This is after I adjusted the color levels to get it close to black and white, then changed it from RGB to Gray-scale.

I was attempting to regain that New Photograph look it should have had. I notice B&W Photos from the 1960's I have in my case have changed from B@W to a yellow hue as well, even though not quite as pronounced as the original shown here.

Now, my question is this, does this process increase photo clarity for you as a viewer?
