Like camera lens,glasses,or a prism. If you need to see an object in black and white, try putting it in a room where the light is controlled by a rheostat, and turn the light down to the point that you can barely see it. The cones that make our color vision work don't do well in low-light conditions.
If you need to see an entire scene, then a pinhole camera may work best; it likewise cuts down on light, and help you use only the rods that allow us our black-and-white vision. A black and white studio camera.
An old camera with a black and white view finder
Owls have no cones they see only in black and white. There must be an optical way to remove the cone ability in the eyes by a type of glasses.
Maybe a 3D pair of glasses that filter all other colors.

Some kind of monocrome lens
This is closer
To shoot the world in black and white, you have to see it in black and white. The skills required is not easy. You need to visualize the world in shades of gray instead of contrasts and harmony between colors.
One solution to this problem is by using the SRB Monovue filter. It helps suppress colors and make tonal relationship more obvious. Yes you can use red or orange filters to help suppress colors but those will also distort tonal relationship.
Most digital compacts, however, have a mono mode, which most SLRs do not, that can display a black and white version of a scene.
Its sort of like putting a color picture on a copier and it comes out black and white
This is an interesting question.
It would be great to invent a type of sunglasses that filters out all colors.
You can also filter out wave lengths
1. Shoot in color. Digicams grab a wider range of tones in color mode because they're capturing data for three channels - red, green, and blue. Convert your images to black and white in postproduction.
2. Light at an angle. Head-on lighting often results in flat, low-contrast images. Instead, try to have the light hit your subject at an angle. This highlights one side and throws shadows on the other.
3. Adjust exposure manually. Identify the key element in your image and decide how dark you want it (light gray, or whatever). Then over- or underexpose the shot until it has the tonal value you're going for.
4. Use Photoshop's Channel Mixer. To maximize contrast and impact, convert your images to black and white with the Channel Mixer. It lets you select the best tones from the red, green, and blue information in the file.
Optical Surgery maybe
Let me know if you figure it out! |
