| In my home studio I have a black backdrop. In some photos the black background doesn't look BLACK enough it gives off a small tint and in other photos it's PITCH black the way I want it when doing portraits.. what is the key to keeping that black background BLACK at all time when shooting portraits of children, people ETC. . . |

Is your White balance right ? if its not at the correct point, you will not see black ( but may be some red/magenta added to the black background). If you use the same setup everytime, then you should manually fix your white balance ( to the value which gives you correct black background )

Figure out what your exposure is set at when the results come out the way you like them and keep it there.

One easy method would be to
1. duplicate layer
2. use Select Color tool to select background ( I am hoping your subject is not that black as background )
3. make a mask on the duplicate layer and photoshop will automatically make the mask using the selection, if it doesn't work that way, copy selection and pase on mask
4. Now you can do anything you want, like darken this duplicate layer or paint it black

Manage your light fall off. Barn doors, snoots, and softboxes used at different angles and height will help with light fall off. The more you can keep on your subject and the less that fills onto your backdrop the better.
If you go into PS and adjust the backdrop to black, but you have a similar tone in your subject, but it's not really black, then you're going to end up changing the tonal range of your subject, which is something you don't usually want to do.
