There are three parameters that change depth of field (dof): focal length of lens, f/stop, and distance from lens to the focus point. There are several free apps that you can download for your computer or cell phone. I use one all the time to ensure that I get the dof wanted. Play around with the app and you'll get a good idea of what you need to do.
I'm always amazed, being a member on ten or more different sites, that so many folks never take the little extra step to include the name of, or the site address and what phone, i.e. android or iPhone or Win8.1, these apps are.
