I just wanted to ask you a question that has bothered me for long time.
I was reading a B/W Photography book and they had mentioned " Start seeing in BW or Visualising in BW.
2-3 years back when i had just started a member at another forum ( That forum has since closed)once had mentioned that how everyone wants a perfect way to convert from color to B/W in Photoshop , he pointed out how none of us had any experience in B/W photography and when we followed any method we did it without realising what we are doing.
I want to know when i shoot something i visualize how they look in B/W but i am not always correct, i mean i know if i use red or orange filter for shooting a portrait of a fair skin person wearing blue outfit than it will be high contrast photo as blue will get darker and fair skin will look clear and very light.
Apart from this i really cannot say how will colors in my photograph will translate into tones .
SO when i converting any color Photo into BW i am not really sure say without filter say what tone will blue adopt or say brown.
Is there a method to know how will various colors translate into different tones. I mean red , orange , yellow will always appear as lighter tones, but what about rest.
I hope i have been able to make myself clear.

You know I might be miss reading your question but try this...
Open a photo that you wish to convert to b/w in photoshop.
create a new hue / saturation layer, when the dialogue box opens just click "ok" then change the layer properties to color.
create another hue / saturation layer and this time drag the saturation bar all the way to -100. You should now have a b/w version of your photo. Click "ok" on this box to close it.
Go back to your first hue / saturation layer and open it back up, you can now adjust the hue back and fourth, this should show you what different "colors" will look like in a b/w photograph...
If I've made no sense at all please feel free to PM me and I'll give a more detailed example of what I'm trying to say..

I know how to convert from color into BW.
My Point is that i need to know before i shoot how will each color convert into tone so that when i convert i am able to do convert properly.
Example
I know when i convert a fair skinned person wearing blue shirt and say blue jeans using a red or orange filter what the output should be i.e. i can visualize this in my head, i cannot do it for every other color.
I mean what if is he wearing green and brown, what tones will these colors assume? i dont know so that what bothers me |

If you are using CS2, Method Four - Photto Filter/Hue-Sat will really help you understand how different filters affect conversion.

I got ya... ok...
1. the color of the filter you put on the camera, everything in the scene which contains that color will be rendered lighter.
2. the complement of the color filter on the camera, everything in the picture which contains the complementary color will be rendered darker.
The same goes for digital "filters" used in B&W conversions. When converting to B&W you are only keeping luminance, thus complimentary colors = black and same color = white.
Some complimentary colors: red and green, yellow and blue, orange and purple. Some photographers use a green filter for black and white portraits of people taken outdoors to darken the flesh tone.

I think it means to see in terms of light and shadow.
Don't worry about what the colors convert to. Adjusting RGB mix in post takes the place of colored filters.

Well they meant to visualise in terms of tones i.e. how some situations are great for BW while some are not , difference is i guess range of tones in each scene
