Digital BW, The Print

For those that have CS3 you have the option of using the b/w adjustment
layer.  Gives you all the flexibility of what you do in Lightroom.

 

 

Also for those that use CS3 you can do the conversion in Camera Raw in a
similar fashion.   

 

My other preferred approach is to use the Channel mixer adjustment layer.
Here I look at the Channels first.decide which channel provides the best B/W
rendition for the subject manner.

 

Often I use the Red for people/classic figure,  Green for Landscape etc.

 

Once you chose the Channel.R, G or B the add the Channel Mixer Adjustment
layer.  At the top pull down menu chose your channel.RG or B.

 

The Click Grayscale in the lower left.    You now have a Greyscale image and
you can move the RGB sliders to adjust the tone of all the layers.

 

I now prefer the b/w adjustment layer.   The slick thing here is that once
you add the adjustment layer you have the option of using a number of
presets.

 

Ie:  high contrast, IR effect etc.   You can also move all the colored
sliders around.what is really slick is that you can move the cursor to a
part of your image and slide the cursor back and forth to effect only those
colors that you are pointing to.

 

As with everything in Photoshop there is an unlimited number of ways to
accomplish the b/w conversion.  There are many many more which I am sure
will be highlighted in follow posts.

Subject: [Digital BW] B&W Conversion Techniques

 

Did it fly right by me or hasn't anyone discussed their techniques 
for converting color to b&w? Urm...or maybe everyone shoots film on 
this list?

I've been using...more like learning two different, but similar methods:

LIGHTROOM
Adobe Lightroom offers two different ways to convert to greyscale:
a. By reducing the saturation of each color, you can then adjust 
the lightness of each to effect each color to be lighter or darker
b. By clicking the Greyscale tab and doing, basically the same thing

PHOTOSHOP
I've been using Hue & Saturation adjustments layers by creating on to 
desaturate all the color (I call this layer "Film") and then below it 
I place another H&S adjustment layer to adjust the densities of the 
color to get the tone I want.

I must say, adjusting the brightness of each color to change the 
density of a given color, something seems wrong about this idea. Have 
you ever adjusted one the brightness in a Hue & Saturation on a color 
image? It's like taking the black point in the curves dialog and 
brightening it. Seems to me there might be a better way.

I have played around with channel mixing but it has only been 
"playing". Does anyone else have any thoughts on this?
