how to turn an image into black and white using photoshop

I first chose my image to change the colour levels to how I wanted it to turn out.

This is how my image turned out after I had changed the colour levels and after this I now wanted to turn my image into a black and white image.

I adjusted the colours after I had changed the image to black and white this allows me to decide how black or how white I want parts of the image to be.

After I had done all of that I then had to crop my image by using the crop tool, I changed the image size to 5inch by 7inch and resolution 300 this changed my image to a portrait shot which isnt ideal for the image used but atill shows how to do it.
