My two cents worth:
Shoot color then convert.
I used to use the recipe below. Really like the results. I still think it’s relevant, but Nik Silver Effects Pro is faster.

1. Open the image, assuming that its RAW, make your Lightroom or ACR adjustments;
2. Once the raw image is open in PS, select Lab Color under Mode;
3. Once open in Lab Mode, under your channels pallet, highlight the Lightness Channel;
4. Go back to Mode menu and select Gray scale, PS will ask you to discard other channels, click “Yes”;
5. Now hold your CTRL key and while holding your CTRL key, click the gray channel that should be highlighted in your channels pallet. You should now have the dancing ants at this time;
6. Now select Inverse in your Selection menu;
7. Convert back to RGB Mode under the Mode menu;
8. After converting to RGB, go to your layers pallet and at the bottom, click on create new adjustment layer (the B&W Circle);
9. Choose solid color and pick the color that you want if you want to add any color, if not, choose a neutral gray;
10. On the upper layers pallet, choose multiply and the adjust your opacity and curves;
11. Do your final processing and print.
