How can I get this kind of deep Black & White picture?

[Kelvin Huggins]

I'm a newbie, so please be patient. I appreciate white as reference in this picture

Black and white adjustment layer and move the red slider up for whiter or down for darker and tweak with the rest

maybe add a slight contrast or levels adjustment as well

There are many, many ways to get deep blacks in Photoshop. I interpret your question as how can I darken an already dark tone, but not change lighter tones. The standard way to do this is using "curves". Just Google {curves photoshop tutorial}, and you will find many different hits such as:

I don't think you should be thinking about plug-ins just yet, but you should know that there is a commercial plug-in whose sole purpose is to give deep blacks. You might find the writeup very instructional:

For a quick and very dark looking effect try thresholds adjustment, if that is what you was after?

ctrl+shift+u, then play with brightness and contrast

Tom I read the tut, and of course histograms come up. Do you have a tut or info on using the histograms for seeing the image?

I think thats what I mean ?
