica as that is what I have. It comes with a B+W, Sepia, Solarize and Neg-Art as picture effects. Nifty. With 35mm, I believe looking through a green filter gives one a reasonable idea of the B+W end product. |

Definitely doable with a digital camera, you just need a B&W viewer on the back*, or a B&W mode selection for the viewer. |
|

I think it won't ever be a popular product (artistic stuff never is, otherwise it's not art), so you're talking hugely expensive. This might be a feature on an upscale digital SLR |
|
| |
(*or, on the other hand, it might be a way for a cheap digital camera maker to cut costs.) |

You cannot convert full-spectrum light into true black and white using optics. Cameras like the upper-scale Fuji Finepix digitals offer digital through-the-lens Electronic Viewfinder, but no B&W mode. Many Sony models do offer B&W, but you'll have to watch the LCD display for the effect. |

Some Cannons and Nikons have a B+W mode, also sepia and other things. |
