You're missing out on a lot of capability.

1) You first have to define what "optimizing the color image" means in the context of producing a grayscale rendering. An optimized rendering for color presentation is not necessarily the best way to prep for producing a grayscale rendering.

2) Conversion from one color model to another incites losses. Every time you convert to Lab or to Grayscale, you lose some data, some resolution.

3) Layers and Adjustment layers are a very effective means of making non-destructive, selective edits to images, and can be very finely tuned. An image doesn't need to have anything "horribly wrong" with it to get a huge advantage out of using layers to adjust and shape its rendering, whether in RGB or monochrome.

The B&W conversion rendering methodology presented here is a good simple way to do it, but leaves behind a lot of selective adjustment possibility.

Unless there's something horribly wrong with an image I don't "use" layers. In photoshop I convert to b&w by first optimizing the color image as much as I can. Then I use this method.

1. Create a new adjustment layer "Hue/Saturation"
2a. Set Hue to -180
2b. Set Saturation to +100
2c. Set Lightness to -100
3. Change Mode to Lab Color, (if asked, yes do discard the layer).
4. In channels delete layer a.
5 Convert to gray scale.

Adjust curves or brightness/contrast for fine adjustments.
This is the easiest method I've found, (thank Cotty, for posting it here a while ago). that gives very good results.

I agree. I'm just starting to work with layers and i'm in a coinfused state right now.(as

Help is appreciated

                Hi Gang
Apologies for 2 pictures in one week.

This is a B&W conversion of a shot taken Oct 10, 2005 of the abandoned Maynooth


Station.


Still needing more experience on this stuff.
You can see the remains of the old bed to the right.

Converted using Channel Mixer in Monochrome setting.
