A simple tut on better grayscale photos

There are many tutorials on making better grayscale photos utilizing many complex steps, but I always do this simple method first and if lucky, I may not have to correct much further.
Here is the starting color photo followed by the photo after changing it to grayscale in Photoshop.

Image; Mode; Grayscale
Not so great, is it?

1. A better way is to use lab mode. Open the color original. Bring the Channels Palette to the front.
2. Then go
: Image; Mode; Lab.

3. Now you'll see Lab, Lightness, A & B channels. Drag A or B to the little trash can below (or right click and choose Delete Channel)
4. Now you see: Alpha 1 and Alpha 2.
5. Delete Alpha 2
6. Important step. Don't forget to go back to MODE and change it back to grayscale at this point. I also applied: Image; Adjustments; Auto Contrast.

Your photo is greatly improved. You can tweak the levels or the brightness/contrast, or any other methods you are comfortable with. This step gets you closer to a better end result quickly.
7. Most important step: SAVE AS and give it a different name so you won't save over the color original.
