Photoshop CS3 CS4 CS5 Easy B&W Conversion
CS4 & CS5 make converting images to B&W very easy with the Black and White Adjustment layer. And of course, any editor that has a Channel Mixer can do an excellent job of converting. But here is the way that I prefer for Photoshop because of how it saves tonal range.
1. Create a white fill layer UNDER the target image
2. Change the blend mode of the TARGET LAYER to Luminosity
You can play with masks, different fill colors etc but most of the time I am satisfied with the initial results.
Have fun and !Go Pack Go!
